BRICK PAVER INSTALLATION IN VEHICULAR AREAS PART 1 -GENERAL 1.01 Conformity Conform to. the requirements of the general conditions of the contract. 1.02 Work Included 1. Supply and place
bituminous setting bed. 2. Supply and install brick pavers in quality, shape, thickness and color as specified. 3. Supply and place all accessory items as required by the contract. 1.03
Product Handling Brick pavers sball be delivered and unloaded at jobsite on pallets and bound in such a manner that no damage occurs to the product during handling, hauling and unloading.
1.04 Project Conditions Eovironmental requirements: Ambient and surface temperatures: Minimum 35 degrees F for minimum 48 hours prior to and during construction. 1. Area to receive bituminous
base must be dry. PART 2 -MATERIALS 2.01 Asphalt adhesive will consist of 2 percent neoprene (grade WM), oxidized asphalt 80 penetration. 2.02 Joint and filler to be pigmented Portland
Cement (ASTM C-50). Sand to conform to ASTM C-33. 2.03 Mixes: a. Biruminous Setting Bed: The fine aggregate to be used in the bituminous setting bed shall be clean, hard sand with durable
particles and free from adherent coatings, lumps of clay, alkali salts and organic matter. It shall be uniformly graded from 'coarse' to 'fine" and all passing the number 4 sieve and
meet the gradation requirements when tested in accordance with the standard method of test for sieve or screen analysis for fine and course aggregates ASTM Designstion C-36. The dried
fme aggregate shall be combined with hot asphalt and cement, and the mix shall be heated to apprOximately 300 degrees F at an asphalt plant. The proportion of materials shall be seven
(7) percent cement and ninety three (93) percent fine aggregate. Each ton sball be apportioned by weight in the approximate ratio, 45 pounds (Ibs.) asphalt to 855 pounds (lbs.) sand.
g:\proj\OII82204\rma1\jx;vcr 
b. Neoprene: Modified Asphalt Adhesive: Consist of two (2) percent neoprene (grade WM) oxidized asphalt with a 55 degree softening point. (80 penetration) and ten (10) percent long fibers.

are free from structural defects. b. Elevation is such that when setting bed and brick paver are placed, the top surface of the pavers will be the required finished grade. C. Paver surface
shall be completed to established elevations without ridges, voids. or other obstructions that would interfere with installation of brick pavers or asphalt. 3.02 Edge Restraint: a. Vehicular
Paver: Pavers in vehicular areas will be restrained in all directions by the depression in street pavement provided by the paving contractor per detaIls on plans, requiring no special
work when pavers are installed. b. Check all restraint systems for proper location and elevation per plans and specifications. 3.03 Preparation: a. Prime concrete slab with rapid curing
cut back asphalt (m-81), at a rate of .1 gal/square yard. 3.04 Application: a. To instaIl the setting bed over the base, place 3/4 inch deep control bars directly over the base. If grades
must be adjusted, set wood chocks under depth control bars to proper grade. Set two bars parallel to other. approximately eleven (11) feet apart to serve as guides for the striking board
(2 foot long, 2 inch by 6 inch board). The depth control bars must be set carefully, to bring the pavers, when laid, to proper grade. Place some bituminous bed between the parallel depth
control bars. Pull this bed with the striking board over these bars several times. After each passage. low porous spots must be showered with fresh bitominous material to produce smooth,
firm and even setting bed. As g:\prnj\01 J82204\fLnal\paver 
soon as this initial panel is completed, advance the first bar to the next position in readiness for striking the next panel. Carefully fill any depressions that remain after removing
the depth control bars and wood chocks. The setting bed shall be rolled while hot with a power roller to nominal depth of 3/4 inch for vehicular areas. The elevation will be adjusted
so that when the brick pavers are placed, the top surface of the pavers will be required f!Dished grade. b. A coating of two (2) percent neoprene -modified asphalt adhesive shall be
applied by mopping or squeezing or toweling over the top surface of the bituminous setting bed so as to provide a bond under the pavers. If it is troweled, the trowel sball be serrated
with serrations not to exceed one-sixteenth (1/16) of an inch. C. Installation of brick pavers shall begin when the modifted asphalt adhesive is dry to the touch, carefully place pavers
by hand in straight courses with hand tight joints and uniform top surface. Good alignment must be kept, and the pattern shall be that sbown ont he drawings. d. If additional leveling
of the pavers is required, and before sweeping in joint filler, roll with a power roller after sufficient hear has built up in the surface of the brick from several days of hot weather.
e. loint Treatment: Hand tight joints (shall read from 0 inch to maximum 114 inch). Sweep a dry mixtute of one part colored portland cement to match color of brick pavers and three parts
sand until joints are completely filled. Fog lightly with water. Cement stains that remain shall be cleaned with a 10 percent solution of muratic acid or mortar cleaner. 3.05 Proteetion
a. Newly laid pavers must be protected at all !hues by panels of plywood on which the installer stands. These panels of plywood can be advanced as work progresses. However, the plywood
protection must be kept in areas which will be subjected to continued movements of materials and equipment. These precautions must be taken in order to avoid depressions and protect
paver alignment. ***END OF SECTION*** g:\proj\O! 182204\fwJ\p3-Wlt

THE ADDISON CIRCLE "Residential" and "Mews" Street Classifications The secondary streets for the proposed Addison Circle Development, which in the project documentation are referred
to as "Residential" and "Mews" streets, have been reviewed using the Portland Cement Association publication, "Design of Concrete Pavement for City Streets" to determine the optimum
pavement thickness. Input parameters for this design method include the following: Modulus of subgrade reaction, k = 150 psi/in. (lime treated, high P.I. clays) Concrete flexural strength,
MR : 650 psi @28 days Pavement design life periods reviewed: 20 years, 35 years, 50 years Traffic using these streets will predominantly consist of automobiles, although we have made
some assumptions as to truck traffic which may also be present. Since there are business units located on McKamy Avenue just west of Quorum Drive, we have assumed there wiil be several
delivery vans entering and leaving the area each day. We have also assumed weekly dumpster and full-size moving van traffic, as well as daily bus traffic. The average number of daily
heavy commercial vehicles (2-axle 6-tire and heavier), including construction traffic in the early stages of the development, is estimated to be thirty, which falls at the top end of
the design charts. Because these are "Residential" streets, the load safety factor is 1.0, which is a basic level of conservatism. Using the design charts from the PCA manual (copies
attached), the required thickness for the parameters listed above is just over 5.5 inches for a 20-year life. Looking at the required thickness for 35 and 50 year designs, the charts
also indicate just over 5.5 inches is required for each, which suggests that the thickness is not sensitive to this relatively low level of heavy vehicle traffic. Construction traffic
may be using the pavement pavement during the early weeks of its life. Once the pavement design strength has been reached, constrnction traffic should not be a problem; in fact, lighter
construction vehicles may use the pavements before they reach this design strength. Expected construction traffic consists of ready-mix concrete trucks, material and equipment delivery
trucks, and construction equipment. The heaviest construction vehicles, including ready-mix trucks, cranes, and other vehicles with single axle loads of 18 kips or more, should not be
allowed to use the new pavements until the design strength of 650 psi is reached. Lighter equipment such as front end loaders and other pneumatic-tired vehicles may be allowed to use
the pavements after 14 days, while pickups and light construction vehicles may be Oartas I Fort Worth /Houston I EI Paso I Phoenix I Tustin I Ontario I San Clemente 
allowed on the pavements after 3 to 7 days. The construction traffic is accounted for in the design traffic analysis. Based on the stated parameters and assumptions, we believe that
the pavement for the "Residential" streets and "Mews" streets of the Addison Circle development should be constructed using 6 inches of concrete over a lime treated subgrade. HUITT-ZOLLARS,

01-1822-04 Dear John: I am transmitting herewith 3 copies of our [mal version of the design report for the modem roundabout at Addison Circle. This report supports the geometry and other
design details that are now reflected in the construction plans and reduced copies of the most relevant plans are included therein. While the report itself does not specifically respond
to the comments that have been made by Barton-Aschman, the design does address most of those comments, such as the location of the crosswalks and the proximity of parallel parking to
the circle. It does not, however, reflect any changes to increase the level ofservice or the confidence level of the traffic projections. Per our meeting with you, the City Manager and
others on January 19th, we believe that the traffic projections are conservative in many ways and the Town does not want to further compromise the urban pedestrian enviroument by expanding
the roundabout to handle more traffic. Also enclosed is a signed, sealed copy of the report which supports reduction of the pavement thickness in the mews and residential streets from
8 inches to 6 inches. There are still a few outstanding items in the project design but none of them is critical to beginning the construction. These items and their proposed resolution
are as follows: • Roundabout Lighting Peter Doctors is currently performing the final photometric analysis of the roundabout based on our selection of fixtures that are consistent with
the existing tall fixtures on Quorum and Mildred. The Gibson contract, however, already includes items and quantities for the required conduit and light pole bases. All that remains
is to precisely locate the fixtures based on the photometries and supply a revised plan to the contractor. T.V. Electric will supply and install all of the fixtures. G,IPROJ\OI182204\JB0322.LTR

Mr. John Baumgartner March 22, 1996 Page 2 • Tree Lighting Once the transformer locations for the development project have been fmally decided we can complete the electrical design for
lighting the trees. The Gibson contract has an allowance for the conduit and hand holes but we must still supply them with a plan showing the locations. A separate contract will be let
for the electrical cable, connections and outlet installation (probably along with the Bosque Park work). • Bosque Park This design is currently being completed by Newman Jackson Bieberstein
(ponding outcome of transformer locations) and should be ready for bidding in June. • Private Utilities We have received this week a plan showing the conceptual layout of the private
communications conduit system in the public streets. We are providing some specific direction for that contractor to complete his construction documents. This information will not be
reflected on the Town's construction plans but will be supplied to Gibson for coordination purposes. The fmallocations of the facilities could, however, be shown on the As-Built plans
for the Town's project. Please let me know ifyou are aware of any other outstanding issues. We are working with Clyde Johnson to prepare final contracts and will provide sets ofplans
issued for construction following action on any comments you may have on the set you are currently reviewing. Sincerely, HUITT-ZOLLARS, INC. Engineering! Architecture ACO/psp cc: Bryant

Baumgartner, Town ofAddil!lm Slade Strickland, Town ofAddison BryantNail, Columbus Realty Trust Paul Shaw, Newman, Jackson, Bieberstein 1willbe out orthe omoomost of the day on Wednesday
and did not want to wait any 10.JWll"to address this issue. Therefore, I felt it best to communicate withall ofyou at once and allow you to review the information so we can talk latsr
and try to resolveit. On last Thursday, March 28th, at 9:00 A.M. Built-ZoUars received a FAX from the Town tnInl:ImittiDg the attached comments to the Ilmdscllp6 and irrigation phms.
The comments lreJ.'C in turn transmitted to Newmlm. Jackson. Bicberstein that mol'Dingto be addressed. I did not personally see the comments at that time. It is my understundingthat
Paul Shaw spoke with Slade Strickland later and it was IlgI'll!ld that no changes were requiredon the plantiDgandfurniture plans that wouldresult in Ii contr:mt modificationmr Gibson.
However, the changes to the irrigation plans were not resolved. From my conversations with Paul on Friday, the irrigation comments soundedsubstantive enoogh to cause II change in thecontractor's
lIOOpe ofwork and I instructed Paul not to make any changes to the plans until I had reviewed the comments andtheir possible cost consequences further. I spoke withBryant later and made
him aware of this, telling him that. I had not yet !lI!en the comments myself but wouldnot be issuing a change onie1' withbut talking to him and the Town first. I read the comments onTuellday
whllllPaul and Bryant were outoftown andI called Slade too late inthe day to di9CWilll th.em withhim. The memo from Slade transmitting the comments indicates that some of them hlld previously
been transmitted but had not been reflected on the plans. He suggests that the changes could be made withoutplan revisions butthat the contractor should be made aware oftbem now. This
implicsthat they a.re ofa nature that willcause a 􀁣􀁾􀁥inthe lIOOpe and possibly the cost of the woik. After reviewing them, I have no doubt that they willaddcost to the project. Ifthese
items were not considered in 
the bidI believe we are aD better served to change the plans and give the contractor an opportunity to review the changes with I'0Bpect to his bid. I have several questions .•• • Were
these conunents mllde previously and. if so. were they conveyed to the contractor liS part ofone ofthe ad.dendajust like many of the civil comments that were not, at that time, refleeted
on the plaml? Perhaps we are just deating with creatbtg« confurmed sct ofdocumenta. • Ifthe comments are new to the I:ontractor, are they substantive enough to cause II change in the
price? • How should we})1"OOtlf.ld. considering our strained relationship with Gibson and the tikeliboodthat every additive change order will be used to take advantage of the owner'!
Since it may take some time to resolve this, I have inBtzucted David Meyers to issue the constn.wt.ion sets without the irrigation phIDs. Please discuss this ifyou have the opportunity
and letme know how we should proceed. I should be in the oftlce by 2:00 P.M.

DATE: April 8, 1996 RE: Addison Circle Phase I Public Infrastructure FROM: Andy Oakley, Huitt-Zollars, Inc.1sz-o-TO: Bryant Nail -Columbus Realty Trust John Baumgartner -Town of Addison
Paul Shaw -Newman Jackson Bieberstein David Meyers -Huitt-Zollars Jeff Nigh -RTKL I have been reviewing the status of outstanding issues on Addison Circle in order to bring full closure
to the design phase and I find the following items still require some resolution: • I am unsure if final locations have been agreed upon for all transformers necessary to serve Phase
r. This will affect conduit placement by Gibson and is holding up the completion ofelectrical design for tree lighting. What is the status? (Action required by Columbus followed by approval
from Town) • Allowances for conduit and handholes necessary to provide power to each street tree are included in Gibson's contract however there is still no plan. Once all available
transformers have been identified, we can design the most cost-effi;ctive system. We will then provide Gibson with an accurate layout of the conduit system and we will prepare a separate
set of electrical plans (to be bid with the Bosque Park) for the wiring and receptacles. (HZ will act following resolution of transformer item, above) • The conduit layout for the public
street light system will require some minor modifications once T.U. Electric completes their design. Generally this will include specifYing the locations of hand holes and extending
conduit to specific transformer locations. T.U. should have a plan to us this week. (HZ will act within a week ofreceipt ofT.U.E. plan) • The final plat is still on hold pending resolution
ofreservation and/or license agreements. I believe all other plat comments have been satisfied. What is the status? (Action required by Columbus followed by approval by Town) • The plans
which were issued for construction reflected Peter Doctor's final design for tal1pole lighting of the roundabout. I want to point out that, on my instructions,. his design was based
on using pole styles and high pressure sodium lamps identical to those that C,IPROJ\O 199990 IIANDY'MEMOSlACPHl,PI Oaltas.1 Fort 'Norlh I Houston I Et Paso, Phoenix I Orange Coonw 
I Addison Circle Phase I Public Infrastrocture :MEMORANDUM Page 2 currently exist on the two streets that are affected. Thatis, lights on the Quorum approach lanes and around the roundabout are the square, brown, 30' poles with "shoebox" style fixtures. On the Mildred approach from the west, we re-used several
of the white goose-neck fixtures. We currently show one ofthese fixtures on the north side of Mildred but we may want to specify something less noticeable in this location. Any opinions?
(Action requested from all) • We are still wrestling with brick selections for streets and sidewalks. Since the roundabout will be paved this summer, we need resolution of this issue.
(Action required by Columbus followed by approval from Town) • Though it is actually a private development issue, we need a response from the MEP Engineer on the meters, vaults and backflow
prevention devices per the City's January 12th comments so we can properly coordinate the public work. We have been asking for this information since November 21, 1995. (Action required
by RTKL) Other than continuing to coordinate with private utilities, (which has now become a construction task rather than a design task) I am not aware of any other outstanding issues.

No. 01-2013-01 Dear Sir: Please find the enclosed concrete batch designs submitted to Huitt-Zollars on April 15th, 1996 for the above referenced project. We request that the mix designs
be revised and resubmitted for the reasons discussed below. Mix Design #8274 meets or exceeds the established requirements, however, the test results for specimens from Mix #K8274 appear
to be compressive test results for a 4,000 p.s.i. strength. We require the submission of test results for a 650 p.s.i. flexural strength per the plan requirements and as noted in your
report for Mix Design #8274. Mix Design #8272 meets or exceeds the established requirements and the specimen test results are acceptable. Mix Design #8272 can be approved as it currently
stands if submitted separately from the current Mix #8274 or with a revised and acceptable Mix #8274. In addition, please note that the wastewater manholes and stoimwater manholes require
a compressive strength of 3,600 p.s.i. and 4,200 p.s.i. respectively (See sheets 79 & 100 of 137.) We will require the submittal of a mix design for the manhole construction in addition
to the previous submittals. Sincerely, HUITT-ZOLLARS, 'INc. Engineering! Architecture SJ)lfi,uJ ·EfJl6-It:rJ David E. Meyers . I cc: John Baumgartner, P.E. Bryant Nail G:IJ'ROJ\O.20.30IIMP0422.lTR

214-$71-1.)757 May 14, 1996 Mr. John R Baumgartner, P.E. Director of Public Works Town of Addison 16801 Westgrove Drive P.O. Box 144 Addison, Texas 75001 RE: Addison Circle Phase I Selection
of Brick Pavers HZI Project No. 01-1822-04 Dear John: I have been working to resolve the issue of selecting an appropriate brick for use in Addison Circle, taking into account the Town's
concerns about serviceability and the developer's desires for a particular feel and appearance. In so doing I have reviewed the various test results versus ASTM specifications and the
recommendations that have been made by Sasaki Associates on the Town's behalf. I have also done some research into various brick-making techniques and spoken to several manufacturers,
distributors and the Brick Institute ofAmerica to try to understand what is important in making this decision. As a result, I have arrived at the following observations and conclusions.
The ASTM C902 specification was developed primarily in response to concerns about freeze-thaw durability of brick pavers. Its requirements for molded brick are not a modified or in any
way "relaxed" standard. The specification simply has two sets of parameters for two different but related products; molded brick and extruded brick. The level of perfonnance for any
"class" of application or "type" of environment is the same for both materials despite the fact that they may have measurably different compressive strengths and other characteristics.
That is, a molded brick (Class SX-Type 1) with a compressive strength of 4000 psi can be equal in perfonnance to an extruded brick of the same class and type but having a compressive
strength of 8000 psi because both meet the requirements of their respective parameters in the specification. The extruded brick (such as the Acme paver) is not better just becanse it
has a higher compressive strength. What is more important is the combination of characteristics of each material. Extruded bricks have higher compressive strength because they are more
dense. Molded bricks are lighter because they have larger voids. However, if a brick does not have a certain relationship between these parameters it may be subject to deterioration
due to freeze-thaw cycles. The very small voids in extruded brick can make them more susceptible to freeze damage than a properly balanced molded brick (i.e., one that meets the C902
limits for molded brick). In addition, if extruded bricks fail, it is generally due to layering that occurs in the extrusion process; a fault that is not present in molded brick. Therefore,
no purpose is served by holding a molded brick to the extruded brick limits. GoIPROJ\OII SZZ04\JB0506LTR Dallas f Fort Worth j Houston I EI Paso l?hoel 
Mr. John Baumgartner May 14, 1996 Page 2 If we were to try to compare a molded brick to an extruded brick, the only approach that I can suggest would be to compare how much each sample
exceeds the standards. I do not know if this is meaningful because the progression of individual limits may not be linear in their relationship to durability. However, the Glen-Gery
pavers can be compared with the Acme paver in this manner with the following results: % of Standard I Glen-Gery Acme Sidewalk Shillington Serendipity Yorkshire Paver Compressive Strength
(High) 153% 188% 213% 217% Cold Water Absorption (Low) 13% 14% 24% 13% Saturation Coefficient (Low) 58% 63% 69% 86% Abrasion Index (Low) 46% 42% 61% Not Reported The Glen-Gery "Shillington"
, "Yorkshire" and "Serendipity" pavers far exceed the requirements of ASTM C902-92 SX Type 1 and are therefore, in our opinion, suitable for consideration for use in the sidewalks at
Addison Circle. The Acme paver may be stronger and more durable than the Glen-Gery, however, there are many stronger, more durable pavers available that may not be the most appropriate
for this application. The Acme brick was originally proposed because it was the only brick we had identified at that time that met the standards. Even then, it was acknowledged that
its appearance was less than desirable in this application. According to the designers and the developer, the Glen-Gery paver suits the aesthetic goals of the district and, according
to the test results, it more than meets the specifications for the pedestrian and light vehicular areas. The selection of a paver for the streets is somewhat more problematic. An ASTM
standard has only existed for heavy vehicular paving bricks for less than two years. Prior to the introduction of ASTM C-1272-94, ASTM C902 was used for most public street projects (and
probably still is). Huitt-Zollars, Sasaki and many other consultants have specified C902 in applications identical to the proposed streets in Addison for years. The existence of the
new standard (coupled with the existence of lawyers) forces us to raise our standards but it does not invalidate the fact that there are scores of examples of brick pavement meeting
C902 that is performing well under conditions similar to those to be expected in Addison Circle. Because ASTM C1272 is relatively new, its applicability has not yet been fully clarified.
The specification states that it applies to areas with a "high volume of heavy vehicular traffic" and "such places as streets, commercial driveways and aircraft taxiways". While this
statement seems G,IPROJlOll S22()4IJBOS06.LTR 
Mr. John Baumgartner May 14, 1996 Page 3 simple enough, "high volume" and "heavy vehicular traffic" are not defined and there is a huge difference in the conditions to be experienced
by the Addison Circle streets and those of an aircraft taxiway. Further investigation reveals that ASTM C1272 is intended for volumes exceeding 1 to 1.5 million total cumulative Equivalent
Standard Axle Loads (ESAL). This equates to 30 to 45 eighteen-wheelers or twice as many buses per day based on a 20-year life. Even using a 50-year life it is unlikely that we will see
the resultant 12 to 18 trucks or 24 to 36 buses per day on a mews or residential street. On this basis, I believe we have imposed an excessively conservative specification for the street
brick and should, in fact, be using C902, not C1272 for the mews and residential streets. I am now convinced that the Glen-Gery Paver is suitable for these street applications for the
following reasons. • It comfortably exceeds the requirements of ASTM C902 for molded brick. • Durability and serviceability are more a function of the entire paver system than the individual
units. We have a very high quality system in the concrete base, asphalt setting bed and rigid edge restraints. • It has an abrasion index that is well below the limit for even CI272.
• This paver has been used successfully in drives and streets in Grand Rapids, Michigan and Columbus, Ohio, under their severe weather conditions. (See attached letter from Glen-Gery).
One drawback of this paver is that it is not lugged and must therefore be set more carefully so that an appropriate gap exists to brush sand in between the units. A lugged paver does
not require as much care from the installer and thus can be laid more quickly (and presumably less expensively for labor). Based on the projected traffic volumes for Mildred Street and
Quorum Drive (10,000 vpd and 30,000 vpd, respectively) and the corresponding estimates of heavy vehicular traffic (1 % to 2%), these streets would not fall under ASTM C902 and the more
stringent ASTM C1272 standard should apply. Though the Glen-Gery paver could prove to be suitable here as well, I have no technical basis for such a prediction and have no choice but
to recommend that another material be submitted that meets CI272. (Unless the developer wants to post an extended maintenance bond using the Glen-Gery paver). In conclusion, I feel strongly
that the Glen-Gery paver meets the letter and intent of our specifications for this project for use in the sidewalks and, now given a better understanding of the applicability of ASTM
CI272, I believe the Glen-Gery paver to be suitable for our mews and residential street applications as well. There is no question that more durable bricks (and other materials) exist
that could be used on this project. However, the same could be said for any material on almost any project. Durability is only one criterion for selection. We must also consider cost,
aesthetics and overall appropriateness for the project application. G:\PROJ\O 1182204\JB0506.LlR 
Mr. John Baumgartner May 14, 1996 Page 4 I will freely admit that I have reversed my own position on several aspects of this brick controversy but I have done so on the basis of further
research. I would be happy to meet with you and Sasaki to discuss this further. You may also feel more comfortable about the objectivity of my conclusions by talking to Mr. Brian Trimble.

12, 1996 Mr. John R. Baumgartner, P.E. Director of Public Works Town of Addison 16801 Westgrove Road Addison, TX 75001 RE: Addison Urban Center/Quorum Drive Stopping Sight Distance Study
HZI Project No. 01-1822-21 . Dear Mr. Baumgartner: In response to concerns about visibility over the DART rail line near the intersection of Quorum Drive and the proposed Mews M-3, Huitt-Zollars
has analyzed Quorum Drive's profile per standards established by the American Association of State Highway and Transportation Officials (AASHTO). AASHTO'S geometric design manual, A
Policy on Geometric Design of Highways and Streets, has been used as a reference for sight distances at different design speeds, object height, and driver's eye height. In Table ill-I,
pg. 138, the 1984 AASHTO manual establishes the driver's eye height as 3.5 feet above the the top of pavement, a minimum object height of six inches, and a maximum stopping sight distance
at a design speed of 40 miles per hour of 325 feet. The 40 mph design speed and its corresponding stopping sight distance of 325 feet were chosen to show that the Town of Addison's criteria
of a 30 mph design speed and 300 foot stopping sight distance would be met. The 1984 edition of the AASHTO manual was consulted first, and then these numbers were compared to those in
the 1994 edition, which uses metric units. When the metric units are converted to the English units used in the 1984 edition, it is evident that the driver'S eye height and object height
have not changed, nor has the stopping sight distance at 40 mph increased. We have used the proposed grades and stationing from the Arapaho Road realignment in conjunction with existing
plans and existing topographic shots on Quorum Drive to establish the top of pavement profile. Results of the study are shown on the attached plan and profile sheet for Quorum Drive.
Station 7+80 was identified as the critical point for visibility because it is on the far side of M-3 for a vehicle approaching from the south beyond the DART rail line. Using AASHTO
criteria, a driver 325 feet away must be able to see a six-inch high object at station 7+80. The top of the object at station 7+80 would be at an elevation of 626.38. A driver located
325 feet away would be at station 5+05 (note the station equation), and the driver's eye height would be at an elevation of 628.20. The profile shows that the line of sight between the
driver and the object 325 feet away is not obstructed by the crest in the road. Top of pavement and sight line elevations are noted on the profile where the graphical representation
of the sight Dallas I Fort Worth I Houston /8 Paso I Phoenix I Tustin I Ontario f San Clemente 
line and profile appear to converge. M-3's profile will be established in the design phase of Addison Circle Phase ITA with sufficient grades near Quorum Drive to ensure that objects
will be visible for a suitable distance east of the intersection. We plan to hold the grade on M-3 relatively flat for at least 30 to 40 feet east of Quorum and then transition down
to existing grade. Please call if you have any questions. Sincerely, DMlbdb Attachment cc: Bryant Nail g:\proj\O1182221Isigh..,d.tx'

joints. This material is being questioned as an appropriate application for the Witt Mews centerline joint which was mistakenly sawed by the contractor. Huill-Zollacs has investigated
some possible alternatives for Ihe Witt Mews centerline joint in an .attempt 10 satisfy the Columbus requirements for aesthetics and the Town of Addison's concern with maintenance. ALTERNATE
NO. I Require Gibson & Associates to submit a high grade silicone joint material and application procedures for the joilll in quesliun. The silicone joint sealant is gray in color al
Ihe lime of application which 􀁡􀁤􀁤􀁲􀁥􀁾􀁾􀁥􀁾􀀠short term aesthetic issues. However, over time the joint sealant will be blackened from tire marks, dirt and fluids washed down the
alley. We recommcnd that the Town request an extended maintenance warranty for the joint material and installation which will address the maintenance issue. Long term maintenance will
be required as is the 􀁣􀁡􀁾􀁥􀀠for all joints. ALTERNATE NO.2 Require Gibson & Associates to install a 􀁄􀁥􀁬􀁡􀁾􀁌􀁩􀁣􀀠Preformed Neoprene Compre5SioD Seal manufaclured by the f).S.
Brown Company. Neoprene seals exert a compressive force on the joint to actively prevent the entry of moisture inlo the joint. We would require the use of Pavcmcnt Seal 11437 to be applied
with DELASTALL NO. 104 AUlo-IIL_talll" with the lubricants specified by Ihe manufacturer. Neoprene Compression Seals have an extended performance life of 15 to 20 yean;. The company
has no warmnty plan for the material. We would again suggest hat the 'rown require an extended maintenance warranlY from Gibson for this material and installation. The disadvantage of
this joint is nut being availahle in any cIllor other than black, which is a major concern to the developnlen! from an aeslhetic point of view. G:\PROMI201301\BNOMO.l.TR IJIJI18'11 FOfl

No. 01-1932-01 Dear John: We are transmitting herewith for your approval five signed and sealed sets of construction plans for the Addison Circle Apartments -Phase I private development
which address your review comments dated January 3, 1996. Your comments are listed below in italics and the action we have taken is noted. General: 1. Provide plans prepared by a Texas
Registered Professional Engineer. Done. 2. Plat: A. Provide for separate instrument dedication of easement on property owned by others. Submit formal request for easement on property
owned by the Town of Addison. Separate exhibits and legal descriptions for a drainage easement and a T.U. Electric easement on Town owned property are currently being prepared by a Texas
Licensed Professional Surveyor and will be submitted to you for approval upon their completion. B. Clearly provide for easement dedications on this plat. We have added "by this plat"
to the description of all of the easements to be dedicated by the filing of the plat. We have also deleted the temporary construction easement on the water tower site per your phone
conversation with David Meyers on 118/96.L G,IPROl\OIl93201\1BOIlLLTR Dallas I Fort Worth I Houston I E1 Paso I Piloenix I Orange County 
Mr. John Baumgartner January 11, 1996 Page 2 C. Provide the street, lane, road identifier for Witt Mews and Paschal Mews. Mews is the identifier. D. Dedicatory language requires the
review of the City Attorney's office. Acknowledged. Per your phone conversation with David Meyers on 118/96 the plat submittal will be reviewed by the City Attorney's office and a separate
submittal by Huitt-Zollars will not be required. E. Provide survey prepared by a Texas Licensed Professional Surveyor. The plat submitted was prepared by a Texas Licensed Professional
Surveyor in the State of Texas. The plat is currently being revised and will be signed and sealed by the surveyor when it is submitted in a few days. The plat will also be stamped preliminary.
When the plat is ready to be filed, the preliminary stamp will be removed and all of the necessary signatures and seals for filing will be added to the plat. F. Provide dimensional ties
across the public roadway in and adjacent to the plat. Done. G. Coordinate additional easements required in conjunction with the public infrastructure plans reviewed on 12/28/95. Contact
Ken Roberts with Huitt-Zollars for specific locations. Done. 3. Drainage Plans: A. A license agreement is necessary for all private improvements that encroach into the public right-of-way.
A license agreement is being prepared by and between the Town Attorney's office and Mike McWilliams who represents Columbus Realty Trust in this matter. B. The location of the drainage
system located on Conference Centre property has not been approved by Council. A formal easement request is required. We have revised the easement per your requests to minimize the encumbrance
on the Town's property. The easement request will be made when the exhibits and legal descriptions are complete. G:\PROJ\01193201\JBOII I.LTR 
Mr. John Baumgartner January 11, 1996 Page 3 C. For private drainage improvements proposed to be located on public property provide the following typical details: 1. Typical trench showing
the specific PVC product proposed, pipe bedding, backfill material, and performance testing, Ie: mandrel test, air tests required. We have added the Town's typical trench detail for
the installation of SDR35 sewer pipe to be used in the Mew's streets only. Testing will be in accordance with NCTCOG requirements found in Part ill-Construction Methods, Division 6 -Underground
Conduit Construction, Item 6.7.2 Sanitary Sewer. 2. Provide cleanout detail for roadway/sidewalk installation and detail/notes on how this is accomplished in conjunction with the public
infrastructure installation. (perhaps manholes on +/-300 foot centers would be a better application.) We have added the Town's cleanout detail to the plans and added a note about coordination
between the private and public contractor. 3. Provide connection details. All connections to the PVC drains will be made with factory wyes and bends. A detail has been added to the drainage
plans for the buildings. D. Provide material cut sheet for pipe with manufacturer's recommendation for use in this application, ie: sanitary sewer product used as for stormwater runoff.
PVC sewer pipe should be more than adequate for the private stormwater drains based upon information found in three manufacturer's brochures for PVC sewer pipe. Brochures from Diamond
Plastics Corporation, CertainTeed Corporation, and Contech Construction Products describe PVC pipe as follows: 1. "PVC pipe is tough, economical, resilient, and corrosion resistant both
inside and out. It's ideal for just about any underground pipe application or any fluid transfer system. And once it's in the ground, You can forget about it, becausc the joint has the
strength and built-in flexibility to 'give' with underground shifts and surface shock loads without cracking or breaking the watertight seal." G:\PROMI19320lUBOI I l.LTR 
Mr. John Baumgartner January II, 1996 Page 4 2. "PVC sewer piping systems meet the needs for low installed cost and minimum operating eosts because it offers light weight, long lengths,
smooth and uniform interior with a low Manning Factor of n = 0.0009 for PVC, and tight all-weather FLUID-TITE single gasketedjointed system." 3. "PVC provides excellent durability and
resistance to abrasion and scouring, as well as eorrosive attack from both acidic and alkaline soils. More importantly, PVC has proven itself in the trenches in a variety of applications
for sanitary sewers, storm sewers, and subdrainage systems." E. Show dimensional offset to the property line. Recommend a minimum 3.0 foot setback where possible. We have added typical
sections showing the reeommended locations of the private building drains and have also provided for the flexibility to change the horizontal location on private property to avoid conflicts
during construction. F. From the typical section proposed, there appears to be a conflict with proposed utilities. Illustrate on the plans, and in a cross section where the proposed
storm sewer is going in relation to the other utilities and improvements for the mews streets. A typical section has been added which demonstrates no conflict with other utilities in
the streets and mews. Please feel free to call if you have any questions. Sincerely, HUITT-ZOLLARS, INC. Engineering! Architecture Associate -cc: Bryant Nail G:\PROJ\Ol193201\JB011 LLTR

15, 1996 Mr. John R Baumgartner, P.E. Director of Public Works Town of Addison P.O. Box 144 Addison, Texas 75001 RE: Addison Circle Public Infrastructure Response to Letter Dated December
26, 1995 H-Z Project No. 01-1822-04 Dear John: With respect to the items in your December 26th letter, I would like to respond in letter form rather than issuing separate design reports
for these relatively minor items. A. Bricks Bricks have been used in streets and sidewalks successfully for centuries and are used without undue concern or incident by most municipalities
in this area. There is no engineering justification for their use. They are simply an attractive alternative to concrete pavement. It is, however, important to choose the right kind
of brick for each application and to install them properly. The bricks selected for use in the sidewalk areas of the Addison Circle project conform to the ASTM C902 standard for light
vehicular loading as evidenced by the test results we have previously submitted to you. (Copy enclosed) They are to be set on a concrete base equal to your standard sidewalk and are
sufficiently regular to fit snugly together in the patterns we have indicated with the edge restraints specified. They will not be perfectly uniform and there will be some variation
in the walking surface. However, it will be much more uniform than Uptown Village and roughly equivalent in texture to the effect created by many of the concrete pavestone patterns that
are commonly used in sidewalks. Certain limited vehicular areas will receive brick accents (crosswalks and patterns in mews and roundabout) to be placed on a concrete base equal to your
standard pavement requirements. These bricks will be set on a layer of asphalt with a tack coat for adhesion. The bricks will have a lug on the side to create a joint to allow cement
stabilized sand to be swept between them and to keep the pointed comers of the brick from chipping when traffic loading pushes them together. Bricks installed in this manner have performed
in State-Thomas for over five years without any maintenance. We do not yet have test information for a heavy vehicular rated brick similar in G:IPROlIOI182204IJB 122S.LTR Dallas I Fort
Worth I Houston I El Paso I Phoenix I Ofange Counly 
Mr. John Baumgartner January 15, 1996 Page 2 appearance to the "Old Virginia" sidewalk brick to be used on this project. However, the "Acme" lugged brick used in State-Thomas is available
and meets the specifications for heavy vehicular loading ifno other product can be found. The bricks specified for this project are dense, hard fired products that should not be adversely
affected by contact with stormwater or irrigation runoff. The few areas in the mews streets where bricks are indicated in the invert ofthe street (and the gutterline crossing the mews
at the intersecting streets) should be of no particular concern. As long as the concrete base is intact, the entire pavement section, including the brick, will be serviceable. The joints
in the invert and gutterline are just as likely to collect dirt due to their location as they are to have their joint material washed out. The dimensions and uniformity ofthe bricks
will hold them in place and their materials properties will keep them whole. The presence of runoff on the brick, as with any surface, will adversely affect its skid resistance. However,
nuisance flows will be confined to the gutter and the mews centerline invert, neither of which are in the normal path ofa vehicle's wheels. When crossing these flow areas, vehicular
speeds will be extremely slow due to the confmed space. If sufficient runoff is present to expand into the driving path, it is most likely that all of the pavement will be wet and motorists
VI:ill respond accordingly. In summary, if the brick pavement is installed as detailed in our plans and specifications, it will provide a safe, serviceable pedestrian and vehicular surface
that is as durable as any surface the Town of Addison is currently using for streets and sidewalks. I am enclosing several technical publications on the use of bricks in pavement for
your reference. B. Curbless StreetlMews Intersection The current version ofthe intersection ofmews streets with other streets employs a curbed radius into the mews. Due to the street
profile, this curb, as a vertical element, disappears in the barrier-free ramp and is only a horizontal band as it continues into the mews to the tangent point. The introduction ofthis
curb and banding element as well as the ramp with its detectable surface are, we believe, sufficient warning to pedestrians ofa change in the sidewalk condition. Conflicts between vehicles
and pedestrians are an accepted element of true urban living. Just as in any other environment, they both adapt their behavior to fit the prevailing conditions. Vehicles move more slowly.
They creep carefully out ofgarages and alleys where sidewalks cross. Pedestrians look before crossing such entrances and they function without incident every day with far less physical
warning and sight distance than we have provided at Addison Circle. Signage will be placed outside ofthe travel lanes, in some cases behind the curb. There is no more reason to believe
these signs· are at risk than are the signs at any intersection, G:\PROJ\01182204UB1228.L TR 
Mr. John Baumgartner January IS, 1996 Page 3 especially those with depressed curbs and barrier-free ramps. Actually, because we have a 30 foot radius at these intersections, I believe
the signs will be less likely to be hit than most other locations. We therefore have no reservations about the safety or operation of these intersections as designed. C. Mid-block Crosswalks
on Quorum Drive Though we have checked the sight distance in the field and found it to be more than adequate, we have deJeted the crosswalk at the railroad based on input from Bryant
Nail and Carmen Moran. The crosswalks at sta. 20+51 are at the intersection of Quorum Drive and McKamy Avenue and are not, in our opinion, mid-block crossings even though there is no
median opening or continuation of McKamy east of Quorum. In a highly urbanized pedestrian environment, frequent street crossings are essential. The small-block concept of Addison Circle
reflects this premise. Once the project is built out, people will be crossing Quorum Drive frequently. If we don't put crosswalks on the extension of approaching sidewalks, people will
cross there anyway. The crosswalks provide a warning to the driver and a safer situation for the pedestrians. These crosswalks could be delayed until Phase II (and might be if dictated
by budget) but we would like to build them now while traffic is lighter and we are removing pavement in the vicinity anyway. If, in the future, conditions warrant it, pedestrian crossing
signals could be introduced. In summary, we have no reservations about the appropriateness of this crosswalk as designed. Sincerely, HUITT-ZOLLARS, INC. Engineering! Architecture Andrew

Texas 75001 RE: Final Plat! Addison Circle Phase I HZI Project No. 01-1932-01 Dear Ms. Moran: I have received the staff report dated January 18, 1996 which recommends that the referenced
plat be tabled pending resolution ofthe three items on Mr. John Baumgartner's memo to you of the same date. Those items are noted below, followed by our response and/or proposed action.
1. The geometries for the roundabout at Mildred and Quorum are subject to the final design. This may necessitate an enlargement ofthe right-of-way provided. Given the criteria for the
design ofthe modem roundabout which were imposed on us by the Town of Addison (e.g., the traffic volumes to be expected on Mildred and Quorum), there are no circumstances under which
additional right-of-way will be needed for the roundabout (A separate response covering all roundabout issues is forthcoming). 2. Add the following note to sheet one: The use ofthe "private
utility easements" shown on this plat are subject to the terms and conditions set forth in the street license/rental agreement between the Town ofAddison recorded in DCDR Vol. Pg. .
This note will be been added to the plat as requested, however, my draft of that document does not refer to it as a "street license/rental agreement". 3. VerifY that the easements necessary
for franchised and licensed utilities (Southwestern Bell, TV Electric, Lone Star Gas, Herron Cable. TCI Cable, etc.) are provided. To date we have contacted every utility provider at
least twice and asked them to identify for us what they will require (see attached letters). We have had no meaningful responses from any of the possible service providers except T.U.
Electric. However, the following summarizes our understanding of their probable needs. G:\f'ROMI193201\CMOi 18.LTR Dallas I Fort Wonh I Houmon I 1,;1 Paso I Phoemll: I Orange CO\Jlity

Ms. Carmen Moran January 18, 1996 Page 2 TCI & Herron Cable: There will be no need for these facilities in Columbus's projects and therefore no need for easements in Phase I. Southwestern
Bell Telephone: Telephone trunk lines will run in the public right-of-way as needed throughout tile district. Columbus's project will have a private telephone system which will be fed
by SWBT to a single point in Building A. Equipment will be inside the building, therefore, no easements should be required. Lone Star Gas: Gas mains will be run in the public right-of-way
as needed throughout the district to provide for service to various facilities. Phase I currently indicates a single gas meter near the northeast comer of Building A. Normally Lone Star
Gas does not require easements for individual service lines of this length. If one proves to be necessary, it can be documented by separate instrument. T.U. Electric The easements requested
by T.U.E. are shown on the plat. Pending the outcome of fmal electrical design for street lighting, additional easement area may be needed for additional transformers. These can be handled
by separate instrument or an amended plat (replat). I have asked on several occasions what constitutes a "sign-off' by the public utilities. I cannot obtain it until I know what is expected.
It is my belief that these three items can be adequately dealt with prior to the Planning and Zoning Commission meeting ofJanuary 25th, however, I will confirm the status of the plat
prior to the meeting. Sincerely, HUITT-ZOLLARS, INC. Engineering! Architecture Andrew C. Oakley, P.E. Senior Vice President ACO/psp cc: John Baumgartner Bryant Nail O:\PROJ\OI193201\C'.\10118.LTR

John: I am in receipt of the memo from Nancy Armstrong of Sasaki, Associates which indicates that the specified pedestrian brick does not meet ASTM C902. Referring to the copy ofC902·92
attached to the memo, I direct your attention to paragraph 4.8 Molded Brick, as follows: 4.8 Molded Brick (Soft Mud, Semi-Dry Pressed, and Dry Pressed Brick) -The requirements listed
in Table I shall be changedfor molded brick to permit maximum absorption of I 6% average and 18% individual, and minimum compressive slrengths of4000 psi (27.6 MPa) average and 3500
PSi (24. I MPa) individual for Class sx, provided that the requirements for saturation coefficient coefficient of Table I are met. The proposed Old Virginia brick is a wood molded product
that meets these requirements based on the independent test results supplied to you. While its average saturation coefficient of 0.71 is near the maximum of 0.80, its performance under
all other criteria is significantly better than the specified limits. It is not necessary for a product to significantly exceed all standards in a specification for it to perform adequately.
The fact tbat it is within the parameters should be sufficient. Unless I am misinterpreting either the standard or the test results, this product is within the established parameters.
If the Town chooses to impose a stricter standard or simply does not reel comfortable with this product, that is your prerogative which will most likely be reflected in a higher cost
for the project. Sincerely, HUITT-ZOLLARS, INC. Engineering! Architecture ley, P.E. esiden! ACO/psp cc: Nancy Armstrong Bryant Nail Dallas I For! Worth i Houstoo I tEl Paso I Phoenix

received on January 31, 1996 at 4;00 p.m. for the Addison Circle phase I Public Inftastruoture proje<;t. With this letter we are returning to you the originol bids ond the bid tabulation.
The thtee low base bids were received Ii"om Gibson &. Associates for 53,425,3 51.64; Reb.:on Inc. for $3,684, 152.28; and ArchitecturalUtilities, Inc. for 53,946,508.11 and Were cOlTectly
ca!<:ulatedexceptfor &$0.25 error on the bid from Architectural Utilities. The three low bidders bave done quality work around the DFW Metroplex for several yeMS and anyone of them would
be acceptable for this project. The apparent lowest bid is approximately S60.000 below our curren! cost estimate. As we noted when initially reviewing the bids, Gibson and Associates
had manually changed their bid total to increase it by $40,000 (which is reflected in lit. $3,42S,357.64). This addition.1 $4O,OOQ was made in a lump sum line item on l!!l! of the two
required copies of the bid that was submitted. Since they clearly intended to increase that item on both copies and did properly increase the subtotals and totals, we believe the higher
price for the item ,hould be accepted. Huitt-Zollars, therefore, recommends thllt the Town of Addison award the contract for the constnlclion of Addison Circle Phase I Public Inliasuucture
to the low bidder, Gibson & Associates. The awan! should be based on Schedule, 1 through VllI only (th. Sase Bid plus the Ph..e II Alternate Stre<:lscape Improvements) which (otel 53,4fiS,655.24.
The contIaclorshould be notified howevelthat certain items in Schedule IX Illay be added by change order if funding beoomes avail.ble. Please note also that the streetlight. and th.ir
ba= which _ in Schedule IX must be constructed but not necessarily by this COlItractor. 'Ih<refore an allowance in the overall budget should be held out for these items. In the evtll[
that the contract is not awarded to Gibson &; ASSQciates. Huitt-Zollars recommends that the next lowest bidder, Rebeo", Inc., be awarded the canlr_ct. Please give me a call if you should
have any questions. Sincerely, HUITT-ZOLLARS, INC Engineering,lArcbilecrure 􀁴􀀺􀀬􀀮􀀮􀀬􀁤􀀮􀁤􀁾􀀠Kenneth A. Roberts, P.E. ! Associate I I !John Baumgartner,P.E.· Town of Addison, DirettofofPublic
