Required Proposal content All proposals must contain the following information: Firm Name Year Established Business Address and Telephone Number Present ActivityEstimated Annual Capacity Banking Reference Complete description of design approach steps and proceduresA Schedule outlining the major steps taking into consideration that the Town considers this a project where time is of the essence References demonstrating experience in projects of similar scope Identification of consulting staff assigned to the project, along with profiles of their background and experience A description of corporate (team) qualifications and relevant experience of the firm(s) Signature with date of submission IV. Proposal Evaluation Criteria The Town of Addison desires to employ a firm with an established track record of successful completion of architectural/engineering projects with a similar scope. Proposal will be evaluated on: The breadth and depth of the firm's experience of completing projects of similar scope, especially in the North Dallas area The specific experience of the proposed members of the project team The stability and resources of the firm(s) The satisfaction of recent clients The qual i ty and responsiveness of the proposal Request for ProposalJune 22, 1992 Page 3 V. Consultant Selection Process Proposals will be evaluated by a committee. A limited number (2-3) firms may be requested to make oral presentations to the committee. One firm will then be recommended for final contract to the City Council. The Town of Addison reserves the right to reject any and all proposals should it be deemed in its best interest. June 22, 1992 Mr. Randall Bauer MPI Architects 16479 Dallas Parkway, suite 490 Dallas, Texas 75248 Dear Mr. Bauer: I enjoyed speaking with you on Thursday. The Town of Addison is considering building a walkway over the Dallas North Tollway. It could, in fact, be a combination walkway/small motorized vehicle way. This would tie the Quorum Office Park to the Village on the Parkway. I have attached a request for proposal if you are interested in this project. We will be making requests of at least two other firms and will select an architect from that group. If the City Council grants approval of this project in late July, 1992, it would move rather rapidly. We would appreciate your submittal as soon as possible. If you have any questions, please give me a call at 450-7028.

The following four pages illustrate decision points for pedestrians on a generalized map of the intersection. As is the case with today's crosswalks, a bridgeuser must decide his corner destination before crossing. The tunnel user can postpone his decision until arriving at the rotunda under the center of the intersection. One consequenceof this difference, for example, is that a pedestrian on the west side of the Strip would cross halfway to the east side on a northbound trip with the tunnel alternative. 7 How these differences might affect a user's choice of destination is subjective and is left to the individual reader.

BurgessBridge Alternative -Phase 4 Handout for 3rd Round of Las Vegas Boulevard/Flamingo Road Property Owner's Meetings Pedestrian Grade Separation Project The tunnel option crosses the Intersection diagonally and has a 60-foot diameter center room. The finished cross-section will have a curved roof and will be approximately 12 feet high and 24 feet wide. The preliminary assessment of the subsurface conditions Indicate that tunneling is possible. The general soil conditions consist of fill overlying dense to very dense sands, gravels, and clays, to a depth of approximately 5.0 to 7.5 feet. Below this level the soil profile generally consists of a heavily-cemented sands and gravels layer, interfingered with the dense to very dense sands and gravers. Based on the four just-completed test borings, it is anticipated that at least five feet of cemented sands and gravels will be above the tunnel in all locations. The groundwater depth ranges from about 11 to 13 feet below the ground surface. These conditions present a medium which is good for tunneling since heavily-cemented materials overhead provide a bridging layer for 􀁴􀁾􀁥􀀠excavation below it. The proposed tunnel construction wi!! start with dewatering the entire site prior to construction to draw the water down below the proposed invert elevation of the tunnel cross-section. This will occur for several months prior to initiating construction of the shafts. Shafts (or vertical access wellsl will be constructed at three of the corners but will not be constructed at the northeast corner. The primary construction shaft will be located at the southwest corner. Construction within the street right-of-way will consist primarily of caisson drilling and pouring. Bridge beams will be placed over the caissons such that tunneling activities have minimum impact on traffic. Tunnel construction will begin at the southwest corner and proceed to the northeast tunnel. Then tunnels will be constructed to both the southeast and the northwest corners. The center room, which is approximately a 60-foot diameter room, will be constructed after all tunnel construction is complete. The methods of tunnel construction will be either hand-mining or mechanical excavation using equipment such as roadheaders or backhoes to excavate the face. The final crosssection will be water tight, clean, and provide an open high-and-wide cross-section ready for finishing and equipment installation. . The estimated time for construction of the tunnel alternatives, after initial dewatering and utility relocations, is approximately 13 months. The duration of the construction impact to casino properties located on the northeast, northwest, and southwest corner shOUld be one to two months maximum. The duration of project-related activity on the Bellagio property on the southwest corner will be approximately 16 months.

Bridges are 95% visible from surface; heights to 35 feet above ground. • No out-of-direction travel for most pedestrians; shorter walking distances. • Half as many escalators 18) and half as many elevators 14) as bridges; reduces maintenance and electrical power costs. Equipment has less exposure to elements. However, each escalator is longer and more expensive. • Easier security monitoring Ifrom center all tunnels can be monitored); may reduce vandalism costs. Tunnel Cons • Construction disruption at corners. • No redundancy in case of tunnel blockage (one of four bridges could be out of service and not require surface crossing). • Risk of something new and different; not proven in the sense that Tropicana bridges are proven. • 30% more vertical travel for users 130 feet versus 23 feet). • Requires ventilation and lighting. • Does not offer the viewing opportunities of bridges. 􀁃􀀧􀁾􀀠Carter.BurgessTunnel Versus Bridge
