\ \ J and make recovery more difficult than just changing components. Each ofthese components is to be provided in the manufactures original packaging. This change is reflected in the revised electrical drawings dated 3-23-05. 5) Reolace metal grating steps with concrete step Replace the 10 metal grating steps in the secondary containment area with a 9" high concrete step. 6) Replace norescent light imurcs with 250 watt metal halide lights Replace the florescent light fixtures with low base 250-watt metal halide in two rows on each side ofthe facility. The low base fixtures cover more area with higher lumens; so rewer fixtures are needed for the same light level. This change is reflected in the revised electrical drawings dated 3-23-05. 7) Fire protection coating ofthe canopy rafters Do not fire protect coat the shape metal rafters ofthe canopy structure. A technical review has been perfonned on the canopy structure perfonnance and the conclusion is that since the proposed shaped rafters are not under load and will be supported in a fire by the rated coated colunms ofeach bent, there is no reason to coat the rafters. 8) Use horizontal filter/separators Use ofhorizontal filter/separators for this system is acceptable providing you can install them appropriately in the system within the space limitations ofthe secondary containment area and maintain access for filter changes. The draft tank layout shop drawing indicates the horizontal filter/separator will fit in this layout. 9) Use of aluminum case mechanical now meters Use ofaluminum case mechanical flow meters versus double case steel meters is acceptable based on this application. Systems using two or more large volume storage tanks that would pass all fuel through one or two lines would have a much higher utilization rate and would warrant a double steel case meter. This system dispenses through 14 separate tanks and no single meter will have high volume utilization. 10) Eliminate canopy gutters, downsoouts and associated underground piping Eliminate the canopy canopy gutters, downspouts, sidewalk connections and underground PVC drain lines (E & D) and catch basin on the south end ofthe oil/water separator. Connect the separator outfall line directly to the existing stonn sewer system by transitioning to 10" RCP line. 11) Use the Blackmer XL3B 200 gpm pump Pending verification by the manufacturer for this application, use the Blackmer XL3B 200 gpm aviation fuel pump for the AvGas tank and dispensing system. 12) Modify the 10' & 6' vinyl covered fence structure detail Change the 10' fence detail to 8' high with posts set at 7' on center instead of 10' and with top rail and bottom guy wire. The 8' rence remains black vinyl covered chainlink rence fabric with black slats. Change the post setting for the 6' black vinyl covered chain-link fence fabric with black slats and barbwire to 8' on center instead of 10', with top rail and bottom guy wire. Other chain link fencing remains as per plans except add top rail and bottom guy wire. Shop drawings from the subcontractor will be reviewed and the additional cost must be determined.

Install the catwalk only over each ofthe FBO tanks with separate ladder at each FBO. The transverse walkway and catwalk will be attached directly to the tank and the catwalk will span the tanks in each FBO area with a separate ladder to the floor ofthe containment. Attachment pads are to be welded to the tanks by the tank manufacturer and the walkway stanchions attached to the pads by bolting or welding in the field. Shop drawings on the catwalk structure, details and attachments have been provided. 2) Use one mechanical flow meter with electronic remote displays. Install one mechanical flow meter at the pump and use remote displays to indicate pumped fuel quantity at the dispense and off-load stations. The dispense display must still allow stage down of flow through the "Cia Valve" or similar for filling Jet A airport refue1ers. The cost reduction is the di:ffurence between the cost of the 2nd meter at each tank unit and the electronic display installation. This change is reflected in the revised mechanical and electrical drawings dated 3-23-05. 3) Eliminate concrete encasement ofconduit (duct bank) ODder slab. Do not encase the electric cable duct bank under the secondary containment structure. Only the duct bank from the transformer pad to the containment slab needs encasement, along with ducts from the power pole drop and from the transformer to the MCC. The conduits must be spaced and bedded in suitable backfill. 4) Eliminate redODdant control ODils in system control panel. Eliminate the redundant complete PLC on the tank overflow monitoring system and provide a spare CPU and at least one ofeach IIO cards to serve as a backup control unit ifthe PLC were to faiL Since the system is designed to fail closed (or oft), one preprogrammed CPU, a spare power supply and a spare ofone of each type ofIlO cards used in the system will provide sufficient backup and immediate response in case offitilure, and reduce the adverse impact to the system from a lighting strike in the area which could eliminate the programming on both systems GWashington Lundgren. 303·843·3596 and make recovery more difficult that just changing components. Each ofthese components is to be provided in the manufactures original packaging. This change is reflected in the revised electrical drawings dated 3-23-05. 5) Replace metal grating steps with concrete step. Replace the 10 metal grating steps in the secondary containment area with a 9" high concrete step. 6) Replace florescent light fixtures with 250 watt metal halide lights. Replace the florescent light fixtures with low base 25O-watt metal halide in two rows on each side ofthe facility. The low base fixtures cover more area with higher hnnens; so fewer fixtures are needed for the same light level. This change is reflected in the revised electrical drawings dated 3-23-05. 7) Fire protection coating of the canopy rafters Do not fire protect coat the shape metal rafters ofthe canopy structure. A technical review has been performed on the canopy structure performance and the conclusion is that since the proposed shaped rafters are not under load and will be supported in a fire by the rated coated colunms of each bent, there is no reason to coat the rafters. 8) Use horizol1tal fdterlseparators Use ofhorizontal filter/separators for this system is acceptable providing you can install them appropriately in the system within the space limitations ofthe secondary containment area and maintain access for filter changes. The draft tank layout shop drawing indicates the horizontal filter/separator will fit in this layout. 9) Use of aluminum case mechanical flow meters Use ofaluminum case mechanical flow meters versns double case steel meters is acceptable based on this application. Systems using two or more large volume storage tanks that would pass all fuel through one or two lines would have a much higher utilization rate and would warrant a double steel case meter. This system dispenses through 14 separate tanks and no single meter will have high volume utilization. 10) Eliminate canopy gutters, dowl1spouts and associated Ul1dergroUl1d piping Eliminate the canopy gutters, downspouts, sidewalk connections and nndergronnd PVC drain lines (E & D) and catch basin on the south end ofthe oil/water separator. Connect the separator outfiilliine directly to the existing storm sewer system by transitioning to 10" RCP line. II) Use the Blackmer Xl.5B 150 gpm pump Pending verification by the manufacturer for this application, use the Blackmer X2.5B 150 gpm aviation fuel pump for the AvGas tank and dispensing system. 12) Modify the 10' & 6' vinyl covered fence structure detail Change the 10' fence detail to 8' high with posts set at 7' on center instead of 10' and with top rail and bottom guy wire. The 8' fence remains black vinyl covered chain-link fence fabric with black slats. Change the post setting for the 6' black vinyl covered chain-link fence fabric with black slats and barbwire to 8' on center instead of 10'. Other chain link fencing remains as per plans. Shop drawings from the subcontractor will be reviewed and the additional cost must be determined. " Washington Lundgren. 303-843-35% 13) Thicken the concrete pavementor structure floor 1 " Instead ofthe 12" hydrated lime stabilized subgmde, the concrete structure and pavement may be increased in thickness by In. Subgrade must be compacted per specifications and the aggregate base course (ABC) thickness and compaction requirements remain the same. (per verbal direction by ECS) 14) Add a relaxation chamber to Jet A system Addendum #2 directed deletion of the relaxation chamber from the Jet A system; however, the revised drawings and specifications indicate a ISO gallon relaxation chamber is required. After verification by Burns & McDonnell, shop drawings from the subcontractor will be reviewed and the additional cost must be determined. IS) Delete Butterfly Valves Delete the butterfly valves shown in front (upstream) ofthe horizontal filter separator and in front (upstream) ofthe ISO-gallon relaxation chamber Remaining Items to address for start of construction: 1.

END OF DOCUMENT Page 1 of 1 Mark Acevedo From: rnormandeau@thielsch.com Sent: Monday, March 28, 2005 7:13 AM To: Mark Acevedo Cc: samueLiundgren@wginl.com; PKennefick@thielsch.com; TLent@Thielsch.com; neil.rood@wginl.comd Subject: Notice to Proceed 3/28/05 Mark, I received a lot of drawing and specification information on Friday afternoon from Sam. It took a while to review it and understand what was included. After better understanding the information, I don't agree that the pre-construction items are complete and request the notice to proceed not be issued yet. One example is with regard to the horizontal filter/separators. The change order states " ...providing you can install them appropriately in the system and 􀁷􀁩􀁾􀁨􀁩􀁮􀀠the space limitations of the secondary containment area and ..." I expected from the value engineering and pre-construction meetings that they were approved by engineering and would be shown on the drawing instead of the vertical filter/separator. I expected the necessary pipe routing changes would also be included. The other question is the cost and who pays for them. There may still be hope that they can be excluded from the design without compromising system performance or safety. On the draft change order, it was initially indicated that the additional cost to strengthen the fence was to be taken from the construction credits from the Feb. 11, 2005. I didn't agree. Now it says the additional cost must be determined. Cost is a significant issue that must be resolved before we start work in the field. There are only a few other technical issues that Sam and I have been working closely on and we're both willing to continue to do so. We are close to resolving them, but I think we need to get the engineering, construction, and Town of Addison decision makers on a conference call, or in the same room, assign action items, due dates, and resolve them. If we all work together, we can finalize where we need to be to get started on the right foot. I believe it's possible that these issues can be resolved in a short time and be able to start construction very soon.

Respectfully submitted, Samuel G. Lundgren, P.E. Project Engineer Washington Group International, Inc. I Attachment: Construction Change Order, dated Mar 25, 2005 oWashington Lundgren, 303-843-3596 􀁊􀁲􀁉􀁊􀁾􀀡􀀮􀀷􀁬􀁾􀁁􀁩􀁲􀁰􀁯􀁲􀁴Date: March 25, 2005 Subject: Construction Constructive Credit Change Order for the Bulk Fuel Storage and Dispensing System, Addison Airport To: Thielsch Engineering, Inc. 2111 Dickson Dr. Suite 10 Austin, TX 78704 Attn: Mr. Rick Normandeau Mr. Normandeau, You are hereby ordered to make the following changes in the plans and lor specifications for the above-designated project as constructive credit against the current contract amount, which is summarized at the end of this document. 1) Modify the catwalk to be supported from the tanks. Install the catwalk only over each of the FBO tanks with separate ladder at each FBO. The transverse walkway and catwalk will be attached directly to the tank and the catwalk will span the tanks in each FBO area with a separate ladder to the floor ofthe containment. Attachment pads are to be welded to the tanks by the tank manufacturer and the walkway stanchions attached to the pads by bolting or welding in the field. Shop drawings on the catwalk structure, details and attachments have been provided. This change results in $15,600.00 of constructive credit for the contract. 2) Use one mechanical flow meter with electronic remote displays. Install one mechanical flow meter at the pump and use remote displays to indicate pumped fuel quantity at the dispense and off-load stations. The dispense display must still allow stage down of flow through the "CiaValve" or similar for filling Jet A airport refuelers. The cost reduction is the difference between the cost of the 2nd meter at each tank unit and the electronic display installation. This change is reflected in the revised mechanical and electrical drawings dated 3-23-05, and results in $50,400.00 ofconstructive credit for the contract. 3) Eliminate concrete encasement of conduit (duct bank) under slab. Do not encase the electric cable duct bank under the secondary containment structure. Only the duct bank from the transformer pad to the containment slab needs encasement, along with ducts from the power pole drop and from the transformer to the MCC. The conduits must be spaced and bedded in suitable backfill. This change results in $9,000.00 of constructive credit for the contract. 4) Eliminate redundant control units in system control panel. Eliminate the redundant complete PLC on the tank overflow monitoring system and provide a spare CPU and at least one of each 110 cards to serve as a backup control unit if the PLC were to fail. Since the system is designed to fail closed (or off), one preprograrnmed CPU, a spare power supply and a spare of one ofeach GWashington Lundgren, 303·843·3596 type ofI/O cards used in the system will provide sufficient backup and immediate response in case offailure, and reduce the adverse impact to the system from a lighting strike in the area which could eliminate the programming on both systems and make recovery more difficult that just changing components. Each ofthese components is to be provided in the manufactures original packaging. This change is reflected in the revised electrical drawings dated 3-23-05 and results in $18,000.00 of constructive credit for the contract. 5) Replace metal grating steps with concrete step. Replace the 10 metal grating steps in the secondary containment area with a 9" high concrete step. This change results in $1,600.00 ofconstructive credit for the contract. 6) Replace florescent light fIXtures with 250 watt metal halide lights. Replace the florescent light fixtures with low base 250-watt metal halide in two rows on each side ofthe facility. The low base fixtures cover more area with higher lumens; so fewer fixtures are needed for the same light level. This change is reflected in the revised electrical drawings dated 3-23-05 and results in $15,000.000 ofconstructive credit for the contract. 7) Fire protection coating of the canopy rafters Do not fire protect coat the shape metal rafters ofthe canopy structure. A technical review has been performed on the canopy structure performance and the conclusion is that since the proposed shaped rafters are not under load and will be supported in a fire by the rated coated columns ofeach bent, there is no reason to coat the rafters. This item has no constructive credit change for the contract. 8) Use horizontal filter/separators Use ofhorizontal filter/separators for this system is acceptable providing you can install them appropriately in the system within the space limitations ofthe secondary contaiument area and maintain access for filter changes. This item has no constructive credit change for the contract. 9) Use of aluminum case mechanical flow meters Use ofaluminum case mechanical mechanical flow meters versus double case steel meters is acceptable based on this application. Systems using two or more large volume storage tanks that would pass all fuel through one or two lines would have a much higher utilization rate and would warrant a double steel case meter. This system dispenses through 14 separate tanks and no single meter will have high volume utilization. This change results in $36,660.00 ofconstructive credit for the contract. 10) Eliminate canopy gutters. downspouts and associated underground piping Eliminate the canopy gutters, downspouts, sidewalk connections and underground PVC drain lines (E & D) and catch basin on the south end of the oil/water separator. Connect the separator outfall line directly to the existing storm sewer system by transitioning to 10" RCP line. This change results in $18,145.00 of constructive credit for the contract. 11) Use the Blackmer X2.5B 150 gpm pump Pending verification by the manufacturer for this application, use the Blackmer X2.5B ISO gpm aviation fuel pump for the AvGas tank and dispensing system. This change results in $9,876.00 ofconstructive credit for the contract. GWashington Lundgren, 303·843.3596 12) Modify the 10' & 6' vinyl covered fence structure detail Change the 10' fence detail to provide 4" diameter posts instead of3", and set the posts at 7' on center, with top and middle rails and bottom guy wire. The 10' fence remains black vinyl covered chain-link fence fabric with black slats. Change the post setting for the 6' black vinyl covered chain-link fence fabric with black slats and barbwire to 8' on center instead of 10'. Other chain link fencing remains as per plans. Shop drawings from the subcontractor will be reviewed and the additional cost must be determined. 13) Thicken the concrete pavement or structure floor 1 " Instead ofthe 12" hydrated lime stabilized subgrade, the concrete structure and pavement may be increased in thickness by 1". Subgrade must be compacted per specifications and the aggregate base course (ABC) thickness and compaction requirements remain the same. (Per verbal direction by ECS) This item has no constructive credit change for the contract. 14)Add a relaxation chamber to Jet A sYstem Addendum #2 directed deletion ofthe relaxation chamber from the Jet A system; however, the revised drawings and specifications indicate a 150 gallon relaxation chamber is required. After verification by Burns & McDonnell, shop drawings from the subcontractor will be reviewed and the additional cost must be determined.
