The purpose of this item is to provide an update on the bidding process, bid award, and delivery of funding for construction of the concrete ramp and associated taxiway and taxilane connectors to serve the new U.S. Customs and Airport Administration facility.
This project is partly funded by an Airport Improvement Program (AIP) Non-Primary Entitlement (NPE) grant through TxDOT Aviation. The grant award was accepted by Council Resolution passed at the February 13, 2020 regular meeting. That Resolution also designated TxDOT Aviation to serve as Addison's agent to manage this project. Following approval of the Resolution, Addison was obligated to send $66,667 in matching funds (10% of the combined total of Addison's matching funds plus the NPE grant amount of $600,000) prior to the project going to bid. The grant amount is capped at $600,000 with all additional costs for the project to be paid by Addison Airport. The remaining funding (including an amount for project contingencies) is to be provided to TxDOT Aviation following bid opening and award recommendation. The TxDOT estimate for total project cost, included in the Resolution, was $1,666,666 (the $600,000 NPE grant plus $1,066,666 in funding from Addison Airport).
The project was advertised by TxDOT Aviation, with a bid opening date of August 4, 2020. Six (6) bids were received, as indicated in the table below.

All bids exceeded the engineer's estimate. The bids also exceeded the TxDOT project estimate of $1,666,666. However, the three low bids were competitive and closely grouped, and the engineer (Garver) has recommended approval of an award to the low bidder, Fluor Heavy Civil, LLC.
The engineer has also identified potential cost savings in the project totaling $96,389.40 (including $21,400 for drainage revisions and $74,989.40 for pavement section revisions -- replacing lime treatment with geogrid -- based on pricing contained in Fluor Heavy Civil's bid). However, these changes (per TxDOT requirements) may only be implemented after the bid has been awarded.
To move the project forward, Addison will need to provide additional funding to TxDOT (in addition to the $66,667.00 already provided) of $1,100,790.58 which includes project contingency of $60,000.00 (approximately 3.5%). This exceeds the amount previously authorized by Council (in the February 13, 2020 Resolution) by $100,791.58. At the end of the project, 100% of any unexpended funds will be returned to Addison by TxDOT. |
