TO:
MDTA Board
FROM:
Chief Engineer James Harkness, P.E., PTOE
SUBJECT:
KB-4903-0000 – Key Bridge Rebuild Progressive Design Build - Contract Modification 1
DATE:
May 29, 2025
PURPOSE OF MEMORANDUM To request approval of Modification 1 for Contract No. KB-4903-0000, the Key Bridge Progressive Design-Build (PDB) contract, and receive approval to negotiate Early Work Packages (EWP) to a determined not-to-exceed amount. SUMMARY The Key Bridge Rebuild project is the first time the MDTA has utilized the PDB project delivery method. The services for this contract were procured by a Request for Proposals (RFP), which was advertised on May 31, 2024, and four proposals were received on June 24, 2024. After a thorough evaluation, the project was awarded to Kiewit Infrastructure Company (KIC) on August 29, 2024. This contract amount served as a not-to-exceed figure for Phase 1 – Project Development services. This original amount was increased to allow for geotechnical and foundation testing consistent with the Phase 1 scope of services. See below for a summary of the Phase 1 Contract. Date Description Amount Award 8/29/2024 Phase 1 – Project Development Services $73,000,000.00 Change Order 1 1/28/2025 Test Pile Procurement $10,604,456.84 Change Order 2 4/24/2025 Load Test Program $32,352,283.00 Total $115,956,739.84 Under the PDB model, MDTA and KIC are working collaboratively to develop the construction scope, means and methods, schedule, and remaining data collection and design activities. These services will be provided as part of the Phase 2 Contract (Project Delivery services). During the Phase 1 work and while developing the Phase 2 scope elements, it has become apparent that certain activities need to move forward to construction via EWPs to allow for work to be performed on the critical path without materially impacting the Phase 2 Contract negotiations and estimating. Each EWP will include a defined scope of work, schedule, and cost.
