(KPG), to include the 119th St. Pedestrian Crossing design and construction management services into the 2023 Annual Overlay Program contract. BACKGROUND Every year, Public Works (PW) issues a construction project to grind and overlay several blocks of roadways in the City of Tukwila. The annual overlay program is intended to preserve and maintain the street structure in a safe and useable state by resurfacing before failure, which also minimizes costs. Before work can commence, an engineer of record is required to prepare, design, and manage construction of the project. KPG provides a unique blend of knowledge and understanding of the City's overlay program that provides efficiency and benefits which cannot be matched at this time by any other firm. KPG has also performed very well in providing construction management services. DISCUSSION As part of the program described above, PW has a grant that funds the design and construction of a raised crosswalk located on 42nd. Ave. S and S. 119th St. that will provide a safer, more accessible pedestrian crossing. PW included this design into the overlay program to ensure that it is constructed timely. As a standalone project, the 119th pedestrian crosswalk could result on little to zero construction bids. By including it in the overlay program, the scope of work is bundled with other work and becomes more attractive to prospective bidders. KPG has provided an amendment, scope of work, and fee estimate to complete the design of the S. 119th crosswalk and advertise for construction bids.
