BY: Cyndy Knighton
CC: Thomas McLeod, Mayor DATE: June 20, 2025 SUBJECT: Southcenter Boulevard/65th Avenue S Signal Project No. 92110402, Contract No. 23-180Supplemental Agreement No. 2
ISSUE Execute a supplemental agreement with KPG, doing business as PSOMAS under Contract 23-180, for engineering and construction management services related to the Southcenter Boulevard/65th Avenue S
Signal Project.
BACKGROUND KPG was retained in late 2023 to perform engineering and design services for a new signal at the
Southcenter Boulevard and 65th Avenue S intersection. During the design process, the project team coordinated with King County Metro regarding the existing bus stop at the intersection. Metro requested that the project includes expansion of the current bus zone and Supplement Agreement No. 1 added
additional funding to the design contract, which Metro agreed to reimburse the City. Metro requested additional design beyond what was included in Supplement Agreement No. 1, which has been completed, but additional costs were incurred. The reimbursement agreement between Metro and Tukwila was
approved by Council on June 2, 2025. The project was awarded to Northwest Cascade on June 2, 2025, in the amount of $1,129,129.00. The Transportation Improvement Board increased the grant amount to the City for the additional construction expenses, covering a portion of the expanded bus zone, with Metro
covering the remaining costs.
DISCUSSION An additional $24,890 is required to cover the costs for final design and bid document preparation for the
completed work, according to Metro’s second request. This supplemental agreement adds additional funds to the contract with KPG for the expanded design.
Construction management is necessary for any active construction project and KPG has the staffing
available with the necessary expertise to manage the construction and inspection and to serve as a liaison between the City’s contractor and staff. City forces do not have adequate staffing to perform this work, but City staff will oversee the construction management work to be performed by KPG. This
supplemental agreement also adds new scope and fee for this work.

PSOMAS Project No. 9TUK010800
SCOPE OF WORK
A. PROJECT DESCRIPTION/BACKGROUND The scope of work is two-fold: (1) to add budget for design effort already furnished under Amendment 1 on the King County Metro bus zone, and (2) to provide management and engineering support throughout the construction phase of the 65th and SC Signal Improvements project in accordance with the funding requirements. The project is not federally funded and does not require domestic steel or construction materials nor Disadvantaged Business Enterprise (DBE) tracking; however, there is a mandatory 10% Apprentice Utilization Requirement. This work of the PSOMAS-lead Construction Management (CM) team includes preconstruction support, construction phase services, and preparation of record drawings as described herein. Construction Management Support Duration (July 2025 to March 2026) Assumed Durations by Task
• Administration: Task 1 starts upon execution of this Contract and lasts the duration of the project, approximately 9 months, through closeout, concluding on or about March 2026.
• Pre-Bid: Task 2 - All tasks associated with task 2 will be performed by Others.
• Pre-Construction: Task 3 begins approximately 1 month prior to Notice to Proceed (NTP) and lasts one month, concluding on the NTP date.
• Construction Management: Tasks 4 and 5 will last the duration of the working days, from NTP to Physical Completion of the Project. It is understood that a material procurement suspension is expected. See Management Reserve regarding cost assumptions.
• Project Closeout: Tasks 6 begins at Physical Completion of the Project and ends approximately 6 weeks later.
• . These services are intended to assist the CITY to administer the contract for construction performed by the CITY Contractor, confirm that the Contractor’s work is in general conformance with the Contract Documents, and assist in responding to events that occur during construction. These services are based upon the understanding that the CITY will contract directly with the Contractor and will be actively involved in the construction process to assist with making decisions, provide approvals, assist with inspections (primarily signal related) and perform other actions necessary for the completion of the construction. Inspection, certification and acceptance of King County Facilities that are not included in the contract documents are not included in this scope and are not the responsibility of the Consultant.

Contract Documents Contract Documents refer to the construction contract documents between the CITY and the Contractor. These
documents include the project plans, specifications, change orders, addendums, bid proposal package and other documents such as the geotechnical report, CITY and WSDOT Standard Plans included by reference.
Assumptions
The presence or duties of Consultant personnel at the construction site, whether as onsite representatives or otherwise, does not make PSOMAS personnel in any way responsible for those duties that belong to franchise
utilities, the CITY and/or the Contractors or other entities. Consultant presence, coordination and schedule review does not relieve the Contractors or any other entity of their obligations, duties, and responsibilities, including, but
not limited to, construction methods, means, techniques, sequences, and procedures necessary for coordinating and completing the construction work in accordance with the construction Contract Documents and any health or
safety precautions required by such construction work.
Consultant personnel have no authority to exercise any control over any construction Contractor or other entity or their employees in connection with their work or any health or safety precautions.
Inspection, certification and acceptance of King County Facilities that are not included in the contract documents
(shelter, bench, trash receptacle, etc) are not included in this scope and are not the responsibility of the Consultant.
The presence of Consultant personnel at the site is for the purpose of providing the CITY a greater degree of confidence that the completed construction work will conform generally to the Contract Documents and that the
integrity of the design concept as reflected in the construction documents has been implemented and preserved by the Contractor(s). Consultant neither guarantees the performance of the Contractor(s) nor assume responsibility
for the Contractor’s failure to perform work in accordance with Contract Documents.
The authority of the Engineer, as described in Section 1-05 Authority of the Engineer in the Contract Documents, shall rest ultimately with the CITY. PSOMAS, acting as the Consultant, shall carry out the administration of the Contract in accordance with 1-05.1 Authority of the Engineer, and as described in more detail in tasks 4 and 5, under the CITY’s guidance. Psomas will assist with the creation of Change Orders and other decisions lined out in 1-05.1; however, final review and approval of changes to the Contract between the CITY and Contractor will be the responsibility of the CITY. Review submittals compliance with the requirements of the contract for construction. Such review will not relieve the Contractor from its responsibility for performance in accordance with the contract for construction, nor is such review a guarantee that the work covered by the shop drawings, samples and submittals is free of errors, inconsistencies or omissions.
