REPORT TO CITY COUNCIL
To: Honorable Mayor and Members of the City Council
From: Jason Simpson, City Manager
Prepared by: Shannon Buckley, Assistant City Manager
Date: November 14, 2023
Subject: Amendment No. 1 to the Professional Services Agreement with Engineering Resources of Southern California, Inc. (ERSC) for the Civil Engineering Services of the New City Hall Project (CIP Project #Z20006) Recommendation
Approve and authorize the City Manager to execute Amendment No. 1 to the Professional Services Agreement with Engineering Resources of Southern California Inc. (ERSC) in the amount of $44,032.00 for Civil Engineering Services of the new City Hall project (CIP Project Z20006) in such final form as approved by the City Attorney.
Background
The City engaged the services of Engineering Resources of Southern California Inc. (ERSC) to provide civil engineering design services and preparation of supporting documents for the new City Hall project. As the final parcel comprising the project site has been acquired and architectural drawings completed, the demolition and grading plans, water and sewer plans and the water quality management plan require modification and completion consistent with the configuration of the final project design. These services are needed to create an engineered building pad for the new City Hall facility. ERSC and the City's architect, STK Architectural, will work together with the help of Dennis Janda Surveying to establish an engineered build site complete with utility connections.
Discussion
The services reflected in the proposed Amendment No.1 to the Professional Services Agreement are in addition to the original civil engineering services for the project's site development. They will include the needed civil engineering construction documentation to affect the utility connection and modified site development. Essential tasks are included in the following:
ERSC Amendment No. 1 New City Hall Project
8 3
0 Precise Grading Plans
Modification of demolition of the east half of the existing alley and addition of demolition across the building frontage on Main Street/Graham Avenue from the face of the building to the back of the curb.
Modification to grading design along the rear of the revised building footprint to provide access and drainage.
Modification of grading along the alley to accommodate future construction of parking east of the alley. The parking lot east of the alley will not be constructed with the current project. Design of parkway improvements and curb ramps along Main Street and review and analysis of sidewalk grades along Graham Avenue to verify compliance with accessibility requirements. Design in these areas will provide accessibility in compliance with Chapter 11 of the California Building Code.
Water Quality Management Plan
Evaluate the most viable treatment methods usable within the limits of the project site. Modification of the project-specific water quality management plan to delete the proposed parking in the existing alley and add the new building footprint and the area across the project frontage of Main Street, including, but not limited to, the project description, design control volume and design flow calculations, BMP calculations, and redesign of the WQMP site plan.
Utilities
Prepare and submit a revised Due Diligence meeting request form to EVMWD. Process revised drawings for review and approval by EVMWD. Modify sewer and water plans to accommodate a sewer connection in Main Street and eliminate sewer and water reconstruction in the alley.
Relocate the DCDA, PIV, fire department connection, fire hydrant, and domestic water supply to the south side of Graham Avenue.
Design piping to the connection point for the fire supply line and domestic water connection per current Plumbing Plans.
Since the City acquired the building located on 114 South Main Street, the current site for the new City Hall has expanded in width. As a result, STK Architecture, Inc. (STK) has modified the City Hall plans to provide a building that encumbers the previous three parcels and the current acquisition. The acquisition of the additional parcel allows for a reduction of the east/west dimensions of the building such that construction will only minimally impact the existing alley and preserve badly needed parking. Consequently, certain utility relocation and alleyway redesign services are no longer necessary for the project.
ERSC Deliverable Services Will Include the Following Major Elements:
Modified Demolition, Grading, and Erosion Control Plans Modified and restated Water Quality Management Plan
Modified Water and Sewer Plans
CADD files for use by SCE
