Architectural & Engineering Design Services For A New Household Hazardous Waste Facility

The Sonoma County Waste Management Agency, which is also known as Zero Waste Sonoma (ZWS) is
soliciting proposals for architectural and engineering design services for the new household hazardous
waste facility (HHWF) and offices. These services are crucial to preparing construction ready plans,
specifications, and estimates (PS&E) as part of the construction bid package.

1. PROJECT BACKGROUND AND DESCRIPTION
ZWS currently extends household hazardous waste (HHW) disposal services through a 6,000
square foot facility based in Petaluma. However, for residents of the northern half of Sonoma
County, this location is highly inconvenient due to significant travel distance involved. This
deters proper HHW disposal among this population and elevates the risk of improper disposal
techniques, which could detrimentally affect the environment and public health. ZWS purchased
a property in Windsor, California with Assessor’s Parcel Number (APN) 059-271-082 to construct
a new HHWF and office building. There are three existing structures and a creek on the parcel.
The proposed HHWF aims to mitigate these concerns by enhancing accessibility to HHW disposal
services. Additionally, the inclusion of office and meeting spaces within the new facility is
planned to facilitate administrative functions and support services, further promoting
environmentally responsible waste management practices, and improving the overall efficacy of
hazardous waste collection in the region.
The project involves salvaging materials from an existing cross-shaped building, demolishing
three existing structures, and then constructing a new office building alongside a new HHWF.
This initiative emphasizes environmental sustainability by reusing valuable materials and
providing essential infrastructure for both administrative needs and safe HHW disposal.

2. DESIRED GOALS/OBJECTIVES/OUTCOMES
The intent of this RFP is to determine the proposed scope of the A&E Design Services. The
agreement resulting from this RFP will be a Professional Services Agreement (PSA) for the A&E
Design of the HHWF, with potential inclusion of offices depending on a subsequent cost
comparison between incorporating offices in this project versus leasing separate office space.
The selected Consultant should be prepared to evaluate multiple design alternatives and
provide construction ready, permitted PS&E’s by the end of 2026. Overall project objective is to
complete construction of a larger HHWF by fall of 2028. The Consultant will determine the
appropriate footprint necessary to construct a HHWF with approximately 66% more capacity
than the existing HHWF in Petaluma while considering the constraints of the parcel. Attachment
B details the maximum capacity of the 6,000 square foot HHWF in Petaluma. The project
includes the deconstruction and demolition of existing buildings, and the construction of a new
HHWF, with the inclusion of offices subject to further financial evaluation.

Proposals must be received no later than 5:00 P.M. on Friday, October 4, 2024
