August 11, 2025
Request for Proposal (RFP)
The Douglas Flat Community Center (DFCC) seeks qualified Contractors for the following scope of work. Bidders must have a California State Contractor’s License, General Liability insurance and Workman's Compensation insurance. The building permit will be the responsibility of DFCC.
Background
This is not a prevailing wage job. DFCC is a private non-profit corporation 501(c)(3) run by volunteers dedicated to preserving the school and grounds for the benefit of our community. Our revenue is from memberships, rentals and tax-deductible donations of money, services, and materials. Bidders are encouraged to show a line-item adjustment for the value of donations, if any. DFCC is grateful for donations that advance our purpose and will provide receipts for the value of in-kind donations.
This job qualifies for the California Historic Building Code. Information about the historical significance of the Schoolhouse is available on our history page. The Secretary of Interior Standards (SIS) guidelines applicable to this work are attached to the RFP.
The Schoolhouse
The schoolhouse was jacked up onto cribs to access the underside for new work.
The building is located at 1330 Main Street Douglas Flat, California. The historic building is 20 x 40 feet and was jacked up four feet above grade in June 2025. There is a 14 x 16 foot Annex (kitchenette and toilet) at the back. The Annex sits on a perimeter foundation on three sides with piers under where the two buildings were attached. The modern Annex has a functioning toilet, sinks and electrical power available for contractors’ use.
Scope of Work
The selected contractor will provide all equipment, personnel and materials to complete tasks described below and in accordance with the Building Permit Plans by WRF Engineering.
Please bid all or any of the following three tasks separately. DFCC reserves the option to select different contractors for each.
