REQUEST FOR PROPOSALS
1. Introduction
The City of Lathrop, through its Department of Public Works, is soliciting sealed proposals from
qualified consulting firms to provide professional architectural and engineering design services for
procurement and construction of a prefabricated metal storage building to be used to store
municipal fleet vehicles and heavy equipment.
2. Project Overview
The City of Lathrop Corporation Yard site is located at 2112 Louise Avenue in Lathrop, California.
Several existing facilities are located at the site, including the original corporation yard building
and Louise Avenue Water Treatment Facility and several recent additions including a Police
Evidence and Storage Building and Interim Animal Shelter. Additional facilities are planned to
include a Public Works Administration Building and the Corporation Yard Storage Building. The
City has retained a consultant (Westwood) to provide land surveying and civil engineering design
services for the surrounding site area and utilities for the Corporation Yard (see Attachment A).
Cooling measures for the storage building will consist of insulation, reflective roof coating,
ventilation and evaporative coolers to meet the ideal temperature range for vehicle storage (75 to
85 degrees F.). Although the current need is just for vehicle and equipment storage the City would
like the building design to allow for the addition of future improvements such as air conditioning
and bathrooms that would be needed for employees to occupy and work inside the building.
3. Building Specifications
The City has developed the following building specifications:
* Dimensions: 90 feet wide x 200 feet long x 16 feet high
* Roof: 2:12 gable roof pitch
* Cladding: 26-gauge roof and wall panels
* Structural System:
Structural I-beams
o
X-bracing in roof and wall sections
o
* Accessories:
Roll-up frame openings (quantity and size TBD)
o
Walk door trims
o
Fasteners, anchor bolts, and all related structural components
o
The building shall be designed as a pre-engineered metal building (PEMB) system. The metal
building package may be from Huff Steel Building or an approved equal, subject to City approval
and applicable procurement requirements. The design shall accommodate delegated design by the
manufacturer.
