Auto Service Center and Pit Stop – 3550 3rd St – San Francisco (Waymo)
Project Overview
The project will consist of the tenant improvement of a one-story, 11,000 square-foot building to be converted into a vehicle service center and pit stop located at 3550 3rd Street, San Francisco, California 94124. The renovation will include new interior layouts and design for HVAC, power and lighting, and plumbing, as well as exterior water and power for cleaning stations, parking and site lighting, EV chargers, security booth power and data, and four motorized gates. The project will be in one phase / permit and designed in REVIT (LOD 300). Revit model will be updated weekly.
Project Scope
Comprehensive MEP Design Services
Lam + Tea Engineering provided full Mechanical, Electrical, and Plumbing (MEP) design services for this project, ensuring that all systems were thoughtfully coordinated to support the project’s functionality, safety, and efficiency.
Electrical Engineering
The electrical scope includes reviewing available as-built or record drawings and conducting site observations to assess existing conditions, including determining the tenant’s electrical point of connection. Existing conduit and feeder sizes and routing distances may not be fully verifiable during site visits and could require further invasive investigation by others. The scope also includes evaluating the existing electrical system capacity and anticipated loads to determine if additional electrical equipment—such as panels or transformers—is required. A complete interior electrical system design will be provided, including an interior lighting circuiting plan based on the Architect’s lighting fixture layout and specifications (lighting design services are excluded, and all photometric calculations will be provided by others). A lighting control diagram illustrating control intent will be prepared, together with a diagrammatic layout of Title 24-required control devices and a sequence of operations chart for lighting controls, with final control details to be provided by the manufacturer. State-required lighting energy compliance forms (Title 24) will be included. The design will also include a power circuit plan reflecting general power distribution, connections for Client-provided equipment and building systems, and power for mechanical and plumbing systems, based on the Architect’s CAD power/receptacle layout. Vendor-specific wiring diagrams, controls, and related information will not be included in the design documents. Low-voltage requirements will be integrated through empty conduit layouts based on sketches provided by others, and 120/208V power for systems equipment will be coordinated (all low-voltage device specifications, layout, and wiring by others). A single-line diagram will be developed based on available field information and/or as-built documents, with the extent limited to verifiable conditions, along with voltage drop and short-circuit (AIC) calculations as applicable.
The scope also includes exterior electrical system design, consisting of circuiting plans for exterior power requirements—including powered gates, security booths, and cleaning stations—based on locations and specifications provided by the Architect. Exterior lighting circuiting plans will be prepared, with fixture layouts and specifications by the Architect (lighting design services excluded). Exterior lighting control intent and diagrammatic layouts of Title 24-required control devices will be provided, including a sequence of operations chart, with final manufacturer-level diagrams by others. Title 24 exterior lighting energy compliance calculations and forms will also be included. As an add alternate service, design for permanent backup generator(s) to serve the full building load may be provided, including transfer scheme and distribution layout, and coordination of construction administration related to the additional equipment. AQMD permit application services are excluded and shall be performed by others.
Mechanical Engineering
The mechanical scope includes reviewing available as-built or record drawings and observing existing site conditions to support the design of the building’s HVAC systems. The scope includes the design of heating, ventilating, and air conditioning systems; building management system (controls); and heating throughout the facility (ERV or equivalent). All new HVAC equipment will be specified and designed, including new air distribution layouts, exhaust systems for restrooms and/or kitchens as required, and the design of new return and supply diffusers. Ventilation for the water heater and cooling for low-voltage rack/equipment will also be provided. State mechanical energy compliance calculations and Title 24 forms will be included.
Plumbing Engineering
The plumbing scope includes the design and specification of plumbing systems, including hot and cold-water systems, waste and ventilation piping, building storm drainage piping, and natural gas systems as required. Fixture load calculations will be provided along with plumbing riser diagrams where applicable. Coordination will be conducted with the Landscape Architect and Civil Engineer regarding points of connection. Piping to LID features will be specified and designed by the Civil Engineer. Site drainage design is excluded from this scope. Design of compressed air and process piping distribution systems is included.
