Background

Warehouse Buildings B, C, D and F were built in the 60’s or earlier with structure steel framing and sheet metal roof and siding. There have been no structural upgrade though many building code changes had happened over the years.

Building B, C, and D are mainly used for storing tools, equipment, parts and materials. Building B was once Operations offices and is now used for warehousing. WMWD uses different types of storage racks and some are anchored to the ground with one bolt at each leg. There has been no seismic assessment on these storage racks. Catalogs of anchor and storage racks used at these buildings are attached in appendix F.

A minor tenant improvement project (Appendix C) to convert the east part of Building B into warehouse office, UPS shipping and receiving area, and security tool storage room are expected to start soon. The consultant planning assessment activities should

2

anticipate these construction activities and coordinate with the Project Manager of the tenant improvement project.

Building F was used for filtration to produce potable water. Filtration equipment and facilities were left inside the building after filtration activities were abandoned. Demolition to remove the remaining equipment and facilities shall not cause damages to building structure. Repair work shall be designed if demolition is anticipated to damage the building structure. A concrete floor slab with proper base installed at proper elevation is desired after demolition is done. The intended usage of the building is for warehousing WMWD tools, equipment, parts, and material with storage racks. Coordinate with Operations’ warehouse staff for the disposal or salvaging of waste or equipment. Operations staff may participate in part of the demolition work, and the converting of filtration facilities to storage area can be done area by area to the control cost of contracts.

Scope of Operations Center Warehouse Buildings Seismic Retrofit

Building B:

See pictures in Appendix D. This building is a composite building with a structural steel framing with diagonal tie bracings at a few place on the west side of the building and masonry walls with structural steel roof beams on the east side of the building. A warehouse management office, a UPS shipping receiving area, and a secured tool room are to be built on the east end inside the building. The new construction is lumber framing and bearing walls with dry wall cover. The west part of the building is used for storage with installed metal storage racks. Since building as-built drawings are not available, the consultant shall field investigate, including coring and sampling, existing structural properties to regenerate drawings of the existing structure. Analyze the existing structure based on the most current California Building Codes (CBC). Design retrofit if the existing structure fails to meet CBC requirements.

The consultant shall assess the conditions of the existing structural elements, including corrosion on structural steel, metal roof and siding, and make repair and maintenance recommendations as required.

The consultant shall investigate storage racks used in the building including storage weights, rack material, dimensions, and anchoring system. The consultant will analyze the storage racks and recommend upgrades to meet CBC seismic requirements. The consultant may propose different storage racks. The consultant shall develop standard drawings for storage racks and rack anchoring system.
