    BRIEF

    Policy Summary

    Berkeley Lab requires design and construction of new buildings and other facilities on Laboratory or University of California premises to comply with current seismic provisions of the California Code of Regulations (CCR), Title 24, California Building Standards Code, or local seismic requirements, whichever requirements are more stringent.

    Who Should Read This Policy

    POLICY

    A. Purpose

    To provide an acceptable level of seismic safety for Lawrence Berkeley National Laboratory (Berkeley Lab) employees and affiliates who occupy buildings and other facilities on Laboratory or University of California premises to the maximum extent feasible by current structural engineering practice

    B. Persons Affected

    This policy applies to Laboratory project managers and subcontracted architects and structural engineers who work for the Facilities Division.

    C. Exceptions

    This policy is optional and at the discretion of the Laboratory Building Official for buildings that are under the jurisdiction of an outside agency (for example, the State of California Division of the State Architect or the Office of Statewide Health Planning & Development) and small projects that the Laboratory Building Official determines do not involve structural work requiring design by a consulting structural engineer.

    D. Policy Statement

    1. Code Compliance: Berkeley Lab requires design and construction of capital projects for new buildings and other facilities and major modifications of existing buildings on Laboratory or University of California premises to comply with current seismic provisions of the California Code of Regulations (CCR), Title 24, California Building Standards Code, or local seismic requirements, whichever requirements are more stringent.
    2. Berkeley Lab Facilities Division Structural Engineer Review
      1. Preliminary plans for new major capital improvement projects proposed for construction must be examined by the Berkeley Lab Facilities Division structural engineer, who will prepare recommendations regarding any special criteria that should be recognized in providing adequate resistance to seismic forces to minimize the risk of injury to persons and of damage to property.
      2. Final plans and structural calculations must be reviewed by the Berkeley Lab Facilities Division structural engineer for completeness, general accuracy, structural details, and compliance with any special criteria previously established. Should seismic design standards be revised during the period between completion of final plans and the date of advertisement for bids, the Berkeley Lab Facilities Division structural engineer will again review the plans and structural calculations before advertising for bids. The design structural engineer will incorporate all comments into the plans prior to bidding.
    3. Independent Seismic Peer Review: An independent seismic peer review shall be conducted on all new major capital improvement projects, whether new building construction or major modification to an existing building, that involve structural design and that are intended for human occupancy or that affect life or safety of the occupants. The Facilities Division will provide for the selection of the reviewer and plan for the review.
      1. Exceptions: Independent seismic peer review is optional and at the discretion of the Laboratory Building Official for:
        1. One- and two-story wood-framed buildings of less than 3,000 square feet
        2. Buildings not intended for human occupancy
        3. Small projects that the Laboratory Building Official determines do not alter any building lateral force resisting structural systems
    4. New Building Location: New Laboratory buildings must not be constructed on the trace of an active geologic fault.
    5. Approval of Variations from Policy: Unless this policy explicitly and specifically authorizes an action, the action is considered to be a variation from the policy and must be approved in advance by the Laboratory Director.

    The Structural Engineer-of-Record for a capital improvement project

    Independent Seismic Peer Review

    An objective technical review by an independent reviewer to provide independent, knowledgeable review of potential buildings or other facilities prior to Berkeley Lab lease, licensing, or acquisition by purchase or other title transfer; also provides a measure of additional assurance regarding performance and safety of new construction and repair or renovation of existing buildings. The reviewer shall not be an employee of Berkeley
    Lab.
