Codes Committee

The Codes Committee consists of five members appointed by the DES Director (AHJ). All members are registered professional architects and/or engineers with specific training and experience in implementing and interpreting the applicable codes. Appointments to the Committee are for two-year terms. Current Committee members include:

  • Alex Gamble, AIA (Chairperson)
  • Samuel Vega-Cotto, PE (Vice Chairperson)
  • Steven Anderson, PE
  • James Aberle, AIA
  • Nick Lu, SE
  • Paul Ninomura, PE

When faced with interpretation questions relating to IHS facilities and projects, IHS Staff and Tribal representatives may request a formal interpretation by the AHJ. Requests should be routed through the Area Facilities Manager and/or Safety Officer to the DES Director (AHJ). The standard protocol for responding to interpretation requests is for the Committee Chair to confirm receipt of the request within 14 days. The confirmation will provide an estimated timeframe for issuance of the interpretation and may ask for additional information necessary to complete the interpretation. Interpretations should be rendered within 28 days after receipt of all necessary information, and can be expedited when timing is critical.

More detailed information regarding Committee organization and protocols may be found in OEHE Technical Handbook Chapter 4-3 Codes Committee Organization. [PDF - 218 KB].
