For purposes of this interpretation, the estimated construction cost shall be determined at the completion of project design. For the purpose of determining estimated project cost, the scope of the project shall be limited to construction on one site only.
In accordance with Education Code Section 17280, the estimated construction cost used in determining exemption from DSA review shall not include the cost of air-conditioning equipment1 and insulation materials2, and installation cost of such equipment and materials when such installation does not cause structural alterations3 to a school building (i.e., affects primary or secondary framing members). In cases where such installation causes structural alterations to a school building, the provisions of Title 24, Part 1, Section 4-309 will apply and the project may require DSA review and approval.

2 For purposes of this provision, insulation materials must be of the same type as previously installed in accordance with building standards.
3 For purposes of this provision, the exclusion of HVAC-related cost is valid only when a determination of no structural alteration is made by a California-registered structural engineer in accordance with requirements of Section 1.2.1 of this IR.
