Technical Standards & Documentation Audits

We structure all quantity takeoffs under CSI Division 07 - Thermal and Moisture Protection using measurement principles from Roof surface areas measured in roofing squares (1 square = 100 square feet) and Slope pitch multipliers applied to flat projected CAD areas (e.g. 6:12 pitch = 1.118 multiplier) and Parapet wall flashings measured in vertical square footage and linear footages of coping cap. Line items reflect local code criteria defined by Western Riverside County Multiple Species Habitat Conservation Plan (MSHCP) fee assessments, SCAQMD Rule 2305 (Warehouse Indirect Source Rule), and regional traffic mitigation ordinances.
