S1-4 Drawing.jpeg

This is a specification document detailing construction requirements and design standards for a structural project. The document provides guidance on framing members for mechanical trades, structural planning procedures, and safety protocols for construction activities.

The specification establishes design loads for the project including: winds at 70 MPH, roof live load of 25 PSF, existing floor live load of 75 PSF (including partitions and ceiling/mechanical allowance), main roof ceiling and mechanical allowance of 15 PSF, and penthouse floor live load of 50 PSF. Key construction requirements include bracing the entire structure to maintain stability until completion and functionality, verification of exact size and location of all wall, floor, and roof openings prior to shop drawing submission, and removal of any existing building materials or structure required for performance of work with weather-tight patching maintained throughout. The contractor bears sole responsibility for safe site conditions and must apply safety requirements continuously, not limited to normal working hours. The engineer's construction review does not extend to adequacy of contractor safety measures. The document also specifies expansion anchor installation procedures, requiring location of existing reinforcing steel, drilling holes at the same nominal diameter as anchors, cleaning holes with blow-out bulbs, driving anchors to ensure at least six threads are below the top surface of fixtures, and tightening to manufacturer-recommended torque values using a torque wrench.
