The construction package comprises multiple drawing sheets detailing the scope of work, including roof plans (sheet A1.05), first floor concrete framing plans (sheet S1.01), attic floor concrete framing plans (sheet S1.04), attic floor steel framing plans (sheet S1.04A), roof steel framing plans (sheet S1.05), and sections and details (sheet S2.01). The drawings specify structural notes covering live loads, roof loads, floor loads, gusts, concrete specifications, reinforcing steel requirements, structural steel standards, metal deck installation, and HVAC considerations. Key structural elements include metal grating details at basement and attic levels, metal pipe railing details, concrete curb details, beam sections, girder sections, concrete and steel joist details, and roof opening specifications. The structural notes reference compliance with various building codes and standards, including requirements for concrete strength (ranging from 3,000 to 4,000 PSI), reinforced steel specifications per ASTM standards, and structural steel compliance with AISC standards. The documents also address quality control requirements, submittal procedures, and material testing and inspection protocols.
