General Construction in Steel — Code of Practice
Limit state design criteria for hot-rolled and cold-formed structural steel members, tension members, columns, flexural beams, and welded/bolted connections.
Guidelines for Concrete Mix Proportioning
Standardized calculations for ordinary and standard concrete mix design using absolute volume methodology, target strength, and water-cement ratios.
Methods of Measurement — Earthwork
Standard specifications for civil engineering measurement of earthwork excavation, lead, lift, surface dressing, backfilling, and cutting in various soils.
Code of Practice for Prestressed Concrete
Structural engineering principles and limit state design for prestressed concrete members, loss of prestress, tendon anchorages, and deflection limits.
