AREN 4327. BUILDING CONSTRUCTION LOGISTICS & ERECTION SYSTEMS. 3 Hours.
Engineering of site logistics for high-rise building construction including material transportation, delivery, offloading, and on-site storage; erection planning and design of erection maneuvers; on-site soil stabilization and excavation support methods for staged basement construction (top-down & bottom-up); ground- and storm-water management; shoring alternatives for steel deck and precast floor systems; construction tolerances & accepted correction strategies; concrete pouring & curing methods for conventional and mass concrete elements under diverse climate conditions. Erection planning includes crane types & selection criteria, crane delivery & erection, crane stability (analysis & design of supports), and rigging for one-, two-, and four-point lifts. Students determine maximum crane lift weights from equipment-transformers, chillers, structural elements-and manufacturer load-capacity and radius-of-reach diagrams. Basement construction includes secant & tangent pile walls, and post-tensioned ground anchored and grouted tieback earth-retention systems (e.g., DSI DYWIDAG & Williams Form). Steel assembly logistics include pre-cambering via heat or load-induced plastic deformation, weather-dependent erection sequencing, and welding electrode storage requirements, heat straightening. Concrete logistics include pouring criteria (pump & pipe selection), vibration & consolidation, pre-cambering of field-cast reinforced concrete members, rebar splice types, and AWS/ACI-approved rebar welding processes. Prerequisite: Grade of C or better in AREN 3311; Admission to the AREN Professional Program.
