Earthwork, steel, concrete construction: Basement area has WF steel soldier beam, timber breastboard, tie back temporary retaining wall in left center. Bundles of resteel sit at grade level behind retaining wall, and two horizontal cables provide excavation edge fall protection. Right center bottom to top cast-in-place (CIP) reinforced concrete foundation piers sitting on CIP spread footings below and support base plates for H-section columns for superstructure. Protruding from piers are rebars, in circular pattern in piers, and 4 anchor bolts for column base plates. The rebars will be cut off before base plates and columns are set. heavy copper wire also protrudes from top of piers that is also attached to an electric ground plate in soil at bottom of footing. The cable will be attached/ spliced to metal above to provide an electic ground for building. Resteel extends above CIP foundation wall at bottom and upper right to provide reinforcing continuity at joint with future wall above and CIP slab to right. Backfill at bottom of excavation is sand, and additional granular material at top rear will later provide vertical support for CIP slab. Pink polystyrene sheets stacked in excavation will provide insulation when attached to exterior of foundation/ basement wall, as at mid-height far right.
