During the month of September, Alten Construction finished with the shotcrete walls and all underground utilities in the basement within the first week. Contractor then proceeded with placing and spreading the underground rock (3/4-inch rock) followed by water proofing and rebar. Contractor took extra precaution during the rebar installation assuring that the water proofing mat was not ruptured. Contractor then proceeded and poured the Apparatus Bay room and partial basement floor. Contractor also worked on off-site utilities gas, water, sewer and storm drain. The IOR and City inspector have been performing continues inspection. We have also take extra concrete cylinders to assure proper curing and design strengths are met.
