WORK IN PROGRESS: 1) Steel erection, deck installation, and detailing 2) Moment welding 3) Concrete placement and placement prep 4) Underground plumbing work in Area B. 5) Site electrical work in general 6) Ongoing survey and layout work by Brennan 7) Fenagh is on site for 3rd party rebar inspections and steel inspections. FIELD OBSERVATIONS: PE visited the site on 9-29, in order to review ongoing progress with the steel erection, deck installation, site work, foundation installation, insulation installation, etc. 1. RBO completed the balance of the footing prep on 9-28. Work completed this week includes the interior footing at A10.8/S.4, the base for the wall at the auditorium lobby and lobby corridor [B.14 from S.1 to U.2], and interior footings along B12 from S.1 to S.8. (See attached photos as well as GPI field reports.) 2. Stellar Steel has completed steel erection at area C, not including bar joists, and at the time of observation the crew was in the process of erecting steel at the north side of the gym on line J.7 and at the locker room area north of the gymnasium (see photos). 3. Stellar steel is in the process of installing metal deck at area C, and deck stud installation has been completed at area D (see photo). Commodore reports that by the end of next week decking installation and detailing should be complete for both C and D. 4. At the time of observation the welding crew was making moment welds at the NW corner of area C (see photo). 5. Backfilling of areas A and B interior (up to structural fill level) is ongoing ahead of steel erection. The backfill inside the footings has been completed at the adaptive PE area, and RBO is in the process of installing the crushed stone pad at the gym area (see photos). 6. The base plate has been installed at the remediated pier at lines K/B.24. 7. Marguerite has prepped the forms and rebar for the last pour at the auditorium lower bowl area, and is in the process of preparing for the footing placement on line B14 (auditorium lobby corroder foundation wall), and adjacent interior footings in Area A (see photo). Foundation work is nearly complete overall. 8. During shop drawing review PE picked up the fact that the wall at the brick return for the Mattacheese entrance (at the corner of Q and B.21—see attached photo) was placed 3” too far to the west (because that is what was drawn), so GAC issued a drawing to correct this by padding out a 4” brick shelf here that is pinned into the existing wall (Bulletin 18). PE asked Commodore to hold off insulation and backfill here pending this correction.
