WORK IN PROGRESS: 1) Underground plumbing work in Area C. 2) Underground electrical work in Area D link 3) Insulating and Backfilling foundations at Area C 4) Concrete placement at Area A 5) Setting forms and re-bar in preparation for future concrete placement at Area A 6) Ongoing survey and layout work 7) Fenagh is on site for 3rd party rebar inspections and compaction testing FIELD OBSERVATIONS: PE visited the site to review ongoing progress with the site work, underground utilities and foundation installation. 1. On Monday RBO completed subgrade prep for the elevator pit in Area B, as well as for the remainder of the interior footings at the music wing area (Area A), and today was continuing to prepare interior footings subgrade in the central part of B (specifically on line L on B17 to B21 and also on lines M and M.5). see photo. Also see GPI report for more detail. 2. RBO is preparing subgrade for transformer pad (see photo). 3. UG plumbing and electrical work at area D is substantially complete, and RBO has loaded crushed stone into at the Area D future slab on grade so that final preparations can be made for the subgrade for the slab (see photo) 4. Harold Bros. is currently trenching for underground plumbing at Area C (see photo). 5. Foundation insulation has been placed and walls backfilled at most of area C, including the courtyard and the C-D links 6. In the early morning Marguerite placed the central foundation wall along the north side of Areas B and extending into A—i.e. on line B12.3 up to line K, and on line K up to B1; they also placed concrete for knee wall footings at the auditorium ‘lower bowl’ area (see photos). 7. Forms have already been set for the music wing south wall, and around to the auditorium (lines W/A.1). It was sprinkling lightly at the time of observation, and Marguerite was in the process of tying rebar and setting forms for interior column footings at Area A, and for the continuation of the foundation wall on line A2 (auditorium West). 8. PE had a discussion with Commodore about the extent of structural foundation wall detail 3/S201, which was not dimensioned in plan on the drawings; PE provided a clarifying sketch and also walked Commodore through clarifications that the design team provided on the loading dock area rebar shop drawings. 9. Commodore said that Marguerite protected the work that was placed today in preparation for expected rain. 10. Brennan is doing ongoing ‘as built’ surveying of anchor bolts for Norgate (area B).
