WORK IN PROGRESS: 1) Excavation and subgrade prepping for foundations in A and B. 2) (in AM) Preparation for placing concrete for walls and footings (C and B) (work suspended due to rain). 3) Dense grading at east access road. 4) Excavation and laying pipe for sewer force main. 5) Backfill and compaction from manhole 2 to manhole 3 at electrical duct bank for parking lot lights. FIELD OBSERVATIONS: PE visited the site to review ongoing progress with the site work and foundation work. 1. RBO has recently prepared footing lines at areas B and A, including lines at the south area of the gym and was in the process of preparing line W from A1 to A9 on Thursday (see also attached GPI report). 2. Up until they suspended work in the morning due to heavy rain, Marguerite had been making concrete placement preparations for footings in the J / J.7 area of the gym, as well as walls on line H. 3. Up until the rain, National Grid had been on site installing the gas main, but they suspended work. 4. The footprint of the building at Area D inside the foundations has been backfilled and leveled with structural fill; the work was done in accordance with the GAC directive to keep the backfill 12” below TOW; according to Commodore the underground plumbing work at Area D is scheduled to commence on Monday August 9, with underground electrical work to follow immediately behind. 5. Dense grade for surfacing the east road (including above UGI 3 and UGI 7) was done on Wednesday 8-4, and at the time of observation this was ongoing at the very north end of the east access road. 6. The concrete pad for the exterior wall mockup panel has been placed (located just east of the SAE east parking lot). 7. The following structures have been installed around UGI#1: Manholes #25 and #28, Catch basins #19 and #24. 8. Some trees within the limit of work were cleared on Wednesday for the force main extension to the existing treatment plant behind the High School. 9. RBO has installed sewer force main pipe from the lift station to limit of work (fence), and RBO is currently in the process of excavating and laying pipe to extend the force main from there to the treatment plant (see photo). An existing HP line was damaged in the process but will be repaired by RBO. 10. Vibratory stone column installation has been completed, and as of 8-29 CNC is no longer on site.

_________________________________________________________________________________________________  FOOTING PREPARATION:    THE SEQUENCE OF PROCEDURES ARE IDENTICAL FOR ALL INSTANCES OF PREPARATION, AND ARE AS FOLLOWS:   Excavate to six inches below proposed Bottom of Footing Elevation   Compact the exposed subgrade, Piers now revealed – with a heavy vibratory plate compactor   Place six inches of 3/4” Crushed Stone upon the Prepared Subgrade   Compact said Crushed Stone   Crushed Stone Base now ready for Footing installation                                              Activity for Thursday, August 5th, 2021:  AREA “A “  Footing Subgrade Compaction / Preparation Detail :  The soil matrix encountered at subgrade elevation largely consists of uniform sands and fine sands with scant traces of  non‐plastic silt. Therefore, the proper in‐situ compaction of this material is largely dependent on the relative moisture  content of the soil. Since the encountered materials are of native, (natural) deposition the water content can vary from  location to location. Each situation must be evaluated to determine that the proper soil compaction techniques are  utilized vis‐à‐vis the moisture content of the soil. In other words, it may be necessary to moisten some areas with  supplied water in order to certify proper compaction in these circumstances.
