The Construction trades working this day included Site contractors. During the visit, I spoke with representatives from Commodore Builders and PMA. Andy Hazelton and I walked the site and attended the weekly owner meeting. Aggregate pier installation is in progress with one installation machine. Excavations for footings are continuing into Area C and will be following the RAP installation South. Stone is being placed over the excavated surface, and a representative from GPI was monitoring the activity. Concrete installation is in progress. Area D footings and walls are in various stages of completion. Interior footings and piers, the North and East footings and walls, and the West footings are installed. Formwork is in place along the West wall, and reinforcing is installed. The observed reinforcing size, spacing, and cover are in conformance. I had a brief conversation with the reinforcing foreman to review his general procedures and found them to be acceptable. The concrete visual quality of the finished concrete is good, with no voids or indications of formwork failures. Anchor rods for the building columns are set with plywood templates, and the exposed threads are protected with heavy tape. The formwork for the column footings was simplified at line A columns, d6 and d8. Additional plain concrete was placed between the column footings creating a monolithic placement. The contractor was informed that any deviation should be brought to our attention prior to procceding with the work. We have reviewed this condition, and it is acceptable as installed. Additional concrete is placed at the footing elevation under the exterior aprons. This additional concrete will simplify the wall formwork and is acceptable. Footing penetrations were reviewed with Paul Genereux. Final underground coordination will require a wall footing penetration at line c21 between columns F.5 and G. The wall footing penetration detail can be used at this location. It will be acceptable to eliminate the wall footing between the faces of the column footings. Field Observation Report - 02 Dennis Yarmouth Intermediate Middle School Yarmouth, MA Page: 2 of 2 Girard and Company, LLP July 27, 2021 The schedule was reviewed with the commodore. There is a need to backfill the interior area without backfilling the exterior, creating an unbalanced load on the foundation wall. We asked that the contractor submit an RFI with this question. We will review and provide direction through the RFI response. In general, the work observed appears in conformance with standard industry practice. Other than the items noted above, there were no apparent deficiencies noted. Respectfully, Girard and Company, LLP Kenneth P. Anderson, PE Field observations performed by Girard and Company, LLP are not detailed inspections and do not relieve the contractor from their obligations under the construction contract, including but not limited to the construction means and methods and job site safety. The purpose of the field observations is to verify that the progress of work is in general conformance with the contract documents. file: H:\2017\17-030 Dennis Yarmouth MS\Construction Control\OR\17030_OR002.docx
