WORK IN PROGRESS: 1) Excavation and subgrade prepping for foundations in Area B 2) Placing concrete for walls and footings (D and C) 3) Setting forms and rebar for footings, and piers at Area C 4) Vibratory stone column installation 5) Backfilling of of sewer force main connection 6) Ongoing work on VSC installation 7) Ongoing layout work by survey crew. 8) Road grading and general site prep FIELD OBSERVATIONS: PE visited the site to review ongoing progress with the site work and foundations. 1. RBO has prepared Footing line B22 and B25 from K to area C and B and by the end of the day on 7-28 they prepared lines J/B30 to J/B32 and J.7/B35 to J.7/B33, as well as north south return at line B33 (see also attached GPI report). 2. Most of the walls and piers at Area D have been stripped and are ready for backfill and Marguerite is making final concrete placement preparations at the foundation wall from D.3 to D.24 for a concrete pour today. 3. Concrete is also being placed today for footings on line E (area C) 4. At area C Marguerite is in the process of tying rebar for footing, pier and wall placements. Footing forms are being prepared on line H and line C21 (south elevation and around south east corner) for placement later this week, and many interior column footings in area C have are formed and tied. 5. The pump station for sewer force main is in place; force main has been installed from lift station to limit of work (on 7-27) and RBO is in the process of backfilling. 6. CNC is installing vibratory stone columns at southwest part of Area A(see photo); VSC installation is due to be completed today. 7. Brennan is continuing to install controls for anchor bolts at piers in Area D 8. Processed gravel has been backfilled above cultic chambers at UGI 5. 9. Commodore is planning on having some additional trees removed as necessitated by the correction of the limit of work fence along the west edge of the site. 10. PE observed the stockpile of recycled glass for backfill around utility pipes; the new delivery appears to be mostly glass and glass detritus (see photo); there is little odor from the pile.

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    Earthwork Monitoring, Daily Field Report                                                                                      Geotechnical Partnership, Inc.  Dennis‐Yarmouth Intermediate School                                                                                                                      File No. 1814‐02   Field Representative: Francis E. Sviokla                                                                    Earthwork Contractor: Robert B Our Co., Inc  General Contractor: Commodore Builders                                                                 24 Great Western Rd., Harwich, MA 02645  404 Wyman St.,    Suite 400, Waltham, MA 02451                                       Pier Installer: CNC Foundations, 8251 Bunkum Rd.               Date on site: 7/23/21, Partly Cloudy – Mid 70’s                                                                                                 Caseyville, Il 62232                 _________________________________________________________________________________________________  This Report is a summary installation list of installed vibratory stone columns, (VSC), in accordance with Submittal #31 3400-02.0 31 3400 – Aggregate Piers, prepared by CMC Professional Services LLC, 335 E.
