WORK IN PROGRESS: 1) Excavation for underground infiltration structures 2) Installation of UGI-7 3) Marguerite commencing work 4) Trench excavation and installation of water main at west entrance drive up to site entrance FIELD OBSERVATIONS: PE visited the site to review ongoing progress with the site work. 1) At the time of observation, RBO was excavating and preparing the footing line from A/D21 to A/D25 (area D), including excavating, compacting subgrade, and installing crushed stone base. [According to the attached GPI field report for 7-06, by end of day RBO had prepared the footing line up to coordinate C/d24.7.] 2) Marguerite is mobilizing on site and was working on making forms for footings 3) Excavation was commencing for UGI-1 at the main parking area (see photo). 4) Observed installation of the DMH-2 inlets at the underground infiltration structure UGI-7 (at east access drive--see attached photo). 5) Rustic Fire Protection with RBO were in the process of excavating and installing pipe to extend the water main up to about 350’ from station avenue, up to the site entrance gate (see photo). 6) The Southern part of parking lot grade has been prepared up to about UGI-1 (see photo below) 7) The grade for the access loop road appears to be prepared more or less up to the SW corner of UGI-3. 8) The installation of VSCs by CNC was still suspended at the time of the observation (travel day for CNC crew). 9) According to Ryan DiRico of Commodore, the limit of work perimeter and tree line will need to be moved outward by about 6’, at least at critical areas (UGI-2, westernmost access loop road, etc.) PROGRESS PHOTOS EXCAVATION FOR UGI-1 PARKING LOT GRADE (LOOKING NORTH) REPORT BY: ABH Page 2 of 2 PREPARED SUBGRADE AT WEST LOOP ROAD INSTALLATION OF FOOTING LINE AT LINE A FOOTING LINE EXCAVATION CLOSE TO A/D21 INSTALLATION OF WATER MAIN GRADE FOR LOOP ACCESS ROAD NEAR PLAYGROUND PROGRESS ON UGI #4 PROGRESS ON UGI #6 INSTALLATION OF INLETS AT UGI #7    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: 7/6/21, SUNNY, MID 80’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. Geneva Rd #3116, Carol Stream, Il 60188. Glossary of Header Terms: VSC Pier #: Each pier is identified by number according to location plan included in the above referenced Submittal. Proposed Depth: Total VSC depth from working grade to proposed bottom elevation as put forth in design criteria. Installed Depth: The as-built length of pier as constructed from working grade to termination in suitable native, (bearing) soil. Stone Take: The amount of Crushed Stone used in constructing a given Pier, (expressed in volume), one cubic yard weighs approximately 1.2 Ton. Comments: Note any deviation from standard installation procedures, proposed depths or changes in location of said Pier.

The Construction trades working this day included Site contractors. During the visit, I meet with Paul Genereux, Site Superintendent and maple syrup enthusiast from Commodore Builders. The site is cleared of trees, and the topsoil is stockpiled to the North-East corner of the site. Rammed Aggregate pier installation is in progress with one installation machine. Excavations for footings have just started at the North-West Corner of area D. Stone is placed over the excavated surface. A representative from GPI was monitoring the activity. I attended a foundation pre-construction meeting, along with representatives from the concrete installer, concrete supplier, general contractor, owners project manager, and Andrew from Perkins Eastman. The meeting covered mobilization, testing, schedule, and coordination of the foundation installation. In general, the work observed appears in conformance with standard industry practice. 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_OR001.docx
