The Riley Group-Final Report 11.12.2013.pdfit The Riley G'a oup, Inc. November 12, 2013 Mr. Brian Mattson McDonald's USA, LLC 12131 113th Avenue Northeast, Suite 103 Kirkland, Washington 98034 Subject: Final Inspection Repoli Edmonds McDonald's 46-0084 Edmonds, Washington RGI Project No. 2012-198 Dear Mr. Mattson, As requested, The Riley Group, Inc. (RGI) provided construction monitoring services on an on call basis for the project from August 7, to November 11, 2013. RGI previously provided a Geotechnical Engineering Report (GER) and critical areas study and infiltration system recommendations for the project. RGI's geotechnical engineer or geologist visited the site and observed the earth work during the construction as requested by the contractor, EM Precision. Our observations and conclusions are documented in Daily Field Memos and copies were left at the construction site at the end of the day. Based on our observations, the earthwork was completed in general accordance with the recommendations in the original GER and the requirements of the City of Edmonds. The following outline our observation on the site: 1. SOIL BEARING CAPACITY The building is supported on perimeter footings and isolated columns bearing on dense native soil or structural fall. Based on our observation of the native foundation subgrade and the placement of structural fill, the native soil or structural fill is suitable for the design bearing capacity of 2,500 pounds per square foot (psf). 2. EXCAVATION OBSERVATIONS RGI observed excavations for mass grading excavation, footings, and utility trenches during construction. Our observations indicated that all of the excavations were performed in medium dense to dense native soil. The existing natural slope and temporary cut slopes were observed to be in stable condition. No significant soil movement was observed on the site or adjacent properties. 3. STRUCTURAL FILL AND COMPACTION RGI observed major site grading such as site fill placement. Fill placed on site was placed as structural fill and compacted. RGI also observed the installation of the site utilities. The native soil was used for backfilling. Utility backfill was placed in lifts and compacted, In place density SGRVr3NG THE PAUMc NORTHWEST Tueoma, Washington Corporate Office Kenrrewiclr, 111ashhrgion Phone 253.565.0552 17522 Bodrell Way Norlheast Phone 509.586.4840 Bothell, Uashinglan 98011 Pham 425.415.0551 • Fax 425,415,93 11 ivi isr, rrley-grotrl�. tour Final Inspection Report Page 2 November 12, 2013 Edmonds, [Vashinglon RGI Project No. 2012-198 tests in the fill and utility backfill indicated at least 95 percent of maximum dry density per ASTM D1557 in the areas tested. 4. SUBSURFACE 1DRAINAOIj AND STORM WATER INFILTRATION GALLERY RGI observed the placement of the subsurface drainage system. The drainage installation was completed in general accordance with the approved plans and specifications. RGI observed the installation of infiltration gallery. The bottom of the facility was installed as shown on the plans and native soil was exposed under the facility. The native soil observed was consistent with the soils encountered in our infiltration study. 5. MOCKERY INSTALLATION AND REPAIR RGI observed the construction of a section of rockery to the west of the new building. The rockery was supported on firm native soil and installed per industry standard. RGI also observed. some rockery repair work done by the contractor. The rockery has been inspected by the contractor and loose rocks have been replaced as needed. G. EROSION CONTROL During our site visits, RGI representatives did not observe erosion on the site or sediment tracking onto the streets, the public stormwater system, existing slope, or adjoining properties during construction. At the time of preparing this report, landscaping had been completed. The permanent erosion control has been established. No further visits are needed. The Daily Field Memos are attached to this letter. If you have any questions or require additional information, please contact us.
