Limitations: The presence of our field representative at the site is to provide our client with a source of professional advice, opinions, and recommendations based upon the field representative’s observations and testing of the contractor’s work. Our services do not include supervision or direction of the contractor, their employees, or agents. Geotechnical recommendations for obtaining project objectives may be made by our representatives; however, direction of the actual work should come from the owner or contractor, as appropriate. The contractor is responsible for complying with the contract documents at all times, regardless of the presence of our field representative. Jobsite safety, including compliance with all applicable state or federal regulations, is the sole responsibility of the contractor. The observations, recommendations, and conclusions provided in this field report are preliminary until reviewed by the ESNW project manager.
Per client request, ESNW rep arrived onsite at the Weatherly Inn development to observe and document wall subgrade excavation and slope conditions. While onsite the following was observed:
Cast-In-Place Wall Excavation Observations: ESNW rep arrived onsite per request to continue observation and documentation of ongoing cast in place wall excavation and subgrade conditions within the central areas of the Weatherly Inn development. Upon arrival, ESNW rep observed the contractor was continuing gradual excavation of the wall keyway westward, and further observed that the concrete subcontractor was onsite and beginning work, with forming estimated to occur ln Monday (2/28).
The contractor was observed to have extended the wall keyway, grading additional subgrades observed to consist of unweathered grey very dense SP-SM glacial tills grading to brown weathered very dense glacial tills. ESNW rep utilized a ½” diameter steel footing probe to probe the newly completed areas of wall subgrade and observed very dense soils conditions in the locations probed. These conditions are considered suitable for the support of the proposed cast in place wall footing. ESNW rep will return for further subgrade documentation as excavation continues.
Wall Excavation Slope Stability Observations: At this time, the slopes of the excavation were observed to consist of near vertical slope faces of approximately 14’ in height at the greatest extent within the eastern areas of the excavation, falling in height and gradually changing to approximate 4-7’ near vertical faces with an approximate 1H:1V slope above the vertical portion where space allows.
The slopes of the excavation were observed to be stable and unchanging in its current temporary configuration, however it is the responsibility of the contractor to perform all necessary safety measures in accordance with state and
federal regulations. It is recommended that the contractor inform ESNW if any changes in the slope conditions occur.
Please refer to the attached plan detail and photo documentation provided below. ESNW rep will return per request of the client.
