Mr. Gary Gleason, P.E. 15 January 17, 2001 <br /> GME Project No. 9256 <br /> CONSTRUCTION CONSIDERATIONS <br /> Groundwater <br /> Based on the conditions found in our borings, it is our opinion that the <br /> hydrostatic groundwater table would not be encountered during excavation <br /> or construction for this project based on the proposed depths. Water <br /> which enters excavations from surface runoff, precipitation,. or perched <br /> groundwater seepage should be promptly pumped out . It should not be <br /> allowed to stand ponded over the foundations, floor slab, or pavement <br /> bearing/subgrade soils, since standing water would soften and disturb <br /> - these soils. � <br /> The contractor should not be allowed to place concrete or fill into <br /> standing water or over soils softened in an attempt to displace these <br /> materials . This technique can result in trapping the softened soils <br /> under the building, causing excessive post-construction settlement, even <br /> if the softened zone is only a few inches thick. <br /> Equipment Selection/Soil Disturbance <br /> The soil types at this site can be easily disturbed by construction <br /> equipment, especially when the soils are saturated or during freeze/thaw <br /> conditions. It is the earthwork contractor' s responsibility to choose <br /> •M!CONfULTANTl,INC. <br />
