The client may realize benefits through the excavation of test pits and other fonns of evaluation whether such work has been explicitly recommended or not in Nutting Engineer's report. Such methods may be more likely to identify buried debris than . small diameter discreet soil borings if exploration in the area of such debris is performed. The. method of detennining the boring location and the surface elevation at the boring is noted in the report This information is represented OD a drawing or on the boring log. The location and elevation of the boring should be considered accurate only to the degree inhem1t with the method used. n u n LJ II LJ II LJ II The soil boring log includes sampling infonnation. description of the materials recovered, approximate depths of boundaries between soil and rock strata and groundwater data. The log represents conditions specifically at the location and time the boring was made. The boundaries betWeen different soU strata are indicated at specific depths; however, these depths are in fact approximate and dependent upon the frequency of sampling. The transition between soU strata is often gradual. Also, the N-values may not represent the actual hardness of rock fonnations due to numerous solution holes within the formation. If formation hardness is of critical concem for proposed site activities such as exeavation. supplemental evaluation through the performance of test pits andlor profile piling would be prudent, as appropriate. Water level readings are made at the times and under conditions stated on the boring logs. Water levels change with time, precipitation, canal levels, local weJJ drawdown and other factors. The borings must be interpreted by a Professional Engineer familiar with local soU conditions. LJ n LJ II LJ n l.J n u n LJ n LJ n! 10.

ANALYSIS AND RECOMMENDATIONS The geotechnical report is prepared primarily to aid in t design of site work and structural foundations. Although t: infonnation in the report is expected to be sufficient for the purposes, it is not intended to detennine 1be cost ' construction or to s1Bnd alone as a CODStruction specification. Report recommendations are based primarily on data from te . borings made at the locations shown on' the test boring report SoU variations may exist between borings and may n. become evident until construction. If variations are the noted, the geoteclmica1 engineer should be contacted so tIu field conditions can be examined and recommendatior. revised ifnecessary. The geotechnical report states our understanding as to the location, dimensions' and structural features proposed for the site.

CONSTRUCTION OBSERVATION Construction observation and testing is an important element of geotechnical services. The geotechnical engineer's field representative (G.E.F.R.) is the "owner's representative" observing the work of the contractor, perfonning tests and reporting data from such tests and observations. ne leoteclllllClI1 enllnlter's field rqrUltntfltlvtt dou not ITultct thtt contractor's constl'llt:tlon mltlllU, 1MIhot!s, opltrlltlou or personneL The a.B.F.R. does not interfere with the relationship between the owner and the contractor and, except as an observer, does not become. substitute owner on site. The G.E.F.R-is responsible for hislber safety, but has DO responsibiUty for the safety of other personnel at the site. The Q,B.F.R. is an important member of a team whose responsiblJity is to observe and test the work being done and report to the owner whether that work is being carried out in general confonnance with 'the plans and specifications.
