IMPORTANT INFORMATION ABOUTYOUR GFATECHIVICAL ENGINEERING REPORT More consvuction probiems are caused by site subsur- face conditions than any other factor. As troublesome as subsurface probiems can be, their frequency and extent have been lessened considerably in recent years. due in large measure to programs and publications of ASFE/ The Association of Engineering Firms Practicing in the Geosciences. The following suggestions and observations are offered to help you reduce the Qeotechnical-related delays. cost-overruns and other costly headaches that can oaur during a construction project. A GEOTECHIvi��AL ENGINEERING REPORT 1S BA.SED ON A UNIQUE SET OF PROJECT SPECIFIC FACTORS A geotechnical engineering report is based on a subsur- `ace exploretion plan designed to incorporate a unique set of project-specific (actors. These typically inciude: the generel nature of the structure involved. its size and configuration: the location of the structure on the site and its orientation; physical concomitants such as access roads. parking lots, and underground utilities. and the level of additional risk which ;he <:lient assumed by virtue of limitations imposed upon the exploratory program. To help avoid costly problems, consult the geotechnical engineer to determine how any (actors which change subsequent ro the date oF the report may affect its recommendations. Unless your consulting geotechnical engineer indicates otherwise. your grotechnical engineering report should not be used: • When the nawre of the proposed strucmre is changed, for example. if an o(fice building wil! be erected instead of a parking garage, or if a refriger- ated warehouse will be built instead of an unre- frigereted one: . when the size or configuration of the prouosed structure is altered; • when the location or orientation of the proposed struccure is modified: • when there is a change of ownership. or • for application to an adjacent site.

MOST GEOTECHNICAL "FINDINGS" ARE PROFESSlONAL ESTIMATES Site exploretion identi(ies actual subsurface conditions only at those points where samples are taken. when they are taken. Data derived through sampling and sub- sequent laboratory testing are extrapolated by geo- technical engineers who then rencier an opinion about overali subsurface conditions, the�r likely reaction to proposed construction activity. and appropriate founda- tion design. Even under optimal circumstances actual conditions may differ from those inferred to exist, because no geotechnical engineer, no matter how qualified, and no subsurface exploration program, no matter how comprehensive. can reveal what is hidden by earth, rock and time. The actual interface betweer� mate- rials may be far more gradual or abrupt than a report indicates. Actual conditions in areas not sampled may differ from predictions. Notfiinn can be done to prevent tFe ununticipated, but steps can be taken to help minimiu their impact. For this reason. mo5l exvrrienced owners rdain lheir geotechnicnl consuLants through the construction stage, to iden- tify variances, conduct additional tests which may be needed, and to recommend solutions to problems encountered on site. SUBSURFACE CONDITIONS CAN CHANGE Subsurface conditions may be nodiFied by constantly- changing natural forces. Because a geotechnical engi- neering report is based on conditions which er.isted at the time of subsurFace eaploration, construction decisions shnuld not br 6ased on a geotechnical engir�eering report whose adrquaiy may have heen aj(ected 6y time. Speak with the geo- technical consultant to learn if additional tests are advisable before construction starts. Construction operetions at or adjacent ro the site and natural events such as Floods, earthquakes or ground- water fluctuations may also affect subsurface conditions and, thus, the continuing adequacy of a geotechnical report. The geotechnical engineer should be kept apprised of any such events, and should be consulted to determine if additional tests are necessary.
