AlI injection pipe installations and grouting operations shall be performed in the presence i <br /> of the Geotechnical Engineer's representative. The Geotechnical Engineer or his or her � <br /> representative shall assume responsibility for verifying the quantity of grout pumped,intervals of i <br /> grouting and deciding if additional or less grout is necessary. <br /> I <br /> Compliance � <br /> The Geotechnical Engi.neer or his or her representative may stop the grouting operation at any time <br /> if,in his or her judgment,the operation does not comply with these specifications or the work is � <br /> unsuitable.
