All 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 /> Compliance I <br /> The Geotechnical Engineer or his or her representative may stop the grouting operation at any time i <br /> if, in his or her judgment,the operation does not comply with these specifications or the work is ' <br /> unsuitable. <br /> i <br /> Daily Records � <br /> The Geotechnical Engineer or his or her representative will malce aIl measurements of ground , <br /> heave or settlement,installed pipe lengths and grout quantities pumped.
