Specifically, our observations indicate the following features are in general accordance with floor slab recommendations in our Geotechnical the subdivision on September 12, 1994 (Project No. 20945121): walls, 2) positive separations and/or isolation joints between columns and plumbing and 3) contraction joints in the slab.

Four inch diameter, perforated PVC pipe was observed around the exterior perimeter of the basement foundation. The drainage pipe exhibited positive drainage toward the sump in the southeast corner of the basement. Maximum 1 Yrinch washed aggregate was observed above the pipe. The gravel extended three inches above the pipe at the time of our first site visit and 12 inches above the pipe at the time of our second site visit. Layers of filter fabric were observed beneath the pipe and above the gravel. In addition, the void forms were observed to be in good condition at the time of our site visit.

Box 503 Fort Collins, Colorado 80521-0503 (970)484-0359 Fax: (970)484-0454 October 5, 1998 Melody Homes 11031 Sheridan Boulevard Westminster, Colorado 80020 Re: Lot 96, Ridgewood Hills PUD, First Filing 618 Holyoke Court Fort Collins, Colorado Project No. 20975113 Gentlemen: On September 24, 1998, Terracon observed the foundation excavation for the referenced project. The exposed soil at the upper level is sandy lean clay. Sandy lean clay over sandstone bedrock was observed at the lower foundation level. These materials are similar to materials described in our Geotechnical Engineering Report prepared for the subdivision (see Project No. 20945121 dated September 12, 1994). Based on our observations, it is recommended that the structure be supported by a spread footing foundation system designed in accordance with the recommendations set forth in the geotechnical engineering report. Since bedrock was encountered within 2 feet of the basement foundation level, it is our opinion a dewatering system should be placed around the basement foundation. Specifically, a Type A perimeter drain is recommended at this site. Sincerely, TERRACON ���p O REGIST �• p .'sciio• F C+, PP• F2F�% Jy m; isa R.
