Common use of SITE PREPARTION Clause in Contracts

SITE PREPARTION. A. Clean and grub all surface vegetation, excavating and removing all topsoil a minimum of eight inches from the building structure area plus a six foot margin from the exterior foundation lines. Remove all tree stumps, concentration of roots and other deleterious materials. Stockpile usable topsoil for landscaped areas as directed by the Engineer. B. Dispose of unsuitable topsoil and excavated material from the site. C. If unsuitable bearing soils, peat or muck are encountered, contact Engineer for further direction. D. Structures excavations below water table shall require a dewatering system to prepare the base of the excavation. The dewatering system shall remove water approximately two feet to three feet below the bottom of the excavation. E. Compact exposed stripped and excavated surface for buildings by means of an approved vibratory roller until eight passes have been made and a soil density of 98 percent of maximum modified Xxxxxxx Density has been achieved twelve inches below the exposed compacted surface. Test compaction as specified. Add water if necessary to bring up moisture to optimum levels. F. If ground water is within twelve to twenty-four inches from the ground surface, it would be necessary to lower the ground water to permit effective compaction. Lowering of the ground water may be accomplished by excavating four to five feet deep ditches around the construction area and pumping from sumps in the bottom of ditches. Contact testing lab to develop feasible procedures for dewatering.
