EXCAVATION, GRADING, AND FILL
The primary section dealing with excavation, grading, and fill placement in the International Building Code is Section 1804. Other sections of the International Building Code that deal with excavation, grading, and fill compaction are as follows: * Special inspections (Section 1704.7). Special inspections for grading and fill compaction (site soil inspections) as presented in the International Building Code are summarized in Table 18.1 of this book. * Site work (Section 3304.1). Excavation and fills are also discussed in Chapter 33 (Safeguards During Construction). The information in Section 3304.1 of the International Building Code has been summarized in Table 18.3 of this book. * Grading (Appendix J). Grading regulations are presented in Appendix J of the International Building Codeand will be briefly discussed in Sec. 18.3.3 of this book.
18.3.1. Excavation and Grading
For excavation and grading, the International Building Code states: Section 1804.1 Excavation near foundations. Excavation for any purpose shall not remove lateral support from any foundation without first underpinning or protecting the foundation against settlement or lateral translation. | Section 1804.2 Placement of backfill. The excavation outside the foundation shall be backfilled with soil that is free of organic material, construction debris, cobbles and boulders or with a controlled low-strength material (CLSM). The backfill shall be placed in lifts and compacted in a manner that does not damage the foundation or the waterproofing or dampproofing material. Exception: CLSM need not be compacted. | Section 1804.3 Site grading. The ground immediately adjacent to the foundation shall be sloped away from the building at a slope of not less than one unit vertical in 20 units horizontal (5-percent slope) for a minimum distance of 10 feet (3048 mm) measured perpendicular to the face of the wall. If physical obstructions or lot lines prohibit 10
