1. All building pad preparation shall follow the recommendations of the geotechnical report (uno).
2. Foundation design is based upon the removal of unsuitable material and replacement with engineered fill per the geotechnical report.
3. All trees, brush, roots, topsoil, rubble, organically contaminated or otherwise objectionable materials encountered are to be removed from structural areas of the site per the geotechnical report.
4. Subgrade sectors which will exist in cut and those which are to support fill structures are to be proof rolled. Areas exhibiting instability are to be undercut and back filled on a lift-by-lift basis with each lift carefully compacted.
5. If unstable subgrade sectors cannot be stabilized by excavation and recompaction, then crushed stone or similar coarse aggregate materials shall be rolled into the subgrade until a firm subgrade reaction is achieved.
6. The geotechnical engineer shall determine on site or off site imported material that can be used for engineered fill. All fill material shall be approved by the geotechnical engineer.
7. The proposed engineered fill materials are to be placed in lifts not exceeding eight (8) inches in loose measured thickness. Each lift is to be compacted as follows:
A. Slab on grade: Minimum of 95% maximum density by ASTM D698.
B. Footings bearing on fill: Minimum of 98% maximum density by ASTM D698.
8. The earthwork program shall be conducted under the supervision of a soils testing laboratory. The in-place densities achieved are to be verified by tests.
Building Pad Preparation
1. The contractor shall familiarize themselves with the survey and the geotechnical investigation report before starting construction. All foundation work shall be in accordance with the recommendations of the geotechnical report by S & ME dated 4/2/2020 except where noted otherwise on drawings or specifications.
2. A soils testing laboratory shall be retained by the owner to provide construction review to insure conformance with the construction documents during the excavation, back fill, and foundation phases of the project.
3. The soils testing laboratory shall:
• Discuss with the engineer the design intent of the construction documents and the testing procedures used to ensure conformance with the construction documents before construction begins.
• Inform the engineer of any variance in these procedures.
4. It shall be the responsibility of the soils testing laboratory to:
• Determine topsoil and excavation stripping depth;
• Inspect all subsoil exposed during stripping, site grading, and excavation operations;
• Approve fill materials, perform density tests of fills to insure placement per specification requirements;
• Inspect foundation bearing surfaces.
5. Foundation design is based on 2,000 psf bearing pressure on firm, undisturbed soil.
6. Top of footing elevations, footing steps and thickness of footings are shown on the drawings and are based upon the information from the geotechnical report and the civil drawings available at the time of design. The top and bottom of footing may vary depending on the conditions encountered at the site.
Frost depth shall be maintained and coordinated with final grading and location of footing steps. If proper foundation bearing is found to be deeper than that shown on the drawings then foundations shall be thickened maintaining the top of footing elevation to assure proper foundation bearing. The contractor shall submit unit prices for such work and shall qualify the extent of work in the base bid. If top of footing elevations need to vary for final site conditions then the general contractor shall coordinate the effort of other trades.
7. Step footings, where required, at a ratio of one (1) vertical to two (2) horizontal with a maximum vertical step of 2'-0" unless noted otherwise.
8. Inundation and long term exposure of bearing surfaces, which will result in deterioration of bearing formations, shall be prevented. Footings shall be placed immediately following footing excavations and bearing surface inspection.
9. All fill materials shall be free of organic contaminations and other deleterious matter.
10. For back fill against retaining walls, footings, etc., place in 8" thick layers, with each lift compacted at near optimum moisture content, until a minimum in place density of 95% of the maximum density as determined by ASTM D698 is achieved.
11. All soil surrounding and under footings shall be protected from frost action and freezing during the course of construction.
12. Notify structural engineer of any unusual soil conditions that are in variance with the geotechnical report.
