Remove such shoring and bracing when no longer required, except as otherwise approved.
REMOVAL OF UNSUITABLE SOILS REMOVE ORGANICALLY CONTAMINATED soil from the building and parking area. REMOVE UNSUITABLE BEARING MATERIAL in encountered in the foundation excavations. 1. REPLACE WITH MDOT class 2 sand suitable or on-site materials, acceptable to the testing agency. Or extend footings to bear on underlying higher strength soils, as directed by the Soils Engineer. FLOOR SLAB ON GRADE AND PAVING: Prior to placing concrete floors or pavements, and before fill is placed, remove excessively organic, loose or obviously compressed materials.
EXCAVATION OF POOR SOILS PRIOR TO PLACING ANY NEW FILL: Remove all topsoil, organic soils, frozen materials, existing uncontrolled fill, and obviously compressible soils. Consult with Testing Agency: 1. MAINTAIN EXCAVATIONS in a relatively dry and workable condition so that moisture content of backfill can be controlled. 2. IF SUBGRADE IS SOFT CLAYS: They must be removed or disced and harrowed to aerate and dry the soils. Subsequently compact these to same minimum density as the new fill. GROUND WATER CONTROL: The contractor shall provide, maintain and operate equipment, trenches and sumps and/or wellpoints to keep excavations free of water at all times. 1. PROVIDE PITS, TRENCHES, AND PUMPS; as required to reduce the water table in isolated area. 2. DO NOT PERMIT soil solids to be removed together with water. 3. LOCATE DISCHARGE at a suitable distance from the excavation.

PROOF COMPACTION AFTER CLEARING, GRUBBING, topsoil stripping, and removal of unsuitable soils, and fill soils and before placing new fill, have the Testing Agency observe the stripped area, to aid in locating unsuitable materials. Remove such materials. Then thoroughly proofroll the resulting subgrade with a heavy rubber-tired construction vehicle, such as a loaded dump truck Further compact or remove loose or soft areas detected by proofrolling and replace such areas with an approved engineered fill, of either granular or cohesive soil. 1. PROOFROLL THE ENTIRE building area, drives, and parking areas. Compact subgrade in cut areas to produce a compaction equal to that of the filled areas. Surfaces to be filled shall also be compacted before placing fill. 2. SUBGRADE shall be proof compacted until it offers a relatively unyielding surface. Proper equipment shall be used. If this proof compaction causes water to move to the surface or if it causes the subgrade to "pump" or to become unstable, the proof compacting should be stopped and the soils engineer consulted. 3. COMPACTING EQUIPMENT: Shall consist of a heavy vibratory roller of not less than 20 ton rate weight. The roller should make a minimum of 4 passes in each of two perpendicular directions covering the proposed development area. Any areas that exhibit excessive pumping and yielding during this operation should be stabilized by discing aeration and recompaction if weather conditions permit, or by the removal of the yielding soils and their replacement with properly compacted fill. 4. OPERATE THE TEST ROLLER in a systematic manner so that a record may be readily kept of the area tested. 5. REMOVE ALL LOOSE or soft subgrade materials, as indicated by excessive deflection under proof rolling operation, and replace with Class 2 Granular Material and compact to 95% maximum density. 6. MOISTURE CONTENT: Some clay soils near the surface may be difficult to compact, especially if performed in a wet spring or fall. If needed, disc and aerate the clay subgrade soils during earth work operations to achieve desired compaction. It may also be needed to stabilize subgrade at areas to be filled.
FILLING GENERAL: Begin filling in the deepest areas and proceed approximately parallel to finish grade. Spread, place and compact each lift to achieve layers of uniform thickness. Place no fill on subgrade or previous fill surfaces where free water is standing, or where surfaces have not been tested and approved. Take care to prevent overloading the structure or damaging drainage systems. Place and compact fill materials as specified further below. 1. DO NOT PLACE FILL ON FROZEN SUBGRADE. 2. DO NOT PLACE FILL MATERIAL THAT IS FROZEN. PREPARATIONS PRIOR TO BACKFILLING: Backfill excavations promptly as the work permits, but not until the following: 1. APPROVAL of construction below finish grade. 2. INSPECTION, TESTING, approval, and recording location of underground utilities. 3. REMOVAL OF CONCRETE formwork. 4. REMOVAL OF SHORING and bracing. 5. REMOVAL OF TRASH and debris. PLACING BACKFILL MATERIAL: 1. SCHEDULE BACKFILLING to expedite construction progress and to maintain positive site drainage. Backfill after grade beams and column foundations and foundation walls have been completed and attained proper strength. Backfill both sides of grade beams and foundation walls at the same time. Backfill in manner to prevent excessive pressure against or damage (including hydraulic) to adjacent work. Any resultant damage shall be corrected at the Contractor's expense. 2. FILL should be constructed by placing loose and uniformly thick, for the full width of the lift, layers of not more than nine (9) inches depth before compaction. Materials shall be thoroughly and uniformly moistened or dried to achieve uniform and optimum compaction. 3. WHERE ON-SITE MATERIALS are used, those soils which contain excessive amounts of silt or water, and any predominantly cohesive soil consisting of silt or clay should be discarded as it will be virtually impossible to compact them to the required density. 4. NEW FILL if it is brought to the site, it should preferably consist of a granular soil, free from organic or other deleterious materials.
EHRESMAN ARCHITECTS 02 200 – EARTHWORK DETROIT ZOOLOGICAL SOCIETY PROJECT NO.: 4818 BELLE ISLE NATURE CENTER – ANIMAL HABITAT IMPROVEMENTS PAGE 5
PLACING FILL MATERIAL 1. UPPER PORTION to a maximum depth of 2 inches of the subgrade should be disced and harrowed if it is in a wet condition. No fill shall be placed upon wet ground or where there is standing water. No frozen material shall be used for fill and no fill shall be placed on frozen ground. 2. PLACE SELECT FILL in layers not exceeding nine inches (9”) of loose thickness and thoroughly compacted prior to the placing of the next layer. 3. COMPACT EACH LAYER as soon as possible after placing. Any compacted ruts in the layer, due to traveling or hauling equipment, shall be harrowed, if required, so that the compacting equipment shall operate over a uniform layer. 4. PITCH THE SURFACE of the fill slightly to promote surface run-off of rainfall. 5. AT COMPLETION of each workday, the surface of the fill should be smoothed and sloped to minimize infiltration and absorption of rainwater.
COMPACTION COMPACTION: Compact backfill material at approximately the optimum moisture content to not less than the required percentage maximum density as determined by the Modified Proctor Test by compacting equipment suitable for the backfill material being compacted and the location of the work relative to other construction, and capable of obtaining the required percentage maximum density throughout the entire layer of soil material. 1. MOISTURE CONTROL: Prior to compaction, add or reduce the moisture content of the backfill material as determined by the Modified Proctor Test within limits; from 3% below optimum to that point above optimum where the required density can be reached. Add moisture by equipment capable of adding measured amounts of water to the backfill material. Reduce moisture content by harrowing or discing and letting dry. Do not water flood backfill material in place. Suspend compaction operations when weather conditions or other unsatisfactory conditions make it impossible to obtain satisfactory results. PREPARATION OF EXPOSED SUBGRADE UNDER SLABS-ON-GROUND: Before commencing backfilling compact subgrade surface in areas to receive concrete slabs-on-ground to not less than 90 percent maximum density for fine-grained and not less than 95 percent maximum density for coarse-grained soils and to a minimum depth of 12 inches or to such greater depth as required to permit the specified compaction of the backfill material. 1.

EXTERIOR PERIMETER OF BUILDING and Under Concrete Walks and Curbs: Backfill excavations with Satisfactory Excavated Material or Borrow Material or Class 2 Granular Material to underside of concrete construction and compact to 95 percent maximum dry density. 1. EXCAVATED OR BORROW MATERIAL: must be tested equal to specified granular material. AREAS TO BE LANDSCAPED: Fill low areas under areas to be grassed within the contract limits with Satisfactory Excavated Material or Borrow Material to 4" below required finish grade for grassed areas, and compact to same density as adjacent soil material, but not less than 80 percent maximum density. Protect subgrade from erosion by mulching.
TOPSOIL AND FINISH GRADING AREAS TO BE LANDSCAPED: Fill low areas with satisfactory excavated material and compact to some density as adjacent soil material, but not less than 80% maximum dry density. 1. PROTECT SUBGRADE from erosion by mulching. 2. TOP OF ROUGH GRADE: 4” below finish grade. 3. FINISH GRADE: To establish elevations and to slope away from building. Minimum 6” in 10 feet. 4.
