GenerA i The Contractor shall make such excavations as may be required for the conutruction to line, grade and extent indicated on the Plans of the building and other structures, roadways, utilities, vewers, drains and incidentals thereto. Water encountered in excavations shall be attended to by the Contractor who shall do all bailing, pumping and dowatering at his expense, so that foundations, Ovalle, pipe lines, and all other structures may be constructed "in the dry't. Earth from excavations shall be used to backfill around structure as required. Earth from excavation not required for baokfill shall be termed "surplus earth" and shall be removed by the Contractor. The surplus earth may be disposed of on the project site. Where structures, pavement, pipe lines, or fill are located at such elevations as to rest in or on the weathered organic topsoil, the area to receive their shall be stripped to such a depth as necessary to reach the inorganio subsoil consisting of clay, silt, sand, or a combination of these. Ba §lirgj ura Excayationj Excavation shall extend a sufficient distance from Ovalle and footings to allow for forma, installation of service, and for inspection, except where concrete for galls and footing is authorized or required to be deposited directly against excavated surfaeos. More the excavation is made below the elevations indicated on the drawings or directed by the Engineer Vtrough the fault of the Contractor, the exoava- Lion shall be restored to the groper elevation with lean concrete or other selected material, at the expense of the Contractor. In order that the Engineer may judge the adequacy of a proposed founda- tion, the Contractor, if requentod, shall make soundings to determine the character of the eubgrade materials, The maximum defith of such soundings will not be roquired to exceed five (51) feet below the proposed footing grade, It is the intent of thin provision that soundings shall be maade at the time the excavation in each foundation is approximately eompleite. The final elevation to which a foundation is to be constructed shall be as shoim on the drawings or as raised or lowered by written order from the Engineer when uuoh alterations are judged proper to satisfactorily comply t-ri.th the design requirements for the structure, Should it be found necessary to increase the depth of footings from that shown on the drawings, the necessary alterations in the details of the structure shall be ac- complished in a manner us directed by the Engineer, who shall have the right to substitute revised details if necessary. 103-1 When a structure is to rest on an excavated surface other than rook, special care shall be taken not to disturb the bottom of the excavation and removal of the last material required to reach foundation final grade shall not be performed until just before the footing is to be placed. All rook or other hard foundation material shall be freed from all loose material, oleaned, and out to a firm surface either level, std?ped, or serrated, as direoted by the Engineer. All seams shall be cleaned out and filled with concrete tit the time the footing is placed. Excavated material required to be used for back£ill may be deposited by the Contractor in storage piles at points convenient for rehandling the material during the k,yokfilling operations, The location of storage pile shall be subject to ~.;a, approval of the Engineer. Co Foiodation Beamas Trenches for foundation grade beams shall be out to such. width to permit the installction of side forms the full depth of beams: however, the bottom of trenches may act as the beam bottom where beam bottoma project below present grades, The Contractor has the option, however, of forming the bottom of all grade beams, regardless of whether the present grades are above or below beam bottoms. All excavations shall be left clean and free from loose material with a level bottom. U• Trench Engavations Trench excavation comprises excavation for all water lines, sewer lines, drain lines, miscellaneous lines, and appurtenances for the various typos of lines, All excavations shat l be made by open out. Banks of trenches shall be kept as nearly vertical as possible and, if re- quired, shall be properly sheeted and bruoed► Trenches shall be not lose than 12 inches nor more than 16 inches wider than the outride diameter of the pipe to be laid therein and shall be excavated true to line so that a clear spaco not less than 6 inches nor more than 8 inches in width is pro- vided on each side of the pipe. Bell holes shall be excavated to insure bell end type pipe resting for its entire length on the bottom of the trench. The bottoma of all trenches excavated for vitrified clay or concrete sewers or drains shall. be rounded so that at least one-fourth (1/4) the oiroum- feronoc of the pipes will root firmly on undisturbed soil, unless eonerete ormdle is required. Excavation for manholos and other accossorios shall be sufficient to leave at least 12 inches in the clear between the outer surfaces and tho excavation. Except at locations whore rook excavation forms the bottoms of the trenches, care shall be taken not to excavate below the required depths. Whore rook excavation is roquirod, the rook shall be excavated a minimum overdepth of 4 inches and backfilled to the required elevation vrith loose, moist earth, thoroughly tamped to the satisfaction of the Engineer, No pipe shall be laid in a trench in the presence of water, All water shall be removed from the trenches sufficiently ahead of the pipe placing operations to insure a dry, firm bed on which to place the pipes 103-2 and trench shall continue to be de watered until after the pipe has been placed and ,jointed. Removal of water may be accomplished by bailing, pumping or by other suitable means. E.

Where pipes, walks, or other construction is to be placed on or in the backfilled material, the baokfilling shall be dono in a thorough manner to preclude after-settlement. Haokfilling shall be brooght to a suitable elevation above natural ground or grade to provide for any antioN paced settlement and shrinkage of the baokfill, The Contractor shall use caution in placing the baokfill around atruotures to prevent any damage to there structures. Contractor shall secure the approval of the Lngineer prior to placing baokfill around any of the atruotures. C► Ba9kfil for1'renehest 1aokfill shall be oarefully performed to the original grade, and the original surface restored to the satisfaction of the Enginaer, or to the bottom of footings or slabs where the trenches are under other eonstruotion► In pipo trenches, after pipeu have been tested and approved, baokfill consisting of excavated materials, free from l.aree clods or stoned, or other objectionable material, shall be carefully do- posited in layers not to exceed six (G") inches in thickness on both sides of the pipe and each layer thoroughly and carefully compacted until an elevation one (11) foot above the top of the pine has been reaahod► 'rho remainder of the baokfill may be thrown in, moistened and thoroughly oompaoted by tamping, rolling, or othenrise. Whenever the trenches have not been ;properly filled or if settlement occurs, they shall be refilled, compacted, smoothed off and finally made to conform to the surface of the ground, Where trenches are under roadways, pipes, concrete slabs or floors, or other construction, the baokfill shall be as specified above except that the baokfill from one (11) foot above the top of the pipe to grade, 1033 to grade, or bottom of pipe to structure overlaying the trench, shall be deposited in layers not to exceed nine (91) inches in thickness, moistonod Lind compacted to a density equal to or greater than thc.t of the undisturbed material adjacent to the trench, Where indicated on the Plans, the backfill in trenohon rshall be of lean ooncrot,o, H.

Aeneralt The Contractor shall make such excavations as may be required for the construction to line, grade and extent indicated on the Plane or as may be required for the constructing of structures, installation of piping and incidentals therato. Excavations shall be dewatered so that all work may be performed in the "Dry". The Contractor, at his expense, shall do all bailing, pumping and dewatering as may be required. All water removed from trenches shall be conducted to natural drainage ways, drains or storm cowers in such a manner as to prevent damage to adjacent property or to the public. Pumps of ample capacity and in duplicate must be pro- vided to insure that once an excavation is nada dry, the water will be kept down until that part of the work under construction is completed. A, Classification of Excava ono All excavation shall be "unclassified" and involves the removing of all materials necessary to permit the carrying on and completing of the work. The Contractor, prior to sub- mitting a proposal, must satisfy himself as to the actual sub-surface conditions, No extra or separate payments for rook excavation will be made. Co Structural Excavations Excavation shall extend a sufficient distance from walls and footings to allow for forms, installation of servioes, and for inspection, except where concrete for walls and footings is authorized or required to be deposited directly against excavated sur- faces.

Fine Foundations The trench shall be excavated to an even grade to permit the installation of the pipe in such a manner that the full length of the pipe barrel in supported on the trench bottom. The entire foundation area in the bottom of all excavations shall be :firm, stable material, and material shall not be disturbed below required grade except as hereinafter described. Where the character of the foundation materials is such that a proper foundation cannot be obtained at the elevation indicated by tho plans, then, when directed by the Engineer in writing, the Contractor shall deepen the excavation to where a satisfactory foundation can be obtained, If the subgrade is soft, spongy, or disintegrated, the materials shall be removed until a firm, stable and uniform bearing is reached and the subgrade brought back to the required grade with material compacted in place or with granular or conoret., embedment material. If the unsatisfactory subgrade condition in due to the Contractor's failure to make a proper provision for adequate draitriage of excavations, the expense of replacing any unsatisfactory subgrade shall be borne by the Contractor, However, if in the opinion of the Engineer, the unsatis- factory subgrade oorAition is not the result of the failure of the Contractor to provide adequate drainage, bailing or pumping faoilitiea and the Engineer orders in writing that the Contractor make additional excavation and replace unsatisfactory subgrade mator•ial, then compensation will be made. 4. Crrrecting_Faulty Grades Any part of the trench excavated below grade shall be correcto d with approved material, thoroughly com- pacted. 5. Pipe Clearance in stacks Ledge rook, rook fragments, or un- yielding shale or marl shall be removed to provide a olearanoe of at least four (4) inches below all parts of the pipe, valves or fittings. Adequate clearance for properly Jointing pipe laid in rock trenches shall be provided at bell holes. 6.
