I H I I SECTION 1 I I I I I H I I SITE PREPARATION 1. EXCAVATION AND T 4BAN1CMENT A. Descrjption: This item shall consist of excavating, removing and satisfactorily disposing of all materials within the limits of the work required to construct the building pad in accordance with these specifications and in conformity with the elevations shown on the plans. All topsoil shall he removed throughout the building area and be carefully stock- piled on the premises as directed. Removal of subsurface material below topsoil will be required to sufficient depth to provide suitable material to insure compaction as specified in Paragraph 1 C (2) of the Specifications. Material for back fill shall he as specified under Paragraph 5, Section 2 - Building Excavation. In case the volume of the excavation exceeds that required to construct the embankment to the grades indicated any excess shall be. used to grade the areas to ultimate development, or wasted as directed. In case the volume of excavation is not sufficient for construction of the fill to the grades indicated, the deficiency shall be supplied by this Contractor from off the site, to meet requirements as set forth above. ' Be Classification: All materials excavated shall be defined as "Unclassified Excavation". Test borings have been made at points indicated on the plans and a log showing classi- fication of soils encountered are shown. "Unclassified Excavation" shall include all excavation performed under this item regardless of the material encountered. I I I I [I I Li Frozen condition of any of the different classified materials taken from excavation shall constitute no claim for higher, classification or for extra work on the part of the Contractor. C. Construction Methods: (1) General - The rough excavation shall be carried to such depth that sufficient material will he left above the designated grade to allow for compaction to this grade. Likewise, on embankments, sufficient material shall be placed above the designated grade to allow for compaction and settlement. Should the Contractor, through negligence or other fault, excavate below the designated lines, he shall replace such excavation with approved materials, in an approved manner and conditions, at his own expense.The Architect shall have complete control over the excavation, movinr, placing 4nd �}ii posi ion ofa l material, a d,shal determine the suitability of materials to be placed in embank- ments. All materials determined unsuitable shall he disposed of in waste areas or as directed. In general, the layer of topsoil shall not be used in fills or in subgrades but shall be handled and placed as directed and specified above. Li 1-1 SITE PREPARATION The Contractor shall inform and satisfy himself as to the ' character, quantity and distribution of all material to he excavated. No payment will be made for any excavation material which is used for purposes other than those designated. All ' spoil areas shall be leveled to a uniform line and sections and shall present a neat appearance before project acceptance. The surface elevation of spoil areas shall not extend above ' the surface elevation of adjacent or contiguous usable areas of the site. (2) Tests - Tests shall be made as directed by the ' Architect of the soil to determine its moisture content, den- sity and other characteristics so that directions can be formulated to insure compaction of not less than 95% to the ' maximum density at optimum moisture. Before any work is started, standard Proctor tests shall he made and as many tests as may be necessary during compaction of fills to insure this result shall be done by modified Proctor test procedures. The Contractor shall have these tests made by a laboratory approved by the Architect. Three (3) copies of each test ' report shall be sent to the Architect. (3) General Areas Compaction - General areas outside ' building pad which are filled are not to be compacted with special equipment. During construction of such filled areas, the Contractor shall route his equipment at all times, both when loaded and when empty, over the layers as they are placed and shall distribute the travel evenly over the entire area. Layers shall generally be not more than R" thick. I I Embankment of the building areas to be compacted in accor- dance with Paragraph 1 under this Section. Y If it is necessary in the prosecution of the work to interrupt existing surface drainage sewers, or underdrainage, conduits, utilities, or similar underground structures, or parts thereof, the Contractor shall be responsible for and shall take all necessary precautions to protect and preserve or provide temporary services for same. When such facilities are encountered, the Contractor shall notify the Architect who shall arrange for their removal if necessary. The Contractor shall, at his own expense, satisfactorily repair all damage to such facilities or structures which may result from any of his operations or from negligence during the period of the contract. (4) Excavation - Excavation shall he performed as speci- fied in Paragraph C (1) at such places as are indicated on the contract plans to the lines, grades, and elevation shown or as directed by the Architect, and shall be made in such a manner that the requirements for formation of embankment can he followed. All material encountered of whatever nature within the limits indicated shall be removed and disposed of as directed. During the process of excavation, the grade shall he maintained in such condition that it will be well drained at all times. L 1-2 ' SITE PREPARATION ' when directed, temporary drains and drainage ditches shall he installed to intercept or divert surface water which may affect the prosecution or condition of the work. The excavation material shall be handled in such a manner as to allow..the selected. material to be properly placed in the embankment and in the capping of subgrades. ' If, at the time of excavation, it is not possible to place any material in its proper section of the permanent construction, ' it shall be stock -piled in approved areas for later uses., (here rock, shale, clay, hardpan or other material unsat'is- ' factory -for subgrade is encountered, it shall be excavated to a depth -.of at least twelve (12) inches, or such greater depth as the Architect may direct, below the contemplated surface of the subgrade. All material to he so excavated shall be paid ' for at the contract unit price per cubic yard for "Unclassified Excavation". The portion so excavated shall be refilled with suitable selected material as specified, obtained from the grading ' operations if intended for use outside building, for interior . use of material as specified and thoroughly compacted by rolling as specified. The necessary refilling will constitute a part of the embankment. Tht contractor shall make the distribution as indicated on the planso' and the widening or narrowing of the section, raising ' or lowering of the grade to avoid haul will not he permitted. The right is reserved to make minor adjustments or revisions in lines or grades if found necessary as the work progresses, ' due to discrepancies or in order to obtain satisfactory construc- tion. (5) Ditch Excavation - Ditch excavation shall consist of ' excavating for drainage ditches such as intercepting inlet, outlet, off take, temporary levee construction, as may he required. The work shall be performed in the proper sequence with the ' other construction. The location of all ditches or levees will be established on the ground. All satisfactory material shall be placed in fills; unsatisfactory material, waste or ' surplus material shall he disposed of as directed. (6) Stripping - All vegetation such as brush, heavy sod, heavy growth of grass, decayed vegetation matter, rubbish and any other unsuitable material within the area upon which embankment is to be placed shall be stripped or otherwise removed before the embankment is started, and in no case shall such objectionable material be allowed in or under the embank- ment. (7) Formation of Building Pad - Building pad shall be ' formed of materials placed in successive horizontal layers of not more than eight (8) inches in loose depth for the full width of the cross section. See Paragraph 4, Section 2 for material to be used to construct building pad. ' 1-3 ' SITE PREPARATION The grading operations shall be so conducted and the ' material shall be placed so as to produce a suitable soil structure. All materials entering the embankment shall be spread in successive layers as specified. IThe operations on earth work shall he suspended at any time when satisfactory results cannot be obtained on account of rain, ' freezing weather, or other such unsatisfactory conditions of the field. At all times the Contractor shall drag, blade or slope the embankment to provide proper surface drainage. During construction of the embankment, the Contractor shall route his equipment at all times, both when loaded and when empty, over the layers as they are placed and shall distri- ' bute the travel evenly over the entire width of the embankment. In the construction of embankment, starting layers shall be ' placed in the deepest portion of the fill and as placement pro- gresses, layers shall be constructed approximately parallel to the finished grade lines. Frozen material shall not he placed in the embankment nor shall embankment be placed upon frozen material. ' The Contractor shall be responsible for the stability of all embankments made under the contract and shall replace any portion which, in the opinion of the Architect, has become displaced due to carelessness or negligence on the part of the 'Contractor.

' Elevations and grade lines marked on the drawings indicate the heights in relation to a datum point noted on drawings. ' Under no circumstances shall excavated material be left, even temporarily, where it will interfere with the Owner's or other contractors' operations. ' Excavation shall be made outside of walls required to allow for inspection, placing and removal of forms and all trenches shall be left open until all work has been inspected and approved by the Architect. Pits containing any kind of loose material under foundations ' shall be dug out to solid bottom unless otherwise directed. Trenches for lowest sections of concrete footings and founda- tions laid on the ground shall be excavated exact size of same where possible. The bottom o€ all excavations for foundations shall be leveled off at exact depths required and all founda- tions shall be placed on undisturbed earth; if filling is required under foundations, it shall be done with approved ' concrete as directed. Earth filling under foundations will not be accepted. Cost of extra work and material required by careless, excavating, beyond the depths shown on the drawing, shall be. borne by the Contractor. Upon completion of the excavation and before footings are placed, the Architect shall be given due notice so that he may ' inspect the excavations in which foundations and footings are to be placed. Excavation shall be sufficiently made so that no work ' rests on soil which is not capable of the soil pressure of 4,000 lbs. per sq. ft. If the Contractor is in doubt of ,such work, he shall ask for further instruction from the Architect ' and failing to do this, he shall be responsible for any damage to the building due to settlement. Li ' 2-1 ' BUILDING EXCAVATION Excavation for work beyond the dimensions shown on draw- ' ings, if required, by nature of the soil or by existing condi- tions not indicated on drawings, will be paid for as an extra but the price per cubic foot must be agreed upon before the work is started. All old sewers, piping, etc., encountered by this Contractor ' shall he properly taken care of, and where directed by the Architect, shall be removed and the ends plugged up tight. Any active sewers or pipes encountered shall be properly shored and protected. This work shall be done by additional allowance in accordance with unit prices agreed upon before the work is started.

' B. Sash and Frame Preparation and Acceptance - Inspect all frames and surrounds to be glazed under this section and notify the Architect of any defects, improper materials or workmanship or other conditions which will affect satisfactory installation of glass. Do not proceed with glazing until such conditions have been corrected. Absence of notification, or the beginning of glazing will indicate acceptance of all pre- viously placed related work executed by other trades; later claims of defects in such work will not relieve the glazier ' from responsibility to produce satisfactory work. The follow- ing work will be executed by other trades but before starting glazing work, the glazier shall verify compliance with the ' requirements listed. 1) That frames are firmly anchored in proper position, plumb and square within 1/8" of nominal dimensions on approved shop drawings. 2) That all rivet, screw, bolt or nail heads, welding fillets and other projections are removed from glazing rabbets to provide the specified clearance. 3) That all corners and fabrication intersections are sealed and frames are weather tight. 4) That rabbets at sills weep to outside and all rabbets are of sufficient depth and width to receive the glass and provide the required overlap of the glass. C. Preparation of Glass and Rabbets - Clean the sealing surfaces at perimeter of glass and the sealing surfaces of rabbets and stop beads before applying any glazing compound, tape, sealant or gaskets. use only the approved solvents and cleaning agents recommended by the compound manufacturer. D. Positioning Glass - Center in glazing rabbet to main- ' tain ceentereddpositionces at perimeter on all four of glass in rabbet and provide d the Niain- required sealer thickness 1/8" minimum on both sides of glass. ' Whenever glass dimensions are larger than 50 united inches, provide setting blocks at the sill and spacer shims on all four sides; locate setting blocks one -quarter way in from each end of glass. ' 18-4 ' GLASS SPECIFICATIONS ' E. Stop Bead Glazing - Using Glazing Compound - Except where other materials or methods are specified hereinafter, use putty for bedding glass in wood frames and use elastic glazing compound for bedding glass in metal frames. Apply as follows: 1) Apply ample back putty or compound to rabbet so that ' it will ooze out when pressing glass into position and com- pletely cover glass in rabbet. Place setting blocks and spacer shims as required. Press glass into position. ' 2) Secure glass in place by the application of stop beads. Bed stop beads against glass and bottom of rabbet with compound leaving proper thickness between glass and stop ' beads. Secure stop beads in place with suitable fastenings.

SCOPE A. The work covered by this section of the specifications ' consists of furnishing all plant, labor, equipment, appliances and materials and in performing all operations in connection with the construction of exposed aggregate finish Portland cement concrete sidewalks and surfaces, complete, in strict accordance with this section of the specifications and the applicable drawings, and subject to the terms and conditions of the contract. All exterior horizontal concrete surfaces except freight dock shall be exposed aggregate finish. 2. CONCRETE ' A. Concrete and the equipment, workmanship and materials therefore shall conform to the applicable requirements of the Structural Concrete Section of these specifications. Concrete ' shall be Class A. The maximum size of aggregate shall be 1-1/2". Concrete shall have a slump of not less than 2 and. more than 5 inches. ' 3. SUBGRADE PREPARATION A. The subgrade shall be constructed true to grade and cross section as shown on the drawings. The subgrade shall be thoroughly watered and rolled or hand -tamped until hard and solid beZore placing the concrete. Any soft or spongy material shall be'removed to a depth of not less than 40 below subgrade elevation, and replaced with earth, sand or gravel of a quality that will compact when moistened. This material shall then be rolled or tamped until a firm and solid foundation is obtained. Rollers Shall be hand rollers or small power rollers suitable for sidewalk construction. The completed subgrade shall be tested for grade and cross section with a template extending the full depth of the sidewalk and supported between side forms. The subgrade and forms shall be thoroughly watered in advance of placing the concrete. B. In cold weather, the subgrade shall be so treated, protected and prepared as to produce and provide a satisfactory ' subgrade. entirely free from frost when the concrete is deposited.. 5. FORMS Forms shall be of wood or metal, straight, free from warp, of sufficient strength to resist springing during construction, ' and of a height equal to the full depth of the finished side- walk. Wood forms shall be 2" surfaces plank, metal forms shall be of approved sections with a flat top surface. Forms shall i ' 24-1 ' EXPOSED AGGREGATE CONCRETE SIDEWALKS 6 SURFACES be set with the upper edge true to. line and grade and shall be held rigidly in place by stakes placed on the outside of t forms and set flush with the top edge of the form. Side forms shall not be removed less than 12 hours after the finishing has been completed. 6. CONCRETE PLACEMENT AND FINISHING A. Concrete shall be placed in the forms in a layer of - such thickness that when compacted and finished the sidewalk will be of the thickness shown on the drawings. Sidewalks. shall be continuous between expansion joints. After the concrete ' has been placed between side forms, a strike off guided by.;the : side fo4sshall be used to bring the surface to the proper;,:,. section°",, lie compacted. The concrete shall then be tamped H. • with a,4 d&ir consisting of parallel metal bars until a thin .:'•; layer df:mortar has been brought to surface and given a fina!1' tamping,b i;tb a light tamper consisting of a wire mesh having ' square Cp@nings not less than 1/8" nor more than 1/4" in size;.,; B. The surface shall be finished to grade and cross , section with a wooden float at least 10 feet in length, 6to 8 .. ' inches in width, and at least 1 inch in thickness, with handles at each end for longitudinally floating along the surface. Immediately after the surface of the concrete has been ' leveled and surface water has disappeared, aggregate shall -be spread uniformly over the surface to provide complete coverage to the depth of a single stone. I. The aggregate shall be brown colored washed gravel as approved by Architect. The spread of selected aggregate shall be embedded into the surface by light tamping and the ' surface shall be floated until the embedded stone is fully coated with mortar and the surface has been brought to a true plane. Exposure of the aggregate shall start after the matrix ' has hardened sufficiently to prevent dislodgement of the aggre- gate. Water in copious quantities but without force, shall be allowed, to flow over the surface of the concrete while the matrix encasing the selected aggregate is removed by brushing with a fine bristle brush. This operation shall continue until the selected aggregate is uniformly exposed but not dislodged.. An approved chemical retarder sprayed onto the freshly floated surface may be used to extend the working time for exposure of aggregate, ' 7. JOINTS Transverse joints shall be installed at all sidewalk returns and opposite expansion joints in adjacent curb and elsewhere as directed by Architect in approximately 10 -foot intervals each direction. Joints shall be 1 x 4 redwood in full length installed vertically with top edge flush with concrete. 24-2 I EXPOSED AGGREGATE CONCRETE SIDEWALKS & SURFACES 1 8. CURING AND PROTECTION C I I I I I I H I I L L n G I A. Curing - Immediately after the finishing operations, the exposed surface shall be cured by the blanketing method, mat• method, or impervious -paper method, or by the membrane curing method, as the Contractor may elect. 1) Blanketing Method - The entire exposed surface shall be covered with a blanket of sand not less than 2" thick. Immediately after placing, the blanketing shall be watered and kept saturated for not less than 7 days. 2) Mat Method - The entire exposed surface shall be covered with cotton mats conforming to Federal Specification DDD-M-148 or with two or more layers of burlap conforming to Federal Specification CCC-B-811 having a combined weight of 14 ounces or more per square yard when dry.• Immediately after placing, the mat shall be thoroughly wet with water and kept in a saturated condition for 7 days. 3) Impervious -Paper Method - The entire exposed surface shall be covered with waterproof paper conforming to Federal Specification UU-P-264, laid directly upon the concrete. Transverse joints in the sheets shall overlap 12". Sheets shall be securely at least 18" wider than the walk. The sheets shall be securely weighted down by placing a bank of moist earth on the edges of the sheets just outside the forms and over the transverse laps of the sheet to form a closed joint. The paper shall be allowed to remain in place for not less than 7 days. Should the paper be broken or damaged during curing, the broken or damaged portions shall be immediately repaired with new paper. 4a Membrane -Curing Method - The entire exposed surfaces shall be covered with a pigmented membrane -forming curing compound conforming to Corps of Engineers Specification CRD-C-300. The curing compound shall be applied in two coats by hand operated pressure sprayers at a coverage of approximately 200. square feet per gallon for both coats. The second coat shall be applied in a direction approximately at right angles to the direction of application of the first coat. The compound shall form a uniform, continuous, coherent film that will not check, crack, or peel and shall be free from pinholes or other imperfections. Concrete surfaces which are subjected to heavy rainfall within 3 hours after the curing compound has been applied shall be resprayed by the method and at the coverage I 24-3 I] Ti I L I I I I J I r I I I I EXPOSED AGGREGATE CONCRETE SIDEWALKS El SURFACES above, at no additional cost to the Owner. All expansion and contact joint openings shall be sealed at the top by inserting moistened paper or fiber rope or covering with strips of waterproof paper prior to application of the curing compound, in a manner to prevent the curing compound entering the joint. Concrete surfaces which membrane -curing compounds have been applied to shall be adequately protected for 7 days from pedestrian and vehicular traffic and from any other action which might disrupt the continuity of the membrane. Any area covered with curing compound and damaged by subsequent construction operations within the 7 -day curing period shall be resprayed at no additional expense to the Owner. B. Protection - After the concrete has been cured, all debris shall be removed, and the area adjacent to the sidewalk shall be:backfilled, graded and compacted in a satisfactory manner in accordance with the lines and grades shown on the drawings.: The completed sidewalk shall be protected from damage until accepted. The Contractor shall repair, at his own expense, all concrete damaged during construction. The repair shall be made by removing and replacing the defective sidewalks between the nearest joints.

Wherever pipes are placed so that they will be ultimately concealed, these tests shall be conducted and the absolute tight- ness of each piping system shall be demonstrated, before that system is concealed and made inaccessible. The procedure of these tests shall consist of subjecting a piping system to a hydrosta- tic pressure of one hundred and fifty pounds (1500 per square inch gauge for a period of not less than eight (8) hours. During this test period, all leaks in pipe, fittings and accessories, in the particular piping system which is being tested, shall be stop- ped and the hydrostatic test shall again be applied. This proce- dure shall be repeated until for an entire eight (8) hour period no leaks can be found while the system being tested is subjected to the pressure mentioned above. I 25-17 I I I I I I I I I I I L. J I I I (b) After the vertical lines of soil pipe, waste, down- spouts and other parts of the sanitary systems have been set, all outlets shall temporarily be "plugged up". The pipes shall be filled with water testing the system in sections. If, after twenty- four (24) hours, the level of the water has been lowered by leakage, the leaks must be found and stopped by the Contractor, and the water level shall again be raised and the test repeated, until, after a twenty-four (24) hour retention period, there shall be no percep- tible lowering of the water level of the system being tested. The testing of vertical risers, branches, mains, etc. shall be made under the supervision of, and shall be approved by, the local Plumbing In- spector, and the entire. system shall meet all requirements of the Local and State Plumbing and Sewer Regulations. The Contractor shall, after all tests have been completed, provide for the Owner, without ex- tra cost, a certificate which shall certify that the plumbing sys- tems of the building have been inspected and approved by the Plumbing Inspector and that all fees therefor have been paid by the Contractor. After testing operations are complete, all soil and waste lines shall be thoroughly cleaned with an approved type wire sewer brush. (c) All gas piping systems shall be very carefully test- ed by the Contractor. These piping systems shall first be sub- jected to a pneumatic pressure test of one hundred pounds (100#) per square inch. While the systems are subjected to this air pres- sure, all welded joints and threaded joints shall have a soapy wa- ter solution applied for the purpose of detecting minute, as well as larger, leaks. If leaks are found in the welded line they shall be repaired by clipping and rewelding operations. Alternate test- ing and rewelding operations shall be repeated until the gas piping systems are absolutely tight. If leaks occur in the case of thread- ed joints, such leaks may be.eliminated by replacing the fittings or properly tightening. them. The entire gas piping system shall be subjected to a pneumatic test pressure of one hundred pounds (100#) per square inch for a period of twenty-four (24) hours and demon- strated to be absolutely tight. (d) Prior to operation, all piping systems shall be tho- roughly flushed out. The steam and condensate piping systems shall be operated for a period, of eight (8) hours with the thermostatic elements of all traps removed and with all condensate wasted. (e) All water systems shall be properly balanced (f) Each and every phase of the air conditioning, heat- ing and ventilating systems shall be operated separately, or in conjunction one with the other, for a sufficient period of time to demonstrate to the satisfaction of the Architect the ability of the olant to meet the capacity and performance reouirements while maintaining design conditions in accordance with the true intent and purpose of these specifications.
