Notify other crafts to permit Installation of their work; cooperate with other trades In setting such work.. Moisten wood forms Immediately before placing concrete where form coatings are not used.

Coordinate the installation of joint materials and moisture barriers with placement of forms and reinforcing steel.

General: Comply with ACI 304 "Recommended Practice for Measuring, Mixing, Transporting, and Placing Concrete", and as herein specified.

Deposit concrete continuously or in layers of such thickness that no concrete will be placed on concrete which has hardened sufficiently to cause the formation of seams or planes of weakness. If a section cannot be placed continuously, provide construction Joints as herein specified. Deposit concrete as nearly as practicable to its final location to avoid segregation.

Placing Concrete in Forms: Deposit concrete In forms in horizontal layers not deeper than 24" and in a manner to avoid Inclined construction joints. Where placement consists of several layers, place each layer whlle preceding layer Is still plastic to avoid cold Joints.

Consolldate placed concrete by mechanical vibrating equipment supplemented by hand-spading, rodding or tamping. Use equipment and procedures for consolidation of concrete in accordance with ACI recommended practices.

Do not use vibrators to transport concrete inside forms. Insert and withdraw vibrators vertically at uniformly spaced locations not farther than vislble effectiveness of machine. Place vibrators to rapldly penetrate placed layer and at least 6 11 Into preceding layer. Do not insert vibrators into lower layers of concrete that have begun to set. At each Insertion limit duration of vibration to time necessary to consolidate concrete and complete embedment of reinforcement and other embedded Items without causing segregation of mix.

Placing Concrete Slabs: Deposit and consolidate concrete slabs In a continuous operation, within llmlts of construction jolnts1 until the placing of a panel or section is completed.

Consolidate concrete during placing operations so that concrete Is thoroughly worked around reinforcement and other embedded Items and Into corners.

Bring slab surfaces to correct level with straightedge and strikeoff. Use bull floats or darbies to smooth surface, free of humps or hollows. Do not disturb slab surfaces prior to beginning finishing operations.

Maintain reinforcing in proper position during concrete placement operations.

Cold Weather Placing: Protect concrete work from physical damage or reduced strength which could be caused by frost, freezing actions, or low temperatures, in compliance with ACI 306 and as herein specified.

When air temperature has fallen to or Is expected to fall below 40E F (4EC) uniformly heat water and aggregates before mixing to obtain a concrete mixture temperature of not less than 50EF (10EC) and not more than SOEF (27EC) at point of placement.

Do not use frozen materials or materials containing ice or snow. Do not place concrete on frozen subgrade or on subgrade containing frozen materials.

Do not use calcium chloride. salt and other materlals containing antifreeze agents or chemical accelerators, unless otherwise accepted in mix designs.

Hot Weather Placlng: When hot weather conditions exist that would serlously impair quallty and strength of concrete, place concrete In compliance with ACI 305 and as herein specified.

Cool Ingredients before mixing to maintain concrete temperature at time of placement below 90EF (32 C). Mixing water



may be chllled, or chopped ice may be used to control temperature provided water equivalent of ice is calculated to total amount of mixing water. Use of liquld nitrogen to cool concrete is Contractor's option.

Cool steel with water-soaked burlap if it becomes too hot, so that steel temperature wlll not exceed the ambient air temperature Immediately before embedment in concrete.

Fog spray forms, reinforcing steel and subgrade just before concrete is placed. Use water-reducing retarding admixture (Type D) when required by high temperatures, low humidity, or other adverse placing conditions.

Float Finish: Apply float finish to monollthlc slab surfaces to receive trowel finish and other finishes as hereinafter specified, and slab surfaces which are to be covered with membrane or elastic waterproofing, membrane or elastic roofing, or sand-bed terrazzo, and as otherwise indicated.

After screeding, consolidating, and leveling concrete slabs, do not work surface unt!I ready for floating. Begin floating when surface water has disappeared or when concrete has stiffened sufficiently to permit operation of power-driven floats, or both. Consolldate surface with power-driven floats or by handfloating if area is small or Inaccessible to power units. Check and level surface plane so that depressions between high spots do not exceed 5/16" under a 10' straightedge. Cut down high spots and fill low spots. Uniformly slope surfaces to drains. Immediately after leveling, refloat surface to a uniform, smooth, granular texture.

Trowel Finish: Apply trowel finish to monolithic slab surfaces to be exposed-to-view, and slab surfaces to be covered with resilient flooring, carpet, ceramic or quarry tlle, paint or other thinfilm finish coating system.

After floating, begin first trowel finish operation using power-driven trowel. Begin final trowellng when surface produces a ringing sound as trowel is moved over surface. Consolidate concrete surface by final hand-troweling operation, free of trowel marks, uniform in texture and appearance, and with a level surface plane so that depressions between high spots do not exceed 1/4" under a 10' stralghtedge. Grind smooth surface defects which would telegraph through applled floor covering system.

Whenever conditions will permit, in the opinion of the Engineer, the pipe lines shall be tested before the pipe joints are backfilled. All uncovered joints shall be examined during the tests and all visible leaks shall be entirely stopped. Joints which leak shall be re-made and re-tested until found to be satisfactory.

Water used for testing shall be reasonably clean and free from oil, silt, mud, sticks, vegetable matter, and other objectionable materials. All water required for testing shall be furnished by the Owner.

Corporation stops shall be provided at high places on the pipe line for expelling air from the line, except at the high points where air valves may be indicated on the plans. Also, one corporation stop shall be furnished and installed for each test pump location at no direct payment.

When a section of pipe line of a length deemed suitable by the Engineer is ready for testing, it shall be given the specified leakage test and, if defects are discovered, it shall be retested after replacement of all defective items found therein. On the water distribution system, where practicable, the test length preferably shall not exceed 2,000 feet, and it shall not exceed 4,000 feet unless specifically approved by the Engineer due to the location of valves or other pipe line conditions.

For each leakage test, the air shall be completely expelled from the section of pipe line to be tested, and the test shall be made at a hydrostatic pressure of not less than 150 psi for a duration of not less than four (4) hours, during which the leakage shall not exceed one (1) gallon per inch of nominal diameter per mile of pipe per hour. In all cases, the test period shall be of sufficient duration to permit proper examination of pipe joints and other items in the test section of pipe line.

8. BACKFILLING:

A. General: The backfilling process shall begin as soon as the pipe is properly installed and joints are complete.

Backfill shall be carefully placed in the trench and uniformly compacted around the pipe. The backfill material must not be placed faster than the workman can distribute and compact it. All voids or spaces caused by the removal of sheeting or bracing shall be carefully filled and compacted with properly shaped tools.

All backfill compaction operations shall be subject to the approval of the Engineer. The Engineer shall have the right to reject compaction methods and/or equipment, which do not produce satisfactory results.

The Contractor shall be responsible for the stability of all backfill made under the contract until one year after final acceptance of the work. The Contractor shall restore any backfill that fails and repair any pavement or other structures which may be damaged as a result of backfill failure at his own expense.

Where any sheeting or bracing is withdrawn as backfilling progresses, all voids or spaces left thereby shall be carefully and thoroughly filled and compacted with proper tools.

Material for backfill shall contain no rubble, trash, broken concrete, asphalt or other objectionable materials.

B. Bedding: Bedding below the pipe, if required, shall be as called for on the drawings or as provided for in the construction documents. Unless otherwise noted, sand bedding shall be included in the unit price per linear foot of the pipe. Unless otherwise noted, crushed stone (#610) bedding shall be paid for separately under maintenance stone by the ton or cubic yard in place based on haul tickets as listed in the contract documents.

C. Haunching: Hauching is the backfill operation from the bottom of the pipe to the springline of the pipe. Hauching shall be completed as soon as possible after the pipe has been installed. The hauching material shall be compacted sand placed carefully by hand in layers of no more than six inches at a time. The sand shall be tamped/rodded under the haunches and around the pipe up to the springline (centerline) of the pipe and out to the trench walls. Appropriate control should be exercised to avoid vertical and horizontal displacement of the pipe from proper alignment. Dumping earth from the bank, careless or unskilled ramming around the pipe or unequal haunching is not be allowed.

D. Initial Backfill: The initial backfill is from the springline to 12 inches above the top of the pipe. Initial backfill shall be compacted sand placed by hand in layers of no more than six inches at a time. Attention should be given to assure that no voids remain between the pipe, trench bottom, and sides of the trench. Again, appropriate control should be exercised to avoid vertical and horizontal displacement of the pipe from proper alignment. Dumping earth from the bank, careless or unskilled ramming around the pipe or unequal backfilling is not allowed.

E. Final Backfill: The remainder of the trench shall be backfilled and firmly compacted with approved power tampers, pneumatic, or other approved mechanical equipment. The



final backfill should be placed and spread in uniform layers in such a manner as to completely fill the trench with a uniformly dense backfill load on the pipe and avoid unfilled spaces in the backfill. Rolling equipment should not be used until a minimum of 18 inches of backfill material has been placed over the top of the pipe.

The final backfill material shall be the best of the excavated material, free of roots and debris, or select material, as called for on the drawings or as provided for in the construction documents.

Topsoil shall not be hauled away, but shall be saved and used to cap the backfill, where applicable.

a) Public Road Right-of-Way or Under an Improved Surface: When the new pipe is installed PY open cut method within public road right-of-way or under an improved surface (under proposed or existing hard surface pavement or improved aggregate surface), the final backfill shall be select fill uniformly compacted by satisfactory means in 12" loose lifts to 95% Standard Proctor (ASTM 0698). The final lift shall be tested at a minimum rate of one compaction test per 100 feet of trench and at every street crossing.

Laboratory services for backfill density tests shall be performed by a commercial laboratory approved by the Engineer, but paid for by the Contractor, unless otherwise noted. The cost for testing is to be included in the cost bid per foot of pipe.

b) State or Federal Road Right-of-Way: When the new pipe is installed by open cut method, within State or Federal road right-of-way or servitudes, the trench shall be backfilled according to Article 701.08, "Backfilling", of the LA. DOTO Standard Specifications for Roads and Bridges, latest revision.

Laboratory services for backfill density tests shall be performed by a commercial laboratory approved by the Engineer, but paid for by the Contractor, unless otherwise noted. The cost for testing is to be included in the cost bid per foot of pipe.

c) Open Ground: When the new pipe is installed by open cut method within easements or servitudes not directly influenced by vehicle movement or in open ground, the final backfill shall be with loose soil materials free from clods, clumps, sticks, stones and foreign matter. The final backfill shall be uniformly compacted by satisfactory means, to a density equal to that of the adjacent undisturbed soil. If settlement occurs, the trenches shall be refilled, compacted and made to conform to the original ground surface. The surface may be mounded over the top to provide for some after-settlement. About two months after completion, the Contractor shall go over the trench again with a roller, refill to the surface of the ground, and re-roll or tamp to a satisfactory condition. The final surface shall be left in a condition equal to that originally found at the start of the work.

F. CLEANUP As soon as the backfilling process is completed, the Contractor shall begin the removal of all surplus excavated material except that necessary for subsequent fill to address any settlement issues.

9. DISINFECTING WATER LINES:

SITE WATER UTILITY DISTRIBUTION PIPING 33 1116-10


After satisfactory pressure tests have been performed, all pipe and service lines shall be disinfected. The expense involved shall be borne by the Contractor except for the water required which shall be furnished by the Owner from the waterworks system without charge to the Contractor. The disinfection process will be performed at no direct pay and shall be included in the cost per linear foot of the pipe installed.

Disinfecting the water mains shall be done according to the provisions of AWWA C651. This work shall be performed in segments of the pipe line in accordance with a schedule to be submitted by the Contractor and approved by the Engineer before any work is commenced. Once properly disinfected and flushed, the Contractor shall contact a Louisiana Dept. of Health and Hospitals certified laboratory to sample the new water lines for microbiological testing to determine that such lines are free from contamination by coliform bacteria. The City of Lake Charles Water Division Laboratory is so certified and may be contacted at 491-1599 or 491-1554 to coordinate the sampling. There is not a fee from the City of Lake Charles for sampling and testing services.

Samples shall be taken from service connections or at locations as directed by the Engineer. Furnishing and installing connections for sampling purposes as needed shall be at no direct pay.

Once segments of a new water line are tested entirely free of bacterial contamination as per AWWA C 651 and put into service, periodic resampling and retesting shall be performed on the in service segments as an added safety precaution until completion of the entire project.

Water used to fill the new main during the application of chlorine shall be supplied through a temporary connection. This temporary connection shall be installed with an appropriate crossconnection control device, consistent with the degree of hazard for backflow protection of the active distribution system. Chlorine application shall not cease until the entire main is filled with heavily chlorinated water, 50 PPM minimum. This chlorinated water shall then be drawn off from each dead-end. As the water is drawn off and new water added, this new water shall be chlorinated. After all points show a strong indication of chlorine (confirmed by test kit or strong odor), the chlorinated water shall be retained in the main for at least twenty-four (24) hours, during which time valves and hydrants in the treated section shall be operated to ensure disinfection of the appurtenances. At the end of this 24-hr period, the treated water in all portions of the main shall have a residual of not less than 10 mg/L of free chlorine. After the 24 hr period, the main shall be flushed out with potable water. Should subsequent bacteriological tests show any pipe lines to be contaminated, the chlorination process shall be repeated in such pipe lines until satisfactory results of tests are obtained. No water from any pipe line shall be used for human consumption until bacteriological tests indicated that the water is entirely free of bacterial contamination. The forms of chlorine that may be used in the disinfection operations are liquid chlorine, sodium hypochlorite solution, and calcium hypochlorite granules or tablets. Prior to performing any disinfection work, the form of chlorine and the method of chlorination to be used shall be approved by the Engineer.

After final flushing and before the new water main is connected to the distribution system, two consecutive sets of acceptable samples, taken at least 24 hr apart shall be collected from the new main. At least one set of samples shall be collected from every 1,200 ft of the new water main, plus one set from the end of the line and at least one set from each branch. Samples shall be tested for bacteriological quality in accordance with Standard Method for the Examination of Water and Wastewater; and shall show the absence of coliform organisms.

3. JOINTING PROFILE GASKET CONCRETE PIPE:

Clean all dirt, dust, and foreign matter from the bell & spigot surfaces. Take extra care to clean the gasket seat.

Put the gasket on the spigot end making sure that the gasket is firmly against the shoulder of the offset.

Snap the gasket in several locations to insure that the designed stretch of the gasket has been equalized around the circumference of the pipe.

Lubricate the leading taper of the bell along with the entire bell surface with Lubricant. Apply a small amount of lubricant to the leading edge of the gasket. Align the spigot with the bell and push the pipe carefully until the spigot is all the way home.

All gaskets are to be identified with the cross section number, pipe manufacturers' name, specification and year and month.

Joints on smaller pipe up to 24" in diameter usually can be barred home. Place a block of wood across the invert of the pipe to protect the groove. When the subgrade is not firm enough to allow barring, use of a come along may be necessary to pull the joint home. This method should be used for larger pipe.

All RCP joints shall be wrapped with Mirafi 140-N drainage fabric, or approved equal, and secured in place with plastic strapping.

All drainage pipe initial backfill shall be with compacted sand up to the haunches of the pipe and the remainder of the pipe backfilled in 8" lifts to the top of the subgrade with the best of the excavated material. Compaction will be a minimum of 90% modified proctor under the hardsurfaced area and adjacent to the roadway.

4. EXCAVATION FOR DRAINAGE PIPE:

Before any excavation is started, adequate protection shall be provided for all lawns, trees, shrubs, landscape work, fences, hydrants and sidewalks that are to remain in place. Such protection shall be maintained as long as necessary to prevent damage from the Contractor's operations. Any damage that may occur shall be made good by the Contractor at no cost to the Owner.

No trench shall be opened more than two hundred feet (200') in advance of the completed sewer, without the written permission of the Engineer. In bad grounds, such as running sand, the work must be prosecuted vigorously night and day without interruption, when ordered by the Engineer.

Where the pipe sewers are built, the width of the trench at the top of pipes shall not exceed fourthirds (4/3rds) of the internal diameter of the sewer plus eight inches (8") provided that a greater width may be permitted by the Engineer when it is necessary to sheet the trench and there shall be at least four inches (4") clear space on each side of the pipe to permit tamping.

All excavation shall be open cuts with vertical sides except in special cases where the Engineer may permit sloping sides or tunnels. Trenches shall be excavated to the depths as shown on the drawings and where conditions make it necessary to such additional depths as may be directed by the Engineer.



The Engineer shall have the authority at any time to require the Contractor to discontinue the use of any excavating machine or other appliance, which, in his judgment, is not adapted to the purpose for which it is used.

Rough excavation shall not extend down to a point closer than four inches (4") from the finished subgrade. The last four inches (4") shall be removed just prior to laying so as not to disturb the subgrade.

Bell holes shall be dug of sufficient size to let the whole length of the pipe barrel to be bedded as required, and to allow the joints being properly made. The groove and bell holes shall be included in the unit price bid for sewer pipe.

Where the bottom of the excavation is not, in the opinion of the Engineer, a suitable foundation for the sewer pipe, the trench shall be deepened and a foundation as specified by the Engineer shall be placed under the pipe. This foundation is not included in the price bid for laying pipe and will be paid for as a separate item. Additional excavation necessary for pipe foundation shall be included in the price paid for foundations. Concrete for pipe foundation shall be proportioned to develop not less than 2,000 psi in 28 days.

The Contractor shall leave a berm of at least two feet (2') in width on one side of the trench, between the trench and the spoil bank, to allow free passage of the Engineer and to permit him to perform his work in an expeditious and satisfactory manner.

If the bottom of any excavation is taken out beyond the limits shown on the plans or prescribed by the Engineer, it shall be refilled at the Contractor's expense with concrete or other acceptable material in such a manner as the Engineer may direct.

The contract price per foot of pipe shall include all necessary shoring, sheeting, bracing, well pointing that may be required to complete the job in a workmanlike manner, unless otherwise provided for in the proposal.

The elevation of the bottom of the trenches are to be checked to the satisfaction of the Engineer before sewers are laid.

At all cross streets, the Contractor shall, when directed by the Engineer, make provisions for the passage of vehicles and foot passengers either by bridging or otherwise.

5. SHEETING AND BRACING: STRUCTURES AND CONDUIT

The Contractor is entirely responsible for the protection of his excavation against caving or settling of the banks and for all damage to pavement, buildings or other property caused by his excavation and he must protect the sides of the excavation by sheeting and bracing or shoring as may be necessary. If the Engineer disapproves of the precautions taken by the Contractor, he shall have the right to require that the excavation be braced and rendered secure to his satisfaction, even to the extent of requiring the use of close sheeting or sheet piling and suitable bracing (including all necessary nails, spikes or other fastenings) which may be of such form and dimensions and manner of application as will not be disapproved by the Engineer. The exercising of this right shall not be regarded as any assumption of responsibility by the Owner for the security of the trench or the surrounding area; full responsibility remains vested in the Contractor, the Engineer is merely expressing his distrust of the adequacy of the precautions proposed by the Contractor. The cost of all such shoring, whether placed on the Contractor's initiative, or by the order of the Engineer, shall be included in the prices bid for the structure being built; it will not be paid for as such.



When in the judgment of the Engineer, removal of sheeting or bracing is likely to cause damage to pavement or property, the Engineer may order such sheeting and bracing as he considers necessary left in place. Neither the giving of such orders by the Engineer nor his failure or refusal to issue such orders shall in any way relieve the Contractor of responsibility for damage to pavement or building.

Where pipe, conduit or other structures come within the limits of the trench, such pipe or structure shall be supported properly to the satisfaction of the Engineer.

The Contractor will be paid by separate pay item for all sheeting and bracing left in place at the written direction of the Engineer. The cost of all sheeting and bracing not required to be left in place shall be included in the price bid for sewers of each size and depth, and the Contractor will receive no additional compensation therefor.

Any upper sheeting left in place must be cut off at least two feet (2') below the ground surface after backfilling and tamping has reached this level and all rangers and braces about this level must be removed.

Where the sheeting for a pipe sewer is driven no lower than the top of the pipe, such sheeting may be withdrawn, provided that no sheeting is withdrawn until the trench has been refilled as hereinafter provided to a point not less than two feet (2') above the crown of the pipe.

Where it is necessary to drive sheeting below the top of the pipe, such sheeting shall be driven down to a point not less than two feet (2') below the bottom of the pipe and properly braced. Bracing above the pipe shall be placed as to allow at least one foot (1 ') clear space between the bottom of the bracing and the top of the pipe. The bracing next above the pipe and all sheeting and bracing below the top of said bracing may be removed after the trench has been backfilled at least two feet (2') above the top of the pipe.

The use of steel sheeting in trenches and its subsequent removal will not be permitted except with written approval of the Engineers in each case. Where steel sheeting is allowed and it is driven below the top of the pipe, the width of the trench must be great enough to allow a second set of wooden sheeting to be driven inside the steel sheeting. This wooden sheeting shall be driven before the excavation has been carried lower than the top of the sewer; it shall be driven, braced and left in place in accordance with the requirements of the preceding paragraph. The steel sheeting shall not be pulled until the trench has been backfilled at least two feet (2') above the top of the sewer.

Sheeting and bracing for manholes may be removed after the concrete has set up to the satisfaction of the Engineer.

An approved steel box may be used in lieu of sheeting.

6. PIPE LAYING:

All pipe shall be laid with the use of a laser.

All pipe shall be laid to a uniform line and grade, bell ends upgrade, with a firm and even bearing along the barrel of the pipe, close joints and smooth invert. The spigot end of the pipe is to be centered in and shoved tight and secured against the bell or socket of all previous laid pipe. The interior of each pipe shall be cleaned of all excess joint and foreign material before the next pipe is laid.

Pipe and fittings shall be so laid in the trench that after the sewer is completed, the interior surface of the bottom thereof shall conform accurately to the grades and alignments indicated on


SOWELA PHASE 1 Campus Revltallzatlon Program Ad: 391 Program LCTCS Projec:t #27064.11

the plans. At any state of construction of a straight stretch between any two consecutive manholes, the starting end of the pipe shall be clearly visible on looking through the pipe from the other end with full cross-section of the pipe in clear view.

All pipe shall be laid in conformity with the line and grades given by the Engineer and in the presence of the inspector. The pipe shall be laid with the use of a laser instrument.

No pipe shall be set in place while there is water in the bell hole; no joint shall be made with water standing in the trench or the bell hole.

Whenever pipe laying is stopped, either for the night or for any cause, the end of the pipe shall be securely enclosed to prevent the entrance of water, mud or other matter, and shall be secured in a such a manner as to prevent the end pipe from being dislodged by any sliding or other movement of the backfill.

Lift holes shall be grouted for the entire thickness of the pipe wall prior to backfilling and shall be braced from the inside of the pipe to prevent the grout from dropping through, or as an alternate lift holes may be plugged with the proper size concrete plug furnished by the manufacturer of the concrete pipe, and sealed with RAM-NEK.

7. BACKFILLING:

Backfilling of pipe trenches shall begin as soon as the Engineer or his representative is satisfied that the joints have been properly made and backfilling procedures have been approved. All drainage pipe shall be backfilled initially with compacted coarse sand up to the haunches of the pipe. Backfill above the haunches of the pipe shall be the best of the excavated material, free of roots and debris, or select material as provided in the Proposal. Backfill shall be carefully placed in the trench and compacted around the pipe. The utmost care shall be taken not to disturb the pipe by dumping fill material upon it from above, or shifting a pipe from its proper position by careless placement or unequal filling on the sides. The backfill material must not be placed faster than the workman can distribute and compact it. Similar care shall be exercised in backfilling up to one foot above the top of the pipe. The remainder of the trench shall then be backfilled and firmly compacted with approved power tampers, pneumatic, or other approved mechanical equipment.

Excavations crossing streets or locations under sidewalks, surfaced areas, or shoulders of improved streets, shall be backfilled in 8" lifts to a density of 95 percent Standard Proctor. Density tests shall be taken at every street crossing and at 100 foot intervals along the roadway. The density test specified herein shall be taken on the final 8" lift, or as directed by the Engineer. The cost for testing is to be included in the price bid per foot of pipe.

All voids or spaces caused by the removal of sheeting or bracing shall be carefully filled and compacted with properly shaped tools. Backfilling around manholes, structures, etc. shall be done when the Engineer considers the masonry or concrete to be sufficiently strong. The voids shall be thoroughly filled and well tamped. The Engineer shall have the right to forbid the use of any compacting tools or machines that he considers dangerous to the pipe or incapable of compacting the backfill properly.

The Engineer shall have the right to forbid the use of any compacting tools or machines that he considers dangerous to the pipe or incapable of compacting the backfill properly.

Topsoil shall not be hauled away, but shall be saved and used to cap the backfill, where applicable.


SOWELA PHASE 1 campus Revltallzatlon Program Act 391 Program u:rcs Project #27054.11

The Contractor shall notify the Engineer V'Aien he expects to start excavation. If the Owner desires the surplus excavated material not used in backfilling, the Contractor shall at his own expense, load the material into trucks provided by others or stockpile the material on abutting property or sites selected within a reasonable distance by the Engineer. It shall become the Owner's duty to provide reasonable hauling facilities so as not to hamper the Contractor in the normal progress of the work. Should the Owner have no need for the excavated material, it shall become the property of the Contractor and he shall load and dispose of it at sites selected by him.

8. JUNCTION BOXES, CATCH BASINS, INLETS:

This item shall consist of junction boxes, catch basins, and inlets constructed in accordance with these specifications at the locations and in conformity with the lines, grades and dimensions shown on the plans.

The Contractor shall do all excavation for structures and structure footings to the lines and grades or elevations shown on the plans or as staked by the Engineer. The excavation shall be of sufficient size to permit the placing of the full width and length of the structure shown. The elevation of the bottom of the structures, as shown on the plans, shall be considered as approximate only; and the Engineer may order, in writing, such changes in dimensions or elevations as may be deemed to secure a satisfactory job.

The Contractor shall do all bracing, sheeting or shoring necessary to perform and protect the excavation and the structure; also, as required for safety or to conform to governing laws. The cost of bracing, sheeting or shoring shall be included in the unit price bid for the structure.

The structures shall be constructed of Minor Structure Class "M" concrete, per Louisiana Standard Specifications for Roads and Bridges, 2000 Edition, conforming to the dimensions and form indicated on the plans. Any reinforcement required shall be of the kind, type and size, and shall be furnished, located, spaced, bent and fastened as indicated on the plans.

Inlet and outlet pipes shall extend through the walls of the structures for a sufficient distance beyond the outside surface to allow for connections, but shall be cut off flush with the wall on the inside surface unless otherwise directed. No rough edges will be permitted.

All structures are to be cast in place. If precast units are approved for this project, the tops will be left 18" below final grade. The tops will be cast in place.

The contractor shall be responsible for any field modifications necessary to accommodate the installation of the precast units.

If precast catch basins are approved on this project, a cast in place concrete collar, minimum of 6" thick, on the outside of the box shall be used to secure the inlet and outlet pipe connections. For 24" diameter pipe and smaller, the concrete collar shall be 6" wide. For larger pipe, the concrete collar shall be 12" wide. The same type concrete connection collars shall be used for connections to precast reinforced concrete box culverts.

The subgrade beneath the junction box shall be firm and dry. In the event that the subgrade is muddy, the mud shall be scraped off and approximately two inches (2") of bedding material be placed prior to placement of the concrete maintaining the minimum floor thickness of the box.

The cost of the bedding material is to be included in the unit price for the specific junction box.

When pouring the walls or tops of the junction box, an approved mechanical vibrator must be used. Keyways are required where one pour stops and another begins.


SOWELA PHASE 1 Campus Revltallzatlon Program Att 391 Program LCTCS Project #27064.11

Reinforcing steel shall be spliced a minimum distance of thirty (30) bar diameters. Minimum cover over the reinforcing steel shall be 1 W'.

All castings, frames and backfill shall be placed in the positions indicated on the plans or as directed by the Engineer, and shall be set true to lines and to correct elevation. All castings shall conform to the AASHTO M306 and to requirements of the Standard Specifications for Gray-Iron Castings, ASTM Designation A48, with subsequent amendments and additions thereto adopted by the ASTM and AASHTO. All frames and castings must be rated for HS-20-44 truck loading when located in the roadway regardless.

After the structure has been completed and has cured a minimum of 72 hours, all of the form work shall be completely removed in preparation for backfill. The area around the structure shall be backfilled with approved material, and shall contain no trash, rubble, lumber, broken concrete, etc. The material shall be placed in horizontal layers not to exceed eight inches (8") in loose depth, and compacted to the density, as required by the Engineer.

At the time of final acceptance, new structures shall be cleaned of silt, debris or other foreign matter, all voids and rough areas shall be grouted.

9. DUCTILE IRON SEWER PIPE FOR CONFLICT BOXES:

Ductile iron sewer pipe is required in the event that the drainage structures or drain pipe conflict with the existing sewer line. In the event the existing sewer line is deeper than the proposed drainage structure or pipe by more than 2.0 feet as measured from the bottom of the box or pipe to the top of the pipe, then the ductile iron sewer pipe will not be required unless otherwise directed by the Engineer.

A repair coupling shall be used to make the connections from the existing sewer line to the ductile iron pipe. The couplings shall be the proper size for the pipe involved and shall not be cut. The couplings and pipe shall be lubricated to insure ease of installation The clamps and shear ring shall be stainless steel. The gasket and the coupling shall conform to ASTM C 1173, and the gasket shall conform also to ASTM D 5926. The coupling shall be the Strong Back RC Series Coupling, as manufactured by Fernco or approved equal. All parts shall be installed in accordance with the manufacturer's recommendations. The price for these couplings shall be included in the bid unit price per foot for the pipe.

The ductile iron pipe shall be pressure Class 200 minimum and shall be internally lined with a 40 mil nominal dry film thickness of ceramic epoxy such as Protecto 401 Ceramic Epoxy by lnduron Corporation or approved equal. It shall be installed with a loose 8 mil thick polyethylene wrap. All coatings and wraps shall be installed in accordance with manufacturer's requirements.

The ductile iron pipe and sewer pipe shall be cut with an approved saw, acceptable to the Engineer. All cuts made to the pipe shall be smooth and even and normal to the pipe centerline. The pipe shall be measured and marked for its entire circumference to insure a normal plane to the pipe centerline when cut. The maximum allowable spacing between the ends of the joining pipe will not exceed 1/4". This will give approximately a total of 1/2 inch of play.

The Contractor shall exercise care in the removal of the conflicting sewer pipe, and salvage said pipe so that it may be reused as needed.

Where possible, the bedding of the existing sewer pipe should not be disturbed. If disturbed, maintenance limestone shall be compacted in its place to provide a solid base for the ductile iron pipe to rest on.



Prior to backfilling, the connection is to be inspected by the Engineer or his representative.

Sewer lines will only be allowed to be plugged by using an approved plug. The proper site plug shall be on the job and used to plug the closest upstream manhole to prevent the flow of sewerage into the construction trench. In the event the trench becomes muddy, a stone base shall be placed in the trench to help prevent the muddy subgrade from entering into the sewer line.

No debris or dirt will be allowed in the sewer line or manholes.

Any material which does enter the sewer line or manholes shall be immediately removed to the satisfaction of the Engineer.

10. TESTING:

Four (4) compressive test cylinders shall be made for every 24 cubic yards of concrete installed in drainage structures. There will be no direct payment for this work, but is to be included in the unit price bid for drainage structures, unless otherwise provided.
