SECTION 202 - EXCAVATION

202.01 DESCRIPTION

The following is added to this Article of the Standard Specifications:

The excavations shall be made to conform with the lines of the finished grades and structures wherever practical.

The excavations shall not be carried below the required grades by machine and back-filled to the grade of foundations, bottom slabs, footings, or pipelines. The trench in which pipe, manholes, or inlets are to be constructed shall be excavated from the surface and to such depths and widths (not less than 12 inches greater than the maximum external dimension of the structure) as will give suitable room for bracing and supporting, pumping and draining, and for removing from the excavation any material which the Engineer may deem inadequate for foundation. All excavations shall be of sufficient width to permit work to be done completely, in the manner intended and of the size specified and/or shown on the plans.

The length of the trench to be opened or the area of the surface to be disturbed and restored at any time will be limited by the Engineer with regard both to expeditious construction, and convenience to the Owner. New trenches will not be excavated if previous trenches are in need of back-filling or labor is needed to restore the surface of the ground to a safe and proper condition.

Trenches for pipes shall be a minimum of 2' wider at the bottom than the outside diameter of the pipe and shall not remain open in excess of 50' in length nor remain open overnight.

Excavation for subsurface structure shall also include the excavation required to provide compacted granular bedding as shown in the Construction Details. Whenever the material at the bottom of a bedding or other subsurface structure excavation is soft or otherwise unsuitable, it shall be removed to such depth as the Engineer may require and the space back-filled with Coarse Aggregate Type 57.

All excavations for pipelines shall be clear of boulders, rock, masonry, or other similar material which shall be excavated to a level at least six inches below the bottom of the pipe, and carefully refilled with approved material mechanically compacted to provide a stable subbase. Rock or boulders shall be removed from sides of trenches to 12 inches outside the wall of the pipe, unless permission to do otherwise is expressly given. Gravel or stone bedding shall be provided, placed and compacted to the minimum depths when indicated on the plans. The bottom of the trench shall be excavated where the earth is suitable for good foundation to the form and size of the lower portion of the pipe or other structure, so that there shall be full and adequate support for the structure which is to be built on it. Ample excavation shall be made under and around the pipe joints for jointing and to relieve the bell of shearing forces.

Excavation, unclassified, shall also include removal of hot mix asphalt pavement overlay, hot mix asphalt pavement, and reinforced and non-reinforced concrete pavement.

In addition, excavation, unclassified, shall include the sawcutting of the existing pavement. This shall be at a distance of one foot from the edge of the existing pavement that is to remain in place to form a proper bond between the new pavement and the existing pavement, or as directed by the Engineer.

Excavation, unclassified, shall also include, as required, the separation and temporary stockpiling of suitable earth materials from excavation and the rehandling of the stockpiled materials for the construction of the roadway embankments, subbase, base courses and backfill if and where directed by the Engineer.

Excavation, unclassified, shall also include removal of unsuitable material in cut sections disclosed by proof rolling.

Where rock is encountered at the locations of the proposed inlets, manholes, and headwalls, the rock shall be dressed to level beds as directed by the Engineer.

Unauthorized Excavation

Special care will be taken with the final six inches of all excavations. In no case shall the excavation be carried below grade by machine and backfill used to establish the required grade. Where the excavation has been carried below grade through error or because of slides or cave-ins, the contractor shall at his own expense restore such areas with 3/4 inch graded gravel or crushed stone or as directed by the Engineer. If the Contractor excavates

2-14

H:\Legacy\Howell-FS1\SEC\Pennsauken Township\Project Files\PK00501.C01 - Municipal Pool Improvements\Specifications\13 - Div 2.doc below the required grade for structures, the overexcavation shall be filled with material subject to the requirements of the Engineer. The material may include 2000 psi concrete if so ordered by the Engineer.

Sheeting and Bracing

Where necessary for safety or to prevent disturbance, damage, or settlement of adjacent structures, pipelines, utilities, improvements, or paving, excavations shall be sheeted and braced. Any damage to new or existing structures occurring through settlement, water or earth pressure, or other causes due to inadequate construction procedures of the Contractor in any other manner, shall be repaired by the Contractor at his own expense.

Dewatering and Protection from Flooding

The Contractor shall dewater the excavations promptly and continuously throughout the progress of the work and shall keep the excavations dry at all times until the structures to be built therein, are completed. Where work is to be performed below groundwater level, the Contractor shall provide, operate and maintain dewatering facilities sufficient to maintain the excavation free from groundwater for the time required to complete the work in the proper workmanlike manner.

The Contractor shall protect uncompleted work from flooding during storms or from other causes. All pipelines or structures not stable against uplift during construction or prior to completion shall be thoroughly braced or otherwise protected.

All necessary precautions shall be taken to prevent disturbance of, and to properly drain, the areas upon which concrete is poured, and upon which pipe is to be laid. All concrete shall be kept dry for one month after pouring except curing.

All water pumped and bailed from the trench or other excavation shall be conveyed in a proper manner through an approved settling basin and to a suitable point of discharge by the Contractor at his own expense.

Construction Safety

The Contractor shall follow the various requirements contained in the Construction Safety Code, latest edition, as prepared by the State of New Jersey, Department of Labor and Industry, Bureau of Engineering and Safety. In addition, the Contractor shall comply with the "Construction Safety and Health Regulations" of the Occupational Safety and Health Administration, Title 29, Chapter XVII, Part 1926 or latest revision.

Protection of Existing Pipelines and Structures

Care shall be taken not to relocate without the consent of the Engineer any sewers, drains, culverts, water or gas pipes or structures near them that could affect their stability. All utilities shall be securely hung, braced, or supported in place until the work is completed. Whenever it is necessary to interfere with said structures or pipelines, the Contractor shall maintain their services at his own expense and repair all damages caused by his act or neglect of work. The integrity of all pipelines and structures shall be maintained throughout the construction and same shall be left in an equivalent condition or improved condition after completion of construction.

Adequate precautions shall be taken to prevent settlement of existing improvements.

In case water pipes, gas pipes, conduits, or other utilities become damaged or broken in the prosecution of the work, the Contractor shall give immediate notice to the proper authorities and shall be responsible for any damage to persons or property caused by such breaks. Failure to give prompt notice to the authorities shall make the Contractor responsible for any needless loss of water or gas, or for interruption of services.

When house connections or service pipes supplying water or gas as well as underground sprinkler systems are broken during construction, the Contractor shall repair them at his own expense. Delays, such as would result in adjoining buildings having to do without water or gas for a needlessly long period, will not be tolerated. The Municipality reserves the right to remedy such delays by ordering outside parties to make such repairs at the expense of the Contractor.

If so directed in writing, the Contractor shall make permanent changes in the location of water mains if they are obstructing the new structures to be built.

202.04 MEASUREMENT AND PAYMENT

This article of the standard specifications is amended as follows:

Excavation shall not be measured for payment and shall be included in the various bid items in the proposal.

If the plans have been altered or when disagreement exists between the Contractor and the Engineer as to the accuracy of the plan quantities in any balance, or the entire project, either party shall have the right to request and cause the quantities involved to be measured as specified hereinafter.

The average end areas method will be used for computing the volume of earthwork except where it is impractical to measure material by the cross sectional method due to the erratic type or location of the work. In the event of such situation, the excavation may be measured by acceptable method involving three-dimensional measurements.

Computations for excavation in intersection areas and abandoned drainage systems will not be done by the average end areas method, but rather by a suitable method selected by the Engineer to provide an accurate quantity.

Separate measurement and payment will not be made for sawcutting of any kind. The cost for this work shall be included in the unit price bid for each item requiring same.

Unstable material disclosed in an embankment which was not constructed properly, in the Engineer's opinion, shall be removed and replaced at no additional cost to the owner.

No separate payment will be made for the following but cost thereof shall be included in the respective unit prices submitted for the various items listed in the Proposal:

1. All excess and unsuitable excavation for which no use is shown on the plans or prescribed in the specifications shall be disposed of by the Contractor at sites to be provided by the Contractor outside the contract limits of the project.

2. Providing sheeting, shoring, bracing which would be pulled away or left in place as per direction of the Engineer.

3. Dewatering, if necessary, of whatever means.

No separate payment will be made for excavation required to provide bedding for all subsurface structures but the cost thereof shall be included in the respective unit prices submitted for the various items of subsurface structures listed in the Proposal.

No separate payment will be made for Pipe Bedding; rather the cost thereof shall be included in the unit prices of the various pipes in the proposal.

301.02 MATERIALS

The following is added:

Subbase shall be constructed using existing insitu granular soils or furnished and installed 2" to 2-1/2" clean stone, or aggregate, NJDOT type 57 if and where directed by the engineer.

Soil support fabric, or geotextile, if and where ordered, shall conform to Subsection 919.01.

301.03 CONSTRUCTION

301.03.01 SUBBASE

A. Preparing Subgrade

Where directed by the Engineer, the contractor shall install a geotextile soil support fabric prior to the placing of the proposed dense graded aggregate base course and/or clean stone subbase. The subgrade shall be cleared of all large stones and sharp objects that could puncture the fabric prior to placement. The fabric should then be rolled out into the sub-grade by at least two men, beginning on the firmest soil of the site perimeter to establish an anchor point. Lateral and longitudinal seams should be overlapped 3' or more or sewn. Aggregate may be used to hold down the fabric until the sub-base can be placed. Ground securing pins may also be used on the overlap sections.

Once the fabric is in place, the aggregate subbase can be backdumped onto the fabric beginning on firm soil at a point just in front of the fabric. The aggregate should be spread in lifts to allow proper compaction while not overstressing the fabric. Where extremely soft subgrades exist, care should be taken during aggregate placement to insure that the fabric is not moved out of position. Deformations or ruts that appear in the subbase shall be filled with additional aggregate until stabile. Areas of the fabric which are damaged or moved out of position during aggregate placement shall be exposed and covered with a fabric "patch" overlapping 3 to 4 feet onto unaffected areas.

B. Spreading and Grading

C. Compacting
