1.1 CONSTRUCTION SITE PLAN

Prior to the start of work, submit a site plan showing the locations and dimensions of temporary facilities including layouts and details, equipment, and material storage areas both onsite and offsite, access and haul routes, avenues of ingress/egress to fenced areas (e.g., the assigned storage area), details of the fence installation (if used), and the number of trailers to be used. Identify any areas which may have to be graveled to prevent the tracking of mud. Indicate if the use of a supplemental or other staging area is desired. Show locations of safety and construction fences, site trailers, construction entrances, trash dumpsters, temporary sanitary facilities, and worker parking areas. The plan shall also show where temporary utility hook-ups are to be located, if required, and how grounding of equipment and trailers will be achieved.

2.1 TEMPORARY SIGNAGE

Project identification and safety signs are not required for this project.

2.2 TEMPORARY CONCRETE BARRICADES, SAFETY FENCE, AND CHAIN-LINK FENCE

The Contractor shall erect and maintain temporary concrete barricades and/or temporary safety fencing to limit public access to hazardous areas. The Contractor may also erect a temporary six-foot-high chain-link fence around storage areas and trailers, if desired. Temporary barricades, safety fencing, and chain-link fencing need not be new, but shall be in overall good condition.

2.2.1 Temporary Concrete Barricades

Concrete barricades shall be required whenever safe public access to paved areas such as roads, parking areas or sidewalks is prevented by construction activities or as otherwise necessary to ensure the safety of both pedestrian and vehicular traffic. Concrete barricades shall be securely placed and clearly visible. All barricades shall be provided with a flashing light (amber yellow, 5 candelas effective intensity, 55-75 flashes per minute). All barricades must be anchored or of sufficient mass to retain an established position where they are placed. Continuous burning lights shall have an effective intensity of 10 candelas. Place barricades at 10-foot maximum intervals and use dual markers and lights at corners and ends. Flashing lights shall be maintained to operate nightly during construction with adequate illumination to provide sufficient visual warning of the hazard during both day and night. The Contractor shall check each flashing light for operation every night before leaving the project area.

2.2.2 Temporary Safety Fencing

Temporary safety fencing shall be used to limit access to active construction areas. The safety fencing shall be a high visibility orange colored, high density polyethylene grid or approved equal, a minimum of 42 inches high, supported and tightly secured to steel posts located on maximum 10-foot centers.

3.8.3 Storage Area and Temporary Chain Link Fencing

The Storage Areas for use by the Contractor, for work and storage of equipment, materials, and trailers during the life of this contract shall be located on the Natick SSC facility. A specific location will be determined at the Preconstruction Conference. The Contractor shall confine its storage areas to the limits as designated or approved by the Contracting Officer and shall be responsible for the security of the areas. Upon completion of the contract, and at no additional cost to the Government, remove all equipment and materials, except as otherwise specified, and restore the sites to their original condition as approved by the Contracting Officer.

Trailers, equipment, or materials must not be open to public view with the exception of those items which are in support of ongoing work on any given day. Do not stockpile materials outside the storage area in preparation for the next day's work. Park mobile equipment, such as tractors, wheeled lifting equipment, cranes, trucks, and like equipment within the storage area at the end of each workday.

At the designated storage areas, the Contractor may erect temporary chain-link fencing if desired. Except for equipment and materials which are in support of ongoing work on any given day or unless such equipment or materials are assigned a separate and distinct storage area by the Contracting Officer away from the vicinity of the construction site but within the project site boundaries, equipment and materials shall be stored and placed inside the temporary chain-link fencing.

3.8.4 Maintenance of Storage Area

Temporary chain-link fence, if used, shall be kept in a state of good repair and proper alignment. Should the Contractor elect to traverse, with construction equipment or other vehicles, grassed or unpaved areas which are not established roadways, such areas shall be covered with a layer of gravel as necessary to prevent rutting and the tracking of mud onto paved or established roadways; gravel gradation shall be at the Contractor's discretion. Grass located within the boundaries of the construction site shall be mowed for the duration of the project. Grass and vegetation along fences, buildings, under trailers, and in areas not accessible to mowers shall be edged or trimmed neatly.

3.8.5 Security Provisions

Adequate outside security lighting shall be provided by the Contractor at the Contractor's temporary facilities. The Contractor shall be responsible for the security of its own equipment.

3.8.9.2 Construction Equipment

In addition to the requirements of EM 385-1-1, all temporary wiring conductors installed for operation of construction tools and equipment shall be either Type TW or THW contained in metal raceways or may be multiconductor cord. Temporary wiring shall be secured above the ground or floor in a workmanlike manner and shall not present an obstacle to persons or equipment. Open wiring may only be used outside of buildings, and then only in strict accordance with the provisions of the National Electrical Code.

3.8.9.3 Circuit Protection

In addition to the requirements in EM 385-1-1 and NFPA 70, all 15 and 20-ampere receptacle outlets used for obtaining power during construction shall have ground fault circuit interrupters (GFCI) for personnel protection. All generator-powered 15- and 20-ampere, 60 Hertz receptacle outlets shall have GFCI'S, and shall be properly grounded. A testing means shall be provided which will impose a measured fault of 5 milliamperes, plus or minus 1 milliamperes, and result in tripping the GFCI unit.

3.8.10 Weather Protection of Stored Equipment and Materials

Take necessary precautions to ensure that stored equipment and materials, and openings and other critical openings in the temporary storage area are monitored carefully. Take immediate actions required to seal off such openings when rain or other detrimental weather is imminent, and at the end of each workday. Ensure that the openings are completely sealed off to protect materials and equipment in the temporary facilities from damage.

3.8.10.1 Building and Site Storm Protection

When a warning of gale force winds is issued, take precautions to minimize danger to persons, and protect the work and nearby Government property.

Precautions must include, but are not limited to, closing openings; removing loose materials, tools, and equipment from exposed locations; and removing or securing scaffolding and other temporary work. Close openings in the work when storms of lesser intensity pose a threat to the work or any nearby Government property.

3.8.11 Stormwater Pollution Prevention

To prevent sediment laden runoff from entering any resource areas such as lakes, ponds, rivers, or wetlands, provide erosion prevention and sediment controls (such as entrenched staked straw bales and sediment (silt) fence) in areas where land disturbance has resulted from the installation temporary facilities and use of storage areas. See Temporary Environmental Controls.

Materials resulting from demolition activities which are salvageable shall be stored within the storage area. Stored material not in trailers, whether new or salvaged, shall be neatly stacked when stored.

3.10.1 Dumpster

Provide dumpsters for the collection of trash and debris. Equip dumpsters with a secure cover. Keep cover closed at all times, except when being loaded with trash and debris. Locate dumpsters behind the construction fence or out of the public view. Empty site dumpsters at least once a week or as needed to keep the site free of trash and debris. For large demolitions, large dumpsters without lids are acceptable but should not have trash and debris higher than the sides before emptying.

3.10.2 Burning

Burning of brush, trash, or debris will not be permitted on the project site nor Government property.
