SPECIAL PROVISIONS

SP-07 WATER FOR CONSTRUCTION

Water for construction is the Contractor’s responsibility. The Contractor shall make all necessary arrangements as such. The Contractor is responsible for providing all required fittings, meters, hoses, backflow assemblies, valves and other appurtenances required for obtaining water for construction.

If water is acquired from metered fire hydrants, Contractor needs to know and understand proper hydrant operation procedures as they are the party ultimately responsible for improper hydrant connections or any other improper operation of a hydrant. The contractor is responsible to teach proper operation procedures to all employees using hydrants. This includes water truck drivers or any other employees of the company that operate hydrants for any reason.

Meter Hydrant Connection Procedures

1. Perform a safety check of the hydrant. Check the hydrant visually, and shake the hydrant with your hands to make sure it is rigid (do not use a movable hydrant – they are dangerous and serious injury to the operator may result). Check the hydrant to ensure the caps are tight.

2. Remove hydrant nozzle cap.

3. Attach metering device and hose and install brace support. All hydrant connections must include a RPZ backflow assembly or device acceptable to the CO at all times.

4. Open hydrant slowly. It should take more than 60 seconds to fully open to prevent surging on the water system. Open completely to shut off drip drain while hydrant is in use. Valves downstream of the hydrant shall not be used to control flow.

5. They discharge end of the hose should not be inserted under any circumstances, into a tank or container underwater or laid on the ground to make and lay in its own pool of water. There must be at all time an air gap between the end of the water hose and the container.

6. Upon filling the tank or upon completion of the permitted use, slowly close hydrant valve.

7. Remove hose

8. Replace nozzle cap and tighten securely.

9. No hydrant shall ever be left without the cap replaced and securely tightened.

The Contractor is required to obtain written permission for obtaining water from any public or private water system and provide documentation to the Government.

SP-08 SITE RESTORATION

Site Restoration is an important part of this project. Site Restoration is replacement or reconstruction of site improvements to rights-of-way, easements, public property, and private property that are affected or altered by construction operations, with improvements restored to a condition which is equal to, or better than, that which existed prior to construction operations. These Site Restoration items include but are not limited to; concrete curb and gutter replacement, sidewalk replacement, concrete surfaces, asphalt replacement, gravel restoration, seeding, sod, and irrigation system repair.

Initial restoration (rough grading, temporary aggregate if necessary, removal of excess excavated material and debris) shall be done each day to the extent necessary to allow the movement of local traffic and permit access to all areas for emergency vehicles. Maintenance of streets, drives, sidewalks, etc. shall be the responsibility of the Contractor (including dust control, grading, stabilization, etc.) until the

DustinFarren restoration is complete and has been accepted by the Government and CO. Restoration of each street or section of utility line shall follow the construction in a timely fashion so as to minimize inconvenience to the Government and the general public. The manner in which this restoration is done by the Contractor will be a determining factor in the approval of partial payment requests.

After utility work is completed on underground utilities and submitted on monthly estimate for payment, complete site restoration for those utility segments before next monthly estimate for payment is submitted, unless extended in writing by Government and CO. If site restoration is not completed, the Contractor’s partial payment request may be denied or additional retainage may be withheld.

SP-09 PRIVATE ACCESS

At all times during construction, afford government access to their property to the highest degree possible. Ensure that businesses will have at least one approach open at all times, if possible, and open closed-off approaches as quickly as possible.

The Contractor shall provide a minimum of 48 hour notice to residents of construction in front of their private residents and that access will be impacted.

The maximum un-backfilled open trench within the street sections during each day of construction shall not exceed 50 lineal feet.

SP-10 LANDSCAPED AREAS

Repair any landscaped or vegetated areas on private or public land that are scarred or destroyed during construction to an equal or better condition than that prior to the start of construction. This will include removing, replacing and grading topsoil. Replace all landscaped and/or grass areas disturbed during the construction process with a minimum of 6-inches of topsoil. Furnish and install sod as necessary to replace grass in areas as needed to restore to original condition.

Work to paid for under bid item “Type C Surface Restoration (Lawn)”. See Section 01275: Measurement and Payment for more information.

SP-11 REMOVAL AND REPLACEMENT OF FENCES, SIGNS, SIDEWALKS, CURBS,

GUTTERS, POSTS, BARRICADES, ETC.

Culverts, fences, signs, decorative rocks, newspaper boxes, posts, sidewalks, curbs, gutters, propane tanks, satellite dishes, barricades, etc. may be encountered during construction that may hinder construction operations. Whether on private or public property, remove and replace these objects as necessary to conduct construction operations. Replace objects removed in as good a condition as previously existed and to the satisfaction of the CO.

SP-12 REMOVAL AND REPLACEMENT OF EXISTING FENCES

It is the responsibility of the Contractor to coordinate with Government, prior to removing existing fences, to determine procedures, length of time fence may be removed, and requirements for temporary fencing until permanent fencing is complete.

DustinFarren

All fence removed must be reassembled prior to the end of the workday. A secure fence will be required at the end of each workday. The trench under the fencing section must be backfilled at least 20’ either side of the fence at the end of each workday. Removal and replacement of fences and/or gates is considered incidental to the portion of contract work being completed for which the fence or gate removal is required and the cost is included in the bid price for the related item. No additional payment for fence and/or gate removal and replacement will be provided.

SP-13 STAGING AREA

The Contractor is required to make all arrangements for a construction staging area for material, equipment, office and related items as necessary. The Government owns areas that may be used as a location for the construction office and/or as a staging area for materials and equipment storage to the extent area is available.
