X. BARRIERS & RESOURCE PROTECTION MEASURES

· Site Cleanup:

Although the government understands that a construction site is by nature not clean, the NPS desires to have work sites that are as clean, free of construction debris, and uncluttered as possible. For this reason, the Contractor shall clean work sites continuously to adhere to basic cleanliness and safety standards, and all FAR clauses for site cleanup. This shall include but is not limited to cleaning all haul routes and using covers for trucks hauling fill material. The Contractor shall respond to all government requests to clean the site within 1 hour. Ultimately it will be the contracting officer representative, and not the Contractor, who will determine what, constitutes a clean work site. The Contractor shall provide animal proof trash containers as directed by the COR.

· Construction Barriers & Fencing:

Construction fencing shall be included in the Contractor’s coefficient and shall be provided on all construction projects, unless specifically told otherwise. The fencing is intended not only for site safety and cleanliness, but also for aesthetic purposes. Dependent on specific requirements, worksite fencing may include government-approved screen material to hide the work site from visitors and Park Unit personnel. The Contractor shall determine the fencing requirement and area to be screened for the government’s review and approval. The Contractor shall respond to government requests to clean up or fix a downed fence at a job site within 1 hour. For the purposes of this contract, the definition of “construction fencing” shall be any barrier that the Contractor has to erect for site safety, cleanliness, screening, and/or protection of government- or Contractor-owned material inside or outside of any facility.

· Utility Shutdowns, Work Interruptions, and Street Closures:

The Contractor shall provide a minimum notice of 7 calendar days’ notice prior to any utility shutdowns and 10 calendar days for any road closures if it becomes necessary to interrupt the work activities of personnel at the project site, for construction purposes. The Contractor shall immediately notify the COR and/or contracting officer if underground utility lines are severed or damaged in anyway. Any utilities that are cut, damaged, or disrupted by the Contractor within three feet on either side of a staked or otherwise marked location, will be repaired at no cost to the government.

· Authorizations to Dig:

The Contractor shall be responsible for processing and obtaining all required authorizations and clearances to dig (digging permits) and obtaining blue stake location services. Once a construction site has been marked, it is the Contractor’s responsibility to maintain the markings. If work does not commence on-site within 30 calendar days of the blue stake approval and the Contractor has not maintained the blue stake markings, the Contractor shall request a re-stake prior to commencing actual site work. No extension of the task order performance period shall be approved due to a Contractor’s decision to not start contract work within 30 days of the blue stake approval. All costs of construction blue staking and potholing to verify utility locations shall be calculated as a part of the Contractor’s coefficient.

· Communication Systems:

The Contractor shall have a communications system (i.e., Cell Phones, Radios) that will allow the government to relay messages to or obtain answers/responses from Contractor personnel in the field. If cell phones are used for on-site communications, the Contractor shall provide the appropriate numbers to the contracting officer’s representative (COR). If radios are used for on-site communications, the Contractor shall provide use of a compatible radio unit to the COR. The Contractor shall also provide e- mail addresses for all key employees, which will allow electronic communications between the government and Contractor key personnel.

· Points of Contact:

The Contractor shall provide a primary and alternate point of contact (POC) that can be reached 24 hours a day, 7 days a week for emergencies. The individuals must have the authority to make binding decisions and commitments on behalf of the Contractor, in response to emergency / exigent situations and conditions.
