6.10.11 Contractor shall account for and replenish the Site’s chemical treatment supply that will be depleted by the act of draining and refilling directly tied to the activities of this project’s scope.

6.10.12 Hazardous Condition (HAZCON) Notification: The contractor shall provide notification of all potential

HAZCONs to describe when the facility is operating in a decreased state of reliability or operational ability.

It is permissible for the contractor to intentionally place the site in a HAZCON to support work outlined under this contract. This is with the understanding that the contractor shall first fully coordinate and seek approval through DISA before proceeding with any work that puts the site in a HAZCON.

6.10.12.1 HAZCON is defined as a condition in which the normal, alternate, backup, or redundant power source or mechanical equipment is not available, but power and cooling is not interrupted to the load. It is therefore not a true outage at the load, although it may be a partial outage of one bus, circuit, mechanical system, etc.

6.10.12.2 Contractor shall provide a request and receive approval for the HAZCON at least 28 calendar days prior to the HAZCON event.

6.10.12.3 Contractor shall ensure that all HAZCONs are clearly noted in the equipment installations’ sequence of events, i.e., Method of Procedure (MOP), hot taps to reduce installation time, etc.

6.11. Installation Surge Requirements:

-An "Installation Surge" is defined as an installation/site condition or issue that cannot reasonably be expected to be accounted for during preparation of the Government's requirement nor the contractor's preparation of their proposal. The nature of completing projects to provide new condenser water filtration and condenser water piping system upgrades within existing facilities infrastructure contains a certain degree of risk/unknowns in encountering unforeseen site conditions. As a result, it is not feasible for the

Government, nor the contractor, to anticipate all the conditions and/or issues that may arise during installation. Some of these conditions include, but are not limited to:

-Substandard and non-code compliant electrical and mechanical equipment installations found during new or replacement equipment installation. In such cases, these items must be brought into compliance with applicable Life Safety and Federal Government guidelines.

-Existing equipment infrastructure that must be modified in order to accommodate the installation of the new or replacement equipment under contract. This example includes existing conduit, conductors, waterlines, communication or controls cabling that must be relocated or re-routed to allow equipment under contract to be installed in the specified location.

-Installation contingencies are anticipated throughout the life of this contract; therefore, the Government intends to issue a CLIN that will support resolution of the issues in real time. If at any time during the project installation the contractor identifies any work/requirement that falls within the scope of the

Installation Surge CLIN, the COR and Contracting Officer should be notified immediately and prior to work commencing; the contractor shall include a rough estimate of costs to correct the issue within their notification to the COR and Contracting Officer. Once an installation Surge requirement is identified by the contractor to the appropriate Government POC (identified in paragraph 1), the Contracting Officer will contact the Contractor's Program Manager in writing to authorize performance start immediately under the

Installation Surge Cost CLIN. The installation Surge CLIN shall only be authorized for mission-critical repairs/ support as identified by the Contracting Officer.

-Surge requirements will be documented and reported. Equipment/Parts under this CLIN shall be reimbursed at unit cost. Performance on this effort will occur to the extent that Government funding is provided. All proposed labor rates under this CLIN shall be in line with current contract rates.
