Departmental Representative’s Authorized Personnel (DRAP): within the context of these Specifications, the term Departmental Representative’s Authorized Personnel refers to personnel appointed by Departmental Representative or authorized on-site by Departmental Representative. Departmental Representative’s Authorized Personnel provide recommendations/technical guidance to Departmental Representative’s, as required, for the enforcement of these specifications. Contractor: The contractor procured to undertake the site management, remediation and restoration is defined, within the context of these specifications, as the Contractor. Owner: within the context of these specifications, the term Owner refers to the airport authority that operates the Site. Site: Area of ground on which the location of the work will be undertaken. The FTA is located near the north-west end of the airport runway (See Figure 1 for locations). The project involves site preparation, construction of an HDPE lined LTU, and excavation and placement of hydrocarbon impacted soils into the LTU. The proposed LTU location is shown on provided drawings (Figure 1). The LTU will require construction to accommodate impacted soils from the FTA. Upon completion of tendering process and contract award, the final LTU location will be selected by the Departmental Representative during the on- site project kick off meeting. The LTU shall be constructed prior to the excavation and placement of hydrocarbon impacted soil from the FTA. The LTU will be required to be constructed to accommodate impacted soil from the FTA.

Phase II/III Environmental Site Investigation, Firefighter Training Area, Cambridge Bay Airport, Cambridge Bay, Nunavut dated March, 2011 by AECOM. Sample Plan of Construction and Operations Checklist (Appendix B) 1.3 DESCRIPTION OF WORK The required work to be undertaken by the Contractor for the project will include but not be limited to the following activities: Construction and completion of the LTU for the hydrocarbon impacted soils generated from the FTA. This would include, but not limited to, excavations of organics, scarify and compaction of native material, preparation and construction of HDPE lined (Owner and Contractor supplied) treatment area, supply and install granular cover material, placement of impacted soils within the LTU. Preparation of a site specific Health and Safety Plan. During the completion of the site work the Contractor is responsible for site health and safety and shall designate an on-site safety coordinator. Preparation of a Plan of Construction Operations. The Contractor is responsible to work or collaborate with the airport to develop this document together for airport specific requirements. o A sample of a Plan of Construction Operations along with a checklist, can be found in Appendix B. Mobilization of equipment and materials, installation of hoarding and project kick-off meeting. Public Works and Government Service of Canada (PWGSC) has supplied (supply only) 16 rolls (18,572 m2) of HDPE Geomembrane liner for Contractor use. Location of rolls to be provided to Contractor on site by Departmental Representative at time of site meeting. Obtaining all necessary permits to undertake the project. These may include, but not be limited to, permit to excavate and to construct the LTU.

READY FOR TENDER CAMBRIDGE BAY AIRPORT Section 00 11 21 FIRE TRAINING AREA REMEDIATION SUMMARY OF WORK SECTION CAMBRIDGE BAY AIRPORT, NUNAVUT Page 3 of 6 Relocation, protection and support for all on-site utility services which would potentially be impacted by excavations at the FTA and LTU area. Excavating, loading, hauling and placement of hydrocarbon impacted soils from the FTA into the LTU. Dewatering of excavations shall be necessary where groundwater is encountered, prior to the excavation of impacted soils at the FTA. Excavated areas at the FTA shall be backfilled and the site surfaces within the excavated areas should be restored to pre-project conditions and graded in way to allow drainage. Supply and Install groundwater monitoring wells as follows: o Installation of three (3) groundwater monitoring wells (to a maximum depth of either the bedrock or permafrost interface, which has been determined to be approximately 2.0 meter below grade at the proposed LTU area) outside of the LTU berm boundaries (See Figure 2 for proposed groundwater monitoring well locations). o Eight (8) groundwater monitoring wells located outside of the impacted soil excavation boundaries at the FTA (to a maximum depth of either the bedrock or permafrost interface, which has been determined to be approximately 2.0 meters below grade at this area). Exact locations of the groundwater monitoring wells at the FTA will be determined during the remedial excavation process by the Departmental Representative, so as to not interfere with the remedial excavation works. Demobilization of equipment, materials and hoarding including disposal of all waste materials generated during the site remediation. Operation and maintenance of the LTU is to be done by others and is not included in this contract The above list must be completed in accordance with these Tender Documents. 1.4 WORK SEQUENCE .1 Co-ordinate Progress
