Mr. Himanshu Mehta, P . E . 19 Apri1201 l Page 6 Phase 3 — Contractor Procurement Services Under this phase, Geosyntec will prepare construction documents for procuring a construction contractor for Phase 2 construction . This will include preparation of the request for bid (RFB ) documents ; attending the pre -bid meeting ; responding to bidders ' questions and preparing required updates to the bidding document throughout the bids preparation process ; evaluating bids ; and preparing a recommendation to SWDD of the prefer bid for Phase 2 construction . Our budget is based on the assumption that the entire RFB package including the construction drawings, specifications document, responses to questions and project update will be uploaded by the County ' s Purchasing Division onto Demandstar website where it will be available for downloading by candidate contractors wishing to respond to the RFB . For budgeting purposes , this phase has been broken down into three tasks, as described below . Task 3. 1 : Preparation of Construction Documents Geosyntec will prepare the construction documents (drawings , technical specifications, material quantities, and CQA Plan) required to procure a contractor for Phase 2 construction of Cell 1 of Segment 3 Expansion . Note that this phase of construction includes : ( i ) demolition of the four manholes east of Segment 2 ; ( ii) construction of a new leachate conveyance system to convey leachate from Segment 2 to a manhole north of the existing Class I landfill ; ( iii ) demolition of the stormwater conveyance structures north and south of Segment 2 ; ( iv) re -routing of the stormwater conveyance to the sedimentation pond ; (v) tie- in of the new liner system to existing Segment 2 liner system ; and (vi) design of the foundation and pad system for the flare system relocation . Details of the demolition of the manholes and stormwater structures , construction of the new leachate and stormwater conveyance systems as well as tie - in of the Cell 1 liner system to Segment 2 liner system will require additional analyses and close coordination with SWDD and its new landfill operator (Republic Services) . These components of the construction project all occur on the northern and eastern slopes of Segment 2 (next to the access road to the existing Class I Landfill ) and , therefore , will require close coordination between the construction contractor and the landfill operator to avoid interruptions to construction activities and/or normal landfill operations . In addition, all these activities generate waste materials that will have to be removed from the construction area and properly disposed of with cooperation of the landfill operator. SWDD may also be involved in the event of having to re-route the landfill traffic to avoid interference with the construction work . Another critical component of this project is the relocation of the existing gas flare to an area north of Segment 3 Expansion footprint, near the yard waste processing area .
