Y1DA--Surgical HVAC Systems Replacement 556-23-127

the surgical area located in Rm 3C-100 of Bldg. 133. These air handlers supply the surgical suites 1-4 and all administrative areas except OR-5 and Cystoscopy. The renovation will remove and replace all AHU components as described in the project drawings and specifications. Part 2: Period of Performance: The following model presents the summary logic of the milestone sequence working backward from the delivery date of the longest lead time in the critical path to determine a mobilization date, and then forward from the delivery date of the longest lead time to completion of all work. Listed milestones and phases (calendar days): Notice To Proceed Day 0 Division 01 Submissions Completed Day 21 Division 01 VA Reviews Day 42 Division 02+ Submissions Day 84 Division 02+ VA Reviews Day 98 Mobilize and Demo Day 98 (If all pre-construction submittals were approved) Construction Complete Day 358 Closeout (Contract end date) Day 388. Total: 388 days reflects worse-case scenario pre-construction planning and then execution requiring no more than one week per building as GC must plan multiple locations occurring simultaneously. This project does not contemplate extraordinarily long lead times for any material, however, the GC may still experience unforeseen challenges, therefore, all material procurement must occur prior to mobilization to prevent this risk. Should the GC find that some items cannot be sourced and installed as planned here, then they must inform VA prior to mobilization, and revise their CPM schedule to show the longest delivery date(s) and adjustment of all activities preceding delivery of long lead items to ensure continuous flow of work through to completion (prevent false starts and delays). Part 3: Detailed Project Requirements: Project Objectives: This project is required to replace the described space and equipment as expediently and compliantly as practical. Meet or exceed all Code, technical, and programmatic requirements adopted, established, revised, and or published by VA or the many organizations listed in the several specifications. Expedite the delivery of a highly functional, complete, compliant, and safe workspace for the user service.
