Z2NZ--631-19-002 Upgrade Steam Distribution System Phase II Industry Day Recap

631-19-002 Upgrade Steam Distribution System Phase 2 Industry Day Recap Understand Challenges for construction regarding this project from a contractor s perspective. Is there any ability to alter phasing? VA Response: In-short, yes. As a result of your inquiries the project team is proposing phasing to turn over both basement and first floor wings coordinate well in advance to close, relocate, or adjust clinical operations for a fixed period. This includes a lengthy shut down of the canteen in summer months. This will allow more day shift work, more sustained/efficient construction avoiding nightly restoration. With careful planning and temporary heat provision plans by contractor this could also permit work during heating season. The solicitation will contain an updated phasing supplement by wings with permissible down time that shall supersede any specification or drawing phasing plans. We anticipate evaluating proposals with at least 1 factor demonstrating a contractor s utilization of these updates to indicate their time and cost savings relative to off-hours work. This supplement will also include operation constraints such as audiology and pharmacy where noisy work and infection control issues will push to off hours work. When is this project going to be solicited? VA Response: The intention is for this to be solicited late quarter three or quarter four. This presents an excellent opportunity for the awardee to utilize the winter of 26/27 to procure materials, complete admin and detailed coordination drawings for building 1, while utilizing immediately available work in buildings 15 and 16 to establish team dynamics, rhythm, and process to build steam. Are there any specific needs of the facility? Can a contractor utilize temporary heaters? Can a contractor bring in an engineering team to help assist? VA Response: VA would be willing to review these proposed methods. Again, the expectation is for a best value solicitation. The VA is highly motivated to complete this critical infrastructure. We will gladly review RFIs and evaluate tradeoffs. Topics so far we would happy to entertain: Value engineering proposal to change any load to hydronic. Rough sizing calcs demonstrating heating loads are satisfied Advantages: Copper/pluming work vs schedule 80 pipe welding. Significant pipe size reduction in mains, elimination of traps and maintenance costs long term, elimination of gravity dependent pathways. Elimination of smaller condensate pumps such as PTOT, customer care suite, canteen, mech room (still one in sub-basement), elimination of canteen CP by Walk-in. Savings proposals based on phasing supplement and temp heating to allow more winter work. Proposal to include products such as dryers and low maintenance sustainment. Any proposals increasing serviceable and low maintenance sustainment or energy rebate alternative ideas could be considered under best value Rathert than working above drop ceilings propose potential ceiling replacements if phasing supplement turns over. E.G: Canteen just demo drop ceiling to save demo and construction efforts, especially with ACM. Establish new IAW specifications. Propose net savings/cost trade off Canteen store drop ceiling replace Section of hallway leading to canteen, proposed elimination with cosmetic clean up Has the VA confirmed the pipe sizing and gravity of the system? VA Response: The VA has performed a qualitative review and directed drawing updates based on sizing. It is believed the current new work plan is largely oversized without being excessive, but to our knowledge no quantitative analysis exists. Is there any consideration to move away from the non-destructive testing? There are potential pitfalls in utilizing this method. VA Response: VA will look at this and review the methods. The current thought process is to establish minimal surveillance or critical areas where NDT including radiation exclusion radius/sphere will be performed off hours. This will likely be a hybrid...
