Questions & Responses

Question 1. Sir, upon reviewing this project scope and bid form. I am trying to confirm you are asking for a 6month rental agreement and leaving the chiller onsite and out of use the remaining

6 months? Or are you looking to rent this chiller for an entire year?

If this is only a 6-month rental period, we would have to pull this chiller at the end of the 6month period to be rented elsewhere through the winter and reconnected at the beginning of the next summer.

Response 1. The operational status of the chiller shall be 6-months of the year and the other 6-months shall be winterized and sit on-site until start up the following ordering period (See

Section B.4 (1) of SOW/Solicitation. The initial set-up would be the first year of the contract and the decommission would be the last year of the contact. The end of the base year contract and the middle years would just need a startup/unwinterized and a standdown/winterized of the equipment.

Question 2. Will the chiller/tower/pumps be removed and reinstalled at the end of cooling season each year and stored? Or will everything remain in place and just be winterized/shut down at the end of each cooling season?

Response 2. See Response 1
