Yes, that is the intent. However, it was anticipated that multiple valves and the piping between the riser and the valve could be replaced while the riser is drained to reduce the number of outages. The piping on the AHU side of the valves can be replaced at a separate time if need be to reduce the number of outages. Hot tapping in new connections is not the preferred solution. Can you provide the dimensions for the mechanical room doors? 3' X 8' Can the door frames be taken out to allow larger sections to go into the mechanical room? Yes, but they will need to be re-installed prior to normal business hours on the following business day. Given that JCI is basis of design for air handling units and they are the sole provider for the building automation systems, will they be given an allowance for the BAS portion of the AHU replacement? If not, there will be no way to receive competitive bidding on the air handling units for this project. No allowance for this. There are multiple licensed distributors in the Houston area that could also perform this work. Can a dumpster be staged at the UCT building for the disposal of demolished AHU’s and other building materials ? Yes, the dumpster will need to be placed in the IMM loading dock between UCT and IMM. Can the tenth floor architectural scopes be performed on the weekends, and who is responsible for protecting the existing furniture and computers in the construction site while said work is performed? All work on the tenth floor will need to be done after hours or on the weekend. The contractor is responsible for protecting furniture and property in the offices and cleaning up all debris after the work for that day is complete. Level 10 IAQ Scope – Drawings indicate the electrical LED lighting replacement, spline ceiling replacement, replacement of duct taps, and new emergency circuit panel all are shown as part of the base bid; however, the schedule of values is asking for these to be alternates. Please confirm whether these scopes are to be priced in the base bid or as alternates. LED lighting replacements are under the alternate. The new emergency circuit panel is part of the base bid. Does the outside AHU need to be re-built and up and running over one weekend or it can be spread out over multiple weekends ?
Confirm the AHU’s can be run in “hand” and do not require full control by the Building Automation System? The AHU's can be run in "hand" on Monday morning, with controls installation and set-up to follow that week. Confirm the existing fire alarm system is Simplex 4100 V? It is Simplex 4100U. Confirm the elevator does not provide access to the roof or penthouse and the only walkable access is through the flight of stairs from the 26th floor. Confirmed. Confirm all existing AHU’s are externally spring isolated without base rails. Confirmed. Will the replacement units be placed on external spring isolators, directly on the floor or on a concrete pad? If on concrete pad, please indicate the designed height of the pad. If on external spring isolators, confirm that internal isolation of the fans is not needed. If the units are not placed on external spring isolators, confirm that internal isolation of the fan is required. Additionally, confirm that the AHU manufactures are responsible to increase base rail height in order to accommodate trap height. New AHU's will have baserails and shall be installed on neoprene waffle isolators. AHU manufacturers are responsible for increasing base rail height in order to accommodate trap height. Confirm the location of the multizone dampers, are they to be duct mounted or factory mounted on the AHU’s? Duct mounted at AHU discharge, and coordinated with ductwork. Clarify the timeline for the AHU field leakage and deflection testing. Is this required before starting up the units on Monday Morning? No. This is required prior to substantial completion.
