Please confirm if this brand falls into the category of "Approved Equal".

It can be mircom

63 Fire Alarm System E-502

Reviewing the Fire Alarm system operation index, the duct smoke detector only shuts down the associated air handler unit. Nonetheless, it is notorious that it doesn't activates the fire alarm system as a smoke detector or a manual pull station would. Please confirm if this is a mistake or if it will work as indicated?

The detectors are addressable, meaning they are intelligent and have the installation option. The detector must send a signal to the alarm panel, and the panel will send a signal to turn off the air conditioning units

64 Scope of Work Plumbing Please confirm if the furnishing and installation of the water heater is part of the scope of work.

Please confirm if the storage of the materials shall be in the project site or a location offsite.

The only things to consider regarding that note:

1- The existing wood finish floor that will be reused on this project.

Refer to reply on RFI 171.

2- The exisiting HVAC or other equipments that the STRI will keep are going to be unistalled by the STRI before the start of the demolition.

3- At the time of this Bid, the only elements that the STRI wants to keep are the (vintage - antique looking) Hardware of doors, closets and bathroom partitions. Prior the start of the construction a detailed list (inventory) will be provided to the contractor. The contractor shall unistall, storage and deliver to Tupper office this elements on boxes as clarify on the reply to RFI 123. The storage of this elements by the contractor is only until all elements has been completly uninstalled and a delivery day has been coordinated with the COTR. The storage location is to be determined by the contractor, considering that will be his responsability if any element gets missing. As a preliminary estimated amount of hardwares to have a general idea of the volume:

- Hinges of 20 doors @ 3 each = 60 hinges

- Panic push bars at main doors = 2 Panic Bars

- Hinges of 10 bathrooms partition doors @ 3 each = 30 hinges.

- Hinges of 24 closet doors @ 3 each = 72 hinges.

70 Architecture Windows / A-602

Our window provider comments the following: Can the window system for window V-05, V-07 and V-08 have a reduced width of 1.20 m to a maximum of 0.88 m. With these dimensions the insulation weight might not be a factor in the eventual malfunctioning of the balancer, due to these having a weight limitation. If the height and width were to remain the same, by experience, the balancers may fail by the wear and tear. The other option is the possibility of changing the system from vertical sliding (Single Hung/Guillotine) to horizontal sliding or exterior projectable window, with the dimensions shown on the drawings.

MAINTAIN DESIGN AESTHETICS, CAN BE EVALUATED LATER THROUGH

SUBMITTALS.

71 Civil C-104 In the civil drawing C-104, general plant of storm water system, the type B storm water box at the start of the 14.99 m line collides with the trench for the A/C piping. Please confirm if that will be the box's final position or it can be moved to avoid collision.

Pump

Our fire protection provider recommends that, since the fire protection pump specified is a vertical turbine pump, the water tank requires a pump sump at the bottom, which does not appear in the structure and architecture drawings. Please confirm if the modification will be performed to allow for the placement of the pump.

Bonds and insurance must be submitted as indicated in the RFP, 10 days after the project award, and must cover until the completion of the project, considering that construction will begin on July 14, 2025.

79 Scope of Work Material Prices

In the RFP Conference it was mentioned by STRI that the project is expected to begin in June/July 2025. If the contract is awarded immediately, will there be any sort of review of the prices prior to the start in case there is significant price increases in materials such as, concrete, steel, electrical cable, pvc, etc.

If necessary, the contractual regulations regarding price adjustment will be followed.

80 Scope of Work Submittals In the RFP Conference it was mentioned by STRI that the project is expected to begin in June/July 2025. If the project is awarded immediatly, will the STRI accept and review submittal information prior to the start of the project in order to allow for a faster excecution once construction begins?

STRI will accept and review submittal information after the Notice to Proceed has been issued.

81 Fire Protection F-502, F-504

In the fire protection drawings, there is a discrepancy in the fire pump specifications. In the drawing F-502, in the pump table the pump HP is specified as 60 HP, meanwhile in the drawing F-504, the pump description specifies a 50 HP electrical engine. Please confirm which of the 2 engine powers will be required.

THE PUMP MUST BE 60 HP, BUT IT MUST MEET THE PRESSURE AND

FLOW PARAMETERS, REGARDLESS OF ITS POWER.

82 Electricity E-601

During the August 13th site visit, the STRI personnel communicated that all electrical work was to be performed from the existing pole-mounted transformers onwards. In the single line diagram of drawing E-601, it is specified that "... it is recommended to replace the CTX21 - 3T -18GP1, for a conventional 3 x 75 kVA 120/208V ABC phases TX bank". Please confirm if the transformers are required to be replaced.

IT NEEDS TO BE CHANGED; THIS RECOMMENDATION IS DUE TO THE

REQUIRED LOAD AND HAS ALREADY BEEN APPROVED BY NATURGY.

THE REQUIRED TRANSFORMERS WILL BE INSTALLED WHEN THE WORK

IS NEARING COMPLETION AND SHOULD BE REQUESTED FROM

NATURGY AFTER THE OCCUPANCY PERMIT.

What would be the length of the stem? It is needed to be able to give a price to the pumps.

The length of the Turbine (if that is whats is getting ask on this Query) depend on the brand/model to be purchased and installed for this equipment. The contractor shall submit for approval a pump with vertical turbine, that comply with the design parameters of the pump indicated in the construction documents. The free high of the water tank per design is 4.45m + 20cm of the slab where the pump sits on, depending on the equipment that is chosed, if needed, minor adjustments for the correct fitting of this equipment will be provided.

In specification 210516 in point 2.3 it indicates the use of expansion joints for the fire protection system, but in the drawings there is no place that indicates that their use is necessary. Please indicate if necessary and indicate in the drawings the places and pipes that will be needed for these expansion joints to be able to take them into account in our assumption.

The use of the expansion joints recalled in the cited spec, depends on the need of having loop type connections. The use of a loop type connections could be changed in regards to the installer criteria; in which case, this spec will apply.

116 General General Is water and electricity consumed by the Smithsonian?

Yes, SI will provide water and electricity but the temporary facilities are responsability of the contractor.

117 General General Please indicate material specifications for perimeter enclosure

It is interpretated that the Query is related to the temporary perimeter fence for the construction.

If that is the case, contractor shall consider a perimeter fence to provide security and delimitate the construction zone. We recommend the contractor to consider a temporary fence to be @ 7 feet high, with double layer of low transparency Saran mesh (max. 30%), black color.
