The electrical schematic diagram indicate the connections of the new service line to an existing panelboard in the electrical room of the existing main building. We request that you include a scale plan indicating the location of the main building and the electrical room related to rest of the Project. We request that you include the technical information of the existing board and the existing switch. We request that you advise which of the two NC-1 note options applies. If posible we require an inspection of the existing electrical room.

Refer to revised sheet E-100 PDF files "1680001 E-100 (R1)"

2 FIRE PROTECTION F-501

The Detail only show the installation of Gabinet and Valve for firefighters, only this is what need to be installed in the cabinet?

Yes, this is the proposed and approved detail for this project.

3 FIRE PROTECTION F-501 The drawing does not show the design for a gravitational block and only thust block for a 4” pipe design. Send Design for the pipe to use which our case is 6”

Refer to Schedule updated on revised sheet F-501. PDF files "1680001 F-501 (R1)"

4 FIRE PROTECTION F-601

Drain Valve specificationsis required. In Drawing F-101 it show the drainage in the Gardening room, but it does not show where it will drain.

The valve to be a ball valve, it will be used as a threaded hose when needed to be used for the drain of the Fire sprinklers.

5 PLUMBING P-001

Is there any specifications for the for the toilets / accesory schedule in terms of brands . Plan P-

001 note 16 indicates that all material to be used shall be by the same manufacturer, but we see no model, brand or manufacturer mention for the plumbing artifacts (toilets, sinks, faucets, etc.)

on the plans. This is information is not mentioned on the specification either. Please indicate the models and manufacturers desired for the plumbing artifacts to be included.

Refer to revised sheed A401. For the emergency shower consider the following specification: HAWS

MODEL 8133H and for the floor drains on the workshop area: tramex Floor drains.

PDF files "1680001 A-401 (R1)"

6 PLUMBING P-601

Which is the specification for the Emergency Wash Shower, it only appears "Hawsco", but there is many material finishes, also to know if we can submit and alternative brand

During the execution of the project the contractor can submit using a subtitution form an alternative product that complies with the original specification or exceed. Refer to revised sheed A401. For the emergency shower consider the following specification: HAWS MODEL 8133H and for the floor drains on the workshop area: tramex Floor drains.

7 GENERAL ADA

We understand that this is a "workshop area", but in the toilets case, the documents request to comply with ADA, the question is about specifications for the faucets, flushometers, or bars

(because we don´t visualize it in the drawings)

Refer to revised sheet A401, for revised information of all the fixtures and accesories. Because of the characteristics of this project it wont comply with ADA.

In the Plumbing notes point No.5 it is indicated that the nominal dimensions of the pipe are copper type L. It is considered copper pipe for the installation of drinking water or there is the optionof using another type of material

For this project shall be consider the use of CPVC for potable water system and shall comply with division 221116 of the specification document of this project.

In notes on Plumbing Point No.15, it is indicated to insulate the cold water pipes (drinking water). This requirements will be applied to entire route of the pipe within the Building?

The potable water wont be insulated.

In the notes of Hydraulic code point No.4 it is requested to install vacuum arrestes on all taps and other hose connections. These are contemplated in its Design (Isometric)??

To be use only for exterior faucets. The faucets can inclued also an antisiphon system.

In the minisplit capacity chart it indicates that the total MS-1unit 9ea is 12,000 Btuh,however, the model indicated is “ VR242CW” corresponding to an air of24 000 Btuh, in the same way, the MS-2 unit total 1ea, they are24 0000 Btuh and the indicated model is VR122CW corresponding to an air of 12 000 Btuh. We require that you indicate capacity for the MS-1 and

MS-2 units.

The models have a mistake in their descriptions, The unit MS-1 is 12,000 BTUH, and the unit MS-2 is

24,000 BTUH. Refer to revised sheet P-001
