Hvac Design Proposal Documents 1

[irfansiddiqui]

I am Starting my career as a HVAC design engineer, i need to know that which documents should be attached with the submittal of the design?
Like
1. Load Calculation.
2. Schematic & Proposed Drawings.
3. BOQ
4. Specifications of Equipment.
5. Schedule of Equipment.
6. Approved Manufacturer list.

AND ?

Submittal to whom?

 

[irfansiddiqui]

to client

So assuming this is your final submittal before going to tender, I would provide all the above except for the load calc unless the client particularly asks for it and can understand it - perhaps just a summary table. Final budget and schedule should be on this list too.

thx

As "a client" what I want to know and understand is:

What decisions did you make?

Why did you make them?

Are the assumptions you made reasonable?

Are the calculations you performed correct?

Mint you deserve a star for the Punch questions!

To the OP,the most important document you need to send to your client is the Design Brief where all the issues Mintjulep has raised are answered.Your client should sign this off before you start any serious design work.If you know how to google,there are thousands of samples.

Depends on the customer, project size, and the standards. I think a lot of customers would want to see a LCCA with alternatives.

Having an Owners Project Requirements (OPR) signed by the Customer before starting design may be a good idea.

I think a client might also want to know how much it's going to cost, so an estimate might be expected.

If it's a renovation or expansion, client should want to see that availability of utilities has been addressed, unless you already consider that as a aprt of design.

There are four pieces that are typically submitted to the client:

1. Drawings: Full size drawings, hard copies, electronic, sufficient amount to send out to bid, permit or review.
2. Specifications: Complete specifications, same amount of copies to match the drawings, typically.
3. Cost Estimate: Full construction estimate for each bid item, if you have bid items. Typically, the estimate is split to match the sections of the specifications.
4. Basis of Design: This is exactly as it states, it is a basis of your design. What decisions were made? What was the basis of your decision. In this document you would include load calculations, manufacturer's catalog cuts, life cycle costs analysis, other engineering calculations (HW analysis, pipe sizing, duct sizing, fan sizing, pump sizing, etc.) Meeting minutes, owner's project requirements, a copy of the contract that you have with the client. I know this may seem like a lot, but a lot of these things do help out later, when the client comes back to you with some issues after construction is completed.
