Design - Quote
(OP)
I have been asked to put in a quote for a project where I will be required to carry out design (heatload calculation etc) as well as drawings. It will be a very basic system. There will be a couple of roof mounted toilet exhaust fans also.
The client has indicated underfloor ducting. I believe there will be 2 units required.
There are 2 buildings.
Building 1 is 3713 square feet (345 square meters).
Building 2 is 7750 square feet (720 square meters).
I was wondering if there is a basic formula to getting a more accurate quote? Say "X" amount of square feet (or square meter) per hour in design?
I am a bit torn over how many hours to put down in my quotation...
Thanks for your help,

RSMeans is updated every year with factors for project location and most of the variables are accounted for in the yearly realease. It's worth the $99 to get the book because, with a little study and work you can get the ballpark estimate you need from the publication.

60 hours a drawing
40 hours for spec
means books are way off

I would recommend for smaller project that 6% and 10% stated above not be used. For small project the overhead of setting up drawings, files etc is high compared to larger project.
The actual % of construction value may appoach 20%.
I think there is a lot of free engineering occuring on small project it is hard to even break even with the amount of time you spend on the job. There a no large peices of equiment to offset design time.
CME's hours per drawings may work better for you if this is a smaller project.
