Structural design and drafting quotation
(OP)
Hi Gentlemen,
recently I got an opportunity to design a 5 story residential condominium.
The developer is a friend of mine and he wants me to do the structural design and drawings.
The existing project includes a 4 story residential condominium on one story concrete slab on concrete columns.
This condominium is more than 8000 Sq.ft
Now the question is that how much is the cost of design and drafting per sq.ft?

Is there anybody helping for this price with or without drafting?

I have always quoted project fees three ways and averaged my bid based on the current market and my costs. Sometimes I passed. Many times I did not get the project.
1. I went by a straight percentage of the estimated cost of the structure, considering e3ngineering, drafting (or the lack of it), the complexity, size, and repetition of structure. These are gut calls based on experience.
2. I would itemize and assign ho9urs and hourly rates to all the different tasks and sum up the total, and
3. I would figure up the number of drafted sheets that would be needed for the project, assign a $ per sheet value, and sum the total.
Then I would look at all three and determine what I thought was reasonable. If they did not like it, I would move on. Never dickered.
Quite frankly, If I heard that others were bidding on the job, I would either refuse to give a bid for whatever trumped-up reason, or just give a very high number without taking my normal time to create the bid. Surprisingly, sometimes I did get the job.

I never had my own company, but one of the commercial/industrial consultants I worked for had the same three methods of estimating. At the project estimating level we had to do 2 of the 3 and compare before sending it up for the Principal's to review/approve. I generally chose 2 and 3 from above. If they gave greatly different numbers, we then added the 1st method in before sending it on.
I've kept hours/drawing documentation since very early in my career. So number 3 becomes matching the hourly rates of the team members to the anticipated drawing hours. Number 2 requires some thought as to the steps required for all of the different parts of the project (building and equipment being supported). This only comes from experience.

The sq.ft rates only work on larger buildings, they are very inaccurate for smaller complex buildings. we use % of estimate build costs as our first ball park and work from there with hourly rates.

The guy is asking a tip website on how to price a project. He can't be further helped.
