I'm currently in an Estimating and Bidding class. I have to estimate two divisions for a multi-million dollar project. The project that I chose is around 6 million dollars and involves constructing a new gas/lighting building. I chose to estimate steel, and my question is, around how much out of the 6 million goes toward just the steel estimate? If it helps, this building is has two floors and is roughly about 100x70 feet. The building not wood construction, but rather steel and brick. How much of that 6 million would go into the steel? I'm not looking for anything exact, just roughly.
That is a little tough to answer given the details. I will try to answer it as best I can. You can send me a message if you need further help and I can get some more details from you. If it is a 6 million dollar project, that is about $428/sf - (6 million divided by 14,000 sf). $428 is a little bit higher end then say, just a Walmart which is a block and steel box. Assuming you have a concrete slab on the first floor, metal deck on the second floor, with steel beams and open web joists framing, steel columns and steel roof framing with a metal deck roof.... you could be approx 10-15% of the total 6 million. Now, this would include the structural steel, not light gauge steel framing for walls. It sounds like you are looking for structural steel, not metal stud framing. Hopefully this helps, I can check back to this thread later to see if you've had to add any more details.
It is not clear what stage this project is in. Is it preliminary or has a detailed design been done. It is also not clear if this is only the steel material or does it include the labor as well. A rough guess using a percentage of the total cost is okay if you have historical data to help you. If you have a detailed design then the percentage method should only be used as a check on a detailed cost estimate developed from the plans. If you plan to use numbers provided by someone here on Answers I would hardly call that an estimate.
