As DSB123 pointed out* companies estimate man-hours based on their own experiences. For instance a company like PDVSA* Venezuelan oil company* has a manual (if you speak spanish I could sent you a copy) where stablish for the type of engineering your are going to do (Conceptual* Basic* Detail) the typical documents and drawings required by each discipline. With that* and some criteria of your own* such as determining how many Process Flow Diagrams (PFD´s) for instance might be required to a certain job* you estimate the man-hours. In the company whre I work* a engineering consultant* that is done by senior engineers of each discipline (Process* Mechanical* Electrical* etc). You as coordinator put al the man-hours togheter and estimate the staff hours such as Project Manager* Engineering Coordinator* Planner* Contract Administrator* Cost Estimators* etc. Many of those are full time* some are partial time* as might be the case of cost estiamtor* which is required once youa have sized the main equipment or bill of materials* depending of the type of engineering.
Other thing is determine the categories of required engineers* based on their experience. The more early stage in engineering* the more experienced engineers you required. For instance* for a conceptual engineering* you might require more experienced engineers* as more design criteria is required. Also for man-hours estimates you have to use judgment* as a more experienced engineer can develope some task more quickly and efficiently that a les experienced one* but is more costly.
So my dear friend* there is not a rule of thumb or a clear cut way of estimating man-hours for a project. Even some companies estimate engineering man-hours based on the number and type of equipment. And as DSB123 said* you almost always underestimate. Worst if you are competing against other engineering companies.
Based on you requirements I posted the book Engineering & Construction Project Management - A. Kerridge (Gulf Professional Publishing* 1986)* where chapters 14 and 15 explained some methodology for estimating man-hours.
Againg for your benefit* I will be uploading another book with more information* but in a different thread to benefit more people. The book is Planning* Estimating and Control of Chemical Construction Projects (2nd Ed.) - P. Navarrete (Dekker). Look for it.

Dear Gusgon* any chance you can share with me the PDVSA book please?
Regards.
