I am developing a construction schedule for a power plant project. Project is in early stage and we do not have any construction manager to assist with the planning effort. I have man hours for all major activities and now I need to convert those manhours in durations. I need to know the standard size and mix of crews for major construction disciplines e.g. Piling, foundations, earth work, Piping, mechanical, electrical and insulation. Is there any body who can guide me about this issue? How can I find this information? Is there any data book or website?
Thanks
