MEP design and BOQ

I need to do a detailed MEP plan for a hotel project. We have a rough plan already done, but need expert inputs on material specifications, calculations etc on electrical and plumbing systems. and make final cad files which can be read by constructor on the ground and construction supervisor. Most of structures are tented camps, some are construction, everything is single storied, its a big area. The basic siteplan and structural designs are already done.
