Building cost estimate factor (per SQM)

anyone here has a (not necessarily complete) list of factors to multiply to roughly estimate any building types? I specifically want to rough estimate an Entertainment hub, which has the following facilities.

* two standard cinemas (416 seater, 725sqm floor area each)
* Arcade games zone (2042 sqm floor area)
* childrens playhouse (326 sqm floor area)
* an event center (1226sqm floor area for stage and audience area, 421sqm for toilets, backstage, dressing rooms etc.)
* food court (938 sqm floor area)
* ice rink (926 sqm floor area)
* Science learning exhibit, e-games, administration, etc. (6870 sqm floor area)



thanks cgp,,,  

Pwede mong gawin, gamit ka muna ng 30k/sqm na construction cost for all. tapos patungan mo ng extra cost ang mga kailangan na space...

like

1. cinema + 50k-70k/sqm for acoustic and equipment
2. arcade + 30k/sqm for equipment
3. playhouse + 10k/sqm for equipemt
4. events place, foodcourt, science + admin - as is (add mo nalang sa science ang mga items na kailangan.
5. ice rink + 100k/sqm siguro sa equipment nyan.

These are all assumptions lang. kailangan mo talaga ipaquote ang mga equipment para makuha mo ang good number/factor.

good luck!
