Hi,虽然工程管理扩展成本可能比较低,但尚不确定组织和协调行业并不像你想象的那么容易,并常常导致工作拖累加成本加打乱家事可能非常令人沮丧
希望这有帮助

我总说让全项目由一个承包商完成比较便宜取全项目价钱 而不是冒风险 在不同时间从不同行业获取不同报价
未来交易准备就绪时 高包商会计划这一切
hope帮助 :

as pep said use a main contractor who has good subcontractors already he can give a cost quote not estimate and what they will build for that as by doing it yourself you will not know the speed in which each trade should be working and can cost more in the long run also if they quoted they need to do the work stated in the quote for that price if it takes for instance 4 days to do something rather than 2 you dont have to sort the extra cost the contractor swallows it if no main contractor you will be paying trades extra each time a little problem holds them up.
its also very stressful I know I am a main contractor but I work out all the materials everything no matter how little the quantities the cost when to order for the right time when to inform the next trade to come in how long it will all take and you may think online has these answers it never works like that the prices are inaccurate online its says cheaper than builds really cost says bricky lays 1000 a day usually this is not possible they may lay anywhere between 350-1500 in a day which is a massive difference in timing and therefor cost overall.
