Architects and building inspectors have never understood costs, building inspectors is understandable because we always take out our permits for a fraction of actual costs for two reasons, 1) keep our fees down, and 2) keep the owners' property taxes down. It's frustration with architect, their owners always want more than they can afford, or are willing to pay, and when bids/or prices come in the poor architects are always engaging in value engineering, in many times seriously compromising their designs. The last ADA I did was remodeling two baths to ADA standards 11 years ago, it ran about $70,000 (building permit over $3,000), removing old VAB flooring brings in the abatement contractors in space suits, covered walkways to covered trucks, and apparently taking the stuff by train to a huge canyon in Arizona (the last I heard). Now we have lead paint and Green Code recycling requirements as well.BTW, contractors' liability does not cover design professionals, when it comes to ADA the architect has to have his insurance company name the contractor and the owner on their policies as additionally insured, lots of architects' E&O policies are now refusing to do that, so we are limited to architects who have policies that will do that. If somebody does sue for an ADA violation my insurance will not countenance the lawsuit, I have to submit it directly to the architect's insurance carrier for defense . I did an ADA compliance a a large Catholic church once, several members were architects and contractors, none of them could provide the insurance for ADA compliance work, I was building a home near a committee member and he asked if I could do it? I submitted a proposal, their diocese attorneys, my insurance attorneys, and my attorney spent three weeks arguing over one word in the hold harmless and indemnification clause.
This is just the start of the paperwork, I then have to fill out multipage subcontract agreements with every subcontractor, before I allow any on the job I have to collect certificates of insurance from all of them naming me, the architect, and the owner as additionally insured.
