For cutting costs, some of the clients told me they could supervise the construction site by themselves without me being involved, I found it very amusing and thought the home remodeling TV shows and the big building material supply stores really poisoned the consumers with DIY very well.
Many consumers don’t know how to read technical drawings such as schedules, elevations, sections, and details, without the knowledge of understanding technical drawings, how possibly they can know what the builders are doing on site? Those fancy 3D perspective color renderings look nice but really don’t tell you that much. Even for those technical savvy consumers who know how to read the technical drawings, one thing they will never know is that when they see the workers were installing base boards or door casings, if it was the accurate timing for such tasks?
Some builders and contractors don’t prioritize the tasks correctly due to lack of understanding the design details, so they might look like they have been working hard at the job site, but the tasks they performed might not be proper for that particular timing, and no any drawing will tell you that.
For example, I once designed a double swing door using floor and ceiling recessed mount pivot hinges for a project, and the door stop for that door was another piece of millwork right next to it. The contractor wanted to show the client some progress, so he quickly asked the millwork shop to install the millwork that also served as the door stop and also asked the painters to paint the walls and base boards around the millwork without installing the door panels first. The client went to the job site and saw the workers were working very hard so he felt happy since he saw “the progress”, then he returned to the job site a week later and saw all those installed millwork and base boards had been taken down. It turned out the contractor had to ask the millwork shop to take everything down because he needed to have the slab fabricator cut the floor slabs for installing the swing door’s pivot hinge on the floor. The painted ceiling also needed to be broken in order to install the other pivot hinge on the ceiling, and the walls near the millwork had to be re-painted because the walls were damaged when millwork people tried to take down the millwork, and because the wall finish was eggshell which could not be touched-up partially, the entire walls in that area needed to be re-painted. The worst part was the walls were spread painted, so the painters had to spend the entire day just to tape up the plastic wraps to protect other installed millwork in the same area before they did the spread paint. One step forward, ten steps backwards. This is the best example not to DIY the job site supervision.
