Project planning, CAD drawings, residential code compliance




(Located in West Michigan)
Formal project planning, drawings and prints are not absolutely essential for all projects.
Formal project planning, drawings and prints can be worth a truckload of building supplies if the following things are of importance to the project:


  • Identical drawings can be given to 2 or more different contractors for each to write and deliver a bid, in which you can then choose the most attractive bid to accept, knowing that each contractor had the same set of specific drawings to use to write the bid, which makes much less wiggle room for the contractor to try to weasel more money out of you for "mistakes" or "oversights" they may have made in the original bid.
  • The more thought that is put into a project and the more eyes that look at options before beginning, the less the chance of having the project run over budget, require mid-project redesign and change orders, be delayed while waiting for special order items or overlook labor and material requirements.
  • A task specific work schedule can be written up and followed as work progresses.
  • Formal prints and drawings can be used by any person that works on the project to communicate the exact intention and plans of any specific part, assembly or system of the project.
  • Verbal work instruction will be minimised, which leads to less miscommunication and error in the work being done.
  • Formal drawings can be used to settle disagreements between a contractor and the owner over work that was, or was not done as was originally intended on the drawing.
  • Drawings can be a permanent lasting record of mechanical, plumbing, and electrical work that might be hidden in floors, ceilings, or walls of the building.

I am able to make the required formal drawings, if you decide they would be of use to you or anyone else that will be working on your project. All drawings and system layouts are drawn and saved on a CAD system. All building assemblies and systems are designed and drawn to comply with 2006 residential code. Detail pages and views are included to more clearly show specifics about electrical, plumbing, mechanical, wall, cabinet, or other layout information.

The approximate cost for initial on-site meeting, discussion, measuring and photographs, a detailed work schedule work-up, CAD drawings that include plumbing, electrical, mechanical, and all other relevant sytem layout and notes, and as many sets of 8.5"x11"prints as you want is about $250 for a basic family or bed room layout, about $400 for a bath or laundry layout, about $600 for a kitchen/dining layout, about $1300 for an entire basement design, and relatively more or less for additions and minor/major alterations as required.

Residential building codes were not created to make your building and remodeling projects extremely difficult or an inconvenient "pain in the neck". The residential building codes are to be incorporated so that your building will be as safe as possible, durable, user-friendly, and comfortable.
