One of the basic problems in housing construction today…in terms of achieving the cost benefits of assembly-line efficiency…is that not enough houses are built at each building site to allow trial-run debugging to extend or project itself over tens of thousands or hundreds of thousands of identical products.
For most housing construction projects, after all of the construction problems are resolved…the construction is complete…the house is built…and we move on to a new and different project.
Problem-solving and debugging are an integral part of every new housing construction project…usually from start to finish…because the same product is not repeated in large enough numbers to “build” upon pat experience to the point of assembly-line perfection.
An assembly-line approach cannot be used because of the practical reality that houses are too large in size to be fully assembled at one location and then transported overland to another. Each new house must be assembled piece by piece at its exact location on the building site…and because houses occupy space…only so many can fit on each project site.
Each new housing construction project is therefore a one-time event…limited in duration by the total number of houses to be built at that site. Each project is separated from other projects by the distance between building sites…along with the economic competition between rival construction companies.
New housing construction projects have only one opportunity for defensive, proactive problem-solving and assembly-line debugging. Builders, subcontractors, superintendents, forepersons, and tradespeople must be prepared ahead of time to debug the individual peculiarities of each new housing construction project…or suffer the consequences of schedule delays, cost overruns, and dissatisfied homebuyers.
Like baseball, basketball, or football games…new housing construction projects must have both a defensive and offensive game-plan to achieve success.
