Architects, Engineers, Property Owners, and Other Important People: Job Planning

All of us in construction are familiar with the "I did it per the specs" excuse. It is when the job has went south and a reason must be found as to why- so finger pointing begins. The problem is often the job specifications and the product specifications do not coincide.

Architects specifications are often boilerplate and transfer from one job to another- even when job conditions are different.

Contractors are busy and bid many jobs- often with no time, or due to distance they are unable to examine the project specs versus the product specs and job conditions.

Owners often just dont think it can be that complicated.

Smart owners, property managers, and designers will start at the end, considering the desired result and ask", what is the end result of the new floor we are looking for"? Review reputable products that will produce that result.

Then write the specifications following the product manufacturers instructions for installation and considering the job conditions.

The above is not an easy task- but it beats the blame game that occurs when it is not done.
