Engineering fees themselves can be broken down into a few categories, each making up a percentage of the overall fee. Preliminary design services should be approximately 30 percent of the fees, while final design services and paperwork should equal another 45 percent. Construction and contract administration should be 20 percent, and tender call services should make up the final 5 percent.
The engineering fee percentage amount may vary depending on the complexity of the job and the percentage fee of the architect planning the project. For instance, Red Pepper Consulting suggests the fee amount to one-eighth, or 12.5 percent, of the architect's fee, or roughly 0.5 to 1 percent of the overall contract. A 2005 court decision upheld a 6 percent cap on a government contract for a combination of architectural and engineering services.
