While I'm reading AHPP, Chapter 10.7 Construction Specifications, I'm just curious about each party's responsibility related this subject.
In the book, drawings must be coordinated with the specifications to minimize confusions and to avoid excessive change orders. Excessive change orders are a result of poor coordination as follows,
- Specification phrases that say 'as indicated in the drawing', but no reference on the drawings
- Drawing phrases that say 'as indicated in the specification', but no reference in the specification.
- Specification that included materials that are not required for the project.
- Drawings that indicate materials, but they are missing from the specifications.
- Specifications that indicate a specific type of materials, but the drawings indicate another.
My questions are,
- What if these poor coordination cases happen, then which party will take a responsibility?
- For example, architectural drawings don't show door hardware in residential project. But architect includes door hardware information in the specification. The contractor request a change order to the owner for the door hardware because the hardware is not showing on the drawings. Then who is responsible for the door hardware cost?
I thought that the Contractor has to cover the door hardware cost. Because the drawings and specification are Contract Document between the Owner and the Contractor. Even the Architect missed the door hardware on the drawings, the Contractor has to supply materials as addressed in the specification. Is my understanding correct?
