I usually include them in the other sections depending on subject, but what happens when moving a plumbing drain and there is no Concrete spec section included in the Project Manual? What have others done? ken hercenberg Senior Member Username: khercenberg Post Number: 815 Registered: 12-2006 Posted on Thursday, August 14, 2014 - 10:02 am:    Unless you want something different, like non-shrink grout, my spec defaults to a "patch to match" clause. Essentially whatever you take out, you put back. If they're cutting new construction it's easy; I typically require that they engage the original installer to repair the damaged surfaces. If renovating existing, our best guess may not be accurate so I require the contractor to determine what was removed and put back equivalent product. If appearance matters, you need to include a requirement that finished appearance is subject to review by architect. Jerome J.

The work is a renovation to an existing building.

The requirements have been imported from technical sections, but w/ somewhat less detail since the applications are usually limited. The applications include concrete (including CIP, concrete patching material, and cement-based underlayment); msry patching & alterations (including incidental repointing); stone wall base, waterproofing, EIFS, roofing, fireproofing, gypsum plaster, cement plaster, and terrazzo.

Then cutting and patching, which is sometimes included in Execution, can rely on the the other sections. Jerome J.

This is new to me, usually there is a Structural Engineer on the job, but not on this one - I am doing the specs as a favor to an Architect friend, its such a small job, teaches me for doing a favor, the job is taking way too long to finish.

Plumbers and electricians are notorious. Thus there is a need for somebody to review what was done and whether you need to involve a structural engineer.
