Concrete Slab Ques�ons and Answers

Q1. The SOW indicates that six inches of material are to be removed, but it also indicates that six inches of concrete are to be poured on six inches of drainage material, such as crushed rock and gravel. Request clarifica�on, as this actually implies 12 inches of material to be removed – six inches of drainage, plus six inches of concrete.

A1. 12 inches of material should be removed prior to placing 6” of base and 6” of concrete.

Q2. Do you want to facilitate drainage by way of fall/slope only, and if so to where? Or do you want a dry well or another solu�on?

A2. Site currently drains predominately to the east away from the building and does not have any drainage issues. New slab should also drain away from building. No addi�onal drainage such as a dry well are part of the project.

Q3. How long can the condenser – currently set on the ground toward the north end – be taken offline for work to commence?

A3. The condenser on the east exterior (that runs the two mini-splits in the adjacent offices) does not have a maximum dura�on for which it can be offline at this �me. A good-faith effort to minimize down�me is sufficient.

Q4. Do you want any repair done to the concrete pad/founda�on that meets the proposed/required pad, or simply lay the pad and leave the current concrete in its current state?

A4. Repair loose concrete, spalls and cracks in building slab within 1’ of new concrete. Use manufactured sealants and patching compound for intended use.
