11. Per General Construction note 6 on drawing C0.1, it states that the contractor may have to excavate and replace unsuitable soils if encountered during the site work activities. We will need a Geotech report stating where these soils might be so we can determine how much import and depth we will have to excavate per the geotech report recommendations. Otherwise, this will have to be done with a Mod to the contract after award since we cannot determine these conditions without a geotechnical survey and report.

See added Specification Section 02 30 00 with attached Geotechnical Report.

However, it doesn’t state that we are to demo these areas in the demolition drawings.

For the concrete integrity, we recommend removing and replacing the concrete in these areas so we can reinforce and dowel into the existing SOG. Please provide guidance for this scope of work. We also need reference detail cuts that refer to a detail drawing for each area that is receiving new concrete flooring.

Slab cut areas can be increased at Contractor’s option for no additional cost to the Owner.
