| What is new in ACI 301-20, Specifications for Concrete Construction |
| |
|
The American Concrete Institute (ACI) published ACI 301-20, Specifications for Concrete Construction, in October 2020. This standard specification establishes criteria for concrete construction that can be incorporated by reference into contract documents. ACI 301 is written to the contractor. When an architect or engineer (A/E) cites ACI 301, the document is intended to be adopted in its entirety into the contract documents. Requirements set forth in ACI 301-20 meet the minimum requirements in ACI 318-19. |

Submittal checklist |
|
Does anyone use a checklist for which submittals and submittal types are required for individual items on a project? My plan is to provide a checklist for the design teams at the start of the project. If anyone else is doing this, what are you including as options, and does it work well with your teams?

| Contractor responsibility to specification in bidding |
|
Looking for insight on this situation. Specification lists 3 manufacturers and product requirements (along with drawings). Contractor put one of the manufacturers in the GMP (presumably they got bids through a sub using said manufacturer). The shop drawing submission changed the product requirements significantly and the Architect rejected them and stated the appropriate requirements (quoting drawings and specs). Manufacturer then stated they cannot meet the requirements. Contractor then went to another manufacturer listed in the specs to get the product. Contractor has now submitted a 50K change order for switching the manufacturer. Is this a valid change order to the owner? |
