Please join us for our November Chapter Meeting as we discuss Mix Designs!
WHY MIX DESIGNS?
If you are in the Construction industry…you will probably deal with Concrete or Masonry Grout Mix Designs.
We plan to bring experts in each stage of the Mix design from Start to Finish. Why do we have mix designs? What do they do for the projects? How does it impact the project?
Communications between the owner/Architect, Geotechnical Engineer, Structural Engineer – Designing-Reviewing-Inspecting, General Contractor, Supplier and Testing Labs play a key role in the success of a project with a proper Mix Design.
OUR PRESENTERS:
Steve Nowaczyk - Geotechnical Engineer – Ninyo & Moore
Who hires the Geotechnical Engineer - Owner/Architect?
What is the procedure to gather the Geotech information for the project?
The Geotech would also be scheduled to take samples for the Testing process, which will be transported to the Geotech Lab when ready.
Geotech Lab would submit findings to the Supplier for recording and compiling current Break History.
How is this information put together and where does it go?
Daniel Van Cuyk PE,SE - Structural Engineer – Caruso Turley Scott
What does the Structural Engineer look for in the information from the Geotech?
How does the Structural Engineer use this information for His/Her design? And how is it noted in the Structural Drawings?
What if there is no information available from the Geotech Engineer?
Jeff Miller - General Contractor - Sundt
Contract Documents received by General Contractor. How does the GC know what Concrete Strengths to order from Suppliers? Review Mix Design and coordinate with the supplier for placement.
Who from the Supplier do they contact?
Lauro Rivas - Supplier - CalPortland
What information does the Supplier use to forward Concrete Mix Designs to the GC?
After GC receives the Concrete Mixes from the Supplier, they are forwarded to the Structural Engineering Team for review.
Sheila Hall - Structural Engineer – Shop Drawing Review – Caruso Turley Scott
What criteria is used to review Concrete Mix Designs – and Grout Mix Designs? ACI & ASTM C-476.
Why are some Mix Designs marked up – or rejected?
Reviewed Mix Design submittals are stamped by Structural Engineering Team and returned to GC
Bryan Castles P.E. – Western Technologies, Inc. - To talk about the newly updated ACI-211 Document, and also give a perspective from a Mix Design lab.
