QUESTIONS & ANSWERS

Questions and Answers posed:

This solicitation initially asks for 56 CY’s of a 4500 PSI SCC mix. I assume this 56 CY’s is one placement?

o Yes, the 56 cy is for the downstream sill beam placement.

You then have additional options of 10 CY’s. Would these be the same day or alternate days?

o 10 CY as needed.

Pumping asks for a 200’ in minimum distance in length. I am assuming you are OK with Hose on the ground like we did the past for LD4 (JF Brennan as example) As the largest truck mounted pump by putzmeister for example has a horizontal reach of 190’7” ???

o USACE prefers a truck mounted pump with the longest boom horizontal reach. If a greater distance is needed extension hoses attached to the end of the boom would be acceptable. USACE will have a crane available to support the hose extensions.

o And As I am sure you are aware these are not common and would be traveling to get to LD4. Yes Would the USACE do the concrete construction end of the work (i.e. Placement) or is the supplier on the

Solicitation required, or would and should be partner up to complete this? ???

o USACE personal will be placing the concrete.

#1 – Concrete Mixture – 4500 PSI SCC – In the Cementitious Materials 2.f. – it says optional replacement of pozzolans is 25% Maximum, Silica Fume is 5% Maximum – I would be proposing a mixture that we have now used on LD 6,8, and 9. That has a high replacement of Slag @ a 1:1 Ratio with Cement. I am assuming that since this is not listed I am OK with this.

The specified concrete mixture is intended to create a hard, dense, abrasion resistant surface #2 – I am unaware of what the downstream bulkhead sill beam is exactly and where that is located.

Please see the attached PDF (Attachment 1) #3 – Reason I ask #2 – Is where would the pump need to be placed in the USACE’s “mind”?
