75 06/05/20 31 56 00 2.1.1 Specifications Section 31 56 00, Paragraph

2.1.1 states that the slump for concrete used in the slurry wall shall be a minimum of 7 inches and a maximum of 9 inches. It is our experience from many slurry wall projects all over the world that the slump flow value is better suited for measurement of workability of tremie concrete used in slurry walls.

We respectfully request

The original slump requirement of 7" to 9" is consistent with the "Industry Practice Standards and DFI Practice Guidelines for Structural Slurry Walls" published in 2005 by the Deep Foundations Institute.

However, this was published in 2005 and does warrant reconsideration based on newly accepted industry standards.

ASTM C143 notes that for slumps the specification to allow an alternate to slump by using a slump flow value of 21" ±2".

Should the Government object to the usage of the recommended slump flow value, we respectfully request the Specification to be amended to allow for a maximum slump value of greater than 9” greater than 9", the typical slump test does not provide significance. Agree that slumps greater than 9" are more accurately measured using the suggested slump flow value.

The request for 21" +/- 2" is on the very high end according to "Guide to Tremie Concrete for Deep Foundations" by the joint EFFC/DFI Concrete Task Group.

Slump flow value as a means of providing slump testing will be permitted, but the allowable slump flow shall be 19" +/- 2".

76 06/05/20 31 56 00 3.5.3.1 Specifications Section 31 56 00, Paragraph

3.5.3.1 calls for airlifting of the slurry wall panels 1 hour immediately prior to placing concrete. Since the excavation will be carried out with a trench cutter type equipment which utilizes a powerful submersible pump to remove the cuttings and subsequently clean the bottom of the excavation, the requirement for airlifting is not needed.

Furthermore, the specified requirement would mean airlifting while the cage is already in the panel.

The best practice is to proceed with placing concrete as soon as the cage is in without further delay. We respectfully request that

Since the excavation will be completed with a trench cutter type equipment and is predominately in rock, the requirement is revised.

Consider the requirement to clean the bottom of the panel by air lifting within 1 hour removed from Section

3.5.3.1. However, the

sand content measured 12" above the bottom of the trench within 1 hour of placing concrete will still need to meet the necessary requirements.

Furthermore, consider "Step A" of Section

3.4.5 reworded slightly to ensure the panel is cleaned by hydromill equipment within 24 hours of this requirement be removed from the Specifications.

concrete placement.

"Cleaning of panel must be done by hydromill equipment or other approved method. The cleaning operations must be completed within 24 hours prior to initiation of concrete placement."

77 06/05/20 31 56 00 2.1.1.1 Specifications Section 31 56 00, Paragraph 2.1.1.1, the fly ash content in cementitious material is defined as 10 to 15 percent.

Is it possible to increase the fly ash proportion of the cementitious material to 35 percent or alternative slag proportion of the cementitious material up to 50 percent?

Per PPI Response # 39, the maximum fly ash content in Section

2.1.1.1 of 31 56 00 is changed to 25 percent. The maximum fly ash content is further revised to 35 percent in Section 2.1.1.1 of 31 56 00 per request.

However, consistent with notes on Drawing LPS-S-101, the concrete used in the slurry wall shall be shown to have a minimum compressive strength of 5,000 psi at 28 days.

The use of Ground Granulated Blast- Furnance Slag (GGBS) conforming to ASTM C989 for a portion of the cementitious material will be accepted. The maximum percent of total cementitous materials by weight including fly ash and GGBS shall not exceed 50 percent.

for subsurface information.

Compensation for removal, disposal and replacement of unanticipated unstable and unsatisfactoray material will be evaluated if encountered.

79 06/05/20 22 31 00 00 3.9 The specification states to stockpile and use coarse rock from excavations for constructing slopes or embankments next to streams.

Is the intent of this specifation to utilize all the rock from excavations on site?

Utilize excavated material where suitable and can meet specification requirements for general site fill, embankment slopes or stream bank protection. Transport approximately 12,000 cy to the designated stockpile location on Base. The remaining excess must be removed from the base.

80 06/08/20 Sheet 358 Volume 3 Drawing

On drawing OSB-S- 202/ C1 calls for double angle braces but calls out for L6x4x1/2x3/4LBB.

How thick is the angle?

This seems to be a typo.

Also similar notation are used on other structural elevation drawings like WHS-S-

201, WTB-S-201,

MEB-S-201.

Please clarify?

The double angle braces in the OSB, WHS, WTB and MEB follows the notation "A"x"B"x"C"x"D", where "A" and "B" are the lengths of each toe of the angle, "C" is the thickness of each angle, and "D" is the spacing between the two angles. Details OSB- S-505/ C1 and C2 show the 3/4" gusset plates and intermediate spacing plates that will be placed in the gap between the angles.

Drawing LPS-S-137 Slab Plan shows a longitudinal construction joint and optional transverse construction joints (see Note 3). NOTE 3 states "At the Contractor’s option, transverse joints may be used in the slab.

If using transverse joints the slab shall be placed in 8 pours with with joints placed at a maximum of 42 ft".

Is the intent that the base slab shall be poured either in 2 or 8 pours and no other combination pour combination allowed?

Please confirm.

The intent of the note was that the slab would be poured in either 2 pours or 8 pours. However, other combinations of pours, such as 4 for instance, utilizing the transverse and longitudinal constructions joints shown on LPS-S-137 would be approved.

The thermal modeling and thermal gauges required for mass concrete would have to be consistent with the selected slab pouring sequence.

UTF-C-003 shows that all the concrete (slabs on ground, footings, retaining wall, and other concrete including piers) is 4,000 PSI.

However, in OSB-S- 003, it states in the concrete material schedule note 2, that exterior concrete applies to stoops, aprons, equipment pads, etc. Outside the building envelope that are exposed to weather to be 5,000 PSI. Is this the owner’s intent to use 5,000 PSI only shown on the building concrete drawings?

The exterior concrete shown on the structural building drawings shall comply with ACI 318-14 requirements for exposure class F3 (concrete subjected to deicing chemicals), which requires 5000 psi strength -- such concrete includes door stoops; slab on ground below Warehouse canopy;

WSA foundation; and FPE foundation.

A3 Is there a specification or detail on the construction/assembly of the hardwood crane mat sections?

The crane mats shall be purchased from a Crane Mat Manufacturing company with a minimum of 10 years experience fabricating hardwood crane mats.

The mats shall be solid hardwoods or oak and delivered to the jobsite pre-assembled. The detail indicates 8' wide but 6' wide would also be acceptable.

133 06/08/20 33 32 13.13 1.3 The 4th paragraph states 'approved equals' shall be submitted for approval 15 days prior to bid date. There is no basis of design manufacturer listed for the pumps nor a list of acceptable pump manufacturers. Please provide both the basis of design pump manufacturer and approved equal pump manufacturers.

Design Basis for the Grinder Pumps - Make: Sulzer; Model:

Piranha PE100/2-E- 60 Hz, proposed approved equals must be submitted for approval.

134 06/08/20 Geotechnica l Report

It is not clear if the Geotechnical Design Report prepared by Jacobs/Terracon, Underwater Launch Test Facet, dated February 28, 2020, is a Contract Document.

Please clarify. If it is not a Contract Document, please identify the technical data in the report upon which the Contractor may rely.

Yes, it is a contract document

136 06/11/20 13 and 14 31 00 00 Page 13 a. Slurry Wall Protection indicates the contractor is responsible for designing & providing cushion to protect the slurry wall.

Page 14 paragraph f.

indicates peak particle velocity of each component. Please detail what the "Structures onsite" is refering to with a PPV of 2.0 inches per second? We have assumed that this requirement does not apply to our slurry wall per the requirements indicated on page 13 above. We will design the appropriate PPV for the blasing around the slurry wall. Please confirm

The intent is to confirm to the base that the nearby magazine structures and the dam not be damaged. The PPV given for them is 0.5 ips. This was brought up by the owner several times and is not believed to be an issue to either off site location. The blaster should consider any newly constructed structures, including the slurry wall to avoid damage. There are no known existing structures on site.

137 06/11/20 5 05 12 00 1.3 Per paragraph 1.3 the "Work must be fabricated by an AISC Certified Steel Fabricator" Can this requirement be waived or modified for this project. Many of the local, instate, certifed SBE suppliers do not have this certification.

This requirement is eliminating several good qualified companies.

No. This requirement ensures a desired steel quality level and is intended to preclude rework (and costs thereof). AISC's Certified Company Search tool shows 27 steel fabricators within the state of Indiana that maintain BU (building) certification.
