9. BIDDING AND CONSTRUCTION RFI QUESTIONS AND RESPONSES:

A. We did not see a RFI due date. Has a date been established for RFIs? Due 14 Jul 2020.

Response: RFI’s were due 17 July 2020.

B. Are As builts available that would show the thickness of the concrete and asphalt that is scheduled to be removed?

Response: Assume the concrete and asphalt thickness at 6”. Assume the concrete is reinforced.

C. The POP is noted as 500 days. 4.D.1.c. in the SOW has all work completed prior to

Friday, 13 August, 2021. Does this mean all work will stop during the football season and be able to resume after football season to allow the total of 500 day?

Please clarify.

Response: See revised SOW sections 4.D1, D2 and 8. All work will stop during the football season and be able to resume after football season to allow the total of 500 day POP. The stadium shall be safe, complete and usable during football season.

The contractor’s means and methods will determine the final POP.

D. Are the drawings reflective of the utility work performed with the Elevator project at the south end of the stadium? Please confirm the drawings are consistent with the new work performed.

Response: The utility project XQPZ170104 design was completed before the elevator project XQPZ120107as-builts were available. The design for project XQPZ170104 shows many existing utilities that must be avoided. The contractor’s will use their own means and methods to avoid existing utilities. See SOW attachment A-1. This attachment shows COMM and electrical lines placed as part of project XQPZ120107. This attachment shows additional utilities that must be avoided.

E. Will additional saw joints in the concrete be acceptable as long as they do not create small trenches and create an aesthetically appealing appearance? To take concrete out at the current joints would require removal of handrails and step or edge nosings.

Response: The intent is not to have narrow saw cut splices in the concrete for the new utility trenches. The intent is to use the existing control joints as the boundary for new concrete placement. Additional saw cut joints in the concrete shall be acceptable as long as they do not create narrow trench patches in the concrete.

The intent is to leave the handrails and step edges intact.

F. Reference Sheet Note 4 on sheets CD101 to CD106 Abandon Existing Utility In place. And Sheet Note 2 on sheets CD101 to CD106 Remove and Demolish Existing Gas Piping, Valves and Fittings In some instances, utilities marked with Sheet Note 2 (Remove) can be left in place without creating a conflict with or hampering the installation of the new utility line. This may save unnecessary removal of concrete and may make the project work more efficient and economical.

In these instances, is it acceptable to abandon the utility in place?

Response: Utility space available inside the stadium is limited, the location of the existing utility may be the only space available, in some areas. The intent is to remove the existing utility where marked with note 2. Water lines marked with note 4 are believed to contain asbestos are to be left in place.

G. Concrete Removal / Replacement Scope - Reference Sheets CD101 to CD106

If new utility installation work can be accomplished without removal of all concrete shown to be removed on Sheets CD-101 to CD-106 is it acceptable to leave the existing concrete in place in its current condition?

Response: The intent is not to have narrow saw cut splices in the concrete for the new utility trenches. The intent is to use the existing control joints as the boundary for new concrete placement. Additional saw cut joints in the concrete shall be

H. Epoxy - On the North End of the Lower Level the existing concrete has been treated with epoxy. Is it necessary to reapply the epoxy after the concrete has been replaced? If it is necessary, please indicate if there’s any particular product or installation method to be utilized.

Response: See attachment D, the Neogard waterproofing manual. The winning bidder will coordinate the existing coating warranty with CE and the manufacturer.

I. Ticket Booth - Sheet CD101 indicates that the existing Ticket Booth shall be temporarily relocated during demolition and construction of new water and gas service. What if any utilities will need to be disconnected and reconnected to facilitate this relocation?

Response: The Ticket Booth has electricity, this will have to be disabled and reconnected.

J. Saw Cutting at Curb Lower and Middle Level at Pre-Cast - Reference Sheets

CD101 to CD106. It was discussed during the site visit that at the Lower and Middle Levels the concrete will need to be removed full width due to the existing joint pattern. The existing pre-cast wall sits on a curb that abuts the concrete. To facilitate the work and avoid interfering with or undermining the walls is it acceptable to hold the saw-cut/removal line off the existing curb by a foot or two if the result is uniform in appearance?

Response: The intent is not to have narrow saw cut splices in the concrete for the new utility trenches. The intent is to use the existing control joints as the boundary for new concrete placement. Additional saw cut joints in the concrete shall be

K. Scoreboard Location – Reference Sheet CD105 and CU105 indicate that the scoreboard is located roughly 60’ from the existing retaining wall at the planter. In actuality, the scoreboard is located roughly 30’ from the retaining wall. And the existing electrical manhole is shown on the drawing to be roughly 40’ from the scoreboard. However, the manhole is actually roughly 10’ from the scoreboard.

The plans show the new utilities running in the space between this existing electrical manhole and the scoreboard. Giving the dimensional errors mentioned above, there is not enough space between the existing electrical manhole and the scoreboard to install the new utilities as shown on the plans.

Please advise if it would instead be acceptable to route the new utilities around the other side of the scoreboard. Or if not, please identify the desired alternate path.

Response: It shall be acceptable to route the new utilities around the other side of the scoreboard. The utility project XQPZ170104 design was completed before the elevator project XQPZ120107as-builts were available. The design for project XQPZ170104 shows many existing utilities that must be avoided. The contractor’s will use their own means and methods to avoid existing utilities. See SOW attachment A-1. This attachment shows COMM and electrical lines placed as part of project XQPZ120107. This attachment shows additional utilities that must be

L. Existing Electrical Service Location – Reference Sheet CD105 and CU105 – The New Elevator Project (Shown on the plans as Future Project No. XQPZ 12-0107) has been completed. The electrical service feeding those new elevator towers is not shown on the project drawings as the work was completed after the date of this project’s drawings. The new electrical service for those elevator towers is in direct conflict with the alignment of the new proposed Gas and Water Services, as is the newly installed landscaping. Does the Government desire for the new Gas and Water Service to Be shifted south of the Existing Electrical Service, further into the existing field? Please see attached As-Built Drawing from the Elevator Project showing the work in conflict.

Response: The utility project XQPZ170104 design was completed before the elevator project XQPZ120107as-builts were available. The design for project XQPZ170104 shows many existing utilities that must be avoided. The contractor’s will use their own means and methods to avoid existing utilities. See SOW attachment A-1. This attachment shows COMM and electrical lines placed as part of project XQPZ120107. This attachment shows additional utilities that must be

M. Sewer Manhole Depth – Reference Sheet CU109. The table below is pasted from

CU109 and refers to the existing Manhole Located at Gate 1, which is a point of connection for the sewer on the East Side of the Stadium. This information indicates that the manhole is roughly 37’ deep. The asterisks refer to Note five pasted below which indicate the depth of the manhole is likely inaccurate, but it hasn’t been verified. It seems unlikely that the manhole is actually 37’ deep. However, it’s important for pricing this work to know for sure. Can the Government please verify the depth of this manhole?

Response: It appears that the main inlet is from the NW 12” clay. The outlet is unclear. It appears that the rim actually increase in elevation from the east, whereas the sewer pipe must loose elevation as the sewer flows. The actual depth will have to be field verified. Assume 37’ depth for bidding purposes.

N. Concrete Removal at Press Box - Reference Sheet CD103 Refer to Sketch

In the area indicated, panels are full width. CD103 as shown above indicates smaller areas of removal/replacement. The work is limited to a small area of the overall panel dimensions. Is it acceptable to move the Water and Gas closer together and add a joint nearer to the wall or otherwise break these panels into smaller pieces so long as the result is uniform in appearance?

Response: Yes, the lines may be placed in one trench, as long as the 10’ clearance between water and sewer lines can be maintained. CE suggests opening the trench to the west first to verify that clearance is available between foundations and other utilities.

O. Would the government consider a shorter bid acceptance period? Between tariffs, COVID-19, and various other issues, there is a lot of uncertainty and fluctuation in the cost of materials. It would be more advantageous to the government (in terms of lower pricing) to shorten the bid acceptance from 12/31/20 down to something like 30 or 60 days. Near the end of the 30 or 60 days, the government could “open” the solicitation up for further negotiation with the firms who originally submitted a valid bid proposal (or some similar approach). Additionally, as this is a HUBZone set-aside, there are multiple factors that could impact the status of HUBZone certifications between now at 12/31/20.

Response: Due to uncertainty of imminent funding capabilities, the bid acceptance date shall remain 31 Dec 2020.

P. Are there any other utilities in or around the Stadium in the areas of work that may be impacted, such as Steam Piping?

Response: All the known utilities are shown on attachment C and on the drawings.

No steam piping is expected.

Q. Is it the intent to awarded all contract line item or just a portion.

If only a portion is awarded the CIPP installation is stopped in the middle of a run and this is very difficult to do. It would need to be taken to the next manhole.

Do you want bids to the broken down that way?

Response: The intent is to award all Contract Line Items (CLINs). The intent is to cast in place from manhole to manhole. The line of separation shown in CLIN 002 is where the sewer line changes facility number. Separate bid CLINs are required per Government regulations.

R. What are the anticipated Sewer flows to be dealt with during Lining operations and

Gravity sewer tie ins?

Response: Figure 40% of max flow based on diameter for bidding purposes.

S. Is imported pipe bedding to be required for the Water, Gas and Sewer Pipe? If so what type of bedding is required?

Response: Importing of bedding soil is expected if the natural soil cannot meet the requirements shown in the specifications

T. Under Factor 2 - Technical/Experience it states that the "project was completed within the past five (5) years from the issuance date of the solicitation. Would allow for projects that are 90% complete prior to issuance, especially those that are design-build and require substantial time for design?

Response: No. Projects must be completed or have a documented Beneficiary Occupancy Determination (BOD) letter or inspection by the issuance of the solicitation date.

U. Under Factor 2 - Technical/Experience, are we allowed to use a project from our teaming partner (a non Joint Venture partner)?

Response: The offeror shall be the prime contractor, subcontractor or joint venture on both submitted projects on the Attachment 7, Technical Evaluation Form.

V. Please provide drawings that show the concrete panel layout to be able to identify the concrete quantities that need to come out and be replaced.

Response: The panel layout depends on the contractor’s means and methods. The contractor will field verify the concrete quantities based on each contractor’s means and methods.

W. Please provide the thickness of the existing concrete.

Response: Assume the concrete thickness at 6”. Assume the concrete is reinforced.

X. Please provide a specification for the concrete coating that is located on the north end near the tunnel.

Substrate & Project Conditions

Concrete

1. Verify that the work done under other sections meets the following requirements:

• The concrete deck surface is free of ridges and sharp projections. If metal forms or decks are used, they should be ventilated to permit adequate drying of concrete on exterior exposed deck.

• The concrete was cured for a minimum of 28 days. Minimum compressive strength: 3,000 psi for pedestrian traffic, 4,000 psi for vehicular traffic. Water-cured treatment of concrete is preferred.

The use of concrete curing agents, if any, shall be of the sodium silicate base only; others require written approval by NEOGARD®.

• The concrete was finished by a power or hand steel trowel followed by soft hair broom to obtain light texture or “sidewalk” finish similar to photo below.

• Damaged areas of the concrete deck are restored to match adjacent areas. Use 100% solids epoxy and sand for filling and leveling. See Concrete Patching section in Surface Preparation section of this manual.

Plywood

1. Verify that the plywood deck work done under other sections meets the following requirements:

• Plywood is of exterior grade quality and minimum B-C grade with B side to receive coating.

Plywood shall be at least 5/8” thick. Tongue and groove plywood is preferred.

• Joist spacing beneath plywood deck has a maximum spacing of 16” O.C.

• It is recommended that a bead of 70991 or 70995 polyurethane sealant be laid on the joist with the plywood decking installed immediately on top of the wet sealant.

• Plywood imperfections are filled with 70991 or 70995 polyurethane sealant.

• Spiral or coated nails are used and are driven flush with the surface of plywood. Nails shall not be countersunk.

• A maximum of 1/16” space between sheets of plywood is maintained while deck is being placed.

• Plywood decking is to be covered as soon as possible after installation.

Field Sample

1. Install a field sample of at least 100 square feet at the project or pre-selected area as agreed to by owner’s representative, applicator and manufacturer.

Page 6 Application Manual - Waterproofing Systems

2. Apply material in accordance with written application instructions.

3. Field sample will be the standard for judging color and texture on remainder of project.

4. Maintain field sample during construction for workmanship comparison.

5. Do not alter, move, or…
