RESPONSE: If the optional work at L24 is not awarded, the extra 7 lock bulkheads will not be provided to the Contractor.

15. What should the contractor do with the extra 7 lock bulkheads if the option work is not awarded? Is there storage on-site at Lock 25 for these bulkheads if not being used at Lock 24? Yes RESPONSE: See response to Question 14 and there is no additional on-site storage at L25 for the bulkheads.

16. 02 41 00 Paragraph 1.5.3 – What equipment to remain shall be protected from the weather?

RESPONSE: See revised specification section per amendment.

17. 02 41 00 Paragraph 3.3 – Will a modification be issued for concrete found to be unsound that was not caused by demolition?

RESPONSE: See revised specification section per amendment.

18. Section 00 08 00 of the specifications includes the following language:

“The following sequence is based on award of base and optional bid items. The Contractor shall install Government Furnished lock bulkheads and pull the Upstream miter gate leaves at Lock 25 before proceeding upriver to Lock 24. Once the Lock 25 Upstream miter gate leaves are laid down and secured on the Government Furnished deck tent barge, the Contractor shall transport the Lock 25 Upstream miter gate leaves and plant to Lock 24. The Contractor shall then install Government Furnished lock bulkheads and pull the Upstream miter gate leaves at Lock 24. Once the Lock 24 Upstream miter gate leaves are laid down and secured on the Government Furnished deck tent barge, the Contractor shall stage the Government furnished deck tent barge downstream of Dam 24 along the riverside of the intermediate lock wall for maintenance repairs to be performed by others.”

The above language requires that the government furnished deck tent barge be staged upstream of the LD 25 bulkheads and the gate leaves must therefore be lifted over the upstream bulkheads and placed on the deck tent barge located upstream of the bulkheads. Conversely, the deck tent barge must be staged downstream of the LD 24 upstream bulkheads to permit it to be moored downstream of LD 24 during the closure period after the LD 24 gate leaves are laid down on the barge. Is our understanding as presented above, correct?

RESPONSE: The statement made above does satisfy the contract requirements.

19. Is it permissible to use Past Performance Questionnaires prepared on NAVFAC/USACE Form PPQ-0 for prior USACE best value procurements? On older projects it is sometimes difficult to contact the person with the most intimate knowledge of our performance and ask that they complete a new form substantially similar to one they have completed previously – sometimes several times.

RESPONSE: The form provided in this solicitation is NAVFAC/USACE Form PPQ-0. Previous versions of this form are permissible provided contract and client information and the adjective ratings are included. A technically acceptable rating shall be evaluated based on client responses to the adjective rating portion of the PPQs as described in section 00100 of the solicitation. PPQs without adjective ratings included are NOT permissible.

20. We have a follow up, related question regarding the below specification:

The specification requires installation of the upstream bulkheads at LD 25 prior to removal of the gate leaves – assuming a large floating crane is used to pick those gate leaves, the crane must therefore be positioned upstream of the bulkheads to be available to move upstream to LD 24. The upstream bulkheads then must be installed at LD 24 prior to removing those upstream gate leaves. Since the

80x300 gate storage barge must be staged downstream of LD 24 once all gate leaves are laid down on the barge, it follows that the floating crane used to pick the gate leaves will therefore work from the downstream side of the LD 24 bulkheads. Furthermore, since the bulkheads at both LD 24 and LD 25 must remain in place until the gate leaves can be re-installed, whatever floating crane is used to pick the gate leaves at the beginning of the lock closures will be trapped between the upstream bulkheads at the two locks. This is true unless there is an alternative sequence available or unless there is a way to operate the dam at LD 25 in a manner that allows use of the auxiliary gate at LD 25 which we understood to be inoperable. Is our understanding of the sequence and conditions correct?

RESPONSE: The Contractors understanding of the sequence and conditions are correct.

21. The Lock 24 & 25 project W912P9-19-R-0033 specification 05 59 13, paragraph 1.4.1, states that the structural steel fabricator for the embedded miter gate anchorage bases needs to be certified as an AISC Certified Plant with Fracture Critical Endorsement. Over the years we have worked with a fabricator that is not AISC certified but has fabricated numerous miter gate anchorage bases for the lock and dams along the Mississippi River in the past.

Based on experience (photos can be shared if requested), and the limited amount of welding required, we would appreciate if the government would consider waiving the AISC Certified Plant requirement for this fabricator.

RESPONSE: The fabricator shall meet AISC certified plant requirements specified in Section 05 59 13.

22. How much do the miter gates weigh at each site?

RESPONSE: See the response to Question 9.

23. Will the miter gates contain debris and if so how much additional weight should be accounted for when sizing the marine plant?

RESPONSE: It is expected that some debris and/or silt will have accumulated on miter gate leaves. The Government does not know the magnitude of additional weight from debris and/or silt.

24. How much do the lock chamber bulkheads weigh?

RESPONSE: See the response to Question 12.

25. Are there walkways available for the top bulkhead at each site and if so what do they weigh?

RESPONSE: The removable sections of walkway sections on the lifting beam are not currently installed on the lifting beam. Offeror shall note that with the number of bulkheads shown on Drawing SC602, the end sections of removable walkway directly over the tapered portion of lifting beam will not be able to be used as shown on reference drawings. The removable end sections each weigh approximately 5,100 lbs and the removable middle sections each weigh 4,000 lbs.

26. How much does the lifting beam weigh?

RESPONSE: See the response to Question 12.

27. Would the COE allow the bulkheads to be installed and removed without the picking beam?

RESPONSE: Pending an approved lifting plan, the bulkheads may be installed or removed without a picking beam. This method will require the use of divers and a 41’ spreader beam.

28. Sheet E-106 – Where is section B1 taken from on this drawing? Is the conduit layout approximately to scale?

RESPONSE: Section B1 is a cross section through the embedded conduit duct bank between Manholes C- 6 and C-4.

29. Sheet E-106, Detail E1 – Will additional depth of concrete demolition be required to access and replace conduits not exposed by sawcut demo? I.e. What will the contractor be required to do if the 13'- 0" long cut at Lock 25 Monolith 206 does not reach the embedded conduits?

RESPONSE: No. The contractor is responsible for replacing conduit sections that are impacted due to concrete removal. Additional concrete removal will only be required if it is necessary to ensure proper installation of new conduit duct bank section.

30. Sheet E-107, Detail E1 states to remove and store the controller, but Sheet SB-107, Detail E1 states to reinstall the controller. Please confirm that it is being reinstalled and reenergized.

RESPONSE: Yes, the controller is to be removed and stored during concrete demo/reconstruction, then reinstalled and re-energized.

31. Sheet E-107, Detail E1 – Are new conductors required for the tow haulage winch controller?

RESPONSE: No, the existing conductors can be reused.

32. We have a question regarding CLIN 0014, Miscellaneous Carne Support at Lock 25. This CLIN requires us to retrieve six roller gate bulkheads from the storage yard an install them in the upstream slots of a roller gate bay as directed after being given a 14-day notice. Our two-part question follows:

a) Please provide reference drawings showing location of the lock 25 storage yard and details of the dam showing the bulkhead slots.

RESPONSE: See revised reference drawings per amendment.

b) Please clarify when this crane support will be required. Will it be required during, before, or after the 105-day closure period?

RESPONSE: See the response to Question 4.

33. Please clarify if the “New Bulkhead Recess Insert” is to only be replaced per drawing SC506. It is unclear if all three sides of the Bulkhead insert are to be replaced or just the RESPONSE: See revised drawing per this amendment. Insert incorrectly marked. Insert is existing.

34. Please clarify if the New Roller Guide (Pg SC514) is only to be replaced on the Monolith (120 and

126) side per detail E4.

RESPONSE: Yes, the new roller guide only applies to Monolith 120 at Lock 24 and Monolith 126 at Lock 25.

35. I know we have asked the weights of the miter gates already, but it has major impacts on our planning how to accomplish the work and as such the estimate. Can you provide these weights as soon as possible please?

RESPONSE: See the response to Question 12.

36. Specification section 00 08 00 paragraph 1.21.A.15 states "The Contractor will be allowed to connect to on-site 480V electrical power receptacles located on the lock walls" How many amps are available on this service?

75. Per Specification 03 20 02 Paragraph 2.1.3.3 - We have spoken to multiple grout and epoxy manufacturers (Dayton/Unitex, Hilti, Five-Star) and none of them believe that the specification for the “Epoxy Grout” for anchoring the dowel holes can be fully met as written.

They agree that the specification appears to be written for an adhesive epoxy, as it references ASTM C881 and ultimate pullout strengths which are characteristics generally listed for adhesive epoxies. However, the specification also calls repeatedly calls out “epoxy grout” for use with dowels, and requires testing the compressive strength of specimens which is not a test performed on adhesive epoxies.

** UNIFORM ALLOWANCE **

If employees are required to wear uniforms in the performance of this contract

(either by the terms of the Government contract by the employer by the state or local law etc.) the cost of furnishing such uniforms and maintaining (by laundering or dry cleaning) such uniforms is an expense that may not be borne by an employee where such cost reduces the hourly rate below that required by the wage determination. The Department of Labor will accept payment in accordance with the following standards as compliance:

The contractor or subcontractor is required to furnish all employees with an adequate number of uniforms without cost or to reimburse employees for the actual cost of the uniforms. In addition where uniform cleaning and maintenance is made the responsibility of the employee all contractors and subcontractors subject to this wage determination shall (in the absence of a bona fide collective bargaining agreement providing for a different amount or the furnishing of contrary affirmative proof as to the actual cost) reimburse all employees for such cleaning and maintenance at a rate of $3.35 per week (or $.67 cents per day). However in those instances where the uniforms furnished are made of ""wash and wear"" materials may be routinely washed and dried with other personal garments and do not require any special treatment such as dry cleaning daily washing or commercial laundering in order to meet the cleanliness or appearance standards set by the terms of the Government contract by the contractor by law or by the nature of the work there is no requirement that employees be reimbursed for uniform maintenance costs.

The duties of employees under job titles listed are those described in the

""Service Contract Act Directory of Occupations"" Fifth Edition (Revision 1) dated September 2015 unless otherwise indicated.

REQUEST FOR AUTHORIZATION OF ADDITIONAL CLASSIFICATION AND WAGE RATE

Standard Form 1444 (SF-1444)

Conformance Process:

The contracting officer shall require that any class of service employee which is not listed herein and which is to be employed under the contract (i.e. the work to be performed is not performed by any classification listed in the wage determination) be classified by the contractor so as to provide a reasonable relationship (i.e. appropriate level of skill comparison) between such unlisted classifications and the classifications listed in the wage determination. Such conformed classes of employees shall be paid the monetary wages and furnished the fringe benefits as are determined (See 29 CFR 4.6(b)(2)(i)). Such conforming procedures shall be initiated by the contractor prior to the performance of contract work by such unlisted class(es) of employees (See 29 CFR 4.6(b)(2)(ii)). The Wage and Hour Division shall make a final determination of conformed classification wage rate and/or fringe benefits which shall be retroactive to the commencement date of the contract (See 29 CFR 4.6(b)(2)(iv)(C)(vi)). When multiple wage determinations are included in a contract a separate SF-1444 should be prepared for each wage determination to which a class(es) is to be conformed.

The process for preparing a conformance request is as follows:

1) When preparing the bid the contractor identifies the need for a conformed occupation(s) and computes a proposed rate(s).

2) After contract award the contractor prepares a written report listing in order the proposed classification title(s) a Federal grade equivalency (FGE) for each proposed classification(s) job description(s) and rationale for proposed wage rate(s) including information regarding the agreement or disagreement of the authorized representative of the employees involved or where there is no authorized representative the employees themselves. This report should be submitted to the contracting officer no later than 30 days after such unlisted class(es) of employees performs any contract work.

3) The contracting officer reviews the proposed action and promptly submits a report of the action together with the agency's recommendations and pertinent information including the position of the contractor and the employees to the Wage and Hour Division U.S. Department of Labor for review (See 29 CFR 4.6(b)(2)(ii)).

4) Within 30 days of receipt the Wage and Hour Division approves modifies or disapproves the action via transmittal to the agency contracting officer or notifies the contracting officer that additional time will be required to process the request.

5) The contracting officer transmits the Wage and Hour decision to the contractor.

6) The contractor informs the affected employees.

Information required by the Regulations must be submitted on SF-1444 or bond paper.

When preparing a conformance request the ""Service Contract Act Directory of

Occupations"" (the Directory) should be used to compare job definitions to ensure that duties requested are not performed by a classification already listed in the wage determination. Remember it is not the job title but the required tasks that determine whether a class is included in an established wage determination.

Conformances may not be used to artificially split combine or subdivide classifications listed in the wage determination."
