SECTION SF 30 BLOCK 14 CONTINUATION PAGE

The following items are applicable to this modification:

AMENDMENT PARTICULARS

D. CHANGES TO SPECIFICATIONS are as follows. The Revised Section pages are attached hereto.

1. Section 35 31 25 & Sheet C-103 – revised as following:

The incorrect version of the grouting specifications was mistakenly included in the solicitation. This also led to an incorrect note being placed on one of the details in the drawings. The contract does not require a mockup of the grouting methods, grout mix D is not required by the contract, and the specifications do not dictate the type of grout barriers to be used.

E. USACE RESPONSE TO CONTRACTOR’S QUESTIONS:

QUESTION 1. Adam Borelli indicated at the pre-bid that the question and answer period would be extended. What is the new deadline? Will this result in the bid date be extended and if so to what date?

A. The USACE cannot impose a deadline, however, this is a critical project and we are highly encouraging all questions be submitted by 19 September 2017 to avoid delaying the bid opening.

QUESTION 2. An addendum was mentioned yesterday the meeting yesterday, when will that addendum be issued?

A. This document serves as the addendum, which is considered an “Amendment” in terms of our procurement regulations.

QUESTION 3. Is there any underwater survey data available for the work area in question?

A. REFER to Drawing Sheet C-102.

QUESTION 4. What is the list of USACE approved labs? The URL is missing from section 01 45 00.00 paragraph 3.7.2.

A. The URL link is: https://media.defense.gov/2017/Sep/13/2001808436/-1/-

1/1/170912_CEERD-GMC_VALIDATEDLABS%20.PDF

QUESTION 5. Which bid item should the outward crushed stone containment blanket be applied to?

A. The requirement for an “outward crushed stone containment blanket” has been deleted from the project specifications.

W912P617B0010

QUESTION 6. Which bid should the compatibility test program mock-up section be applied to?

A. The requirement for a “compatibility test program mock-up section” has been deleted from the project specifications.

QUESTION 7. The list of alignment points on sheet C-101 indicate a 500’ base bid, and two 250’ options, but the bid schedule shows three options. Please provide a corrected sheet C-101, or the starting and ending station of each option and base bid.

A. No Options Areas are shown on the drawings. The bid items are based on quantities and not length of structure.

QUESTION 8. What is the anticipated NTP?

A. The USACE anticipates an award on 30 September 2017. The successful bidder will have 10 days from contract award to submit legally sufficient bonds and insurance. Once the bonds and insurance have been approved by our legal department, the Notice to Proceed (NTP) will be issued AND subsequently acknowledged by the contractor. In consideration of this timeline, we expect the NTP to be issued on or about 30 October 2017.

Note: Executive Order (EO) 13706, Establishing Paid Sick Leave for Federal Contractors applies to all contracts subject to the Davis-Bacon Act for which the contract is awarded (and any solicitation was issued) on or after January 1, 2017. If this contract is covered by the EO, the contractor must provide employees with 1 hour of paid sick leave for every 30 hours they work, up to 56 hours of paid sick leave each year.

Employees must be permitted to use paid sick leave for their own illness, injury or other health-related needs, including preventive care; to assist a family member (or person who is like family to the employee) who is ill, injured, or has other health-related needs, including preventive care; or for reasons resulting from, or to assist a family member (or person who is like family to the employee) who is a victim of, domestic violence, sexual assault, or stalking. Additional information on contractor requirements and worker protections under the EO is available at www.dol.gov/whd/govcontracts.

Unlisted classifications needed for work not included within the scope of the classifications listed may be added after award only as provided in the labor standards contract clauses (29CFR 5.5 (a) (1) (ii)).

The body of each wage determination lists the classification and wage rates that have been found to be prevailing for the cited type(s) of construction in the area covered by the wage determination. The classifications are listed in alphabetical order of "identifiers" that indicate whether the particular rate is a union rate (current union negotiated rate for local), a survey rate (weighted average rate) or a union average rate (weighted union average rate).

Union Rate Identifiers

A four letter classification abbreviation identifier enclosed in dotted lines beginning with characters other than "SU" or "UAVG" denotes that the union classification and rate were prevailing for that classification in the survey. Example:

PLUM0198-005 07/01/2014. PLUM is an abbreviation identifier of the union which prevailed in the survey for this classification, which in this example would be Plumbers. 0198 indicates the local union number or district council number where applicable, i.e., Plumbers Local 0198. The next number, 005 in the example, is an internal number used in processing the wage determination. 07/01/2014 is the effective date of the most current negotiated rate, which in this example is July 1, 2014.

Union prevailing wage rates are updated to reflect all rate changes in the collective bargaining agreement (CBA) governing this classification and rate.

Survey Rate Identifiers

Classifications listed under the "SU" identifier indicate that no one rate prevailed for this classification in the survey and the published rate is derived by computing a weighted average rate based on all the rates reported in the survey for that classification. As this weighted average rate includes all rates reported in the survey, it may include both union and non-union rates. Example: SULA2012-007 5/13/2014. SU indicates the rates are survey rates based on a weighted average calculation of rates and are not majority rates. LA indicates the State of Louisiana. 2012 is the year of survey on which these classifications and rates are based. The next number, 007 in the example, is an internal number used in producing the wage determination. 5/13/2014 indicates the survey completion date for the classifications and rates under that identifier.

Survey wage rates are not updated and remain in effect until a new survey is conducted.

Union Average Rate Identifiers

Classification(s) listed under the UAVG identifier indicate that no single majority rate prevailed for those classifications; however, 100% of the data reported for the classifications was union data. EXAMPLE: UAVG-OH-0010 08/29/2014. UAVG indicates that the rate is a weighted union average rate. OH indicates the state. The next number, 0010 in the example, is an internal number used in producing the wage determination. 08/29/2014 indicates the survey completion date for the classifications and rates under that identifier.

A UAVG rate will be updated once a year, usually in January of each year, to reflect a weighted average of the current negotiated/CBA rate of the union locals from which the rate is based.

WAGE DETERMINATION APPEALS PROCESS

1.) Has there been an initial decision in the matter? This can be:

* an existing published wage determination

* a survey underlying a wage determination

* a Wage and Hour Division letter setting forth a position on a wage determination matter

* a conformance (additional classification and rate) ruling

On survey related matters, initial contact, including requests for summaries of surveys, should be with the Wage and Hour Regional Office for the area in which the survey was conducted because those Regional Offices have responsibility for the Davis-Bacon survey program. If the response from this initial contact is not satisfactory, then the process described in 2.)

and 3.) should be followed.

With regard to any other matter not yet ripe for the formal process described here, initial contact should be with the Branch of Construction Wage Determinations. Write to:

Branch of Construction Wage Determinations Wage and Hour Division U.S. Department of Labor 200 Constitution Avenue, N.W.

Washington, DC 20210

2.) If the answer to the question in 1.) is yes, then an interested party (those affected by the action) can request review and reconsideration from the Wage and Hour Administrator (See 29 CFR Part 1.8 and 29 CFR Part 7). Write to:

Wage and Hour Administrator U.S. Department of Labor 200 Constitution Avenue, N.W.

Washington, DC 20210

The request should be accompanied by a full statement of the interested party's position and by any information (wage payment data, project description, area practice material, etc.) that the requestor considers relevant to the issue.

3.) If the decision of the Administrator is not favorable, an interested party may appeal directly to the Administrative Review Board (formerly the Wage Appeals Board). Write to:

Administrative Review Board U.S. Department of Labor 200 Constitution Avenue, N.W.

Washington, DC 20210

4.) All decisions by the Administrative Review Board are final.

1.2 SYSTEM DESCRIPTION

This section of the specifications covers construction of conducting pre-grouting compatibility program on land; installing grout containment barriers on both sides of the breakwater, drilling through concrete

SECTION 35 31 25 Page 3 breakwater cap, using either diamond rotary or percussion drilling equipment, making grout connections; furnishing, handling, transporting, storing, mixing and injecting the grouting materials; backfilling holes;

patching and backfilling the finished grout holes; clean up of the areas upon completion of the work and all other such operations as are incidental to the drilling and grouting. The work consists of constructing a grout curtain, the approximate locations, limits, and details which are indicated in the drawings using both quick-setting sodium silicate grouts and low-mobility consolidation grouts.

Drilling, grouting shall follow the sequence of work presented in the Contractor's Drilling and Grouting Work Plan and approved by the Contracting Officer Representative (COR). Adherence to the schedule and sequence directed by the COR will not be seen as cause for time extension or claims for additional costs beyond those specified herein.

1.3 DEFINITIONS

1.3.1 General

The drilling and grouting shall consist of a multi-line grout curtain.

The inner and outer single lines of the grout curtain shall be grouted using a fast-setting portland cement-sodium-silicate grout for containment of grout from the inner rows of grout holes. The three lines of the interior grout curtain shall be grouted using low/non-shrink balanced stabilized sanded portland cement grout with anti-washout characteristics. The drilling and grouting shall be performed on series of boreholes within sections, using the methods as described herein.

1.3.1.1 Series

A series of grout holes refers to a group of boreholes grouted simultaneously at one station aligned perpendicular to the breakwater structure within the inner three rows of the grout curtain.

1.3.1.2 Section

A section is a division along the grout curtain, not less than 50 feet up and down station from a hole being drilled or grouted within which grouting of successive series of holes shall be simultaneously grouted.

Insofar as practicable, the grout curtain shall be subdivided into sections in a manner to facilitate the Contractor's operations; however drilling within one section adjacent to a section that has yet to be grouted shall not be done except as directed by the COR.

1.3.1.3 Row

A row is defined as the line of holes parallel to the structure. There are 5 rows designed as shown on the Drawings:

Row A - the row of borings along the lake side of the structure;

Row B - the row of interior holes toward the lakeside;

Roc C - the Centerline row of interior holes;

Row D - the harbor side row of interior holes Row E - the row of holes nearest the harbor side of the structure.

SECTION 35 31 25 Page 4

1.3.1.4 Cycle

A cycle under these Specifications is defined as a period of continuous grouting of a hole from start to shut off of grout flow. Holes may be grouted for more than one cycle, following sufficient elapsed time between cycles for the grout to set, in cases where grouting was suspended prior to grout communicating with adjacent holes, or due to the appearance of grout outside of containment, or when interruption is directed by the COR.

1.3.1.5 Intermittent Grouting

Intermittent grouting under these Specifications is defined as grouting of more than one cycle applied to the same grout hole, each cycle separated by sufficient time for the grout to reach initial set.

1.3.1.6 Split Spacing

Split spacing is the procedure of locating an additional grout hole midway between two previously drilled and grouted holes.

1.3.1.7 Closure

Closure is defined as the acceptable level of void-filling of a section achieved by grouting. For this Contract, the closure criteria are:

1. Observed complete filling of voids in the stone fill within the timber crib to the designed extent, determined by the presence of grout filling or being clearly visible in adjacent holes; or

2. Cessation of grouting directed by the COR.

1.3.1.8 Refusal

Refusal is defined for this Contract as the condition where a hole accepts no grout under the pressure exerted by the grout pump.

1.3.1.9 Communication

Communication is the passage of water or grout from one hole to another or to any opening or exposed surface during the course of drilling and/or grouting.

1.3.1.10 Balanced Stable Grout

A grout mixture that exhibits minimal (less than 5 percent) bleed and retains the desired rheologic properties , viscosity, and cohesion throughout the pumping and placement processes regardless of pumping rate, turbulence or agitation.

1.6.2 Field Measurements

The Contractor shall produce a preliminary grout hole layout for the review and approval of the COR. The final drill hole locations will be as approved by the COR prior to the start of work. The locations of drill holes shall be surveyed by the Contractor to the nearest 0.1 ft on the NAD 83 coordinate system and elevations surveyed using the Chicago City Datum.

1.7 SEQUENCING AND SCHEDULING OF DRILLING AND GROUTING

1.7.1 General

The order in which the work is to be accomplished shall be as outlined in the Compatibility Test Program Work Plan and Drilling and Grouting Work Plans and as approved by the COR. The general requirements that shall apply are as follows:

a. Conduct an on-land Compatibility Test Program using the actual grouting equipment to develop the mix designs for the containment grout and low mobility grout. Base line rheologic and physical properties grout mixes shall be established.

b. Install the harbor side and lake side grout containment barriers for the first 100-feet to be grouted.

c. The Contractor shall verify the correct and approved location, orientation and alignment of the grout holes before drilling and installing any casings, should casings be deemed necessary. Casing may be used at the convenience of the Contractor, but no separate payment will be made for casing. Establish and layout sections of the grout curtain to be drilled and grouted in sequence and mark grout

SECTION 35 31 25 Page 8 holes and sections on the concrete breakwater cap accordingly with paint.

d. For each section of the grout curtain, drilling and grouting of the lakeward row (Row A) shall be completed before proceeding with drilling and grouting of the harborside holes (Row E) and the interior rows of the grout curtain. Monitor adjacent holes and the water lakeward and harborside of the breakwater during grouting for the presence of grout communicating. If grout appears beyond containment barrier, report this observation to the COR immediately, cease grouting and adjust grout flows, containment procedures, and/or mix to prevent recurrence before commencing grouting. Only after direction by the COR may the Contractor continue grouting a hole that has resulted in communication to the lake water. Grout each hole until:

1. Grout is detected in adjacent holes;

2. 8 cubic yards of grout has been injected, or;

3. The hole refuses to accept grout;

4. Directed by the COR to stop.

In the case of both the lakeward and harborside rows of grout holes, grouting shall be done using split-spacing on holes 8-feet apart, such that every other hole is grouted first, and then the intermediate holes are re-drilled (if necessary) and grouted, resulting in an array of holes on 4-foot spacing.

e. After both the lakeward and harborside rows of grout holes have been completely grouted, drill…
