Note: Under Executive Order (EO) 13658, an hourly minimum wage of $10.80 for calendar year 2020 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, 2015.

If this contract is covered by the EO, the contractor must pay all workers in any classification listed on this wage determination at least $10.80 per hour (or the applicable wage rate listed on this wage determination, if it is higher) for all hours spent performing on the contract in calendar year 2020. If this contract is covered by the EO and a classification considered necessary for performance of work on the contract does not appear on this wage determination, the contractor must pay workers in that classification at least the wage rate determined through the conformance process set forth in 29 CFR 5.5(a)(1)(ii) (or the EO minimum wage rate, if it is higher than the conformed wage rate). The EO minimum wage rate will be adjusted annually. Please note that this EO applies to the above-mentioned types of contracts entered into by the federal government that are subject to the Davis-Bacon Act itself, but it does not apply to contracts subject only to the Davis-Bacon Related Acts, including those set forth at 29 CFR 5.1(a)(2)-(60). Additional information on contractor requirements and worker protections under the EO is available at www.dol.gov/whd/govcontracts.

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)).

Section 00 73 46 - Page 3

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

Section 00 73 46 - Page 4

TO ACCOMPANY AMENDMENT 0006 OF SOLICITATION NO. W912HY20R0001

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

Section 00 73 46 - Page 5

TO ACCOMPANY AMENDMENT 0006 OF SOLICITATION NO. W912HY20R0001

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.

AMENDMENT NO. 0006

PART 1 GENERAL

1.1 SUMMARY

The work in this Section consists of furnishing plant, labor, materials, and equipment and performing the operations necessary for the removal of materials to the required dimensions shown, satisfactory disposal thereof, and other operations incidental thereto.

1.2 DEFINITIONS

(a) Plant: Hydraulic pipeline (i.e. cutterhead, plain suction, sidecaster) dredges; Mechanical Type (Bucket) or clamshell dredges;

Hopper dredges, etc.

(b) Dredging Equipment: Machinery, structures, equipment, piping, vessels, dredges, dump scows, tugs, boats, barges, and systems purchased, owned, rented or leased by Contractor for use in accomplishing the Work, but not intended for incorporation into the Dredging Project as a permanent structure.

(c) Dredging: The underwater excavation of soils for channel and/or harbor deepening. Removal of loose or hard, compacted materials, either for maintenance or new work projects.

1.3 MEASUREMENT AND PAYMENT

Measurement and payment for DREDGING will be paid for in accordance with provisions of the SECTION 01 22 00.10 MEASUREMENT AND PAYMENT.

1.4 WORK COVERED BY CONTRACT PRICE

Base bids on the quantity of dredging indicated. If the total quantity of dredging varies from that specified as the basis for bidding, the Contract price will be adjusted in accordance with the CONTRACT CLAUSE entitled CHANGES. The dredging conditions specified and indicated describe conditions which are known. However, the Contractor is responsible for other conditions encountered which are not unusual when compared to the conditions recognized in the dredging business as usual in dredging activities such as those required under this Contract. The Contract price for dredging will include the cost of removal and placement of the material as specified in the Paragraphs: CHARACTER OF MATERIAL and PLACEMENT OF EXCAVATED MATERIAL. The Contract price for dredging will include the costs for maintenance of dikes and ditches necessary to confine the material within the areas shown.

1.4.1 Existing Conditions

The drawings already prepared as specified in the CONTRACT CLAUSES Paragraph entitled CONTRACT DRAWINGS AND SPECIFICATIONS represent

SECTION 35 20 23.16 45 Page 3 conditions existing as of the date of their preparation using average existing conditions. However, to reflect anticipated shoaling or scour occurring between the dates of preparation of the drawings and the dates of the "Before-dredging" surveys sections, the estimated dredging quantities stated in the Bid Schedule have been adjusted accordingly. The depths and elevations shown will be verified and corrected by fathometer soundings taken by the Government before dredging. The Government will normally use a frequency of 200 kHz to conduct hydrographic surveys. If the surveys indicate the presence of fluff in the channel, a frequency of 40 kHz will be used. Determination of quantities removed and the deductions made from them to determine quantities by in-place measurement to be paid for in the area specified, after having once been made will not be reopened, except on evidence of collusion, fraud, or obvious error.

1.8 CHARACTER OF MATERIAL TO BE REMOVED

All MAINTENANCE material can be dredged and disposed of as per NEW WORK material. Explorations, including core borings, to determine the character of materials to be removed have been obtained by the Government and the results are indicated. The borings data is for information purposes only.

Borings were drilled during the 1960s, 1970s, 2000, and in 2018. Portions of the boring logs have been previously dredged.

Bidders are expected to examine the worksite and the records of previous dredging activities, which are available upon request from the Galveston District Southern Area Resident Office and after investigation, decide for themselves the character of materials.

1.8.1 Debris Within the Dredging Limits

Debris including but not limited to, metal bands, pallets, pieces of broken cable, rope, stumps, and broken piles may be encountered. The Government has no knowledge of existing wrecks, wreckage, or other material of that size or character as to require the use of explosives or special or additional plant for its economical removal. Debris removed from the dredged area is to be removed from the water. Disposal is to be the responsibility of the Contractor and disposal is to be outside the limits of Government property. If the actual conditions differ from those stated or shown, an adjustment in Contract price or time of completion, or both, will be made in accordance with the CONTRACT CLAUSE entitled

DIFFERING SITE CONDITIONS.
