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)(l)(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

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

WKD Project Number: 20170316.00.CL

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.
Stanly County Davis Bacon Wage Determination
West Stanly WWTP and Sanitary Sewer Improvements SRF 3
WKD Project Number: 20170316.00.CL

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:
Stanly County Davis Bacon Wage Determination

WKD Project Number: 20170316.00.CL

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.
