Clean Water Construction Grant Program - Resources for Contractors and Subcontractors

<< Back to Clean Water Construction Grant Program main page

A few extra steps are needed to ensure compliance with federal contracting requirements. Below is a list of compliance activities, followed by details and links to websites to aid in these efforts. At the bottom of this page are examples of several required submissions and postings that may easily be downloaded.

Special Note:

Per EPA RAIN-2025-G02 enforcement of the Disadvantaged Business Enterprise (DBE) outreach and reporting requirements is suspended. While US Department of Transportation (DOT) reevaluates the program and issues updated guidance, DOT-OST-2025-0897, state DOTs are not renewing existing or certifying new enterprises. DOEE’s CWC program will not require adherence to DBE requirements until further notice.

Detailed Information on Required Administrative Submissions and Workplace Postings

Build America, Buy America

Contractors and subcontractors must certify that all iron, steel, manufactured products, and construction materials in federally financed infrastructure projects were manufactured in the United States unless a waiver or exemption qualifies. Certification templates and additional resources can be found on the U.S. EPA’s website. Completed BABA certification forms must be readily available at worksites for all iron and steel, construction materials, and manufactured items.

District Workplace Labor Posters

Applicable District of Columbia labor posters are required to be posted at worksites and can be found at the Department of Employment Services’ website.

Employment Opportunity (EEO) Compliance

Employers must post a notice describing federal laws prohibiting job discrimination based on race, color, sex, national origin, religion, age, equal pay, disability or genetic information. An "EEO is the Law" poster can be downloaded or ordered from the EEOC poster webpage. Place this poster on the worksite where notices to applicants and employees are customarily posted.

Project Sign

The project sign informs the public about the nature of the work and the sources and amounts of public funding supporting it. This project sign must be large enough and posted in a place easily viewable to drivers and pedestrians. When designing the sign, contact the project manager for guidance on sign text, agency logos, and funding contributions, and secure final approval before sending the project sign to print. Project signage examples and requirements can be downloaded below.

Stormwater Management Plan Permit

CWC projects are not exempt from District stormwater regulations and projects must secure the necessary permits through DOEE. For additional information, refer to the DOEE Stormwater Management Guidebook.

Invoices

Invoices for work performed must follow the requirements of the contracting agency, but at a minimum, approvable invoices contain the following:

Company letterhead
Date of submittal
Dates of invoice period
Invoice number
Contract number
Project name
Total amount of contract (and change orders as applicable)
Total amount requested
Ledger of amounts requested, amounts received, and balance remaining
Description of work performed
Backup documentation such as payroll register, accounting records, invoices and/or receipts (as applicable)
Signature of authorized company representative or agent
BABA Compliance ***construction only***

Davis-Bacon Wage Rate Determination

The Davis-Bacon wage rate determination is provided in the contract solicitation and determines the minimum amount of money and fringe benefits that must be paid under each labor category. Highlight the labor classifications that will be used in the project and post the cover page and pages with utilized classifications in an area of the construction site easily accessible to project laborers. DOL’s informational Davis Bacon and Related Act (DBRA) signage should be posted in English and Spanish alongside with the wage determination, listing CWC staff as the POC concerning compliance concerns.

When identifying labor categories, if it’s determined that one or more labor roles cannot be matched with an existing labor category, contact CWC staff immediately. The prime contractor is required to work with the Department of Labor (DOL) to have this category added, and CWC staff can provide guidance and DOL contacts. Labor signage requirements can be downloaded below.

For additional information about wage determinations and conformance of work types, refer to DOL’s Davis-Bacon Wage Determination Conformance Request Guide.

Two Week Construction Lookaheads

These reports, submitted every two weeks during active construction, detail the tasks to be performed each day of the upcoming two-week work period, while noting which subcontractors will be on site performing those tasks. An example of this can be downloaded at the bottom of this page.

Certified Payrolls

To comply with requirements of the Davis-Bacon and Related Acts (DBRA), contractors are required to submit certified payrolls within one week after the close of that pay period. DDOT contractors must submit these to DDOT, and all other contractors or grantees must submit them to DOEE CWC staff. The U.S. Department of Labor’s offers a web-based, fillable form as well as a printable form certified payroll templates. An annotated guide to complete the DOL’s certified payroll template is available. Contractors may select an alternative template so long as it meets DOL requirements.
