Overtime Utilities

Program History and Overview

The General Services Administration’s (GSA) overtime services program provides our tenants with the assurance that they have the required support and services essential to carrying out their mission requirements.  The program operates in an environment that authorizes the tenant to provide GSA with the necessary reimbursable funding to cover the costs to deliver to our tenants services that exceed GSA's 10 hour daily standard for building operations.  The Authority, for OU services and collections are in the Federal Property and Administrative Services Act of 1949, as amended, and as revised, restated and re-codified without substantive change by P.L. 107-217 [PDF - 3.52 MB] (Title, 40 U.S.C., Subtitle I).

Our goal is to ensure that these services and practices meet or exceed those that are furnished in the private sector.  We are committed to maintaining a collaborative process between our tenants and GSA to ensure that overtime utilities are managed to meet your requirements and expectations.

GSA has established a National Overtime Utilities team to guide the program and estimating process.  Part of the team’s tasking included developing tools and enhancements to standardize and make the estimating process easier.  These included  an Overtime Utilities Estimating Tool (OUET) implemented in RETA to prepare and track overtime estimates.  

To better serve you, we developed this site to help explain GSA’s overtime utility services program and tools.  It should make it easier and more efficient for you to navigate through the complexity and hurdles of understanding how your overtime services are calculated.
