Contracting with DEA
Steps for ordering services from DEA are outlined below. You may also review GSA’s Federal Supply Service Website at http://www.gsa.gov/portal/category/26760, which includes a section on ordering information.
- Develop a statement of work for one or more of the services provided by DEA under this contract. The statement should include, at a minimum, the work to be performed, the location of the work, the period of performance, a schedule of deliverables, applicable standards, and any special requirements needed to complete the work (such as security clearances, travel, special knowledge, specific equipment, models to be used for analysis, etc.).
- Develop a government cost estimate.
- Review available information from at least three contractors as allowed by Federal Acquisition Regulations (FAR 8.404), including price lists and qualifications information. This information is available through the GSA Advantage! online shopping service (www.gsaadvantage.gov). This review may be sufficient to meet the competition requirements for acquiring services (check with your local contracting staff). If further competition is desired, the scope can be forwarded to other consultants as described in step 4.
- Issue a request for cost quote to at least three of the consulting firms holding GSA Environmental Services contracts with the proper qualifications (a list of these firms can be reviewed at GSA eLibrary). This request should include the proposed scope (statement) of work, evaluation criteria, and an indication of whether you are seeking a firm-fixed price or labor hour level-of-effort cost quote for the services.
- Determine which contractor represents the best value. According to FAR, cost is to be considered, but you may also consider other relevant factors, such as special qualifications and past performance. Document your rationale for identifying the best value.
- Provide to your contracting office the material developed in the previous steps.
- Request final cost from “best value” firm. Your contracting office can then request the best value firm to submit a final firm-fixed price or labor hour level-of-effort cost quote for the requested services.
- Issue a task order. Following a negotiation of cost and services, if necessary, the contracting office can issue a task order directly with the contractor.
