The types of services offered under the Professional Engineering Services (PES) schedule are listed below according to their Special Item Number (SIN). Also included are examples of how the SIN may be used to complete an engineering project. Please Note: Many different tasks can be performed under each Special Item Number.  The sample scenarios below only scratch the surface of possibilities under this schedule and are only provided as illustrations to describe each SIN.

Agencies can obtain a wide range of engineering services under this schedule.  To view the list of included engineering disciplines, sub-disciplines and an additional list of services not included under the PES schedule, please go to the Professional Engineering Disciplines section.

871-1 STRATEGIC PLANNING FOR TECHNOLOGY PROGRAMS/ACTIVITIES

Services available under this SIN involve the definition and interpretation of high-level organizational engineering performance requirements such as projects, systems, missions, etc., and the objectives and approaches to their achievement.

871-2 CONCEPT DEVELOPMENT AND REQUIREMENTS ANALYSIS Services available under this SIN involve abstract or concept studies and analysis, requirements definition, preliminary planning, the evaluation of alternative technical approaches and associated costs for the development or enhancement of high level general performance specifications of a system, project, mission or activity.

871-3 SYSTEM DESIGN, ENGINEERING AND INTEGRATION

Services available under this SIN involve the translation of a system (or subsystem, program, project, activity) concept into a preliminary and detailed design (engineering plans and specifications), performing risk identification/analysis/mitigation, trace ability, and then integrating the various components to produce a working prototype or model of the system.

871-4 TEST AND EVALUATION

Services available under this SIN involve the application of various techniques demonstrating that a prototype system (subsystem, program, project or activity) performs in accordance with the objectives outlined in the original design.

871-5 INTEGRATED LOGISTICS SUPPORT

Services available under this SIN involves the analysis, planning and detailed design of all engineering specific logistics support including material goods, personnel, and operational maintenance and repair of systems throughout their life cycles.

871-6 ACQUISITION AND LIFE CYCLE MANAGEMENT

Services available under this SIN involve all of the planning, budgetary, contract and systems/program management execution functions required to procure and/or produce, render operational and provide life cycle support (maintenance, repair, supplies, engineering specific logistics) to technology-based systems, activities, subsystems, projects, etc.
