The selection committee should define the type of professional services needed. Common types of professional services required in the course of a complex project include:
1. Preliminary design and development

- Field investigations — includes topographical surveys, soil surveys and environmental assessments
- Preliminary design — states assumptions, shows proposed layouts and outlines design concepts
2. Final design phase — This phase happens after approval of the preliminary design by regulatory agencies and the project owner.

It also may include meetings with funding agencies.
3. Bidding/negotiating phase — The engineer helps the owner advertise the project, obtain and evaluate bids, and negotiate contracts for construction services.

- Assistance in drafting and/or reviewing a construction contract
- Consultation with owner during construction
- Review of shop drawings for compliance with design drawings and specifications
- Full-time or periodic field inspections of work in progress and reporting findings to owner
- Review and analysis of field testing reports
- Mediation to resolve disputes between owner and contractor
- Project start-up services
- Final inspection and project completion
5. Operational phase — In this phase, the engineer provides training to city staff to operate and maintain the project.
