This type of work includes roadway design for all urban highways with new curb and gutter and new or major reconstruction rural projects with substantial capacity improvements such as adding two or more lanes. Projects of this type generally include utility relocation plans, drainage design and permitting, maintenance of traffic plans, traffic engineering applications, intersection details, etc.

This type of work includes roadway design for rural RRR and minor widening and resurfacing projects which do not involve major reconstruction, new curb and gutter, or substantial capacity improvements. This work type also includes interstate projects involving resurfacing only. Projects of this type generally involve minor drainage, utility relocation, traffic operations improvements, miscellaneous design services, etc.

This type of work includes design of new and complex reconstruction projects on controlled access facilities including interstates, interchanges, and expressways. Projects of this type generally include the use of complex geometrics, substantial drainage evaluation and design features, permitting, traffic engineering applications, utility relocation plans, maintenance of traffic plans, interchange design, etc.

This group type of work includes the design of sound barriers, structural supports for highway signals, luminaries, and traffic signals.

This type of work includes the design of conventional, non-complex bridges and the structural design of other highway-related structures such as non-standard concrete box culverts and retaining walls. Generally, this group is limited to designs utilizing conventional foundation types, simple geometry, and having total estimated bridge(s) plan area(s) no greater than 100,000 square feet (sum of the areas of multiple bridges). Typically, this includes design for the construction, rehabilitation, widening, or lengthening of box culverts, retaining walls, cast-in-place or precast prestressed short span slab type bridges, simple span prestressed concrete beam bridges, and simple span I-beam bridges.
