Stage 1 - Pre-Design
The Pre-Design stage includes selection of the consulting engineer and negotiation of the design contract; field surveys; property and right of way research; utility investigations; and geotechnical investigations.
Stage 2 - Preliminary Design
During the Preliminary Design stage, the consulting engineer performs engineering design sufficient to produce preliminary roadway and drainage plans. Those plans are reviewed by the Engineering Department and comments are returned to the consulting engineer for revisions and refinement of the design.
Stage 3 - Final Design
In the Final Design stage, the consulting engineer incorporates comments from the Engineering Department and from regulatory agencies into detailed final roadway and drainage plans. The final plans contain roadway plans, profiles, cross sections, details, and construction quantities which can be used for right of way acquisition, permitting, and bidding for construction.
Stage 4 - Permitting
Depending on the location and type of project, as well as the scope of the project, permit applications are submitted for one or more of the following:
Stage 5 - Right-of-Way Acquisition
In cases where the project requires the acquisition of additional right of way and/or easements, the appropriate documents are prepared and distributed to the affected property owners. If property owners have questions about the documents or the project, they are encouraged to contact the Engineering Department or the consulting engineer. The timely return of the right-of-way documents is critical to the construction schedule.
Stage 6 - Construction
Bid documents are prepared and construction contractors are invited to submit bids to construct the project. Based on an analysis of the bid results, a recommendation is made to County Council for awarding the construction contract. The selected contractor begins construction, which typically continues for three to six months until completion.
