Roads and Highways
Our firm has been involved in transportation work for state, city, county and township clients. More than 200 structures have been designed
by our staff, including bridges of various lengths, utilizing a variety of materials and construction procedures. Roadway projects have
included work on the Interstate System, U.S. and state highways, major urban projects, local streets, and rural highways. Work has included
underground utilities such as sanitary sewers, water main, and storm sewers, as well as parking lots, drainage studies and designs, and
field surveys. These project construction costs range from $10,000 to more than $100 million. Funding for these projects has included
federal, state, STP, MFT, and municipal dollars.
roundabouts
Roundabouts have been used throughout the world for decades and
are currently gaining popularity in the United States because
they are an innovative, cost-effective, safe alternative to
conventional intersection treatments, such as signals or
four-way stops. Roundabouts are innovative in that they
provide traffic calming, safety, aesthetic, and environmental
benefits while moving high volumes of traffic with minimal
delay. There are roundabout types to fit most traffic and
land use situations.
We are experts in all aspects of roundabout design from the
initial feasibility study to the final design and construction.
our experience includes more than 150 roundabouts in several
states. Our cutting edge knowledge has led Wisconsin
Department of Transportation (WisDOT) to select us for a
Specialty Master Contract to review roundabout feasibility and
design projects, to co-author the newly updated
roundabout section of the Facilities Development Manual, and
most recently, as Level 2 Qualified Roundabout Designers and
Reviews.
Traffic/Planning
We have extensive experience in computerized traffic modeling, intersection analysis, and signalization design. We also are fully familiar
with site and corridor analysis including traffic impact analyses,
transportation demand management plans, crash analyses, traffic flow analyses, and parking requirement inventories.
Bridges
We provide design and construction services for bridge rehabilitation. After an
in-depth inspection, our cost estimates have often justified rehabilitation over replacement. This option saves money and often can extend
the life of the structure another 20 years. In addition to an overlay or deck replacement, rehabilitation may include bearing replacement,
expansion joint replacement, surface repair to beams and substructures, railing replacement, and painting.

financed with local funds. In
addition to providing hydraulic reports, type studies, structure plans and specifications, and construction observation
services, these rehabilitation
projects have required the preparation of cost estimates and bidding documents.
