Public Safety is Our Priority
Our goal is to meet or exceed client expectations and deliver projects on time and within budget.
Our professional staff has comprehensive expertise in highway design, traffic operational analysis, traffic design, drainage analysis and design, minor structural design, environmental assessments and project coordination, including initial funding, final design and construction observation.
Using a multidisciplinary approach to problem-solving, we provide creative and comprehensive solutions to challenging projects. Having an integrated team of licensed professionals- engineers, geologists and surveyor- allows for seamless distribution of project elements between teams and improving design continuity.
Developing close working relationships and encouraging client participation allows our experts to focus on developing and executing projects that result in practical solutions to complex engineering problems. Many staff members have practical work experience at a local, state or federal DOT allowing a common perspective on resolving problems prior to construction.
Specific skills and services we provide to Transportation clients:
SMA has been called upon to provide design and construction solutions for projects of all sizes:
Small projects requiring quick response, cost-effective design and construction plans
Large projects involving thorough evaluation of all design options, traffic / pedestrian safety, mobility for multiple modes of transportation sensitivity for cultural resources, biological conditions and public involvement
Recent design experience includes rural highways through difficult mountainous terrain, major urban arterial and collector streets and major traffic controlled signalized intersections of state highways.
SMA was, and currently still is, the on-call consultant for ITS assignments through the Department’s Traffic Management Center (TMC). Through the ITS on-call, we have developed ITS standard drawings, prepared specifications, developed fiber optic splicing plans, prepared system expansion plans, and managed the construction of ITS projects. We have also developed the designs for dynamic message signs (DMS), traffic surveillance cameras, and automated vehicle count installations. Additionally, we prepared the DMS operations manual now used at the TMC and throughout all six district offices to define the appropriate use of DMA in normal day-to-day operations, and "emergency" conditions.
The first 0.4 miles of this project was a five-lane urban roadway with sidewalks, curb and gutter. The highway transitioned to a rural roadway with center left-turn lanes and then to two twelve-foot driving lanes. The existing roadway was showing signs of subgrade failure and pedestrian facilities were not ADA-compliant. Existing storm drains were undersized.
The new design extended the five-lane urban roadway section north approximately 0.7 miles. The design included reconstruction of the existing pavement in the urban section and pavement rehabilitation for the northern 3.6 miles of rural highway. A new traffic signal, a new storm drain, sidewalk and ADA ramps were constructed though the first mile. Bicycle lanes were included.
SMA takes pride in designing safe, modern and multi-modal transportation infrastructure for DOTs. Our local presence, knowledge and experience enables us to be efficient and effective in delivering your next project.
