As part of the final design phase, KMA provided supplemental and right-of-way surveys, subsurface utility engineering, geotechnical engineering, and pavement design. As part of these services, KMA established supplemental horizontal and vertical controls, as well as construction benchmarks, within the project limits.

KMA also determined the need for and performed subsurface exploration and in-situ testing to evaluate geotechnical concerns (e.g. foundation support, settlement, slope stability and ground water conditions); solicited proposals from qualified drilling contractors; performed twenty-two borings at the proposed locations of wing walls, abutments and retaining walls; and composed a Final Geotechnical/Pavement Design Report.  The report included results of the geotechnical investigations, analyses of foundation types, pavement analyses and construction recommendations (including results of field investigations, laboratory soil testing, and Dynamic Cone Penetrometer testing).
