Featured Projects

The objective of this project was to analyze and improve the pavement grading by milling, wedge and leveling, and overlaying the asphalt pavement along a portion of Mt. Harmony Road between Valley View Court and Rue Court in Calvert County, Maryland.  Several crashes had been reported in this location as a result of excessive speed by drivers for existing conditions.  An analysis was performed to determine if the horizontal curve alignment could remain substantially the same within the existing right-of-way and improve the curve’s design by grading the asphalt pavement with super-elevation.  

The scope of work for this work project was to complete the design to re-construct the curve section to improve the geometric design features, such as super-elevation and cross section.  The survey department at Development Facilitators, Inc. (DFI) was responsible for the field run topographic survey of the outer edge of pavement, centerline of the road and inner edge of pavement including spot elevations, right-of-way and adjoining property determinations and deed mosaics.  Based upon the survey data collected and meetings with the Calvert County’s Department of Public Works staff, DFI prepared and submitted preliminary plans, specifications, and construction cost estimates for the design concept per the requirements of the Calvert County Road Ordinance and the Construction Standards.

Upon review and approval of the preliminary plans, DFI proceeded with final design, maintenance of traffic plans, engineer’s cost estimates, and the preparation of right-of-way plats for grading easements and associated written descriptions and all associated design documents for review and approval by the County.  Upon final approval, DFI provided the County with the necessary survey stakeout and cut-sheets for construction.
