One of Markosky’s most recent projects was the SR 0980, Section 139 project included the realignment of the southern approach of PA 980 to form a ‘plus’ intersection and constructing a new bridge carrying the Montour trail over the intersection to fully separate trail-using families, pedestrians and bicyclists from surface motor vehicle traffic. The new 379’ bridge is a three-span composite steel girder structure, which provides the necessary vertical clearances for both PA 980 and PA 50 while meeting the Trail’s requirement of a maximum approach grade. The new bridge also completes the final Montour Trail gap in Washington County, the heavily traveled central part of the Trail.

The project incorporated numerous innovative and unique aspects including the adaptive reuse of the only remaining portion of the original two-girder structure built in 1913 by the Montour Railroad. Additionally, the project incorporated geosynthetic reinforced slope (GRS) embankments for the trail approaches in order to increase the clearance of the new bridge over the roadways without increasing the embankment footprint thereby avoiding impacts to adjacent properties and the environment.

Markosky invests in our future by supporting groups that benefit children such as the Laurel Highlands Council Boy Scouts of America, Community Foundation Alleghenies, Dreams Go ON Trail Ride, STAT, Inc. LVHS Alliance of Student Athletes, Ligonier Camp & Conference Center to name a few.

Staff members mentor 7th & 8th graders in a project-based learning program. Students use their imagination, research, and engineering design to compete in the completion of a model Future City Tests of Engineering Aptitude, Mathematics, and Science (TEAM+S). This national engineering competition involves problem-solving skills, collaboration, analytical thinking and multidimensional problem-solving solutions. Moving to the high school level, Markosky provides job shadowing opportunities for career exploration. At a corporate level, they participated as a “Speed Coach” for Mentoring Monday event hosted by the Pittsburgh Business Times bringing women together to network, receive career advice, tips and guidance.

The firm volunteered their services at a tree planting event for Flight 93 Memorial Planting Day hosted by the Marcellus Shale Coalition.

Markosky was recently awarded the 2017 Business of The Year Award from the Westmoreland Chamber of Commerce for delivering quality projects, supporting future generations in the sciences and being a steward in the community,

Client Spotlight – Earth Inc.

Earth, Inc.Earth, Inc. is a geotechnical engineering firm that has specialized in highway, bridge work and large scale commercial development since its inception in 1983. The company can provide the complete geotechnical scope from initial field reconnaissance, problem definition, development and monitoring of subsurface exploration programs, laboratory testing, conceptual design, alternatives analysis including cost comparisons, sketch design, pre-final design, final design, and consultation during construction.

Earth, Inc. is accredited by the AASHTO Material Reference Laboratory (AMRL) Accreditation Program for soil testing for both AASHTO and ASTM test methods. The company has maintained the longest accredited program for soil testing in the state of Pennsylvania. There is a laboratory QA/QC program in place including technician training and evaluation, AMRL proficiency testing, and equipment calibration.

Geotechnical and supplementary civil engineering service highlights include:

  • Geotechnical investigations for civil engineering construction
  • Foundation investigations for civil structures including buildings and bridges
  • Geotechnical engineering design including dams, impoundments, site development, roadways, retaining structures, etc.
  • Hydrologic studies and hydraulic analyses and design
  • Groundwater studies
  • Landslide stabilization
  • Acid mine drainage and mine reclamation projects
  • Consulting, monitoring, and testing services during construction

Their many highway and bridge projects include work on Pennsylvania Turnpike expansion projects including the Mon Fayette, Greensburg and Beaver Valley Expressways. In addition to PennDOT reconstruction projects on I-79 and I-70, they have also worked on Pennsylvania Turnpike Mainline and Northeast Extension reconstruction projects as well.

McCandless Crossing, a large scale commercial project located in the North Hills of Pittsburgh, represents recent commercial property development with which Earth, Inc. has been involved since the beginning of the project. Site work design began in 2006 with several phases of grading and subsequent building construction having occurred in the time since. Prior to developer improvements, Earth Inc. worked with highway design consultants, the Town of McCandless and the Pennsylvania Department of Transportation to widen McKnight Road, Cumberland Road, Babcock Boulevard, and Duncan Avenue, thereby increasing traffic capacity via new turn lanes for the massive undertaking.

Earth, Inc.The Duquesne Incline on Mt. Washington is an iconic symbol in Pittsburgh. In 1996, the Incline experienced a significant rock fall event. Although the Incline did not incur much damage, its long-term stability was threatened. As a result, Earth, Inc. designed a rock fall remediation system consisting of slope netting and rock bolts on two rock faces of suspect stability on the very steep hillside overlooking downtown Pittsburgh; this work also included shotcrete underpinnings of rock overhangs. The construction work was incorporated into the Port Authority of Allegheny County’s contract to perform hillside stabilization along portions of the Conrail railroad shelf.

For ongoing safety and monitoring, Earth, Inc. designed a geotechnical instrumentation system for the hillside upon which the Incline is located, consisting of 10 tilt meters attached to exposed rock faces. Continuous remote reading of the tilt meters is received over time at the upper station of the Incline with automated output being generated to provide baseline data for future comparisons. Alarms have been built into the computerized system to alert Duquesne Incline personnel if unusual movement has occurred, along with providing a warning of possible impending major hillside movement.

Upgrading highways and bridges, creating new commercial communities and stabilizing iconic symbols of Pittsburgh and beyond are among the highlights of Earth Inc.’s geotechnical service capabilities.
