I-76 Toll Plaza Reconstruction
ALCM, LLC (ALCM) construction management staff played a vital role in completing the $22 million reconstruction of the New Stanton Interchange/Toll Plaza and the reconstruction of the PA Turnpike MP 75.5 to 74.5 six months ahead of schedule and $300,000 below budget.
Major recommendations by ALCM that expedited schedule and reduced costs:
- Altered the sequence of construction for the three stage reconstruction from eastbound, westbound, center to westbound, eastbound, center. This change resulted in a considerable reduction in the amount of temporary pavement required to accommodate traffic movements by using existing pavement on the east bound side of the roadway.
- Use of rubblelized roadway concrete pavement to fill roadway undercuts in lieu of costly foreign rock borrow.
- Locating and identifying waste areas adjacent to the roadway alignment to reduce haul distances.
- Elimination of top soil in non critical areas to reduce costs.
- Elimination of geo-textile under roadway subgrade to reduce cost.
