Warman and Martensville Interchanges

Warman and Martensville, SK

The Warman Martensville Interchange project began in 2017 as a three-year design-build contract to construct new highway interchanges for the cities of Warman and Martensville.  KPCL was subcontracted by Kiewit to perform the earthworks scope of work, which involved excavation/ placement of 1.15 million cubic meters, 1,600 meters HDPE culvert for drainage systems, pavement structure grading including sub-base and base materials equating to 352,000 tonnes, final topsoil placement on 146 hectares, and various earthworks support on the overpass structures.  In total, KPCL constructed over 26 kilometers of new roadway in two construction seasons, allowing the project to be completed a year ahead of schedule. Completed by December 2018, the new interchanges help reduce traffic congestion and provide safer access into both communities.

Highways 18 and 39 Subgrade and Surfacing Structure

Estevan and Bienfait, Saskatchewan

With KPCL as the prime contractor, construction started in 2016.  The scope of work consisted of the removal of the existing road surface structure and subgrade and the construction of new subgrade and surfacing structure for 12.86 kilometers of Highway #39, east of Estevan. In addition, the scope included 3 kilometers of intersection improvements at the junction of Highway #39 and #18, the demolition of a concrete mine haul road underpass bridge, the installation of geotextiles to bridge over poor areas of subgrade, installation of a mechanically stabilized earth wall using cold weather materials, and the supply and placement of a surfacing structure consisting of sub-base and base granular aggregates prior to paving. Earthworks totaled over 1.2 million cubic meters of materials placed.

Key challenges included planning and implementing a significant number of traffic accommodation zones to allow for simultaneous multi-work areas, while minimizing impact on traffic, locating and conditioning sufficient quantities of fill for the construction of the embankments, working through environmental regulatory requirements, and meeting a compressed construction schedule.
