EXPERIENCE

Evaluation of potential borrow aggregate sources that were required for the construction of a pipeline in British Columbia was undertaken.  Work included high-level mapping, vetting of previous aggregate targets and development of new and alternative rock and gravel sites; mapping and exploration (test pits, drilling) and testing of samples; Acid-Rock Drainage assessments; permitting; mine design, closure/reclamation designs.

A landmark case in the High Court in Ireland in which the Plaintiff successfully brought a claim of unfit-for-purpose crushed rock fill that had been supplied by a quarry.  The Plaintiff proved his case that the rock was poor-quality stone that contained highly reactive framboidal pyrite that resulted in heave on the floor slabs, which in turn damaged the building.

Retained by Kanawha School Board to undertake an investigation of potential for pyritic heave of the on-site sandstone rock that was excavated and initially used as structural fill in construction of a new school.  Site investigation was carried out, followed by evaluation of the sandstone, which proved to have a potential for pyritic heave.
