Portland Natural Gas Transmission System Project
Trans Quebec & Maritimes Pipeline Limited Partnership (TQM) proposed to construct and operate natural gas transmission facilities that would extend its then current system from Lachenaie located on the north shore of the Rivière des Prairies, east of Montreal to East Hereford near the Canada-U.S. border. At that location, TQM would connect to the facilities of the Portland Natural Gas Transmission System to serve the U.S. Northeast markets. The facilities would also serve the existing market of Gaz Metropolitain Inc. through a new delivery point at Waterloo, Quebec.
The project was divided into three spreads to be constructed concurrently.
The first spread covered the first 15 km of the route, from Lachenaie to Boucherville, including work on the Island of Montreal and the surrounding areas. The second spread covered 88 km, from Boucherville to Waterloo. The third spread covered approximately 112 km from Waterloo to East Hereford.
In addition, directional drilling was performed for the major watercourses, a number of smaller watercourses, as well as some major road crossings and a golf course. Directional drilling activities were not included in the subcontracts for individual spreads. Rather, this work was subcontracted for the entire project.
During the execution of the project, the contractor encountered schedule and cost overruns. Some of the issues allegedly encountered include late and out of sequence issuance of permits and reduced width of clearing in wooded areas.
Revay and Associates was retained by legal counsel for TQM to review the claim and present its evaluation in the form of an expert report. Specifically, Revay was asked to comment on schedule and cost overruns. Our mandate required that we:
- Prepare an as-built schedule for the purposes of analysis;
- Perform a delay analysis comparing the as-planned and asbuilt schedules;
- Prepare a history of interferences;
- Render an opinion as to the ability of the contractor to meet its schedule but for the owner responsible issues;
- Arrive at a quantification of the contractor’s claim.
