More than a week in and — knock on wood — all is well with the concrete pour for the Muskrat Falls hydroelectric project, according to Nalcor Energy.

The milestone of first concrete was marked by the provincial Crown corporation Aug. 18 and The Telegram requested an update this week, checking into a rumour that was circulating of trouble on the job.

“To date, Astaldi has had three successful pours of concrete in the spillway and transition dams in this area of the site and Astaldi is making preparations for their next pour,” stated a spokeswoman for Nalcor, in an emailed response to questions.

“During startup of this type of work, it is normal to take time between pours to ensure all the technical and quality aspects of the formwork, reinforcing and the concrete production are taken care of. There’s nothing out of the ordinary that has happened during this time and process.”

The power facility will require concrete for spillway, powerhouse and dam structures. According to Nalcor, 560,000 cubic metres of concrete will be needed for the powerhouse and spillway structures alone. Another 200,000 cubic metres will be needed to build the dams.

Meanwhile, Astaldi has also seen to the start of the dome enclosure — being referred to as the Integrated Cover System (ICS) — meant to facilitate winter work at the site.

“Construction of the (enclosure) has begun with some components already erected by their contractor,” stated the Nalcor rep.

Quebec-based Constructions Proco has been contracted to do the design, fabrication and, now, installation work.
