Our work
Complex jobsites, delivered on time and safely. A spotlight on the projects that illustrate AMNC's field expertise in industrial mechanics.
Dismantling and reassembly of two 120,000-pound trommels
As general contractor, AMNC led the complete dismantling of an existing installation and the assembly of two new trommels — steel-sizing machines — on an active industrial site in Montréal. Full reconditioning of conveyors, heavy angled lifts, hot work and multi-party logistics coordination, from mobilization through demobilization.

From equipment arrival to commissioning
A complex jobsite on an active operating plant
Safety first
Heavy use of torches, grinders and welding — on a site where flammable material is spread throughout. Fire risk linked to hot work was the number-one issue to control.
Heavy angled lifts
Overhead installation of two 120,000-lb trommels, on top of dismantling the existing conveyors to the top of the columns. Two to three cranes a day, plus aerial lifts spread across the jobsite.
Tight schedule
The client needed to restart production as quickly as possible. Every step — mobilization, lifts, hookups, commissioning — had to flow without slippage.
General contractor, from mobilization to demobilization
Sealed engineered lift plans
For every major piece of equipment, procedures and lift plans sealed by professional engineers — executed to the letter. Both trommels were lifted into place at angle, on schedule.
Hot-work procedures
Before the first spark: permits, fire watch, blast screens and cleared zones. Good procedures, locked in early, kept the team efficient with no fire incident.
Multi-party lift logistics
Coordinated lift plans with Mammoet for the cranes, and specialized trailers brought in from Ontario to haul the trommels. Loading, install window and sequencing — all held.
Dismantle, recondition, reassemble
Everything down to the top of the columns was dismantled to start fresh: a full reconditioning of conveyors and all mechanical equipment, then reassembly and commissioning.
Project delivered, production restarted
Beyond the original scope. Several contractual additions were absorbed mid-project to better serve the client — without slipping the original schedule. The client was able to restart production in the best possible timeframe.
In our specialists' own words
We delivered a project on time, within the agreed schedule, with no incidents, no accidents. Health and safety was executed extremely well, with everyone's collaboration. What mattered most was that everyone goes home at the end of the day.
In our general-contractor scope, we put a lot of procedures in place to control jobsite risk. Being prepared, with good procedures, is what let us work efficiently and deliver in the time that was allotted to us — mission accomplished.
