Built on a Simple Construction Reality: Most Technical Work Never Needed to Be on Site.

We provide mid-size industrial contractors with the technical services, work packaging, and project controls capacity of a major EPC — scaled to your exact project duration, on your working day.

01 / The Founding Story

A question asked by a U.S. construction manager.

A former project manager in the United States was staffing a demanding industrial expansion and needed an experienced technical field engineer. He reached out to Javier Buelvas, who had already managed complex multidiscipline industrial projects alongside him on past work.

When he learned Javier had returned to his home base in Colombia, the conversation nearly stopped — there was no administrative mechanism to hire foreign expatriates to site. Then he asked the question that created this company:

"Couldn't you do this from Colombia?"

It turned out that almost every deliverable that bottlenecks a superintendent or frustrates a project controls manager doesn't require boots on the site. It requires experienced engineers who understand construction, work inside the contractor's platforms, and operate during the same business day. That first scope was executed through RP Construcciones y Equipos SAS — an established Colombian contractor with the engineering personnel and process control the work required. TSC was founded to institutionalize that answer.

02 / Our Core Principles

How we work with project teams.

The field is the customer.

If a package doesn't make a foreman's Monday easier, it isn't complete.

Find it on the screen, not on the site.

Every clash or missing bolt set resolved digitally saves thousands in standby time.

The data tells the truth first.

We reconcile actual installation against plan while correction is still cheap.

Coverage without headcount.

We scale up for a release or turnaround, and down when the scope closes.

We say what we do not do.

We are not the Engineer of Record and do not sign stamped designs.

Repaying our sponsor's reputation.

Every client came from a manager who staked their credibility on us.
