DDES provides interventoría (independent construction oversight on the owner's behalf) in Colombia: it represents the owner and makes sure the works are built to the agreed quality, schedule and cost, on public and private projects. It works from Barranquilla, with monthly reports, site minutes and quantity control.

What is interventoría (construction oversight)?
It is the control carried out by an independent professional, on the owner's behalf, so that the works are built according to the drawings, specifications and codes, at the agreed quality, schedule and cost. The NSR-10 defines the interventor as the person who represents the owner during construction, and includes quantity take-offs and administrative tasks in the role (A.13).
We represent the owner on site. We make sure that what was contracted gets built, to the required quality, on schedule and for the agreed price, on public and private projects.
How do interventoría, technical supervision and independent review differ?
| Interventoría (oversight) | Technical supervision | Independent design review | |
|---|---|---|---|
| What it controls | The whole construction contract: quality, schedule, cost, quantities and payments | That the structure and the nonstructural elements are built according to the drawings, designs and specifications | The structural designs: model, calculations and drawings |
| When | From the start of the contract to its close-out | During construction, before every concrete pour | Before the building permit is issued |
| Independence | Represents the owner before the contractor | Independent of the contractor (Law 400 of 1997, art. 37) | Someone other than the designer, with no employment relationship with the designer |
| Is it mandatory? | The NSR-10 does not require it: the owner or the contract decides | Yes, if the lot allows more than 2,000 m² (Law 1796), and for occupancy groups III and IV whatever the area (A.1.3.9.1) | Yes, if the lot allows more than 2,000 m² (Law 1796) |
| What it delivers | Monthly reports, progress and quantity minutes, close-out report | Release forms, materials control and a final report for the Certificado Técnico de Ocupación | Comments report and signed review statement for the curaduría |

Technical control
Quality of materials and workmanship, compliance with the specifications, and approval of each activity before it is paid.
Administrative and financial control
Progress minutes, quantities, change orders and contract balance. Every month, the owner knows how much has been built and how much is left.
Handover and close-out
Acceptance of the works, insurance bonds, manuals and contract close-out. We close the project with no loose ends.
What is the process?
Kickoff
Contract, bonds and schedule.
Follow-up
Site meetings and monthly minutes.
Control
Quality, quantities and payments.
Close-out
Acceptance, close-out and handover.
What do we deliver?
- Monthly oversight reports
- Progress and quantity minutes
- Schedule and budget control
- Opinion on change orders
- Close-out report

Frequently asked questions
How does it differ from technical supervision?
Technical supervision checks the structure against the NSR-10 and Law 1796. Interventoría controls the whole contract, with quality, schedule and cost, on the owner's behalf.
Do you work with public entities?
Yes. We know the reports and supporting documents that public contracts and oversight agencies require.
How often do I get reports?
A full monthly report, and meeting minutes every week or every two weeks, depending on the contract.
