01 · Scope
Nature and scope of this code
MARA Limitada, a construction company founded on November 26, 1987, and domiciled at Carrera 8 # 16-61, Office 202, Tunja, Boyacá, Colombia, adopts this Code of Ethics voluntarily. It is not required by law: it sets out how the company has chosen to work and the standards it holds itself to.
The code applies to MARA’s partners, managers and employees across all projects, and is actively promoted among subcontractors and suppliers as a condition for a lasting business relationship with the company.
02 · Compliance
Regulatory compliance
MARA performs public works contracts. That fact alone sets a standard: complying with the Colombian law applicable to each project in contractual, labor, environmental, tax and social security matters, with no shortcuts and no self-serving interpretations.
When a project is governed by special rules — such as those applying to the protected areas where the company frequently works — MARA undertakes to learn them before starting work and to adapt its operations to them throughout execution.
03 · Anti-corruption
Zero tolerance for corruption
MARA does not offer, promise or give money, gifts, favors or any other advantage to public officials, independent construction supervisors or contract supervisors in order to obtain contracts, influence decisions or speed up procedures. Nor does it accept them from third parties.
The company takes the bribery-prevention standards of Colombian Law 1778 of 2016 as a benchmark of good practice, even in areas where that statute is not directly enforceable against it. Anyone acting on MARA’s behalf must be able to account for any payment or expense connected with a procurement process.
Participation in selection processes is based on truthful information: real experience, real capacity and prices prepared with technical rigor.
04 · Transparency
Transparency with contracting entities
In its dealings with public entities, independent construction supervision firms and contract supervisors, MARA provides complete, accurate and timely information: work progress, technical difficulties and any events affecting the schedule or budget. Hiding a problem never solves it; documenting it in time protects the project and all parties involved.
Project records — site logbooks, minutes, reports, correspondence — reflect what actually happened on site. No one at MARA is authorized to alter, omit or fabricate contractual information.
05 · Communities
Relationship with communities
MARA’s projects are carried out in inhabited territories: local, Indigenous, Afro-Colombian and rural farming communities that were there before the project and will remain after it. The company treats them as neighbors and hosts, not as an obstacle to the work.
This translates into concrete practices: listening and responding to community concerns, giving priority to local labor and services when the project allows it, respecting local customs and practices, and preventing any conduct by staff that disrupts community life in the area of influence.
06 · Environment
Respect for the environment in protected areas
Building inside protected areas is a privilege that demands a higher standard than conventional construction. MARA plans and carries out its activities to keep the footprint of each intervention to a minimum: rigorous waste management, control of discharges and noise, protection of the surrounding wildlife and plant life, and use of authorized work areas only.
Personnel entering a protected area receive specific instructions on what is and is not allowed. Extracting, purchasing or transporting wildlife or plant specimens from the area is prohibited, as is any use of natural resources beyond the authorized performance of the contract.
MARA complies with the management plans and guidelines set by the environmental authority for each project, and understands that handing over a project in a protected area includes returning its surroundings in the agreed condition.
07 · OHS
Occupational health and safety
No schedule or cost target justifies putting a person at risk. MARA manages occupational health and safety in accordance with applicable Colombian regulations: hazard identification before each activity, adequate personal protective equipment, workforce training and immediate correction of unsafe conditions.
Every worker has the right — and the duty — to stop an activity they consider unsafe and to report it without fear of retaliation. Projects in remote or island locations, which are common in MARA’s work, are planned with enhanced protocols for logistics, communications and emergency response.
08 · Equity
Equity and fair treatment
MARA does not tolerate discrimination on the basis of gender, ethnicity, origin, age, beliefs, sexual orientation or social status, and rejects all forms of workplace or sexual harassment. Hiring, pay and promotion decisions are based on merit and performance.
In a historically male-dominated industry, 58.3% of MARA’s team are women. This is not a quota: it is the result of hiring based on ability. The company is also committed to the timely payment of wages and social security contributions for all its personnel.
09 · Reporting
Reporting channel and current version
Anyone — employee, subcontractor, supplier, community member or member of the public — may report conduct contrary to this code by writing to protected email. Reports are received in good faith, handled confidentially and do not give rise to retaliation against the person who submits them. For general matters concerning the website and the company, protected email and phone +57 311 244 5992 are also available.
The personal data of anyone who submits a report is processed in accordance with MARA’s Personal Data Processing Policy.
This code is a living document: MARA’s management reviews it periodically and updates it when project experience so requires. Current version: July 2026.
