The company was founded in 1999 and is engaged in a full scope of Civil Engineering activities: public buildings, roads and infrastructure, residential buildings, system-intensive buildings, building conservation, treatment of urban / regional master plans and more.

Project Management

Our Project management is based on many years of experience and a full integration between design, management, supervision, control and auditing. The fact that our managerial team is experienced and continues to be involved in the practice as well as in the control only upgrades and reinforces the management quality with the years.

The Company is specialized in the implementation of engineering control of building and infrastructure tenders and has a high professional capability in the audits of partial and final accounts.


In view of the specialization of the Company in Project reviews, our US Sister Company has been established in January 2014.
