Our company currently has a full time staff of over 20, including partners, engineers, draftsmen and administrative personnel. All are widely experienced in the development of large projects. One thing that sets us apart is that each project is led by one of the partners, who is in close contact with the client, always available, anticipating needs and ready to solve problems quickly and effectively. Something in what we diferenciate, from other structural consultants, is the efficiency of the final cost of our structural designs, which allows our customers to be more competitive. In International IECA we are committed to our clients to achieve the most efficient direct "gray work" direct costs in the market, complying with all current design codes and without lowering the quality standards of the buildings.
