Construction and Fabrication Services...

El Dorado is primarily identified as a heavy industrial contractor. Most of our projects, including engineering and installation details are developed in-house to complement our construction requirements. Whether it is engineering analysis or drawing development, we use AutoCad 2000 program to help accomplish the task at hand. We have also used our engineering capabilities in our EPCC contracts. For larger engineering projects, we often join with Stateside Engineering Firms that have specific experience related to the project at hand.

El Dorado's original specialization was the construction and maintenance of API above ground storage tanks for the petroleum industry. Our expertise in this area continues to be a focal point of our business. We have erected tanks from 20 feet in diameter to 240 feet in diameter.

With few new tanks being built in Puerto Rico and the Caribbean, most of our tank services involve maintenance. All tank repairs are performed according to the API 653 standards. We are qualified to perform tank bottom and roof replacements, shell repairs, structure replacement, etc.
