Oscar Renda Contracting, Inc.

Oscar Renda Contracting, Inc. was established by Oscar Renda in 1974.  His brother, Rudolph J. Renda joined the business a few years later.  Having immigrated to the United States in 1956 as young boys with their family of two parents and five sons, their strong work ethic was born out of a desire to give back in appreciation for all this great country had given them in opportunity.  Oscar, being a high school football coach and U.S. History teacher, took out a teacher’s credit union loan for $13,000 in September of 1974.  Over four decades later and several billion dollars of heavy civil work completed, Oscar Renda Contracting is the foundation which helped create what Southland Holdings is today.

Southland Contracting, Inc.

Southland Contracting, Inc. was established in 1981 by Charlie Griffith.  Charlie was a true mechanical genius and could design, engineer, and build tunnel boring machines.  This gave him a very strong competitive advantage which allowed him to innovate and grow his tunneling company into a strong force in the industry.  His integrity, intelligence, and sheer strength of will continues to provide inspiration for all of the employees of this great company.  Charlie’s son, Clay Griffith, helps continue the legacy of innovation and successfully completing some of the most difficult and challenging tunneling projects in the world.

Johnson Bros. Corp

Johnson Construction company was established in 1929 by Walter D. Johnson.  Through several family generations and numerous triumphs and challenges, the fortitude of the company has been strengthened through the faith, grit, and resolve of the family’s leadership and the company’s hard working employees.  A leader in the industry with over 85 years of experience specializing in Bridge, Highway, Infrastructure, Marine, Industrial and Emergency Construction services for both public and private clients, Johnson Bros is poised to excel for decades to come building on the traditions established by the company’s founders and leaders.

Mole Constructors, Inc

Mole Constructors, Inc. was founded by Victor Scaravilli in 1974 to specialize in tunneling throughout the United States and Canada.  Victor, a graduate civil engineer, contributed numerous new and innovative approaches to the tunneling industry.  Victor is the inventor of the Jarva Hard Rock Tunnel Boring Machine (now the Robbins Company) and holds several patents.  Mole Constructors has very specialized knowledge, expertise, and skill in the tunnel market.  This provides dynamic capabilities rarely available in the industry allowing Southland Holdings to take on the most complex underground challenges and bore through them successfully.
