Brief History

CSCI is one of the top construction companies in South Florida. We service large production home builders, high-end custom builders, and commercial and industrial general contractors. We operate statewide and have been thriving here in Florida for 30 years. At CSCI, we have earned a reputation among a distinguished list of returning clients who demand the best. We innovate, communicate, and are committed to unparalleled Quality, Speed, and Safety.

Ronald Goldburg and Mark Nuccilli founded CSCI in 1993. As a South Florida shell contractor, CSCI experienced almost instant success. We’ve led the industry in technological advancements and improved construction techniques for three decades. The scope of our work then was primarily the same as it is today. Through innovation and determination, CSCI grew rapidly during its first decade and then explosively during the real estate boom of 2000-2005.

In 2001, Ronald Goldburg’s son, Daniel Goldburg, currently CSCI’s president and majority owner, joined the company, building on the foundation of profitability and growth the company enjoyed under its founding leaders. Daniel Goldburg has focused the company’s mission on excellence in workmanship, over-delivery to partners and customers, and a culture dedicated to the benefit of employees and subcontractors first. Today, CSCI employs 125 team members, with over 1,500 subcontracted workers on its job sites daily, and completes over 4,000 residential shell houses annually.

Our Standards

CSCI President Daniel Goldburg leads by establishing a collaborative culture within the company, which empowers employees to succeed and deliver products with quality, speed, and safety.

“Our people,” Mr. Goldburg says, “are honest, direct, and professional. Success and growth in construction are functions of the people in the field, knowing the people in the office always have their safety and best interest in mind.”

At CSCI’s helm, Goldburg pushes advancements in technology and construction management to the next level, resulting in CSCI’s stellar reputation among employees, partners, customers, and industry insiders. These developments are the blueprint for success at CSCI and why the company has remained profitable each year since its inception.

Success and growth for the company and its customers, subcontractors, and partners despite a rollercoaster economy are why the most influential builders in the industry continue to return to CSCI for shell construction.

Why Choose Us

CSCI is one of the oldest shell contractors in Florida of our size and capabilities, with 30 years of experience improving, evolving, and perfecting our processes. Old, however, doesn’t mean we’re old-school. In fact, our company is quite the opposite.

CSCI employs an advanced estimating and workflow management software system for the industry’s fastest, most accurate bidding, production, and invoicing. Our bid accuracy is best in class for minimal waste and errors and spot-on pricing, saving our clients significantly on cost, time, and frustration.

After we bid and win, we transfer our material takeoffs into our production software, and each supervisor analyzes his job site via a custom tablet application, where he can place his orders directly with our vendors. Our supervisors also verify the completion of the work via our app, and we auto-pay our subcontractors.

This technology enables us to deliver faster, pay faster, and provide best-in-class prices to our customers while delivering with quality, speed, and safety.
