Thank you for Subscribing to Construction Business Review Weekly Brief
John R. Medina, Founder and Senior PrincipalThis team brings a combination of knowledge and expertise gained over years of experience in the industry. MCWC’s experience is built from the curtain wall experts who built the early high rises in the ‘90s, the mid-modern high rises and the mid-rises of New York, Chicago and Boston. Today, they collaborate on high-profile projects designed by internationally acclaimed architects from around the globe.
“Regardless of the complexity of the project, we remain committed to delivering the highest quality service,” says John R. Medina, founder and senior principal. “Our work culture is truly different from any other consulting firm in the U.S.”
The Miami-based company is reshaping how building envelope consulting companies operate through its distinct approach, providing clients with industry-leading exterior wall, technical glazing and waterproofing support. MCWC’s specialized testing capabilities have earned it certifications for wind and water testing on tall buildings.
Weathering Storms with Resilience
Each year, South Florida faces extreme weather conditions, including hurricanes and heavy rainfall, which present substantial challenges for high-rise buildings. MCWC takes into account external stresses like rotational movements and inter-story displacement to ensure long-term structural integrity and occupant safety
MCWC works closely with architects to ensure the development of water-tight buildings. The company collaborates with architects and developers to design custom curtain walls and glazing assemblies tailored to each project’s unique requirements. Its expertise includes below-grade and above-grade waterproofing solutions, advanced air vapor systems, glass railings and cladding protection—all engineered for long-term durability and optimal performance.
A persistent challenge in the region is the risk of mold and mildew resulting from water infiltration, which can pose serious health hazards, especially for individuals with respiratory conditions. To combat this, the company employs a proactive strategy, designing hermetically sealed buildings that enhance energy efficiency while effectively preventing water intrusion.
Once the construction phase begins, MCWC visits the site and conducts inspection services to ensure all installations are completed as planned. The absence of routine maintenance after construction is a key factor affecting a building’s longevity and is often misinterpreted as a structural defect. By educating building owners and developers on the importance of regular upkeep, the company helps prevent unnecessary repairs and legal disputes.

MCWC also offers forensic investigation services to assist in cases involving hurricane damage, insurance claims and latent defects. Leveraging its team’s specialization in chemistry and statistics, the company helps determine the root causes of issues like water infiltration and structural failures through post-occupancy building examinations. In-depth analysis helps uncover past mistakes, enabling developers and contractors to devise preventive measures that influence future projects.
Teamwork Makes the Dream Team
At the heart of MCWC’s success is its team headed by Medina and senior associate principals María Moral and Guillermo Saavedra, who have been with the firm for over two decades. They are licensed architects, supervising over 40 projects at any given time. Guided by a pioneer in window and wall testing technology, Medina has developed unparalleled expertise. Leading by example, he takes a hands-on approach to every project, personally conducting thorough inspections to ensure the highest standards.
Over the years, MCWC has left a lasting imprint on some of the world’s most sophisticated landmark buildings. Dedicated to striking the perfect balance between aesthetics and functionality, the company continues to serve clients with best-in-class services.
