Marshall Ridley Mixed Use Development CNIII & CNIV-R

ECC delivered a 200,000-square-foot mixed-use community that blends commercial space, multifamily residences, and townhomes into one cohesive campus. The wood-framed superstructure was built entirely with kiln-dried, fire-retardant-treated lumber and plywood for interior structural elements such as trusses, framing, sheathing, and the like. Then locked down by an engineered uplift-restraint roof package and an anchor tie-down system that protects every shear wall against overturning.  

A high-performance exterior envelope combines multiple cladding solutions in the right places: 5,000 SF of architectural metal panels, James Hardie lap and shake siding with stainless fasteners and color-matched sealants, and a fully detailed Huber ZIP Wall sheathing system whose taped seams and flashed penetrations create a continuous weather-resistive barrier. Commercial-grade windows and doors are set plumb and true, flashed with felt and self-adhering membranes, and tied into the ZIP layer for watertight performance.  

The 55,000-square-foot roof begins with a ½-inch DensDeck substrate and two 3-inch layers of polyisocyanurate insulation, shaped by ½-inch-per-foot tapered crickets for positive drainage. A fully adhered EPDM membrane, installed exactly to the manufacturer’s specifications and backed by a 25-year warranty, forms the primary weatherproof barrier. All curbs, terminations, flashings, and accessories were fitted per manufacturer details to create a continuous, watertight, code-compliant assembly. The townhome roofs are protected by 130,000 square feet of GAF asphalt shingles laid over a continuous self-adhering membrane underlayment. This combination provides a robust waterproof barrier and a durable, low-maintenance finish that meets manufacturer and code requirements. The 5,000 square feet of standing-seam metal roofing sit atop a continuous underlayment and ice-and-water shield, delivering robust secondary protection against wind-driven moisture. Panels are secured with manufacturer-approved clips and fasteners, and every penetration, transition, eave, ridge, and hip is precisely flashed per the manufacturer’s details to ensure a fully watertight, high-wind-resistant assembly. 

ECC ensured that all systems were installed according to the manufacturer's specifications, local building codes, and industry best practices. Proper integration of all components is critical for long-term performance.
