McClure Wins 2026 CFSEI Award for Mountain Resort Roof System

McClure earned First Place in the Residential/Hospitality category of the 2026 Cold-Formed Steel Engineers Institute (CFSEI) Design Excellence Awards. The award recognized the firm’s work on Kindred Resort in Keystone, Colorado. McClure earned the recognition for engineering a cold-formed steel (CFS) roof system that overcame demanding snow, seismic and field construction challenges.

Kindred Resort required an exceptionally complex roof system. Vaulted ceilings, multi-plane geometry, long spans and integrated mechanical systems created significant structural demands. McClure engineered, detailed and modeled the stick-framed CFS roof system.

McClure engineered a complex cold-formed steel (CFS) roof system to meet demanding snow, seismic and architectural requirements at Kindred Resort.

Meeting Structural Requirements

Kindred Resort sits in a mountain ski community. Design snow loads range from 100 to 200 psf. McClure designed the seismic lateral force-resisting system to generate approximately 20-kip drag forces across the roof diaphragms. The mixed CFS and HSS roof framing also resisted vertical seismic loads reaching 80 kips.

The roof system incorporated 12-inch-deep, 97-mil CFS joists throughout the vaulted roof areas. These members integrated with MiTek CFS trusses and strategically placed HSS members.

Complex site conditions demanded extensive engineering coordination. The firm invested 1,800 hours across 21 engineers, detailers and modelers over three years. The effort produced 35 drawing revisions and resolved more than 100 field engineering issues during construction.

Resolving Field Challenges

The project’s defining achievement was the firm’s response to more than 100 field conditions discovered during construction.

Installers, inspectors and the general contractor encountered inaccessible weld locations, misaligned embeds and substituted clip types. They also encountered conflicting truss webs, missing members and unexpected penetrations.

The engineering team developed practical solutions for every condition. These repairs prevented demolition, minimized tear-out and preserved the predominantly CFS roof system.

Engineered detailing resolved field conflicts. The solutions maintained load paths, preserved CFS framing and ensured code compliance.

Engineering Connection Details

Several RediCor interfaces required engineering redesign after embeds and anchors differed from the original design. Engineered retrofit details restored structural performance without removing completed construction.

Limited weld access created additional challenges. Face-mounted plates transferred loads to accessible locations while avoiding unreliable anchorage conditions. Revised details also addressed stacked plates, weld sequencing and anchor layouts.

Field inspections identified incorrect clips, partial welds and improvised connections within inaccessible joist locations. The engineering team performed evaluations, including finite element analysis, to verify connection behavior and fastener force distribution. ClarkDietrich tested several field-installed clip configurations.

The evaluations demonstrated that many modified connections remained structurally adequate. This eliminated costly retrofits while maintaining code compliance.

Engineers also evaluated joists for web crippling on a case-by-case basis. The evaluations reduced the number of required field corrections.

Preserving a CFS-First Roof System

The vaulted roof geometry created complex collector, drag and diaphragm conditions throughout the structure. Several drag elements turned corners and followed the vaulted roof geometry. These conditions required highly coordinated detailing to maintain continuous load paths.

The firm also adjusted drag routing to maintain diaphragm continuity without affecting the architectural design.

In several locations, drag lines did not extend to the roof edge as shown in the structural plans. Rather than removing completed wall assemblies, the firm engineered retrofit details that restored continuous load paths.

The roof system also carried vertical seismic forces reaching 80 kips. The design maintained a CFS-first structural strategy by introducing HSS trusses and ridge beams only where necessary. The selective use of HSS preserved the efficiency and design logic of the CFS framing system.

Award-Winning Engineering

McClure developed more than 100 engineered field solutions during construction. Each solution preserved constructability, maintained structural performance and kept construction moving.

Kindred Resort demonstrates how delegated CFS engineering can solve complex field conditions without sacrificing schedule or structural integrity. The project also highlights technical discipline, responsive engineering and practical detailing under demanding snow, seismic and architectural conditions.
