The Challenge

Deliver an aviation‑ready structure with a massive clear span and strict performance criteria on an accelerated timeline. Integrate advanced mass timber systems with complex geometry, coordinate multidisciplinary teams, and adapt design‑assist workflows to support rapid assembly.

The solution

We leveraged a design‑assist approach to tackle the tight schedule and complex span. Our team engineered 210‑ft glulam trusses with custom connections, coordinated closely with architects and contractors, and pre‑fabricated components off‑site for rapid on-site assembly, ensuring precision, speed, and structural integrity.

The results

The project was delivered in under three months, the hangar balanced speed, precision, and sustainability. The structure’s innovative mass timber design achieved a landmark clear span, met client goals, and set a new benchmark for wood‑based aviation facilities.

Product Feature

Beams and Columns

Our beams and columns are architectural-grade glued-laminated timber elements crafted from premium Black Spruce SPF for strength, stability, and refined aesthetics. In this project, they form the primary structural framework while contributing to the warm, natural interior character.

Product Feature

Curved beams

Our curved beams are made from high-grade timber, offering the same strength and stability as straight beams with added architectural flexibility. In this project, they create elegant, flowing lines that enhance the overall design while supporting the structure.

Product Feature

Mass timber decking

Our mass timber decking is engineered from Black Spruce SPF to Douglas fir, to deliver both structural performance and a finished surface in one solution. In this project, it serves as the main roof deck, adding natural warmth while meeting fire and residential building standards.

Product Feature

Invisible connection system

Our invisible connection system conceals connectors within the timber, producing clean, uninterrupted surfaces while ensuring strength and durability. In this project, it allows for seamless wood-to-wood connections, enhancing both aesthetics and performance.

Product Feature

3D Curved beam

Our curved beams are made from high-grade timber, offering the same strength and stability as straight beams with added architectural flexibility. In this project, they create elegant, flowing lines that enhance the overall design while supporting the structure.

Product Feature

Round columns

Our round columns offer a great structural performance with added freedom for creative expression. In this project, the round columns echo the form of surrounding trees, helping the building blend naturally into its environment.

Product Feature

Creative form profiles

Our Creative form profiles lorem ipsum has been the industry’s standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. Lorem ipsum.

Product Feature

Prestige composite glulam

Our Prestige composite glulam combines a spruce core for strength with fine wood veneers for a distinctive architectural finish. In this project, it was used for prominent exposed beams, adding visual richness and highlighting the unique grain of the selected veneer species.

“Working with Art Massif on the Concord Hangar was a seamless experience. Their team’s expertise and innovative mass timber solutions made a complex project feel manageable, delivering a striking, high-quality structure on an exceptionally tight timeline.”
