Some projects are more than concrete and steel. They're the heartbeat of a city.

Landmarks like the Downtown Boise YMCA are where community is built. It’s where families connect, goals are achieved, and the city's future takes shape. As a Boise firm, we feel a profound sense of pride and responsibility when we help bring these essential spaces to life.

Our role was to provide the structural engineering, but our motivation was to build a stronger Boise. Seeing this vision become a vibrant reality for our neighbors is the ultimate measure of our success.

We are honored to be part of the team that delivered this incredible asset to our downtown core.

Set in the heart of downtown Boise, The Mill Apartments project redefines city living with 233,700 square feet of vibrant, mixed-use residential space. Developed in partnership with Cushing Terrell and design-build partner Engineered Structures, Inc. (ESI), this 3-over-1 podium structure delivers modern apartment living above ground-level amenities and integrated parking, merging efficiency with urban energy.

The design features a post-tensioned concrete transfer slab at the first floor, supporting four levels of wood-framed residences above. Engineered for durability and code compliance within Boise’s evolving urban fabric, the structure is optimized for performance and streamlined construction.

Axiom is providing comprehensive structural engineering services, including permit-ready drawings, integrated specifications, and LOD 200 BIM modeling for collaborative design alignment. Our team participates in regular coordination meetings, conducts up to five site visits, and supports responsive shop drawing and RFI reviews to ensure construction stays on track.

With its scale, speed, and seamless design-build delivery, The Mill Apartments will stand as a model for next-generation downtown living, and Axiom is proud to build its structural foundation.

Integrated Steel Delivery (ISD) is Axiom’s forward-thinking approach to structural engineering, designed to combat today’s market challenges of material escalation and long lead times. By integrating design and construction workflows through our IPD (Integrated Project Delivery) model, we help project teams accelerate critical steel procurement and reduce cost unpredictability from the outset.

Through a strategic partnership with 22-year steel veterans at Evolve Steel, Axiom enables early-stage steel procurement, shop drawings, and concurrent detailing, all before final trade partners are on board. This proactive strategy shortens schedules, controls risk, and improves budget confidence for owners and contractors alike.

Our ISD method hinges on four key elements: target value budgeting with BIM-driven system selection, pull planning to align design with construction milestones, early material orders that preserve flexibility while advancing procurement, and turnkey steel solutions powered by Tekla Fabrol for seamless fabrication and er****on.

Trust Axiom’s Integrated Steel Delivery to streamline your structural timeline, protect against change orders, and ensure smarter steel outcomes, faster.
