Denver Multi-Use Development

Project Overview

Location: Denver, Colorado Type: Mixed-Use Commercial Development

This Denver mixed-use development combines residential and commercial occupancies within a single multi-story structure: a project type that demands careful structural coordination between the different loading conditions, floor-to-floor heights, and code requirements that each occupancy brings.

Mixed-Use Structural Considerations

Mixed-use buildings are structurally complex because the commercial floors at grade often have different geometry, span requirements, and loading than the residential floors above. Ground-floor retail or restaurant space typically requires longer spans and higher floor-to-floor heights than the residential units stacked above it. This mismatch in column grid and structural depth must be resolved through a transfer system: beams or walls that collect loads from the residential column pattern and redistribute them to the wider commercial column spacing below.

Frontier provided structural consultation during the early design phase to evaluate the feasibility of the proposed building geometry, identify the transfer system approach, and establish the structural framing concept that the design team and owner could move forward with confidence.

Coordination with Architecture

Multi-use buildings require close coordination between the structural engineer and the architectural team. Structural depth (how thick the floor-ceiling assembly is) directly impacts the floor-to-floor height and, therefore, the overall building height and unit count. Early structural input on beam depths, column locations, and shear wall placement allows the architect to optimize the building section for both structural efficiency and rentable area.
