|
The use of EIFS on One Seven at Belleview Station exemplifies the value of prefabrication in contemporary construction. By integrating aesthetic flexibility, technical innovation, and logistical efficiency, EIFS helped the project team deliver a complex, multi-clad façade ahead of schedule, within budget, and to a high standard of quality. The success of this project serves as a benchmark for future mixed-use developments seeking to leverage the advantages of modern EIFS technology.

Project Overview
One Seven at Belleview Station is a high-end, mixed-use development located in South Denver’s Belleview Station district. Designed as a modern urban retreat, the project comprises 250 luxury apartments, office space, a spacious lobby, and a suite of amenity areas. The building’s architecture emphasizes contemporary design elements and dynamic façade articulation, with strategic use of multiple cladding systems. |

Scope of EIFS Use
A total of 885 prefabricated panels were installed on the project, including 692 EIFS panels and 193 backup panels. The integration of Exterior Insulation and Finish Systems (EIFS) played a critical role in meeting both aesthetic goals and performance requirements. The prefab approach was instrumental in ensuring budget compliance and accelerating the construction timeline.

Aesthetic Appeal and Design Integration
The One7 project demanded a sophisticated, multi-cladding façade with distinct zones:
The One7 project demanded a sophisticated, multi-cladding façade with distinct zones:
- The Podium: Ground-level brick façade utilizing backup panels with welded brick ledger angles for field-installed full brick.
- The Back Bar: A 17-story north-facing tower clad in light grey EIFS panels accented by darker grey finishes.
- The Cube: An 8-story block of luxury apartments suspended above the amenity deck, finished with bright white EIFS panels and decorative brake metal.
- The Zipper: A transitional section of backup panels with field-applied metal finishes connecting the Cube and Back Bar.
Innovation and Creativity
Complex geometry and detailing required advanced planning:
Complex geometry and detailing required advanced planning:
- BIM Coordination: Every panel type and interface with adjacent materials were modeled in detail using BIM, ensuring precise alignment and reducing on-site rework.
- Radius Wall Construction: The Podium’s curved walls (252' radius) were executed with segmented backup panels and integrated steel ledger angles to support the brick veneer—highlighting the flexibility of prefabricated systems.
- Layered Façade Depths: Multiple EPS thicknesses were used to create architectural reveals and depth variations around window assemblies.
- Integrated Systems: Design and detailing were tightly coordinated with other trades and design teams to resolve complex intersections—such as DAFS ceilings—ensuring system continuity and waterproofing integrity.
Challenges and Resolutions
The owner’s demand for an accelerated project timeline created a unique set of logistical and execution challenges:
The owner’s demand for an accelerated project timeline created a unique set of logistical and execution challenges:
- Compressed Schedule: The baseline schedule was already expedited by adopting panelized EIFS; however, the owner further incentivized a two-month acceleration.
- Performance Under Pressure: Through efficient planning, coordination, and just-in-time panel delivery, the panelizer achieved dry-in and exterior finish completion one month ahead of the already-reduced schedule.
Functionality and Performance
EIFS contributed to superior project outcomes in multiple dimensions:
EIFS contributed to superior project outcomes in multiple dimensions:
- On-site Efficiency: Prefabrication minimized staging needs and congestion on the jobsite.
- Installation Safety: Reduced labor and time at height enhanced worker safety.
- Consistent Quality: Factory-controlled fabrication ensured high-quality finishes and minimized field variation.
- Thermal Performance: EIFS provided continuous insulation and contributed to the building’s energy efficiency goals.
