Project overview

285 tons of steel. 4,000 hours of technically demanding detailing.

The Highline Residences is a new residential development located at 98 Aspen Ridge Drive in Mountain Village, Colorado. It is the first new condominium development in the community in more than a decade.

The project comprises 16 three- to five-bedroom residences with private outdoor spaces, heated parking, elevators, and optional private hot tubs. Working with Western Slope Iron & Supply, our team provided structural steel and miscellaneous metals detailing for approximately 285 tons of steel.

Although the project’s tonnage was relatively moderate, the combination of a fast construction schedule, ongoing concrete work, timber framing, complex roof geometry, and repeatedly revised stair systems required approximately 4,000 detailing hours.

Detailing scope

Structural steel detailing scope.

01

Structural and miscellaneous steel

Approximately 285 tons of primary steel, stairs, railings and secondary metal components were developed within one Tekla model.

02

Steel-to-timber interfaces

Steel supports, connection locations and member elevations were coordinated with the building’s extensive timber framing.

03

Multi-slope roof framing

Roof members were modeled across changing slopes and elevations, including their relationships with the timber structure.

04

Stairs and revised support conditions

Stair framing, landings, railings and connections were updated through repeated engineering reviews and RFI responses.

Technical complexity

Coordination and detailing challenges.

01

Steel releases during concrete pours

Concrete construction was already underway when detailing began. Critical steel information needed rapid review and release to support continuing site work.

02

Hybrid steel and timber construction

The two framing systems had to align geometrically while accounting for their respective connections and installation requirements.

03

Changing roof planes and elevations

The complex roof introduced varied steel-to-timber interfaces and conditions requiring three-dimensional clarification before release.

04

Repeated stair engineering revisions

Numerous stair RFIs and recalculations had to be incorporated without losing coordination with floor levels, openings, framing and finishes.

Our approach

Coordinating structural steel with extensive timber framing.

A substantial portion of the building was designed using timber construction. This required extensive coordination between the structural steel, wood framing, and miscellaneous metal components.

Steel members and connections had to integrate with timber elements while accommodating the geometry and installation requirements of both systems.

The Tekla model provided a coordinated three-dimensional environment for reviewing these interfaces and developing the fabrication information required by Western Slope Iron & Supply.

Coordination included:

  • Structural steel and timber interfaces
  • Steel support conditions for wood framing
  • Miscellaneous metals integrated with timber construction
  • Connection locations and member elevations
  • Architectural and structural requirements
  • Construction and installation sequencing

Stair systems requiring repeated engineering review.

The steel stair scope presented additional design and coordination challenges. Stair framing conditions generated numerous RFIs and required several rounds of engineering review and recalculation.

Revisions had to be incorporated into the model while maintaining coordination with:

  • Floor and landing elevations
  • Structural framing
  • Timber construction
  • Architectural openings
  • Guardrails and handrails
  • Adjacent walls and finishes
  • Connection and support conditions

The stair design issues were resolved through continued coordination with the engineer and contractor.

Structural and miscellaneous steel in one coordinated model.

Tekla Structures was used to develop the project’s structural steel and miscellaneous metals within a coordinated model.

Maintaining these elements together helped the detailing team manage the relationships between the main frame, timber structure, roof framing, stairs, railings, and other secondary steel components.

The model served as the basis for coordination, RFI review, revision management, and production of fabrication and erection information.

Project result

Lessons from a fast-paced, hybrid structure.

The Highline Residences reinforced the importance of flexibility and responsiveness when detailing steel for an active construction schedule.

The project also provided valuable experience in:

  • Coordinating steel with timber structures
  • Managing complex roof geometry
  • Prioritizing releases around ongoing concrete pours
  • Responding to numerous RFIs
  • Incorporating repeated engineering revisions
  • Resolving steel stair design conditions
  • Maintaining clear communication with the fabricator, engineer, and contractor

Strong teamwork and proactive coordination were essential throughout the detailing process.
