The old firehouse reconstruction project held special significance for the client. It aimed to preserve the historical significance of a building in Ridgeway, Colorado, while transforming it into a restaurant and multi-family residential complex.

The ORIGIN team was assigned to develop a structural model and produce a comprehensive set of structural drawings. Our project scope encompassed creating structural cover sheets, isometric steel model views, foundation plans, dimension and embedment plans, plans for CMU walls, typical details, and submittals review, to name a few.

Throughout the project, the ORIGIN experts had to closely cooperate with the Colorado construction project’s structural engineers, ensuring aligned expectations and high-quality output.

Input: Markups provided by structural engineers.

Project deliverables:

  • Structural model and drawings;
  • A set of approx. 40 construction documents.
Subservices: Construction drawings, PDF/CAD to BIM conversion
Industry: Mixed-use
Object type: Mixed-use
Area: 2727 m² / 29360 ft²
Tools used: Autodesk Revit
Project stages
1. Initial modeling and drafting based on project inputs
2. Iterations based on feedback from the structural engineer
3. Coordination of models and drawings with architecture
4. Submittal review
5. Iterations based on architect/owner changes

Step 1 — Drawings generation

We started with schematic plans for foundations, framing, and general details, gradually refining and expanding our drawings to archive a complete set of structural drawings.

During the drawings generation process, we actively coordinated with structural engineers to address any potential issues between structural and architectural designs. Additionally, we communicated mismatches between directions and redlines.

Through numerous iterations, we progressed from the initial 15-sheet set of schematic plans to a comprehensive 39-sheet set of construction documents.

Step 2 — Adaptations to the underpinning method

Throughout the project, it became evident that changes to the underpinning method were necessary.

Since only preliminary surveys of the existing building had been conducted prior to the beginning of construction, it was now discovered that both the top and bottom of the structure required a slightly different approach. The preferred changes were communicated with the architectural team. As a result, revised drawings with new plans and details were issued, with revisions clearly marked and tagged.

Step 3 — Compliance and quality control

Our team collaborated closely with the structural engineer to ensure that the model and drawings adhered to all required standards and codes.

We meticulously reviewed and incorporated all markups and comments provided by the engineer to develop a highly functional and reliable structure.

Step 4 — Submittals review

We were also tasked with accurately coordinating the steel shop drawings with the structural drawings and the structural model.

This required a high level of attentiveness and accuracy from our team, resulting in having us review the size, location, elevation, and extent of each structural element. After carefully analyzing all the aspects, the ORIGIN team handed over all questions and comments to the structural team for further review and clarification.

Construction process

Our collaboration didn’t end after completing the drawings.

Throughout the construction phase, our team provided ongoing support to the project by issuing drawing revisions in response to site, architectural, and engineering changes.

We considered the project complete only when the last nail is hammered.
