Project Overview

A site utilities firm needed expert BIM support for a large residential development spanning over 1,054,670 sq. ft. in Caldwell, ID, USA. The project covered complex drainage and water main systems across 251 units. With only partial inputs and a 10-day deadline, our 3-member team delivered an LOD 300 Revit model. All systems were accurately modeled, slopes were maintained, and files were delivered on time.

Why the Client Needed Help

Tight Submission Deadline

The project required full site utility modeling within a strict 10-day turnaround window.

Incomplete Design Inputs

Only one-third of the architectural model was shared, limiting reference data for accurate modeling.

Complex Drainage System Requirements

The drainage network included intricate trench systems and catch basin layouts needing careful coordination.

Critical Water Main Depth Compliance

The water main had to run exactly 48 inches below the top of the asphalt throughout the site.

Asphalt Slope Alignment Challenges

Maintaining vertical offset while tracking the asphalt slope added significant technical complexity to the model.

Scope of Work

Site Utilities 3D Modeling

Drainage System Modeling

Water Main System Modeling

Key Project Challenges

Limited Model Data

Only partial architectural input was available when modeling began.

Water Main Depth Accuracy

Ensuring a consistent 48-inch offset below the asphalt surface throughout.

Drainage Network Complexity

Modeling interconnected trench and catch basin systems with correct slopes.

Asphalt Slope Referencing

Aligning the water main precisely with a variable asphalt slope across the site.

Deadline Pressure

Delivering a complete and accurate model within a 10-day project window.

Our Project Execution Strategy

Our team leveraged advanced BIM tools and professional expertise to model complex site utilities with precision. Despite limited inputs, we maintained high accuracy, met compliance requirements, and delivered the model on schedule.

Client Testimonial

"We were a bit concerned about handing this off with so little data and such a tight window. We only had part of the architectural model ready, and the water main depth requirements made things even more demanding. But the team handled it without any back and forth. They understood the slope referencing issue right away and came back with a clean, accurate model. The drainage layout was exactly what we needed. Delivered on time. That kind of reliability is hard to find. We will definitely be bringing them in on future projects."
