Client's Testimonial

"The 5D BIM service from Developers.dev was a revelation. For the first time, we had a live, dynamic view of our project's cost. It connected our design, procurement, and finance teams in a way we never thought possible. Their model became our single source of truth for all financial decisions, and the budget accuracy we achieved was unprecedented for a project of this scale."

Liam Chen, Director of Development

Client Overview

Our client is a prominent real estate developer in Australia, specializing in high-rise residential and mixed-use properties in major cities like Sydney and Melbourne. For a new 40-story residential tower, their primary objective was to maintain strict budget control from the initial design phase through to completion. Past projects had suffered from budget creep due to inaccurate initial estimates and the high cost of design changes identified late in the process.

Problem

The developer needed to move beyond traditional, static cost estimation methods. They required a dynamic system that could provide real-time cost feedback as the design evolved, allowing them to make informed, value-driven decisions early in the project lifecycle when changes are least expensive.

Key Challenges

Inaccurate Preliminary Estimates:

Traditional estimating methods were proving to be +/- 15-20% accurate, creating significant financial risk.

Delayed Cost Feedback:

The cost impact of design changes was often not understood for weeks, leading to rework or costly approvals.

Lack of Transparency:

Disconnect between the architectural model and the cost consultant's spreadsheet.

Complex Quantity Takeoffs:

Manually performing quantity takeoffs for a 40-story building was time-consuming and prone to human error.

Our Solution

Developers.dev was brought on as the strategic BIM consultant to implement and manage a comprehensive 5D BIM process. Our team worked directly with the developer, the architectural firm, and the appointed quantity surveyor.

Model-Based Quantity Takeoffs (QTO)

We developed the architectural and structural BIM models to a level of detail sufficient for extracting precise quantities for all major components (concrete, steel, façade panels, drywall, etc.).

Cost Data Integration

We worked with the client's quantity surveyor to link their cost libraries directly to the Revit model, assigning cost parameters to BIM elements.

Live Cost Dashboards

We used the model data to generate live cost dashboards in Power BI, allowing the client to visualize the budget breakdown by floor, trade, and material in real-time.

Value Engineering Scenarios

During the design phase, we modeled different design options (e.g., alternative façade systems, structural designs) and instantly reported on the cost implications, enabling rapid, data-driven value engineering.

Implementation and Execution

5D BIM Execution Plan

We began by creating a detailed 5D BEP that defined the scope, deliverables, and responsibilities for all stakeholders.

Model Structuring for 5D

We structured the BIM models specifically for cost extraction, ensuring all elements were modeled correctly and categorized for easy quantification.

Automated QTO

We created automated scripts to extract quantities from Revit and feed them directly into the cost plan, eliminating manual entry.

Bi-Weekly Cost Reporting

We held bi-weekly meetings with the development team to review the live cost model and analyze the financial impact of recent design changes.

Change Order Validation

During construction, we used the 5D model to validate contractor claims for change orders, ensuring they were based on accurate quantities.

Procurement Support

We provided the procurement team with detailed Bills of Quantities (BOQ) directly from the model, streamlining the tendering process.

Positive Outcome

98% Budget Accuracy

The final project cost was within 2% of the detailed budget established at the end of the Design Development phase, a massive improvement over the typical 15-20% variance.

$3.5M Saved in Value Engineering

The ability to rapidly test design scenarios enabled the team to identify over $3.5 million in savings without compromising on quality or design intent.

80% Faster Cost Estimation

The time to update the entire project cost plan after a design change was reduced from two weeks to less than a day.

Enhanced Stakeholder Confidence

The transparency of the 5D process gave the developer and their investors a high degree of confidence and control over the project's financial performance.
