Tracking Site Balance at Pier 70 Project

Tracking Site Balance at Brookfield Properties' Pier 70 Project

Challenge

Site balance is difficult to track and critical to managing costs. Importing/exporting dirt can be 5-10x more expensive than relocating dirt on site. Developers rely on contractors for site balance information, which can be inaccurate and makes planning difficult.

The TraceAir Solution

On Brookfield Properties' 28-acre mixed-use development, Senior Project Manager David Greenstein used TraceAir to validate soil quantities on site and refine his plan to off-haul and/or import soil. Using weekly aerial images coupled with TraceAir's cut/fill balance tool, he was able to track soil movement on the project without relying on his general contractor. He was able to identify quantities of soil generated and repurposed on site, which could be reimbursed back to the project.

The cut/fill balance tool combined with timeline imagery created an efficient process to validate reimbursable costs.

TraceAir enables developers to look more frequently and easily at their site balance and predict where problems might be before they become costly. TraceAir gives developers the right knowledge at their fingertips so they are no longer reliant on contractors for information and can make proactive decisions.

TraceAir allows me to track accumulated soil and fill materials on site that nobody is accounting for. Without TraceAir, I would have been greatly challenged in proving these costs were reimbursable.”
