Aerospace Facility
General Electric
In order to support peak power demand at its aerospace facility, GE required a ventilation and sound attenuation solution for a new natural gas generator. This comprehensive solution needed to ensure that during those peak power periods, the facility met strict provincial noise regulations. Parklane achieved full compliance – all on time, on budget, and with zero on-site welding.
Overview
GE’s aerospace facility required a comprehensive ventilation and sound attenuation solution for a new natural gas generator used during peak power demand. In order to meet local noise compliance regulations, the ventilation system for the generator room had to incorporate advanced acoustical control measures.
Parklane was engaged early in the construction phase to design, fabricate, and deliver an integrated modular solution, including acoustic plenums and building ventilation silencers. Through a fully pre-engineered and prefabricated system, Parklane was able to streamline the installation process and support project schedule consolidation—ultimately reducing months of on-site labor while ensuring full acoustic compliance.

Project Challenges
Dual-Function Ventilation & Sound Attenuation
The generator required a robust ventilation system for cooling, but that same system had to prevent noise escape. The challenge was to create a design that delivered airflow performance without compromising the acoustical effectiveness of the solution.
Complex Integration Within a Coordinated Design Team
The project involved multiple technical teams including the mechanical consultant, acoustical engineer, and BIM coordinators. Parklane needed to ensure that their system aligned with mechanical, structural, and architectural components of the facility without creating interference or requiring rework.
Aggressive Construction Timeline & Site Constraints
With a tight schedule and a need to avoid costly delays, Parklane’s system had to be installable without field welding. It also had to be delivered in a way that minimized crane lifts and coordinated closely with the general contractor’s construction flow.
Project Solution
Design
Parklane designed a four-component modular system that integrated directly into the building’s structural and mechanical design:
Supporting Base Structure:
This structural platform served both as a suspension point for the silencers and a foundation for the acoustic plenum, simplifying alignment and load transfer.
Modular Supply and Return Air Silencers:
These were custom-fabricated to include integrated structural steel, allowing for rapid assembly and structural continuity.
Roof-Mounted Acoustic Plenums:
Each plenum was shipped pre-assembled with louvers, mechanical dampers, filter racks, architectural finishes, and all acoustical elements already installed—eliminating on-site complexity.
Integrated Room Ventilation:
Both supply and return fans were factory-installed into the silencers themselves, making the ventilation system plug-and-play upon arrival.
Installation
The entire system was fabricated off-site and delivered in a fully modular format. There was no field welding required, which allowed for faster installation and minimal disruption to other ongoing work.
Parklane worked closely with the project’s BIM team to perform regular clash analyses and coordinate the installation path to avoid conflicts with surrounding systems.
Community Response
While the primary concern was regulatory compliance rather than public impact, the solution ensured that generator operation would not contribute to noise pollution, maintaining the integrity of GE’s facility operations and supporting a positive relationship with regulatory stakeholders.
Results
The project achieved full compliance with local noise regulations for the generator ventilation system. Parklane’s pre-engineered modular solution reduced on-site installation time by several months.
By coordinating closely with GE’s mechanical, structural, and architectural teams, the final solution was seamlessly integrated into the facility without conflicts.
The client benefited from an acoustically compliant, efficient ventilation system delivered ahead of schedule, with the added advantage of long-term maintainability and operational reliability.
