Planned Remedial Works and Upgrades
When it comes to urgent, high-risk or large-scale works on gas, water, steam, oil or compressed air systems, we are the go to supplier for commercial mechanical electrical work. Our engineers are fully equipped to manage complex installations, upgrades and system modifications under extreme pressure conditions, safely, efficiently and with minimal downtime.
We deliver commercial and industrial mechanical solutions across East Anglia, North London and Kent, working for borough and county councils, public sector facilities and private clients operating critical infrastructure.
What Planned Remedial Works Cover
Our planned remedial works and upgrade services ensure the safety, compliance and performance of vital building systems. We handle both proactive and reactive upgrades, including:
- Gas mains and high-pressure pipeline installations
- Steam and condensate systems
- Compressed air and vacuum lines
- Water and oil supply infrastructure
- Plant room upgrades and refits
- Commercial heating and hot water systems
- Ventilation, extraction and air handling systems
- Boiler replacements, flue installations and system balancing
We take responsibility for every stage of the project, from initial investigation and design through to installation, testing and certification.
Example of a Planned Remedial Project
In a recent project, our engineers upgraded a major site’s gas infrastructure by installing a 6-inch bypass line to improve efficiency and simplify maintenance.
To prevent operational disruption, the system was prefabricated off-site and installed over a single weekend. The bypass design now allows the main gas system to operate at reduced demand without booster assistance, cutting energy use and streamlining ongoing maintenance.
Key aspects of this project included:
- Full gas purge using purge fan and flare stack to ensure safe working conditions
- Off-site fabrication of pipework, valves and purge points for precision and speed
- Controlled cutting into existing pipework, verified as gas-free before works began
- Coordination with the building’s maintenance team to maintain safety and cleanliness within a listed environment
The upgrade was completed ahead of schedule, without disruption, and has improved both system efficiency and long-term maintainability.
Planning and Preparation
Every remedial or upgrade project begins with a detailed assessment and site survey. Our engineers measure and evaluate existing systems to develop a tailored solution that improves efficiency, maintainability and safety.
Where possible, we prefabricate pipework and assemblies in our in-house hot works facility, allowing us to complete installations quickly on-site. This controlled approach minimises downtime and ensures quality workmanship throughout.
Safety and Compliance
Safety is at the core of every Olympus project. All gas and mechanical systems are installed and tested to Gas Safe, OFTEC and Building Regulations standards.
Our engineers are trained in live system work, enabling them to handle high-pressure environments such as gas mains, steam lines and compressed air networks with full compliance and control. Each installation is supported by detailed method statements, risk assessments and certification on completion.
