How a job in Southend-on-Sea works
Assess
We work out how many people use each space and the fresh-air rate needed.
Design

Balance
Air flows are measured and balanced to the design.
Local points to consider
Noise
Fans and grilles are selected and attenuated to keep noise down.
Roof and height work
Flat roofs, high walls and atriums need the right access equipment and edge protection. We plan towers, MEWPs or scaffold before the job, not on the day.
Heat recovery
Bringing in cold air in winter costs energy. Heat recovery units reclaim much of it.
Working hours
Most Southend-on-Sea businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
