Preou in Central London
In central London we completed the mechanical services for an office fit-out at 30 City Road and the mechanical, ventilation and controls works at the Greenhouse Centre on Bell Street.
Central London projects mean restricted deliveries, tight plant routes and close coordination with other trades. Our engineers travel from Billericay, about 23 miles away, and projects are managed by a named contracts manager from first survey to handover.
The buildings we work on in Central London are mostly office floors, sports and community venues and listed buildings. They are occupied buildings, so the works are planned in detail before we start on site: shutdowns agreed in advance, heavy work programmed into holidays or quiet periods, and temporary plant where heating or hot water has to stay on.
