Your Projects’ Environmental Questions Addressed…
It is our responsibility to assess and manage the impact of our works on the immediate environment, this enables us to plan and adopt the most beneficial course of action in reducing dust, vibration, exhaust emissions and noise pollution generated by our works.
We own a large selection of the latest monitoring and recording devices with our environmental staff fully trained in its operation and report generation.
Over the years, we are proud to have received many safety and environmental awards from clients and various associations, including the Corporation of London where we received the very first ‘Corporation of London Award for Environmental Management and Innovation’.
Dust and exhaust emissions are monitored on a daily basis for the duration of any project by our site management team and where necessary, Baseline air quality monitoring equipment is installed.
Control measures include building facades encapsulated in debris netting and Monarflex sheeting to minimise the release of dust to external areas. Concrete debris is dampened down during the demolition process and before being crushed for re-use and/or loaded for disposal.
Asbestos containing materials are removed under fully controlled conditions, within purpose built enclosures by our Asbestos Removal Division. The burning of any demolition waste materials is strictly forbidden.
We recognise the harm caused by exhaust emissions. Plant and vehicles are therefore fully maintained, serviced and never left needlessly to idle. Our plant operates on Low Sulphur Red diesel, every machine where appropriate being fitted with Diesel Particulate Filters.
In liaison with the professional team, site noise monitoring schemes are developed from the outset. Baseline noise monitoring is undertaken prior to works commencing, followed by noise level assessments from individual demolition processes and traffic movements.
Readings are taken daily by either hand held monitors, or a semi-permanent monitoring installation both inside and outside the site boundary.
SMS and Email alerts support an effective monitoring and management system.
John F Hunt also operate ‘Noise-Hub’, which is a noise measurement system communicating with single or multiple monitoring terminals. The software allows us to communicate with our monitors, download, calibrate and create a variety of automated reports, which are transmitted directly to any laptop, pc, tablet or smart phone.
When required we install ‘Live Time’ vibration monitoring via permanent stations installed either inside or outside our structure.
As with noise, baseline readings are taken prior to works commencing, followed by assessments to determine vibration levels from falling debris, lorry loading, operational plant and demolition activities in general.
The battery powered or mains units monitoring units have a built in GSM function allowing remote access and downloading of the seismograph memory, with high and low level text alerts, enabling constantly updates.
To ensure impacts are minimised we implement strict control measures during the demolition of all structures.
Ecology, Biodiversity & Wildlife
Most species of animals are protected under the Wildlife and Countryside Act 1981, therefore prior to any demolition works commencing on site, a full ecology survey of the building and surrounding area is undertaken, particularly if there are any adjacent derelict areas, grasslands, woodlands, rivers and canals.
During demolition, if any protected species of animal or its habitation are discovered, an independent and licenced ecology consultant will be retained to undertake a survey of the site, to identify both protected and invasive species of flora and fauna. The works methods would then be updated as required to comply with the Wildlife and Countryside Act 1981.
We are keen to contribute to the reduction of carbon emissions and minimise our footprint. By recording the amount of electricity used by each company, means of travel and fuel consumed to operate site plant, generators, commercial vehicles and company cars, this enables our in-house Environmental Consultants to determine our current carbon footprint rating.
We have introduced full wireless telemetry monitoring technology on all new items of heavy plant, thus allowing instant fuel consumption and performance analysis. Data is relayed to the site supervisor’s device, showing an energy saving report, documenting CO2 emissions, working hours, idling, digging and travelling time. This facilitates maximum use, minimal downtime and also shows any preventive maintenance that can be done, helping them run more efficiently.
