SENDRA meeting with Laing O’Rourke

SENDRA members have been invited by Laing O’Rourke, the construction company that is building the new Westgate center, for a short discussion about environmental monitoring.

The meeting took place on the 11th of March (2016) at the site offices. There were the Project Liaison Officer, the Sustainability Manager and two members of SENDRA.

SENDRA explained that there were concerns about possible worsening of noise, vibration and air quality due to the presence of the constructions. Laing O’Rourke representatives showed how the site is being constantly monitored thanks to two electronic equipments. Details about noise levels, dust and vibrations were discussed. All the figures and graphs shown by Lang O’Rourke proved that the measurements were below the fixed thresholds. The data was shown as daily or weekly averages, which do not exclude the possibility that occasional peaks get over the thresholds. SENDRA members were assured that, when peaks are detected, an alarm is produced so that corrective measures can be taken.

In conclusion, SENDRA members were satisfied by the levels of dust, noise and vibration being shown and were reassured by the monitoring measurements being put in place. Laing O’Rourke promised to publish regular updates about the measurements and to mention if any “exceptional” event might produce spikes and what actions are taken to keep them under control.

SENDRA and Clean Air UK measure air quality in the area

Some SENDRA members are worried about the impact of the Westgate developments and the increasing levels of traffic on the quality of the air they breathe.

SENDRA has established a collaboration with the Network for Clean Air UK, an Oxford based association that organises programmes of citizen science projects to measure air pollution. Network for Clean Air has kindly offered SENDRA two diffusion tubes for measuring the concentration of Nitrogen Dioxide, one of the main air pollutants generated by combustion engines.

Tubes were installed on the 10th of January 2016 in two locations: Thames Street and Dale Close. This way we will be able to compare the level of exposure to pollutants between homes close to the main roads and those a bit more inside.

The installed tubes will be removed at the beginning of February and sent to a lab where they will be analysed. Results will be distributed to SENDRA members as soon as they are available.
