Air Quality Monitor Exceedances - Kirtling

  • 23/02/18 & 14/04/18
  • Caused by number of large items of plant on site restricting access for our
  • Roadsweeper. Damping down is also carried out.
  • 21/04/18
  • Exceedance caused by timber works underneath dust monitor to provide

formwork/shuttering for a concrete slab pour.

Community Survey

Doing well

Communication Keeping noise to a minimum Communication and tidiness Things are better now, less traffic coming down Kirtling Street so thank you for improving that Minimising disruption Updates Communication is excellent. Site traffic is managed well

Community Survey

Room for improvement Changes made

Digging earth at 3am in the morning. It keeps me awake. I thought there was a 10pm cut off time Several changes made to the barge loading operation (as discussed) Noise, especially during the night Night noise due to barge loading operations considerably reduced following mitigation measures Bus stop cleanliness Dedicated road sweepers clean every day Stop the noise at night after 11pm Changes made, as above Not enough information to put forward a view Proposal to change survey to capture distance from site. Info Sheets hand delivered to wider radius The construction level of noise across the water is unacceptable. Concerns from north of the river due to barge loading

  • perations, mitigated as discussed

The roads around the site are dusty and feel unsafe with the amount of HGVs, but I realise these are also from other sites nearby. Would like more communications. Strict logistics procedure limiting delivery times, numbers, no idling, vehicle routes etc Struggle in to cope with upwards light pollution. Security lighting needs to be downwards only and we have been promised hoods for the strip lights and trialled various blackout blinds but don’t solve the issue Security continue to implement blackout blinds on evening shifts and angle lights downward Working to a tighter, definite schedule Follow schedule as tightly as possible more communications with upcoming works and progress

  • Parking. Workers who are waiting to be picked up and leave a lot of

rubbish around where they are waiting Site workers know not to wait or idle. Travel survey undertaken, share results next session The main thing is the noise from the rubble landing as it drops from the conveyor belt on to the barge Potentially work from another site OR barge loading operation which was mitigated
