In a letter to residents, HS2 officials warned they have to move an underground gas pipeline and said that work will include boring tunnels underground.
Two phases of work will begin between mid and late August, though no specific date was given.
Any works that do not involve tunnelling will be carried out between 8am and 6pm on weekdays with a period of up to one hour before for start-up activities and one hour after for close-down activities such as deliveries, unloading and maintenance, residents were told.
Patricia Thompson, senior engagement manager for HS2, said: “The start-up and close-down periods will not include the operation of any plant or machinery likely to cause disturbance to local residents or businesses.”
Engineers will be installing a new gas pipeline from south of the existing Chiltern Mainline to join the existing pipeline to the south-east of the Dogs Trust on Harvil Road.
The letter explained: “The pipeline is an important supply for London and we need to carry out this diversion to continue to ensure a safe and reliable gas supply to the area. While we do not anticipate these works to cause any major disruption or for there to be any effect on local gas supply, we recognise the disturbance this work can create and apologise in advance.”
Some equipment from the tunnelling operation will be visible from Harvil Road, officials said.
Ms Thompson said: “While the tunnel boring machine is operating, we may need to work 24-hours a day.
“However, as this work is underground we do not anticipate any noise or disruption for local people, although you may notice people on-site during the night or in the early hours of the morning.
“We’ll be setting up a construction site off Harvil Road, across from Harefield Oil Terminal. All of our site, equipment and work will be taking place within HS2 land.
“To ensure the safety of road users and our engineers, we will be installing temporary traffic lights near to the site office on Harvil Road.
“We’ll only need to use these during our working hours and when our contractors need to access the site. We apologise for any disruption this causes.”
