They will be the nerve centres orchestrating HS2’s construction, containing everything from offices to living quarters.
And should the controversial train line get the green light, nearly 20 construction compounds could be in operation in our area within just a few years.
The compounds will directly manage the line’s construction. The bigger ones, such as the compound near Fleet Marston, will contain storage for bulk materials, offices, car parks, toilets and other welfare facilities, fuel storage, plant and equipment storage and even living accommodation.
Martin Wells HS2 Ltd’s petition manager for Bucks, said the final make-up of the sites has not yet been ironed out. But he added: “I would tell people to expect pretty much what you would expect from any major construction project. There will be security around it and hoardings. I would expect them to be well maintained.
“I appreciate some readers will have fairly limited experiences of living near these sort of sites but they are not unusual in places like Aylesbury with all the housing development going on.”
Construction of the line will generally take place from 8am to 6pm weekdays and 8am to 1pm Saturdays.
There will be of course be exceptions when activity goes on into the evening: “If we start pouring concrete we can’t stop and pour some later on,” said Mr Wells.
He said floodlighting the compounds 24/7 ‘is not in anybody’s interests’.
“We can provide security measures without going to those sort of extremes. We want to be a good neighbour. Each area has a liaison officer who is fully aware of what is likely to be going on at the site in the next week or months so they can have a conversation with interested parties to work out how it will impact on them and to make sure there doesn’t need to be more disruption than absolutely necessary.”
Most compounds will have between 100-200 staff at their peak. The number of cars and small lorries coming and going daily during peak times varies, but 190-260 at the main compound near Fleet Marston is certainly at the higher end.
The movement of construction vehicles will be confined where possible to specially made ‘haul roads’ running along the line.
However, it will still be necessary for HGVs to use public roads. The number of heavy vehicles going to and from compounds will usually reach around 20 at peak times but will reach an eye watering 730 per day at the Oxford Road compound near Fairford Leys due to its use as a ‘roadhead’ for the route-wide movement of earthworks materials.
Mr Wells said that compounds with residential accommodation have been built into their plans but it is hoped it can be avoided.
“We are not saying we will certainly have accommodation. If we can work around that we will do. It is not a given but it is possible.”
Should there be a need for living quarters, Mr Wells said they will be used during the week with workers going home at the weekend.
“What we are looking to do with the contractors is working out a best way for these people living on site to engage with local people.”
He said local businesses may welcome extra spending from workers coming out of the compounds, for example by spending their money in a restaurant or pub.
But he added: “The reality is it makes sense for these to be self-contained sites but I’m not suggesting people won’t come out of them under any circumstances.”
