Guernsey's airport closes for two days next week - but it will be far from peaceful.
From airport closing time on Monday, contractors will be working flat out - day and night - on the runway upgrade project.
All of the work will have to be finished by 6am on Thursday when the airport will re-open.
Airport director Colin Le Ray said there will be intense activity in and around the airport and has made an early apology.
"There will be a lot of vehicles moving around the airfield and site compounds at all times, and we apologise in advance for any disruption this might cause. We have to maintain good progress to ensure the runway reopens on time, but there measures will be in place to minimise any disturbance as best we can," he said.
Next week's work involves the runway edges, where it was widened in the past but constructed with different a foundation and thinner asphalt layer than the centre section. These need strengthening along almost the full length, before a new surface is overlaid at a later date.
All asphalt and concrete excavated in this operation will be reused elsewhere during the project.
During the closure Lagan will also complete the removal of contaminated soil from the airfield. This will be moved to the area between the main airport car park and Rue des Landes, and sealed in an impermeable lining along with material excavated in the previous closure.
The raised area outside the terminal, which has been removed in recent weeks, will then be restored and top soil reapplied in preparation for it to be grassed again.
"Construction activity will inevitably be evident around the airport for the duration of the project, but the restoration of the earth bund will be an improvement," said Le Ray and added: "There will be further requirements for night working in the coming weeks, prior to the start of the runway resurfacing which is expected will begin in July. Guernsey Airport has written to more than 800 homes in the vicinity of the airport, to update them ahead of the closure and provide contact details if they have any concerns".
