"We try to do the distancing thing, we're having to wear masks and gloves and wash our hands regularly, and sign-in/sign-out boards. You can no longer leave site and come back. So home made lunches, stay healthy."
Horne said while they have managed to pick up this job where they left off, the future's not so clear.
"A lot of people are a little bit hesitant to commit at the moment with the financial situation and also with their jobs," he said.
"We've had our next jobs basically put on hold - we don't have a job to go to after this unfortunately. A bit of a waiting game, I guess."
It's something a lot of the industry is grappling with - to what extent the scale of the economic downturn will hit different areas of the sector.
Construction Industry Council chair David Kelly, who is also chief executive of the Registered Master Builders Association, said how many future projects will come through the pipeline was unknown.
"The big issues are the forward work programme. [I'm] not hearing a lot of drop offs for confirmed clients who had already completed design. It's really those future clients, that's where the big focus will turn to over the next few weeks," Kelly said.
One large company - Naylor Love - has already had a commercial client press pause, and was worried another might do the same.
Chief executive Rick Herd said while the government is able to fund and fast track public sector jobs like schools, hospitals and roads, the private sector doesn't have the same security of funding.
He worried about job losses at scale if there isn't financial stimulus for private construction from the government.
"It's certainly a possibility if there's no means to effectively stimulate private sector investment," Herd said.
"We need to see some positive action in the next two or three weeks or month to see what actually [the government is] going to do to stimulate that private sector investment."
Kelly said the next 12 to 18 months will be critical, as an industry with half a million people directly and indirectly employed watches on.
