The news is a boost for a company which was forced to announce 10 redundancies late last year after unexpected delays in the award of multiple construction contracts.

Six months on, group director Athole McDonald confirmed the picture is much brighter, with a record £20m annual turnover now projected for the firm’s construction arm and a lucrative joint venture providing a timely cash injection to its development business.

He said: “There is a real air of positivity within our company following the joint venture agreement we recently struck with Muirhall Energy to deliver the £50m Glen Ullinish wind farm project on the Isle of Skye.

“We have been working towards this for eight years. It has the potential to become one of the most productive onshore wind projects in the UK and one the country’s first subsidy free onshore wind projects. 

“A four-year grid connection delay had tied-up our initial seven-figure investment but now, with partners Muirhall Energy, we are planning to use our mutual strengths and complementary skills sets to deliver the project in 2023.

“This deal guarantees the financial security to deliver a route to market for the Glen Ullinish project in a post-subsidy era and provides stability for the Kilmac group in what are still uncertain times for the wider construction industry.”

Mr McDonald said Kilmac Energy’s experience in delivering its own £2.5m Finavon Hill wind project in Angus would prove vital in the 42-megawatt Skye development.

He revealed Kilmac, which employs around 100 staff in from its Perth and Dundee offices, has looked beyond its traditional Tayside hunting ground to secure new business opportunities.

“We have picked up strongly after the traditional Christmas seasonal lull,” Mr McDonald said. “We have been moving beyond what had been our traditional geographic area, expanding our horizons and forging new relationships.”

Mr McDonald and fellow director Richard Kilcullen anticipate creating up to 30 new jobs when an £8m deal to carry out the groundworks on the new Madras College in St Andrews is signed off in the next few weeks.

“This promises to be the biggest job we have ever handled and will also provide security for the existing workforce in the longer term,” said Mr McDonald.

“We are also delighted to continue our excellent relationship with Dundee City Council as main contractor on the Camperdown Car Park upgrade. We can also confirm our first tie-in with new clients, Maxi for a new primary school in Menstrie and Hadden Construction’s affordable homes development in Crieff’s Pigeon Row.”

Kilmac has been given the green light to commence a £1.5m groundworks for the Robertson Eastern contract for a new John Clark BMW/Mini franchise at the former Lochee Juniors football ground in Dundee’s Kingscross Road following the successful delivery of the adjacent Jaguar Land Rover project. 

“We have also started a major groundworks project for another new client, the Clugston Group, at their exciting £210m energy from waste plant at Grangemouth,” confirmed Mr McDonald.
