How we started.

The company was formed in 2004 by Richard Kilcullen and Athole McDonald. Both directors are civil engineers and have worked together since 1988. The aim when they started the business was to dominate the medium sized civils market.

Both Richard and Athole are accountable to their clients for company performance and are very much actively involved in the day to day running of the business and maintaining working relationships with their clients. The success of the business is down to their dedicated, highly skilled, motivated workforce, market leading management and safety systems allows them to consistently deliver project safely, on time and on budget.

Our Culture.

At Kilmac, our culture is built on teamwork, integrity, and a commitment to continuous improvement. From day one, we’ve invested in developing a highly skilled, motivated workforce through structured training, mentoring, and clear career progression pathways. Many of our long-standing team members have grown with the business and continue to thrive in new roles and responsibilities.

Health and safety is embedded in everything we do and remains central to our success as we grow within Scotland’s mid-sized civil engineering market. We foster a positive, proactive safety culture across all levels of the business.

We are proud of our reputation for delivering projects to the highest standards — on time, within budget, and with a solution-focused approach to challenges on site. Our teams take ownership, collaborate well with clients, and are trusted to deliver quality every time.

Our Skill set.

Kilmac has established itself as a trusted and reliable contractor within the construction industry, known for consistently delivering high-quality results across a wide range of civil engineering projects.

Our experienced teams bring proven expertise in all core groundworks and civils operations, including earthworks, drainage, foundations, concrete works, slabbing, carriageway reinstatements, and hard landscaping. We have the capability and resource to manage complex site requirements while maintaining safety, efficiency, and attention to detail at every stage.

With a hands-on management approach and a skilled, committed workforce, Kilmac is well-equipped to meet the demands of both standalone groundworks packages and larger multidisciplinary projects.

Our Green credentials.

Kilmac is committed to driving sustainable change across our operations as we work towards ambitious carbon reduction goals. In 2022, our management team took a significant step by transitioning to an all-electric company car fleet. This includes vehicles such as Tesla, Kia, Mercedes, and Audi models, with charging infrastructure now in place both at home and across our workplaces.

We are also phasing out older vans in favour of more energy-efficient alternatives, including Renault Kangoo and Trafic models. Our wider fleet of over 50 vehicles is under ongoing review as we monitor rapid advancements in low-emission and electric vehicle technologies.

Beyond transport, we’ve made a substantial investment in renewable energy through the installation of our own 500kW wind turbine near Forfar. This not only offsets our energy use but makes a major contribution toward achieving a negative carbon footprint.

Environmental responsibility is embedded into our business decisions, and we continue to seek out practical, high-impact opportunities to reduce emissions and promote greener ways of working — both on-site and behind the scenes.

Looking to the future

In 2022, Kilmac began a carefully planned transition to an Employee Ownership Trust (EOT), marking a significant step in our long-term growth and succession strategy. This phased approach ensures continuity, stability, and continued success under the leadership of our experienced senior management team, with ongoing support and guidance from the founding directors.

The move to employee ownership reflects our commitment to empowering our people and securing the future of the business for the benefit of those who contribute to its success. It offers reassurance to our staff, clients, and partners that Kilmac’s values, culture, and high standards will remain at the heart of everything we do.

Employee ownership is a proven model that strengthens engagement, drives innovation, and supports long-term business resilience. As we look ahead, Kilmac remains focused on delivering exceptional service, building strong partnerships, and creating lasting value for our people, our clients, and our communities.
