About Us


Pinnacle Groundworks was established in 2017 by Michael McDonnell and Fergal McDonnell, bringing together their extensive experience of over 60 years in the groundworks industry. Their vision was to create a company that would provide a modern and professional service, overcoming the challenges of an ever-evolving construction industry. Through their strong industry connections, Pinnacle Groundworks quickly emerged as a leading groundworks contractor in London and the South East.


Today, our business takes pride in our team of seasoned senior managers and directors, each possessing extensive expertise in diverse aspects of the industry, such as construction, project management, and project delivery. Each member of our high-performing team excels in their respective fields and consistently proves their adaptability to the dynamic demands of the industry. With the added advantage of our builders-yard in North Kent, we have the necessary space, accessibility, and ambition to further expand.


At Pinnacle Groundworks, we pride ourselves on maintaining the highest standards of professionalism. Both our management and on-site teams adhere to strict codes of conduct and policies. We have earned prestigious accreditations such as SMAS, SafeContractor, and SafePQQ. Furthermore, our management systems have been developed over the years to meet the stringent requirements of ISO9001, ISO14001, and ISO45001, culminating in our achievement of these accreditations in June 2022.


While primarily operating in London and the South East, we are also capable of mobilising our teams for projects further afield. This capability has been demonstrated through the successful completion of previous projects in locations such as Lyneham, Peterborough, Ipswich, and Swindon.
