John Sisk & Son Ltd has worked with Tipperary Groundworks Ltd on a number of projects, dating back over 15 years. We have always found TGW to be very professional, reliable and capable of undertaking projects of significant scale and complexity to a consistently high standard and within tight programme constraints.

TGW (Tipperary Groundworks Ltd) have worked on a number of significant projects for me in recent years and have been a trusted supply chain partner to Sisk for many years.

I find their organisation to be exceptionally professional in all aspects of what they do and they strive to excel in providing a safe and high quality delivery.

Their crews are engaging, task focused and cooperative which is a culture embedded in their organisation and the hands-on engagement from both Johnny and Joe both sustains this and provides comfort to us as a client.

We carry out a lot of work in live environments where there are regularly live services and TGW are certainly an organisation that can be trusted to operate in these types of environments.

I would have absolutely no hesitation in using TGW on projects in the future and would be happy to provide reference for them if required.

I have been directly involved on the Cordis Facility in Cashel and the Pfizer Grange Castle Site where TGW have carried out large projects over the last 10 years.

On all projects they executed their works very safely in a well organised and structured manner with experienced site supervision and well-disciplined trades and operators in all areas.

All of their machinery, plant, tools and equipment was well maintained, and fit for purpose. They take a proactive approach towards Health and Safety on all their Projects.

Whilst both projects were executed in an existing operating facility TGW observed all existing site procedures and practices.

I have worked with the TGW team, led by Johnny and Joe Ryan, as our Groundsworks Contractor for the last 10 years on projects such as Vistakon, De Puy, Bio Cork 1 & 2 and now on the Springhill Stryker Project, Cork.

I have always found TGW to be a forward-thinking company with a “can do, will do” attitude and a direct approach to solving any issues that may arise on site.

TGW are a highly adaptive contract or with a modern fleet of plant well used to working within live facility’s and will hopefully continue to be a key part of a successful team here.

I would have no hesitation in recommending them.w
