Quality survey solutions and consultancy

Paul Corrigan & Associates (PCA) Ltd. Geo-Surveyors is a multidisciplinary practice with 40 years’ experiences in all aspects of land and measured building survey. We pride ourselves on providing tailored survey solutions to all our clients, with an emphasis on continuous product support and detailed advice.

As one of Ireland’s leading Geo-Survey Consultancies, we aim at all times to achieve the highest standards in survey practice and customer service, embracing the very latest in survey technologies and methods.

Why not have a look at some of our work by visiting us on social media, or by dropping by our YouTube channel. You can find the links to all at the bottom of the page.

Whatever your survey needs, PCA has the solution.


Each project can have many possible survey solutions depending on the client’s requirements and budgets. Some clients prefer a survey to be built up in modular format, others may require more or less in terms of accuracies and extents.


When considering a survey specification, think PCA: we are happy to advise. Every job has its own demands – its own unique set of requirements of accuracy, content and presentation.


Disputes can arise at any time, and property boundaries and land use are key flashpoints. At PCA, we have the experience and expertise necessary to mediate disputes and enable all parties come to a rational, common-sense solution. We are Chartered Arbitrators and also offer an expert witness service for litigation and arbitration.


In this constantly changing world, it is more and more important to keep accurate records of our natural and built environment. At PCA, we recognise that our clients’ needs often extend beyond traditional surveys.
