Whatever your survey needs, PCA has the solution.

CONSULTANCY

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.

SPECIFICATION

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.

MEDIATION

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.

CURATION

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.
