Civil and Geotechnical Engineering concerns the infrastructure on which our daily lives depend; roads, drainage systems, retaining walls and the stability of slopes and banks, on either a domestic scale or through major public works. Our role is to assess the need for such works and propose appropriate engineering solutions.

Hartigan's involvement, in both the private and public sectors starts with the assessment of the existing situation, examination of documentation, issuing recommendations for exploratory works and collecting appropriate data. This enables us to identify whether works are or will be needed and the form such works should take. We act independently or as part of a multi­disciplinary team with architects, quantity surveyors and various specialists. As a team we deliver concise drawings, specifications and contract documentation so that contractors can subm it com petitive prices. We ensure that the selected contractor successfully carries out the works, bringing them to completion on time and within budget. By following this structured design and procurement methodology, the client is provided with accurate cost forecasts at appropriate stages to facilitate budgetary planning.
