The firm delivers integrated civil, structural, transport, and environmental engineering design alongside project management and PSDP/health and safety advisory services. Its end-client base spans Irish public-sector bodies (Fingal, South Dublin, and Galway City county councils, Transport Infrastructure Ireland, the Health Service Executive, and IDA Ireland) and private-sector clients in real estate, pharmaceutical, technology, and infrastructure - including Microsoft, Google, Pfizer, Takeda, Dexcom, Aryzta, Henderson Park, and Horse Racing Ireland. The firm holds ISO 9001, ISO 14001, ISO 45001, and ISO 19650-2 certifications and is an Engineers Ireland CPD Accredited Employer (re-accredited 2026-2029).

CSEA operates as a professional services consultancy, generating revenue via competitive tendering for public-sector projects and direct appointments for private-sector work, with quote-based project-specific pricing. It employs 115+ staff, including 25+ Chartered Engineers, across two Irish offices (Dun Laoghaire headquarters and Balbriggan branch). Core technical capabilities are built around Building Information Modelling (Autodesk Revit, Civil 3D, Navisworks), BIM Level 2 information management under ISO 19650-2, and project delivery using PRINCE2 and PMBOK methodologies. CSEA reports over 5,000 completed projects across 70+ years, with notable depth in data centre delivery (638,500 m² and 1,600+ MW across EMEA) and power infrastructure (14 completed HV substations and 52.5 km of underground grid connections).

In February 2025, CSEA became part of Typsa Group, an international engineering organisation with over 3,800 professionals operating in transportation, buildings, water, and environment sectors. The affiliation extends CSEA's effective reach into the UK, Denmark, Germany, Greece, Norway, Spain, and Sweden, while the firm retains its Irish brand and operating autonomy. The combined platform positions CSEA on cumulative data centre project value exceeding €1.5 billion across these EMEA markets.
