Our Mission

Fitzsimons Doyle & Associates have completed over 3000 projects since the firm was founded in 1979 ranging from very small renovation/refurbishment works, to projects in excess of €80m construction cost.

We have worked as Consulting Structural Engineers as part of a traditional design team, as project leaders/managers and within large institutions as part of their in-house design/building offices.

Our belief in building strong working relationships with our clients has resulted in many repeat commissions in both Public Institutions and Private companies for over thirty years, where Fitzsimons Doyle & Associates have been working closely with in house technical departments and design teams.

Establishing good communications and developing a complete understanding of the client’s needs have achieved these lasting relationships.
