Multi-disciplinary engineering expertise, in one team.

Most infrastructure projects fail on coordination, not technical difficulty. DACI runs electrical, water, gas, earthing, civil, drainage and renewables design under one roof, so nothing gets lost between disciplines or between consultants.

Regular updates, proactive planning, and transparent coordination help eliminate uncertainty throughout the project.

Everything you need to get started

 From utility coordination to adoption, here are the answers we're most often asked before a project starts.

What services does DACI provide?

DACI delivers engineering design across electrical (LV, HV and EHV), water, gas, earthing, civil, drainage and flood risk, and renewables, plus supporting consultancy such as feasibility studies, cable route legals and tendering support. All disciplines sit within one in-house team, from early design through to adoption or connection.

Which types of projects do you work on?

Housebuilding, industrial, commercial and mixed-use developments, plus framework and direct-appointment work for water, energy and renewables clients. Project scale ranges from single-plot connections to multi-phase infrastructure programmes.

Why should I choose DACI instead of managing multiple consultants?

Because coordination between separate consultants is usually where programmes lose time, not the engineering itself. One multi-disciplinary team means one design intent, one point of accountability, and no version of the design that only exists in someone else's inbox.

At what stage should I involve DACI?

As early as feasibility, ideally before the design strategy is fixed. Early involvement is where we catch the constraints that are expensive to fix later; but we also pick up projects mid-programme where coordination has broken down and needs resetting.

What are the working arrangements?

Direct appointment, framework call-off, or as an embedded extension of your existing project team, whichever fits how you already run projects. We scale involvement up or down as the programme demands it.

Can DACI work alongside our existing project team?

Yes. Most of our work runs inside a client's existing project team. We learn how the team already operates before proposing changes, and we coordinate with developers, EPCs, contractors, DNOs and adopting authorities so the design sits in one place with one point of accountability.

Let's Engineer Your Next Project.

Whether you're planning a new development, upgrading existing infrastructure, or need expert engineering support, our team is ready to help you move your project forward with confidence.
