Technical consultancy that delivers clarity, control and results.
ABD Engineering & Development LTD
ABD Engineering & Development LTD is a UK-based technical consultancy firm offering flexible, high-quality support for construction projects and engineering processes. Our approach blends field experience with strategic oversight, helping businesses, contractors, and developers navigate complex technical challenges with confidence.
About us
We are not just consultants. We are problem-solvers, collaborators, and technical partners. With a background in civil engineering, site supervision, and multidisciplinary design, we provide hands-on expertise shaped by over 15 years of combined international experience.
Our founder, Sebastian Bosoi-Diamandi, is a process engineer and technical advisor who has led projects across Romania and the UK. From large-scale construction sites to bespoke modular structures, our insight is both practical and adaptable.
What sets us apart is clarity: we believe in cutting through complexity, identifying what matters, and delivering it efficiently.
Our approach
We work with precision, but without unnecessary complexity. Each project is different — that's why we adapt our tools, rhythm, and language to fit the real needs of each client.
At ABD Engineering & Development, we focus on:
We're not afraid of real-world challenges — we're built for them.
Clarity over jargon
We communicate clearly and directly, especially when dealing with complex systems or stakeholder groups.
Responsibility, not hierarchy
We take ownership of tasks and deliverables, whether we act as consultants or direct project leads.
On-site understanding
We've built with our own hands. We know the pressure, the delays, the decisions taken in the mud, not just on paper.
Agility and transparency
We collaborate closely, share updates proactively, and adjust fast when conditions change.
Our services
We offer on-demand and project-based consultancy packages tailored to the real needs of our clients:
Technical consultancy and project support
Strategic guidance and design validation for civil engineering and mixed-use construction projects.
Site supervision and reporting
Clear, reliable presence on-site to monitor progress, check compliance, and keep stakeholders aligned.
Quality control and client representation
We protect your interests by providing independent quality assessments and acting on your behalf with third parties.
Project documentation and feasibility analysis
From technical drawings to compliance documentation, we provide support at every administrative step.
Custom modular projects
Consultancy for custom-built container homes, relocatable structures, or technical installations.
Why we exist
Because buildings need more than blueprints. Because behind every plan is a decision — and behind every decision, someone who must assume it.
We exist to make that responsibility easier to carry. To give technical decisions shape, logic, and clarity.
At ABD Engineering & Development, we're not building empires. We're building trust, one decision at a time.
