Expert Reinforced Concrete Detailing Services
Established in 2009 by Stephen O'Hara and Michael Dunbar, R C D S Ni has grown from a two-person partnership to a respected provider of reinforced concrete detailing solutions across the UK and Ireland. Our team of senior structural detailers and BIM modellers specialise in delivering precision 3D BIM models and 2D drawings using industry-leading software including Tekla Structures and CADS RC. With offices in Magherafelt, Lisburn, and Derry, we combine technical expertise with practical experience to support precast and in-situ concrete projects of all scales. Our services encompass preliminary models, production drawings, reinforcement schedules, and comprehensive project management, ensuring seamless integration from design through to construction.We maintain rigorous quality control through fully traced documentation and electronic files compatible with bar bending processes. Our commitment to innovation is demonstrated through cloud-based collaboration tools and continuous investment in staff development. Having worked on prestigious projects including stadium developments and major public sector contracts, we provide scalable solutions tailored to client needs while reducing overhead costs through outsourced drawing office capabilities. Our mission remains focused on delivering class-leading detailing solutions that meet evolving industry standards and client expectations.

Services
3D BIM Models
We create detailed 3D BIM models for construction projects using Tekla Structures software. These models support accurate planning, clash detection, and material quantification throughout the project lifecycle. Our models integrate seamlessly with manufacturing processes for improved efficiency.
Reinforcement Schedules
Our comprehensive reinforcement schedules provide precise bar bending details and tonnage calculations. These documents ensure accurate production and on-site implementation while maintaining full traceability through project phases.
Project Management
Senior staff provide continuous project management from initial design to construction completion. We coordinate with site teams to resolve technical challenges and maintain project timelines while ensuring documentation accuracy.
Production Drawings
We produce detailed production drawings for precast concrete manufacturing. These documents include all necessary information for factory staff to maintain quality control and production efficiency during fabrication processes.
General Arrangement Drawings
Our 2D general arrangement drawings derived from 3D models facilitate design approvals at all project stages. These documents maintain dimensional accuracy and compliance with industry standards for structural verification.
