Project Overview: CAD Drafting for Ireland Residential Development
Optimar Precon supported a €40 million residential development in Dublin, Ireland by delivering fast, accurate CAD drafting services for a new 200-unit apartment complex across five buildings. The development was designed to meet NZEB (Nearly Zero Energy Building) standards and had to be delivered within an 18-month schedule.
We were selected to handle 2D architectural and structural drafting using AutoCAD and BIM tools. With over 22 years of experience in CAD documentation, our team accelerated the design phase while ensuring compliance with energy-efficiency regulations and coordination with MEP systems.
Challenge: Inconsistent Drawings and Design Delays
Early design reviews uncovered significant inconsistencies in CAD files. Misaligned layouts—like window positions conflicting with structural columns—posed a €1.5 million rework risk and threatened a two-month delay.
The client also needed detailed, NZEB-compliant documentation for insulation and ventilation systems to secure planning approval. Manual drafting methods weren’t fast or precise enough to meet the schedule. The project team needed standardized drawings, error-free documentation, and MEP-ready outputs.
Our Solution: Accurate and Coordinated CAD Drafting
Optimar Precon delivered a customized CAD drafting solution focused on speed, compliance, and precision:
- Drawing Standardization
Consolidated and updated over 300 architectural and structural drawings in AutoCAD, ensuring full consistency across all disciplines. - Structural Drafting Accuracy
Produced detailed plans for beams, slabs, and columns with 1mm-level precision, eliminating alignment errors. - NZEB-Compliant Detailing
Integrated layouts for high-performance insulation, air handling, and ventilation directly into the CAD files to support energy code compliance. - BIM Integration
Converted key 2D CAD plans into Revit models, enabling smooth coordination with MEP engineers and clash detection workflows. - Quality Control & Collaboration
Conducted multi-stage reviews and cross-checked with site survey data. Shared all files via a cloud-based platform to support real-time feedback from Dublin-based teams.
Shop drawings were also provided for use during construction, minimizing miscommunication and rework on site.
Results: Efficient, Compliant, and Error-Free Drafting
Our CAD drafting services delivered measurable results:
- 30% Faster Delivery – Delivered CAD packages six weeks ahead of schedule, accelerating the design phase.
- 98% Error Reduction – Virtually eliminated drafting errors, avoiding an estimated €1.2 million in rework costs.
- Full NZEB Compliance – Achieved approval on the first submission—zero revisions required.
- Material Cost Efficiency – Helped reduce waste by 10% through accurate quantity representation in drawings.
- Reliable Delivery – Maintained a 100% on-time record, improving confidence and communication across project teams.
The client praised our ability to deliver high-quality CAD outputs under tight deadlines, ensuring smooth project execution.
