At HLDS Co., Ltd we specialise in delivering clear, standards-compliant drafting and BIM documentation that supports structural, civil, and hydraulic engineering teams throughout all project stages.
Our focus is on accuracy, constructability, and attention to detail, ensuring that every drawing aligns seamlessly with engineering intent. With experience across a wide range of projects, we provide efficient documentation solutions that help streamline coordination, reduce rework, and support successful project delivery.
OUR SERVICES INCLUDE:
STRUCTURAL DRAFTING
2D drafting using AutoCAD and 3D drafting using Revit or a hybrid approach when required. Our workflows are tailored to align with your drafting standards and markup systems.
CIVIL DRAFTING
Road grading, drainage design, long sections, and natural ground level (NGL) modelling using AutoCAD or Civil 3D.
HYDRAULICS DRAFTING & BIM MODELLING
Hydraulics BIM modelling and documentation to LOD 350, including sewer drainage, stormwater systems, hot and cold-water supply, and fire services. Our models and drawings are developed to support coordinated design, authority submissions, and construction-stage delivery.
BIM COORDINATION
3D modelling, clash detection, and drawing extractions to support coordination, constructability, and design accuracy across multidisciplinary teams.
Through years of working across diverse projects and engineering teams, we’ve developed a responsive, detail-focused system that adapts quickly to client requirements. Every drawing set undergoes systematic internal checks before reaching your engineers, ensuring clarity, consistency, and readiness for review.
