Construction Drawings
Creating precise construction drawings is an essential foundation for delivering successful building projects on time and within budget.
From commercial facade systems and curtain walling to structural steelwork, bracketry, and bespoke fabrication, our construction drawings, contract drawings, and fabrication drawings provide the detailed technical information needed for accurate manufacture, fabrication, and installation, minimising errors, reducing costly rework, and ensuring full compliance.
Whatever the scale or technical complexity of your project, our experienced team works closely with contractors, fabricators, architects, and clients to understand project requirements, site conditions, and performance goals, guiding you seamlessly from survey data through to final fabrication-ready documentation.
Achieve precision in every detail.
Our Construction Drawings Service
Our construction drawings packages provide everything required to support accurate fabrication, installation, and project execution, including:
- Initial site visit, survey, and consultation to assess existing conditions, constraints, and requirements
- Detailed measurements and as-built surveys of the building/structure
- Technical design concepts and visualisations showing proposed solutions and interfaces
- Comprehensive construction drawings;including plans, elevations, sections, and enlarged details
- Contract drawings package for tendering, contractor pricing, and statutory compliance
- Fabrication drawings for specialist components (bracketry, curtain walling, rainscreen cladding, steelwork, etc.)
- Full material, fixing, and performance specifications
- Support with building regulations, structural calculations, and compliance documentation
- Optional coordination and project liaison services to ensure smooth handover to fabricators/installers
From straightforward 2D detailing to complex 3D-coordinated facade systems, our technical design team manages the entire documentation process. Using cutting-edge CAD and modelling software, we deliver clear, accurate, and fully coordinated drawings for a seamless, stress-free fabrication and construction experience.

Construction Drawings FAQs
Construction drawings are detailed technical drawings that provide contractors, fabricators, and installers with all the information needed to execute the works accurately. They include plans, sections, elevations, details, specifications, and dimensions, bridging the gap between design intent and on-site/building reality.
Costs vary depending on project complexity, size, level of detail required, and whether fabrication drawings are included. Simple packages can start from a few thousand pounds, while comprehensive sets for large facades or multi-system projects are higher. We provide clear, fixed-price proposals after an initial review of your requirements.
Across the UK, fees for professional construction drawings and fabrication drawings packages range widely depending on scope. PDK prepares precise, tailored documentation with full cost visibility upfront so you know exactly what to expect.
The main factors are project scale, complexity (e.g., curtain walling, bespoke bracketry, structural interfaces), number of details required, and whether structural calculations or wind-loading assessments are needed. We always aim to balance technical rigour with commercial efficiency.
We specialise in commercial facade projects including curtain walling, rainscreen cladding, windows/doors, bracketry, and steel support systems from leading manufacturers (Kawneer, Schüco, Reynaers, Senior, Sapa, and more). We also produce fabrication drawings, contract drawings, and technical detailing for contractors and fabricators across various sectors.
Yes, while construction drawings show the overall design intent, fabrication drawings provide the precise, component-level information (dimensions, tolerances, fixings, welding details) that fabricators require to manufacture accurately off-site. We produce both as needed for seamless coordination.
Many elements must comply with building regulations, British/European standards, and manufacturer specifications. We include all necessary details for compliance and can support structural calculations, wind load assessments, and liaison with building control where required.
Yes. We have extensive experience creating detailed fabrication drawings and installation details for curtain walling, rainscreen cladding, bracketry, and other facade components, ensuring compatibility with leading UK systems and accurate on-site assembly.
Extremely accurate, even small discrepancies can lead to costly delays or remedial work. Our drawings incorporate site-surveyed dimensions, precise tolerances, and full coordination with adjacent construction, giving fabricators and installers complete confidence.
