Design and engineering
We prepare design documentation covering every required stage — from pre-design work to the working documentation the building is constructed from.
A good design is the foundation of successful construction: it defines the building's architecture, structural solutions, schedule and budget. Sian Group's design service covers every stage required.
Design stages
The main design stages set out in the regulations are:
- pre-design work;
- design project (Stage P);
- working documentation (Stage RD).
For standard buildings and facilities of certain responsibility classes, the stages can be combined. This is known as single-stage design.
Pre-design stage
Sketch design. The architectural and urban-planning part is prepared: architectural drawings and a 3D model. The sketch design forms the basis for the structural solutions. It is based on the design brief and the available source data and is approved by the city's architectural services.
Site plan and land demarcation project. This defines the layout of existing and planned structures on the allocated plot.
Stage P (design project)
The project sections are developed for submission to state expert review and to the bodies that permit construction, repair and reconstruction. The work follows the applicable government regulations and technical and building standards. At this stage we also prepare the cost estimate — the calculation of construction, work and material costs.
Stage RD (working documentation)
The working documentation needed to implement the adopted structural and technical solutions is developed. It is used to supply the site with equipment, components and materials and to carry out construction and installation work.
At every design stage, we agree the solutions with the client so that the final documentation fully matches your requirements and budget.
Why Sian Group?
Sian Group does not only design: we build and supply projects with building materials from our own vast warehouse. That is why we design so that the project is easy and economical to build — using materials that are in stock and available at wholesale prices. Contact us to discuss your project, and we will suggest the most suitable design format.
