How we help

Measured accurately.
Designed thoughtfully.

We use cutting-edge point-cloud scanning to capture detailed building measurements and produce extremely accurate existing-condition drawings. This provides a dependable foundation for your design, helping us understand the geometry and relationships within the existing building.

Detailed digital capture of the building to support accurate existing plans, elevations and sections.

Technical drawings and construction details for building control consideration, coordinated with structural and other specialist designs where required.

04

Building Regulations Principal Designer

We act as Building Regulations Principal Designer, planning, managing and monitoring design work and coordinating the designers so the design meets the applicable Building Regulations.

The Qualis approach

The detail behind a better project.

Accurate surveys, clear design information and early coordination help the project team work from a consistent set of drawings. We can also bring together party wall advice, CDM services and project delivery support within an agreed appointment.

Building Regulations Principal Designer

Design coordination with a clear responsibility.

We coordinate the design team's work in relation to compliance with the Building Regulations and liaise with the client and principal contractor as the design develops.

The Building Regulations Principal Designer and CDM Principal Designer are separate roles. The former concerns building regulations compliance; the latter concerns health and safety during the pre-construction phase. We agree the required appointments and scope at the outset.

Your questions.

What does point-cloud scanning add?

The scanner captures a detailed digital record of visible building surfaces. We use that measured information to prepare highly accurate drawings and understand the existing building before developing proposals.

Do you provide building regulations drawings?

Yes. We prepare building regulations designs and technical details, coordinating relevant information from the wider design team.

Can you act as Building Regulations Principal Designer?

Yes. We provide this service within an agreed appointment appropriate to the project and design scope.

Do you use measured surveys?

Where appropriate, we use point-cloud scanning to record the existing building and support the preparation of drawings.

Are structural calculations included?

Structural engineering is a separate discipline. We confirm whether coordination is included and identify any separate engineer appointment.

Can you work from existing planning drawings?

Yes, subject to checking their suitability and the agreed scope. Send us the drawings and any decision notices for review.
