From Digital Vision
To Real-World Precision

Architecture Systems

We design and build.

  1. 01

    Architecture

    Competition, preliminary design, building project and construction documents for new builds, conversions and existing stock.

  2. 02

    Site management

    Tendering, contracting, schedule, cost and quality. Target and actual continuously checked against the scan.

  3. 03

    LiDAR surveying

    Terrestrial laser scanning of buildings, interiors and terrain — registered and georeferenced.

  4. 04

    Concept studies

    Feasibility, massing and options as a basis for decisions, before a single franc goes into planning.

  5. 05

    Specialist planning, all trades

    HVAC and plumbing, electrical and building physics from one source — coordinated in the same model.

From capture to handover

  1. Capture

    LiDAR survey of building, interiors and terrain — registered and georeferenced.

    Point cloud

  2. Studies

    Feasibility, massing and options directly on the scan.

    Study

  3. Design

    Preliminary design, building project and permit on the measured existing building.

    Building project

  4. Tendering

    Quantities from the model, tendering and contracting on a solid basis.

    Bill of quantities

  5. Construction

    Construction documents and site management, target and actual continuously checked against the scan.

    Target/actual

  6. Handover

    Final scan and as-built model for operation and future conversions.

    As-built
Project types
  • 01

    Conversion & renovation

    Residential and commercial buildings in existing stock, from partial conversions to full renovations.

  • 02

    Extension & densification

    More floor area on existing plots — massing, structure and zoning clarified early.

  • 03

    New build

    Housing, commercial and mixed use, from competition to handover.

  • 04

    Heritage

    Listed buildings precisely documented and carefully developed further.

  • 05

    Interiors

    Offices, practices and shops, planned in the measured space rather than in old drawings.

  • 06

    Sites & landscape

    Site development and outdoor space on terrain from the drone scan.

Scanning

Precision beyond the point.

Our own scanners on the ground and in the air, processed in our own app Unary Capture.

How we work together
  1. 01

    Work with our tools

    Pipelines and plugins in your own environment. Your team works independently — we provide onboarding, training and updates.

  2. 02

    Team up on complex projects

    Our team supports yours with scan-to-BIM, automation and integration — per project, with our tools.

  3. 03

    Project split

    Preliminary study, preliminary design, base plans or just site management: we support you in every phase — exactly where you need us.

Techqon Systems · Pipeline

From scan to model.
In your office.

We build the pipeline, you keep the design. Every stage runs in your environment and ends in your program — automated, versioned and traceable.

Stage 01

Import

Scan data from all common scanners, photos and existing drawings are taken over and checked for completeness.

Output
E57LASPTX
Techqon Systems · Plugins

We work inside
your tools.
