From ground-break to handover

Construction

On a construction site, position is quality. SEC provides the control, setting-out, verification and documentation that compare what is built against what was designed — from the first benchmark to the final digital record.

Sector challenges

What goes wrong when measurement waits

Setting-out errors compound

A misplaced gridline travels through foundations, structure and finishes — found late, it is expensive.

Unknown existing conditions

Levels, structures and buried services that differ from the tender drawings surface as claims and delay.

Progress disputes

Without measured records, progress and quantities become negotiation instead of fact.

Handover without evidence

Closing a project needs as-built documentation of what was actually built.

Project lifecycle

The construction measurement cycle

Survey is not a mobilization task that ends at ground-break — it runs the length of the project.

  1. 01

    Pre-construction

    Baseline mapping and data gathering that anchor the contract to the real site.

  2. 02

    Site control

    Benchmarks and control networks established and protected for the project's life.

  3. 03

    Existing conditions

    Topographic survey and utility detection before the first excavation.

  4. 04

    Setting-out

    Gridlines, foundations, structures and services positioned from design geometry.

    • Construction Survey
    • GNSS / RTK Survey

  5. 05

    Progress verification

    Periodic capture of the works — surfaces, volumes and completion measured, not estimated.

  6. 06

    QA/QC survey

    Dimensional checks against tolerance before work is covered or built upon.

    • Engineering Survey

  7. 07

    Reality capture

    Laser scanning of built stages — a permanent measurable record of what exists.

  8. 08

    As-built & final digital records

    As-built surveys, 3D documentation and structured data handed over at closeout.

Technology approach

Measurement that keeps pace with the site

Network RTK on site

Crews position against the CORS network — shared control from network RTK corrections.

Scan-based verification

Point clouds compared against design geometry make deviations visible while they are still correctable.

Site data, organized

Survey records, progress surfaces and QA checks structured so the project record shows what was measured and when.

Field equipment

Leica Geosystems

Leica FlexLine TS07

A total station of the type used on engineering and construction survey scopes.

Leica Geosystems

Leica DNA03 Digital Level

A digital level of the type used on vertical control and repeat height scopes.

What you receive

Records the contract can stand on

  • Site control schedules and benchmark records
  • Existing-condition and pre-work surveys
  • Setting-out data and reports
  • Progress surfaces and quantity computations
  • QA/QC dimensional check reports
  • Stage point clouds and scan records
  • As-built drawings and digital handover data

Build on verified position, not assumption.

Whether you need a control network, a survey crew through execution, or as-built documentation at closeout — SEC can scope it to your programme.
