SEC

Core discipline

Surveying & Geomatics

Land, engineering and construction surveying — from first reconnaissance to final as-built.

Service scope

  • Topographic Survey
  • Engineering Survey
  • Construction Survey
  • Pipeline Survey
  • Control Networks & Benchmarks
  • GNSS / RTK Survey

Overview

Surveying and geomatics is the discipline the rest of SEC's services build on. Our field teams establish control, capture terrain and structures, and deliver coordinated, checked geometry for design and construction use.

Work is planned around the accuracy class the project specifies, site conditions and schedule, and checks are run on a dataset before it is issued.

Applications

Topographic & engineering surveys

Site models, profiles and cross-sections for design and tender.

Construction setting-out

Staking, alignment control and verification during execution.

Pipeline & corridor surveys

Route surveys and crossing records for linear infrastructure.

As-built & quantity surveys

Verified as-built geometry and measured quantities.

SEC Capability

SEC delivers surveying as an engineering service, not a data dump.

Control before capture

Survey work starts from a designed control network tied to the project datum.

Method matched to task

GNSS, total station and levelling combined by accuracy class, not habit.

Independent QA/QC

Closed traverses, redundancy and documented checks.

Workflow & Methodology

  1. 01Scope & datum definitionRequirements, accuracy class, coordinate system and deliverable formats agreed up front.
  2. 02Control networkBenchmarks and control points established and adjusted.
  3. 03Field acquisitionDetail capture using the method mix the site demands.
  4. 04Processing & QA/QCAdjustment, verification and independent checks.
  5. 05Engineering deliverablesDrawings, models and reports issued in the formats your engineers use.
