Telecommunications Consulting & Design

We specialise in infrastructure design, engineering consulting, and hands-on project implementation support. Our team also conducts structural inspections and condition assessments, including advanced UAV and drone inspections for safer, faster insights.

  • Technical site surveys, design and drawings
  • Tower structural modelling and analysis (Rooftop, greenfields)
  • Fabricator compliance audits
  • Infrastructure fabrication compliance and inspections
  • Site release inspections
  • Infrastructure conditional assessments
  • Infrastructure legal compliance inspections
  • Infrastructure audits and upgrades
  • Asset verification and management support
  • Project management and deployment support
  • Line-of-sight (LOS) and RF path studies
  • Civil works design
  • Drawings from the concept, design, to manufacturing
  • As-Built drawings
  • Structural upgrader designs and retrofits
  • Integrated power system design and hybrid solutions
  • UAV-based inspections for difficult accessible areas
  • Compliance and Safety Audits
  • Infrastructure maintenance and repairs

Site Mapping & As Built Reconstruction

In many cases, infrastructure owners no longer have access to the original construction documentation (“As‑Built” drawings). Without accurate baseline data, engineers are forced to make assumptions about tower dimensions, steel grades, foundation sizes, and loading capacity. These assumptions often lead to overly conservative designs, unnecessary strengthening works, or missed opportunities for additional loading.

Site mapping resolves this by generating a precise, modern as‑Built record of the entire structure and its foundations.

Purpose of Site Mapping

  • Replace assumptions with verified measurements.
  • Enable accurate structural modelling and engineering calculations.
  • Identify unused structural capacity.
  • Support compliance, upgrades, and co‑location planning.
  • Reduce risk and cost associated with uncertainty.
1. Tower Structural Measurements

Surveyors perform a full measure‑up of the tower, capturing:

  • Steel member dimensions (uprights, diagonals, horizontals, braces)
  • Steel quality, thickness, and condition
  • Weld locations and characteristics.
  • Connection details and bolt specifications
  • Tower geometry, alignment, and plumbness
2. Foundation and Substructure Assessment

Accurate foundation data is essential for load‑capacity calculations. The assessment includes:

  • Verification of foundation size, depth, and configuration
  • Measurement of holding‑down bolt patterns and embedment
  • Inspection of anchor blocks for guyed towers
  • Assessment of concrete condition, cracking, and environmental wear
3. Integration of Historical Information

Where available, surveyors incorporate:

  • Legacy site plans
  • Old As‑Built drawings.
  • Engineering reports
  • Construction notes or photographic records

These references help validate measurements and fill in gaps where direct inspection is limited.

4. Creation of a New As‑Built Record

Using precision instruments and modern surveying techniques, a complete as‑Built package is produced, covering:

  • Tower geometry and member schedule
  • Foundation layout and dimensions
  • Anchor points, guy systems, and holding‑down arrangements.
  • Site layout, equipment positions, and access routes

The output is a detailed engineering‑grade report suitable for structural modelling, capacity analysis, and regulatory submissions.

Desired outcomes

Accurate site mapping transforms unknowns into certainties. With verified structural data:

    • Engineers can model the tower with confidence.
    • Load‑capacity calculations become more precise.
    • Additional antenna loading is often unlocked.
    • Strengthening works can be avoided or optimized.
    • Owners gain a reliable baseline for future upgrades.

In many cases, the process reveals that the tower can safely support more equipment than previously assumed — directly increasing revenue potential and reducing unnecessary capital expenditure.
