Multidisciplinary Engineering & Architectural Services

Eight integrated technical divisions covering every phase of your project lifecycle across Sierra Leoneβ€”from geotechnical boreholes and 3D architectural masterplanning to full turnkey structural delivery.

πŸ—οΈ
01

Structural Engineering & Calculations

Rigorous structural design and calculation packages for residential mansions, commercial towers, and industrial warehouses in Sierra Leone. Every structural element is engineered to withstand tropical environmental factors, seismic ground movements, and wind forces.

  • BS 8110 / Eurocode 2 reinforced concrete frame design
  • Stepped raft foundation and cantilever calculations
  • Full rebar bending schedules (BBS) and bar schedules
  • Structural engineer stamping for Council & Ministry permits

Civil Infrastructure, Roads & Stormwater

Civil engineering design and construction for highways, access roads, reinforced concrete culverts, and urban drainage networks engineered to survive Freetown's intense monsoon downpours and seasonal flash floods.

  • Asphalt and concrete paved roadway designs
  • Reinforced box culverts and trapezoidal stormwater canals
  • Hillside gabion retaining walls and slope stabilization
  • Industrial estate roads and heavy-vehicle parking logistics

Quantity Surveying & Itemized BOQ Preparation

Exhaustive, uninflated Bills of Quantities (BOQ) with itemized material rates, labor hours, and milestone cash flows in New Leones (NLe) and USD. Eliminates contractor price gouging and ensures budget predictability.

  • Itemized Bills of Quantities (BOQ) conforming to POMI/CESMM
  • Material quantity take-offs (cement, granite, sand, rebar)
  • Contractor tender review and procurement advisory
  • Interim valuation certificates for milestone bank disbursements

Geotechnical Soil Investigation & Testing

Subsurface soil testing and borehole sampling across Freetown peninsula and the provinces. Determine soil bearing capacities (kN/mΒ²), soil liquefaction risks, and groundwater tables before finalizing foundation designs.

  • Standard Penetration Tests (SPT) and core drilling
  • Soil bearing capacity analysis for raft vs. pile foundations
  • Laboratory sieve analysis, Atterberg limits, and moisture checks
  • Formal geotechnical engineering report stamped by registered engineer

Topographical Surveying & Land Demarcation

Precision geodetic RTK GNSS satellite surveying and digital total station contour surveys. Verify legal boundaries, identify terrain slope angles, and prevent costly boundary disputes before breaking ground.

  • RTK GNSS high-precision geodetic positioning
  • 3D topographical digital terrain models (DTM) and contours
  • Boundary beacon identification and dispute mitigation
  • Cut-and-fill earthwork volume calculations

Turnkey Construction Management & QA/QC

Complete on-site construction supervision and turnkey project execution. Our resident engineers control material quality, enforce rebar placement standards, test concrete slump, and provide weekly video updates.

  • Daily/weekly resident engineering site supervision
  • Batch concrete slump and 7/28-day cube crush testing
  • Contractor schedule enforcement and critical path tracking
  • Weekly 4K video walkthrough reports for diaspora owners

Forensic Engineering & Structural Retrofitting

Structural capacity audits, defect diagnoses (foundation settling, column cracking, rebar spalling), and carbon-fiber / steel reinforcement designs to safely extend, vertical-expand, or rehabilitate existing buildings.

  • Non-destructive testing (Schmidt rebound hammer & ultrasonic)
  • Structural capacity verification for vertical additions
  • Foundation underpinning and concrete crack repair designs
  • Expert technical dispute reports for properties in Sierra Leone
