Headquartered on Wilkinson Road in Freetown, SMA Eng & Co bridges the gap between imaginative architectural concepts and rigorous structural engineering execution across Sierra Leone.
Precise Reinforcement & Structural Schematics
SMA Eng & Co was founded to bring top-tier international standards of civil engineering and architectural design to Sierra Leone's rapidly expanding built environment. We recognized that clients in Freetown—both local private investors and diaspora families in the UK, USA, and Europe—faced severe hurdles with fragmented contractors, lack of structural calculations, substandard concrete aggregates, and inflated costs.
By uniting registered civil engineers, innovative architects, chartered quantity surveyors, and seasoned construction managers under one roof, we provide an unbroken chain of technical accountability: from the initial geotechnical borehole and municipal permit approval through to 3D architectural rendering and turnkey construction delivery.
To deliver professional civil engineering and architectural solutions that transform our clients' visions into structurally sound, aesthetically inspiring, and cost-effective realities—directly advancing the national development of Sierra Leone.
To be the preeminent engineering and architectural consultancy in Sierra Leone and the West African sub-region, recognized for uncompromising structural safety, innovative tropical architecture, and transparent client partnerships.
Every beam, column, and foundation is calculated with safety coefficients exceeding local code minimums.
Designs engineered for Sierra Leone's high humidity, monsoon rainfall, and solar intensity.
Milestone-based stage payments tied directly to physical engineering inspections and verified material receipts.
3D clash detection, digital structural modeling, and rebar scheduling prior to breaking ground.
Over 45% of our private residential and commercial clients reside outside Sierra Leone (UK, US, Canada, EU, and Australia). We understand the immense anxiety of building from abroad after hearing painful stories of diverted funds, substandard concrete, or abandoned projects.
Timestamped multi-angle HD walkthroughs and drone overviews of every pour and column.
Crush tests of concrete cubes at 7 and 28 days to scientifically prove MPa compressive strength.
You never pay for the next construction phase until our licensed engineer signs off on the previous one.
We verify land boundary beacons, legal surveys, and liaise with the Ministry of Lands and Freetown City Council.
Our multidisciplinary practice unites decades of civil engineering experience across residential, commercial, and national infrastructure projects in West Africa.
Led by registered professional engineers specializing in high-strength reinforced concrete frames, post-tensioned slabs, stepped hillside retaining walls, and seismic/wind load simulations compliant with British Standard BS 8110 and Eurocode 2.
Our architectural atelier crafts bespoke contemporary villas, commercial towers, and institutional complexes that respond organically to Sierra Leone's topography, leveraging cross-ventilation, brise-soleil sunshades, and native granite masonry.
Comprehensive Bill of Quantities (BOQ) preparation, material price indexing in both New Leone (NLe) and USD, contractor bidding evaluations, and stage certification to eliminate budgetary surprises and ensure high return on investment.
High-precision geodetic RTK GNSS satellite surveying, total station contour mapping, and geotechnical borehole drilling to evaluate soil bearing capacity and groundwater tables across the steep terrain of Freetown.
Whether you own land in Regent, Leicester, Goderich, or the commercial core of Freetown, our principal engineers are available for direct consultations.
