The 7-Stage Project Delivery Framework

How SMA Eng & Co eliminates guesswork, controls financial risk, and guarantees statutory structural compliance from initial concept through keys handover.

METHODICAL EXECUTION

A Rigorous Chain of Technical Accountability

QUALITY GATES & ASSURANCE

Stage-by-Stage Quality Governance

Every milestone requires formal client and engineering sign-off before subsequent site capital is mobilized.

GATE 01 โ€” PRE-DESIGN CLEARANCE Milestone: Stages 01 & 02

No architectural or structural drafting proceeds without confirmed legal land coordinates and laboratory soil bearing capacity test results. This ensures foundation designs are precisely tailored to real ground conditions.

Required Sign-off: Geotechnical Engineer & Client Scope Sign-off
GATE 02 โ€” STATUTORY & FINANCIAL APPROVAL Milestone: Stages 03, 04 & 05

Full building permit clearance through Freetown City Council (FCC) or Ministry of Works, alongside an itemized BOQ with fixed material schedules, eliminates unexpected cost escalations during construction.

Required Sign-off: SLIE Licensed Engineer Stamp & Ministry Building Permit
GATE 03 โ€” STRUCTURAL FRAME & LAB TESTING Milestone: Stage 06

Every suspended slab, cantilever beam, and column pour is sampled for 7-day and 28-day hydraulic cube crush tests. High-tensile rebar is tested before placement. Weekly drone progress videos are archived for diaspora clients.

Required Sign-off: Resident Civil Engineer Concrete Cube Crush Certificate
GATE 04 โ€” FINAL STRUCTURAL AUDIT & KEYS HANDOVER Milestone: Stage 07

Final building inspection, hydrostatic plumbing testing, electrical balance verification, and bound As-Built engineering packages are signed before issuing the Certificate of Structural Integrity.

Required Sign-off: Managing Principal Certificate of Structural Integrity & Warranty Dossier
