Overview

Project Overview

The Lekki Free Zone — a 16,000-hectare industrial and logistics hub on Lagos' eastern corridor — is home to Nigeria's flagship Lekki Deep-Sea Port, major manufacturing facilities, and international industrial tenants. Envostructs was engaged by the Lekki Free Zone Development Company (LFZDC) to design and construct two key internal road corridors: Road N5 and Road E6A. These roads form part of the zone's permanent internal network, serving industrial plants, warehouses, and logistics operations within the free trade zone. The roads were designed for extreme heavy-vehicle loadings — accommodating port vehicles, oversized industrial equipment, and the demanding operational environment of an active port and manufacturing estate within the Lekki peninsula's coastal reclaimed terrain.

Challenges & Solutions

Challenges

Designing for extreme heavy-vehicle loadings — port vehicles, factory trucks, and oversized industrial equipment
Construction on coastal reclaimed land — managing weak subgrade conditions on the Lekki peninsula's sandy/alluvial soils
Coordinating construction around active industrial operations without disrupting the zone's ongoing development
Drainage design adequate for Lagos' intense coastal rainfall on low-lying reclaimed land

Our Solutions

Heavy-duty pavement design with deep sub-base and base course layers for port and industrial vehicle loads
Ground improvement works — compaction and sub-base strengthening to stabilize the reclaimed coastal land subgrade
Phased construction plan separating works zones from live industrial and logistics operations throughout
Comprehensive storm drainage network designed for 1-in-25-year storm event on the coastal low-lying terrain
