Construction & Infrastructure Services

We are not a huge monolithic company. However, you could mistake us for one going by some of the prestigious projects we have been associated with: Construction/Reconstruction, Asphalt Production and Supply, Quarry Operations for Granite Supply, to name just a few.

SUMI Global Ventures Limited scope of services encompasses geotechnical studies, road engineering, asphalt and granite production, and specialized civil works. Our expertise extends across the infrastructure, construction, and public works sectors.

CIVIL, CONSTRUCTION AND REMEDIAL WORKS

In civil, construction, and remedial works (demolition, improvement, repairs, alteration, and maintenance), SUMI Global Ventures Limited is a well-known household name across Nigeria. Our expertise covers the full spectrum of infrastructure development and rehabilitation, including but not limited to the construction of roads, highways, bridges, flyovers, drainages, culverts, erosion control structures, earthworks, and associated civil engineering projects. We also undertake building construction (residential, commercial, institutional, and industrial facilities), structural retrofitting, and large-scale remedial interventions on existing infrastructure to extend service life and restore functionality.

ROAD CONSTRUCTION

Road construction is a core business area for SUMI Global Ventures Limited, encompassing the full lifecycle of building and maintaining roadways, highways, and related infrastructure. This includes initial site surveys and geotechnical studies to assess soil stability and environmental impact, followed by detailed engineering designs that incorporate factors like traffic volume, terrain, and climate resilience — particularly important in Nigeria's diverse landscapes ranging from urban to rural areas. The process typically begins with clearing and grading the land, excavating subgrades, and laying foundational layers such as sub-base and base courses using materials like gravel or crushed stone sourced from our own quarries. Asphalt or concrete paving follows, often produced in our in-house asphalt plants, ensuring quality control and cost efficiency. Drainage systems, bridges, culverts, and safety features like guardrails and signage are integrated to prevent flooding and enhance user safety. SUMI emphasizes sustainable practices, such as using recycled materials and minimizing environmental disruption, while adhering to Nigerian standards set by bodies like the Delta State Ministry of Works and Housing. Our projects demonstrate our capability in dualization, resurfacing, and maintenance, contributing to improved transportation networks that boost economic growth and connectivity across states.

BRIDGE & FLYOVER CONSTRUCTION

Design and construction of reinforced concrete and pre-stressed bridges, flyovers, underpasses, and river crossings, including pile foundations, piers, abutments, deck slabs, and expansion joints.

DRAINAGE & FLOOD CONTROL SYSTEMS

Construction of lined and unlined drains, box culverts, retention basins, and comprehensive stormwater management systems to mitigate flooding — a critical requirement in Nigeria’s urban and coastal regions.

REMEDIAL & REHABILITATION WORKS

Failed pavement reconstruction, asphalt overlay and milling, pothole patching, bridge deck repairs, structural strengthening using carbon fibre wrapping or steel plating, seismic retrofitting, and emergency restoration of roads and bridges after natural disasters.

BUILDING & INSTITUTIONAL CONSTRUCTION

Turnkey delivery of schools, hospitals, offices, warehouses, housing estates, and industrial plants — from foundation to finishing, including mechanical, electrical, and plumbing (MEP) installations.

DEMOLITION & SITE ENABLING WORKS

Safe and controlled demolition of old structures using modern techniques (mechanical, implosion where required), debris removal, and site remediation in preparation for new developments.

CONSULTANCY & PROJECT SUPERVISION

Full consultancy services covering feasibility studies, geotechnical investigations, detailed engineering design, bill of quantities preparation, value engineering, construction supervision, and third-party quality assurance. All our civil and remedial projects are executed in strict compliance with Nigerian Standards (NIS, SON), Federal Ministry of Works specifications and international best practices. We integrate sustainable construction methods such as the use of recycled aggregates, warm-mix asphalt for lower carbon emissions, soil stabilization with cement or lime, and erosion control using vetiver grass and geo-textiles.

ASPHALT PRODUCTION

Asphalt production at SUMI Global Ventures Limited involves operating specialized plants to manufacture high-quality asphalt mixtures used primarily for road surfacing and paving. The process starts with sourcing raw materials like aggregates (gravel, sand, and stone), bitumen (a petroleum-based binder), and additives from our quarries or trusted suppliers. In the plant, aggregates are dried and heated in a rotary drum dryer to remove moisture, then mixed with hot bitumen in precise proportions to create hot-mix asphalt (HMA) or warm-mix asphalt (WMA) for lower-energy, eco-friendly options. Our facilities are equipped with advanced batch or drum-mix plants that ensure consistent quality through computerized controls monitoring temperature, mix ratios, and emissions. Quality testing labs on-site check for durability, flexibility, and resistance to weathering, aligning with international standards like ASTM and local Nigerian specifications. This vertical integration allows us to supply asphalt efficiently for our road projects and external clients, reducing costs and delays. By focusing on innovation, such as incorporating recycled asphalt pavement (RAP), we promote sustainability while supporting Nigeria's infrastructure demands, as seen in supplies for major highways like Abuja-Kaduna Road.

QUARRY AND GRANITE PRODUCTION

Quarry and granite production form a foundational supply chain for SUMI Global Ventures Limited, involving the extraction, processing, and distribution of granite aggregates essential for construction. Operations begin with geological surveys to identify viable rock deposits, followed by controlled blasting using explosives to fracture the granite bedrock. Heavy machinery like excavators, loaders, and haul trucks transport the raw material to crushing plants, where it undergoes primary, secondary, and tertiary crushing to produce various sizes of aggregates—from fine dust for asphalt mixes to larger stones for concrete and road bases. Screening and washing ensure purity by removing impurities, and stockpiling maintains inventory for just-in-time delivery. In Nigeria, where granite is abundant in regions like Enugu and Abuja, our quarries adhere to environmental regulations, including dust suppression, noise control, and land reclamation post-extraction. This business area supports our road and general construction projects by providing cost-effective, high strength materials that enhance structural integrity. Our commitment to safety and sustainability includes worker training and community engagement, ensuring operations contribute positively to local economies through job creation and resource utilization.

GENERAL CONTRACTING

General contracting at SUMI Global Ventures Limited refers to our role as the primary overseer and executor of diverse construction projects, managing everything from inception to completion on behalf of clients. This includes bidding on tenders, assembling multidisciplinary teams of architects, engineers, and subcontractors, and coordinating timelines, budgets, and resources. We handle pre-construction planning, such as feasibility studies, permitting, and risk assessments, then move into execution phases involving site preparation, structural building, and installation of mechanical, electrical, and plumbing systems. Quality assurance is maintained through regular inspections and compliance with Nigerian building codes and international standards like ISO 9001. Our expertise extends to public-sector projects, where we foster strong relationships with government agencies for seamless procurement and delivery. Examples include furnishing educational facilities or remedial works like demolitions and repairs. By leveraging our in-house asphalt and quarry resources, we minimize dependencies on external suppliers, ensuring projects are delivered on time and within budget, while prioritizing safety and innovation to drive sustainable development.

SUPPLIES

The supplies division of SUMI Global Ventures Limited focuses on the procurement, storage, and distribution of construction materials and equipment to support internal projects and external clients. This involves sourcing high-quality items like cement, steel reinforcements, tools, and safety gear from reliable vendors, often through competitive bidding to achieve cost savings. Our warehouse facilities in Lagos and other states maintain organized inventories using modern systems for tracking and just-in-time delivery, reducing waste and storage costs. We emphasize ethical sourcing, ensuring materials meet environmental and quality standards, and provide value-added services like custom mixing or bulk packaging. In Nigeria's dynamic market, this area helps mitigate supply chain disruptions caused by logistics challenges or import delays. By integrating with our quarry and asphalt production, we offer comprehensive packages, such as ready-to-use aggregates or asphalt mixes, fostering long-term partnerships with contractors and government bodies.
