In the realm of construction, efficient resource management stands as a cornerstone for project success. From materials and labor to equipment, the careful orchestration of these elements ensures timely completion and financial viability. However, when faced with the dynamic landscapes of coastal environments, such as those in the Niger Delta, these challenges amplify, demanding innovative solutions and strategic planning.
Understanding Resource Management in Construction
Resource management in construction includes the strategic planning and control of labor, materials, and equipment to meet project demands effectively and economically. In typical scenarios, materials alone can constitute over 50% of project costs, pointing at the critical need for streamlined management to mitigate waste and financial strain.
Coastal Dynamics
Unlike inland projects, construction in coastal regions presents a unique set of challenges rooted in environmental factors. The study published in the Journal of Offshore Structure and Technology sheds light on the specific hurdles faced in places like Bonny Island within the Niger Delta. Here, the interplay of hydrology, geomorphology, and logistical constraints complicates resource management strategies.
Challenges faced in Coastal Environments
One of the foremost challenges highlighted is the management of construction materials.
1. Labor and Equipment Challenges
Labor availability and transportation further compound the issue. Skilled workers, often sourced from urban centers like Port Harcourt, incur substantial transportation costs due to the island’s isolation.
This cost burden often limits the use of mechanical equipment, which, while essential for efficiency, is economically viable only for larger-scale projects funded by multinational entities or government bodies.
2. Uneven Ground
The study found that the soft ground on Bonny Island often requires builders to reinforce the land before construction can even begin. This adds time and cost to projects.
3. Salty Seas
Salty water can wreak havoc on building materials, causing corrosion and leading to structural failure. Builders must source fresh water for use on the site, often requiring them to drill deep boreholes.
4. Island Life
Surrounded by water, Bonny Island relies on boats and barges to transport building materials, labor, and equipment. The rough seas pose a risk of capsizing boats loaded with supplies, and barges are expensive to rent.
5. Limited Accessibility
Accessibility to construction sites presents another critical concern, particularly during the rainy season. Track roads, vital for transporting materials and equipment, can become impassable due to flooding, necessitating manual handling and potentially leading to delays and increased costs.
Even after materials arrive on the island, they may face difficulty reaching the building site. Many sites have only rudimentary tracks that become impassable during the rainy season. This can limit the use of heavy machinery and necessitate extra manual labor.
Sustainable Solutions
1. Adaptive Construction Techniques
Given the unstable subsoil conditions, builders in Bonny have adopted adaptive measures such as land reclamation through sand filling. This method not only stabilizes the ground but also prepares it for construction after a period of settlement, thereby reducing long-term structural risks.
2. Advanced Water Management
To combat the effects of saline water on construction materials, innovative water management techniques are essential. This includes the installation of freshwater boreholes to ensure a reliable source of water for concrete mixing and other construction needs. Such proactive measures help mitigate the risk of corrosion and increase the longevity of structures.
3. Enhanced Transportation Infrastructure
Addressing transportation challenges requires a multi-faceted approach. Investing in improved maritime infrastructure, such as modern barges equipped for safe material transport, can minimize the risk of accidents and ensure timely delivery of construction materials.
Additionally, exploring faster and more efficient transport options, like speed boats, can reduce overall project timelines and costs.
4. Utilization of Local Resources
Leveraging local resources, such as skilled labor and indigenous boat-building techniques, not only supports the local economy but also optimizes resource use. Training programs aimed at enhancing local skills in construction and transportation can further bolster project efficiency and reduce dependency on external resources.
5. Climate-Resilient Design Strategies
Incorporating climate-resilient design principles into construction projects can mitigate the impact of seasonal variations. This includes designing robust drainage systems and selecting materials resistant to saltwater corrosion, thereby reducing maintenance costs and enhancing project durability.

Bottom Line
Managing construction resources in coastal environments demands a nuanced approach that balances environmental sensitivity with economic feasibility. The insights from the study not only illuminate the intricate challenges faced by builders but also pave the way for sustainable practices that minimize waste and optimize resource utilization.
As coastal development continues to expand globally, these lessons serve as a crucial foundation for shaping resilient and sustainable construction practices in the face of evolving environmental landscapes.
