With the rapid expansion of renewable energy infrastructure, PV Solar projects paired with Battery Energy Storage Systems (BESS) have become essential for sustainable power solutions worldwide, including Senegal. As one of Senegal’s leading civil construction specialists, RÉGLAGE offers comprehensive expertise in the exact civil works scope required for PV Solar + BESS projects, covering road infrastructure, drainage, electrical equipment foundations, IEC and security buildings, land development, cable trenching, and perimeter security. Our team combines advanced construction techniques with an in-depth understanding of local conditions, ensuring robust, reliable infrastructure for renewable energy projects.
1. Road Works – Internal, Perimeter, and Access Roads
Road infrastructure is the backbone of any large-scale solar project, providing essential access for equipment, personnel, and maintenance. At RÉGLAGE, we design and build durable internal, perimeter, and access roads tailored for Senegal’s climate and terrain:
- Road Composition: Using high-strength, stabilized base materials and graded aggregate to ensure road longevity even with heavy vehicle loads.
- Drainage Integration: Our roadworks incorporate side drains and cross culverts to manage water flow, especially critical during Senegal’s rainy season.
- Quality Control: We ensure the load-bearing capacity of each road section meets or exceeds project requirements, with compression tests conducted at intervals to maintain consistent quality.
2. Road Crossings and Culverts
Effective water management is crucial in PV Solar sites to prevent road erosion and ensure site accessibility. RÉGLAGE builds reinforced concrete culverts and crossings designed to handle seasonal water surges:
- Hydraulic Design: Culverts are sized based on hydrological data to handle peak flows, with an emphasis on avoiding blockages or overflow.
- Reinforced Materials: Our culverts use steel-reinforced concrete with a compressive strength of 30–40 MPa, ensuring stability and durability.
- Erosion Control: Riprap and geotextiles are used around culverts to prevent erosion, maintaining the integrity of the surrounding road infrastructure.
3. Drainage Systems
In Senegal’s variable climate, drainage systems are essential to prevent water pooling and erosion. RÉGLAGE employs advanced drainage techniques to protect PV Solar project sites:
- Surface and Subsurface Drainage: We install both surface channels and subsurface drainage pipes to handle water effectively.
- Slope Grading: Site grading ensures water flows away from critical infrastructure, reducing erosion risks and extending the lifespan of structures.
- Reinforced Channels: Main channels are constructed from high-strength concrete, with riprap protection to manage water speed and prevent channel degradation.
4. Electrical Equipment Foundations – Inverter, MV Station, Street Light, CCTV Pole, Aux Transformer, etc.
Electrical equipment foundations are the core of a stable PV Solar + BESS installation, requiring precise engineering to support sensitive components. RÉGLAGE builds secure, durable foundations for various equipment:
- Load-Bearing Analysis: Foundations are designed to support the static and dynamic loads of each equipment type, with reinforced concrete foundations tailored to handle weight and vibrations.
- Thermal Insulation for Heat Control: For equipment susceptible to overheating, we include thermally insulated layers within the foundation design, preventing heat-related damage.
- Anti-Corrosion Measures: Concrete foundations incorporate corrosion inhibitors, ensuring long-term stability and protection in Senegal’s humid conditions.
5. IEC Building (Control Room)
An IEC (Industrial Equipment Control) building is central to managing and monitoring the PV Solar site. RÉGLAGE builds IEC buildings that combine security, durability, and climate resilience:
- Thermally Insulated Walls: Constructed with high R-value insulation, ensuring stable temperatures within the control room for optimal equipment performance.
- Reinforced Wall and Roof Structures: Walls are built with double-layer reinforced concrete, providing both structural support and security for critical control systems.
- Fast Construction with Prefabricated Materials: Using modular components, we reduce construction timelines without sacrificing quality or durability.
6. Perimeter Fence and Gate
Perimeter fencing is essential for site security, protecting valuable equipment and ensuring controlled access. RÉGLAGE installs durable, climate-resistant perimeter fences and gates:
- Security Fencing with Anti-Rust Coating: Galvanized steel fencing with a zinc coating provides resistance against rust, ideal for Senegal’s humid climate.
- Deep-Set Fence Posts: Fence posts are anchored with concrete footings to a depth of 1.5 meters, ensuring stability and resistance against both environmental forces and tampering.
- Tamper-Resistant Gates: Access gates are equipped with reinforced locks and security cameras for round-the-clock monitoring and control.
7. Land Development – Excavation and Filling
Land development sets the groundwork for the entire project, requiring both excavation and filling to prepare for construction:
- Precision Grading and Leveling: Using laser-guided equipment, we achieve accurate grading, ensuring a stable base for subsequent structures.
- High-Quality Fill Materials: Locally sourced fill materials are compacted to meet specific load-bearing requirements, with soil stabilization as needed to reduce settling.
- Erosion Control Measures: Temporary ground covers and silt fences prevent soil erosion during construction, preserving the surrounding environment.
8. Cable Trenching
Cable trenches must be engineered for both protection and durability to ensure the safe transmission of energy across the site. RÉGLAGE uses specialized trenching techniques to protect cables from environmental stresses:
- Waterproof Trenching Layers: Geotextiles and gravel layers are used to prevent water ingress, protecting cables from moisture and potential damage.
- Thermally Insulated Backfill: Thermal backfill materials are applied to dissipate heat, maintaining safe cable temperatures even in high-heat conditions.
- Reinforced Trenches in Rocky Terrain: Where necessary, we line trenches with concrete to prevent shifting or damage from rocky soil.
9. Security Room, Warehouses, etc.
Supporting infrastructure, such as security rooms and storage warehouses, must be both secure and weather-resistant. RÉGLAGE constructs these auxiliary buildings to high durability standards:
- Steel-Reinforced Structures: Walls and roofs are reinforced to withstand environmental wear and potential security risks.
- Climate-Controlled Interiors: Security rooms are equipped with HVAC systems to maintain a comfortable working environment for personnel.
- Efficient Storage Solutions: Warehouses are designed with flexible shelving systems to accommodate equipment and supplies securely and efficiently.
