Civil Engineering

Ghana's intense rainy seasons require robust drainage solutions to prevent flooding and erosion. Our drainage engineering approach includes comprehensive hydrological analysis using local rainfall data, proper sizing of drainage channels and culverts for peak flow conditions, integration of sustainable urban drainage systems (SUDS) where appropriate, erosion control measures and slope stabilization, consideration of future development and climate change impacts, and coordination with municipal drainage networks. We design systems using rigorous calculations and modeling to ensure adequate capacity. For existing properties experiencing flooding issues, we conduct drainage assessments and design remedial solutions. Our designs protect infrastructure investments while managing stormwater sustainably.

Road construction timelines depend on project scope, length, and complexity. For typical projects: Design and engineering take 1-3 months, permitting and right-of-way acquisition require 2-6 months (often the longest phase), and construction spans 3-12 months per kilometer depending on road classification and site conditions. A 5-kilometer urban road project typically requires 12-18 months from design initiation to completion, while rural access roads may proceed faster. Factors affecting timeline include weather (rainy season can delay earthworks), utility relocations, community engagement requirements, and material availability. Svelto's project management ensures efficient sequencing of activities to minimize delays while maintaining quality standards.

Yes, geotechnical services are integral to our civil engineering practice. We conduct comprehensive soil investigations including test boring and sampling, laboratory testing (soil classification, bearing capacity, compaction properties), groundwater assessments, foundation design recommendations, pavement subgrade evaluation, and slope stability analysis. Proper geotechnical investigation prevents costly foundation failures, pavement distress, and structural issues. For road projects, we evaluate subgrade conditions to optimize pavement design. For building sites, we determine appropriate foundation types and depths. Our geotechnical reports provide clear, actionable recommendations that inform design decisions and construction methods, reducing risk and ensuring long-term performance.

Yes, infrastructure rehabilitation is a key service area. Many of Ghana's roads and drainage systems require rehabilitation due to age, increased traffic loads, or inadequate initial design. Our rehabilitation services include condition assessments using visual surveys and testing, failure analysis to identify root causes, design of repair and strengthening solutions, pavement overlay and reconstruction, drainage system upgrades, and bridge repair and strengthening. Rehabilitation often proves more cost-effective than complete reconstruction while extending infrastructure life by 15-20 years. We develop rehabilitation strategies that address underlying issues, not just symptoms, ensuring durable repairs. Whether rehabilitating urban streets, highways, or drainage systems, we restore functionality to international standards.
