Two axes: fields of operation and project cycle.
Nine complementary engineering fields, delivered across the full project cycle — from feasibility to construction supervision and capacity building.
Fields of operation
Dedicated pages describe each field, the services delivered and the Sierra Leone references that support it. Two flagship fields lead the practice: Environmental & Social Safeguards, and Feasibility, Design & Tender Support.
Environmental & Social Safeguards
The competency that makes AWSE the preferred local partner for donor-financed consortia: deep familiarity with World Bank, AfDB and IFC environmental and social frameworks.
Feasibility, Design & Tender Support
The engineering studies backbone international consortia rely on — from feasibility to tender documents, to international standards.
Hydrogeology & Borehole Drilling
Evidence-led groundwater siting, drilling, testing and equipping — from desk study to a tested production borehole.
Geomatics & UAV
LiDAR, GNSS/IMU direct georeferencing and high-resolution photogrammetry from UAV platforms, delivered as an end-to-end workflow.
Water Supply
Feasibility, design and tender support for drinking-water supply schemes serving large and small towns as well as rural communities.
Water Treatment
Conventional, advanced and membrane treatment lines, from concept to commissioning — including modular containerised systems.
Roads & Transport
Traffic engineering, feasibility studies, corridor and alignment studies, road design and traffic analysis for Sierra Leone’s strategic road network.
Bridges & Structures
Structural design, bridge and culvert sizing, cost estimates and field inspections for bridges, retaining walls and hydraulic drainage structures.
Water Resources
Resource assessment, watershed management and natural-hazard engineering — including climate-change adaptation and mitigation.
Project cycle
A single team along every step of donor-financed engineering missions.
Feasibility & Studies
Feasibility Study Reports, due-diligence and options analysis to secure funding decisions.
Engineering Design
Preliminary, final and detailed design, technical specifications, work drawings and Bills of Quantities.
Tender & Procurement Support
Preparation of international-standard tender documents and support to bid evaluation.
Construction Supervision
On-site supervision, quality assurance and reporting to clients and donors.
Technical Assistance & Capacity Building
Institutional support, technical assistance missions and training of local counterparts.
Cross-cutting competencies
Applied on every mission, regardless of the domain.
