Frequently Asked Questions — Certified Professionals in Kenya
The Engineers Board of Kenya (EBK) and National Construction Authority (NCA) certifications ensure that professionals meet the legal and technical standards required for construction projects in Kenya. County councils and government agencies require designs and supervision reports signed by EBK-registered engineers, NCA-registered contractors, and BORAQS-registered quantity surveyors. Working with certified professionals from Cadreatech protects you from project delays, rejections during approval, and potential legal liability.
Most building projects in Kenya require development permission and building plan approval from your county government. Depending on your project location and scope, you may also need NEMA environmental impact assessment approval, Water Resources Authority (WRA) permits for boreholes or wastewater discharge, fire safety approval, and occupation certificates. Cadreatech guides clients through the entire county approval process, preparing compliant documentation and liaising with relevant authorities.
Approval timelines vary by county but typically range from 60 to 90 days for straightforward residential and commercial projects. Complex developments requiring NEMA approval or special permits may take 4 to 6 months. Cadreatech expedites the process by submitting complete, accurate documentation and maintaining regular follow-up with county planning departments to avoid unnecessary delays.
High-rise buildings in Kenya are subject to more stringent structural engineering requirements than standard residential or commercial developments. Buildings exceeding four storeys typically require a detailed geotechnical investigation to inform foundation design, wind load analysis, and seismic consideration in line with Eurocode and Kenya Building Code provisions. County governments and the National Building Inspectorate may require peer review of structural designs for tall buildings. Cadreatech’s structural engineers have experience delivering certified high-rise designs using advanced structural analysis software, ensuring your development meets all safety, regulatory, and performance requirements from foundation to roof.
While not always legally mandatory, engaging a BORAQS-registered quantity surveyor is highly recommended for projects with budgets above KES 1 million. Quantity surveyors prepare accurate Bills of Quantities (BoQs), conduct cost estimates, manage project budgets, and handle contractor payments. Cadreatech’s certified quantity surveyors help clients avoid cost overruns, ensure value for money, and maintain financial control throughout the construction process.
Yes. Cadreatech serves clients across all 47 counties in Kenya. Our team has extensive experience navigating approval processes in Nairobi, Mombasa, Kisumu, Nakuru, Eldoret, Machakos, Kiambu, and other county governments. We understand regional variations in planning requirements and maintain professional relationships with county officials nationwide to facilitate smooth project approvals wherever you build.
Standard requirements include: land title deed or allotment letter, survey plan or site plan, architectural drawings (floor plans, elevations, sections), structural drawings signed by an EBK engineer, plumbing and drainage plans, electrical layouts, storm water management plan, and completed county application forms. Cadreatech prepares all technical documents to county standards and compiles complete submission packages that meet approval requirements on first submission.
Projects classified under NEMA’s Second Schedule — such as large commercial developments, industries, fuel stations, or projects near sensitive environments — require an Environmental Impact Assessment (EIA) or Environmental Audit (EA) before construction begins. The NEMA approval process typically adds 2 to 4 months to your timeline. Cadreatech’s environmental consultants conduct the necessary assessments, prepare EIA reports, and facilitate public participation to secure NEMA licenses efficiently.
A BORAQS-registered architect is a legally qualified professional authorized to design buildings, prepare architectural drawings, and sign plans for county approval in Kenya. Architects translate your brief into functional, code-compliant building designs — covering space planning, aesthetics, material selection, and coordination with structural and MEP engineers. For most permanent buildings in Kenya, county approval requires architectural drawings signed by a BORAQS-registered architect. Beyond compliance, a skilled architect adds significant value by optimizing your space, managing natural light and ventilation, and ensuring your building is both livable and cost-efficient to construct. Cadreatech’s BORAQS-registered architects work closely with our structural and civil engineering teams to deliver fully integrated, approval-ready designs.
A structural engineer is required on any project involving a permanent load-bearing structure — residential, commercial, or industrial. Their role is to design and certify the structural system that keeps your building safe: foundations, columns, beams, slabs, retaining walls, and roofing structures. In Kenya, all structural drawings submitted for county approval must be signed and stamped by an EBK-registered structural engineer. Beyond design, structural engineers conduct site inspections during construction, certify completed works at each stage, and issue the structural completion reports required before an occupation certificate is issued. Cadreatech’s EBK-registered structural engineers use advanced analysis software including ProtaStructure and Axis FEM to deliver precise, code-compliant designs tailored to Kenyan soil conditions, load requirements, and construction methods.
Professional Engineering Services in Kenya — Key Terms & Standards
Understanding Kenya’s regulatory framework helps project owners make informed decisions and avoid costly mistakes. Below are the essential concepts governing certified engineering practice in Kenya.
Engineers Board of Kenya (EBK) Registration
The statutory body established under the Engineers Act (Cap 530) to regulate the engineering profession in Kenya. EBK registration is mandatory for all practicing engineers, who receive an annually renewed practicing license authorizing them to sign engineering drawings, certificates, and reports for regulatory submission. Cadreatech maintains full EBK registration across all engineering departments.
National Construction Authority (NCA) Compliance
The NCA Act, 2011 regulates Kenya’s construction industry, registering contractors across nine categories based on financial capacity and technical capability. All construction projects must be registered with NCA, and contractors must display valid certificates on site. Cadreatech works exclusively with NCA-compliant contractors and maintains NCA registration for our project management services.
BORAQS Registration
The Board of Registration of Architects and Quantity Surveyors (BORAQS) registers and regulates architects and quantity surveyors under the Architects and Quantity Surveyors Act (Cap 525). BORAQS-certified professionals are authorized to prepare Bills of Quantities, cost estimates, and contract documents, and to sign architectural drawings for building approval. Cadreatech’s team includes BORAQS-certified professionals across both disciplines.
County Development Control & Approval
Following devolution under Kenya’s 2010 Constitution, county governments have authority over physical planning, building control, and development approval. Each of Kenya’s 47 counties operates a physical planning department that reviews building plans, enforces zoning regulations, and issues development permissions. Cadreatech’s familiarity with county-specific requirements ensures timely approval without costly resubmissions.
NEMA Licensing
NEMA enforces the Environmental Management and Coordination Act (EMCA, 1999), requiring environmental assessment for projects with potential environmental impacts. Depending on project type and scale, you may need an Environmental Impact Assessment (EIA), Environmental Audit (EA), or simplified Environmental Project Report (EPR). Cadreatech manages the full NEMA licensing process, including stakeholder engagement and license renewal.
Water Resources Authority (WRA) Permits
The WRA regulates water resource management under the Water Act, 2016. Permits are required for borehole drilling, groundwater abstraction, wastewater discharge, and construction near water bodies. Cadreatech’s engineers conduct hydrogeological assessments, design water supply and wastewater systems, and prepare WRA permit applications that meet regulatory standards for sustainable water use.
Kenya Building Code Standards
The Kenya National Building Code provides technical standards for construction design, materials, workmanship, and safety — covering structural safety, fire protection, accessibility, energy efficiency, and environmental sustainability. Cadreatech designs all projects in accordance with the Kenya Building Code, British Standards (BS), and Eurocodes where applicable, ensuring your building meets international quality standards.
Professional Indemnity Insurance
EBK requires all registered engineers to maintain professional indemnity insurance covering potential liabilities arising from engineering services. This protects both engineer and client in cases of professional errors, omissions, or design failures. When you engage Cadreatech, you benefit from comprehensive professional indemnity coverage that demonstrates our commitment to professional accountability.
Structural Design Certification & Engineering Stamps
All structural engineering drawings submitted for building approval in Kenya must be signed and stamped by an EBK-registered structural engineer. The stamp certifies compliance with applicable codes, loading standards, and safety requirements — legally required for all permanent buildings, bridges, retaining walls, and load-bearing structures. Cadreatech’s structural engineers provide certified designs with full supporting documentation.
Construction Site Supervision & Certification
EBK and NCA regulations require qualified professional supervision throughout construction. The supervising engineer or architect must conduct regular site inspections, certify completed works, and issue stage completion certificates for foundations, structural frame, roofing, and final handover. Cadreatech provides full supervision services with weekly site visits, progress reports, quality control testing, and certification documentation.
