Kenya’s rapid urbanization and infrastructure boom demand a level of construction quality and reliability that only the highest-rated contractors can provide. In the construction sector, NCA1 certification represents the pinnacle of capability, allowing firms to undertake unlimited project values and the most complex works.

At Jumba Engineering Services Ltd. (Jumba Engineering), we are proud to be an NCA1-licensed contractor, bringing over 40 years of engineering excellence to Kenya’s mega projects. From housing developments to mixed-use malls, our focus has always been on delivering projects that stand the test of time through robust design, compliance, and rigorous quality assurance.

What NCA1 Certification Means

The National Construction Authority (NCA) categorizes contractors in Kenya based on their capacity, experience, and resources.

  • NCA1 is the highest classification.

  • It allows contractors to handle projects of unlimited value and complexity.

  • Certification requires strict compliance with the Kenya Building Code, safety standards, and proof of technical and financial capacity.

For clients, working with an NCA1 contractor means assurance of:

  • Technical expertise backed by registered engineers.

  • Financial strength to manage large projects.

  • Regulatory compliance with NCA and EPRA.

  • Accountability through government oversight.

The Jumba Engineering Quality Framework

At Jumba Engineering, quality is not just about meeting codes — it’s about exceeding expectations. Our approach includes:

  1. Integrated Project Design

    • Early coordination of civil, structural, and MEP (mechanical, electrical, plumbing) elements.

    • Use of Building Information Modeling (BIM) to detect clashes before construction begins.

  2. Material Quality Control

    • Testing all materials in certified labs.

    • Ensuring cement, steel, and aggregates meet KEBS and BS/ASTM standards.

  3. Site Supervision & Skilled Workforce

    • EBK-registered engineers supervising works.

    • Skilled technicians and artisans trained in-house.

  4. Health, Safety & Environment (HSE)

    • Compliance with OSHA 2007 and ISO 45001.

    • Full PPE, safety drills, and risk assessments on site.

  5. Quality Assurance (QA/QC)

    • Factory Acceptance Tests (FAT) and Site Acceptance Tests (SAT).

    • Continuous inspections at every stage of construction.

Case Study: Kisumu 140 Housing Units

Jumba Engineering was contracted for electrical installation works at a 140-unit housing development in Kisumu.

Challenges:

  • Tight timelines imposed by the client.

  • Integration of power, water, and ICT infrastructure.

Solutions:

  • Adopted phased construction to parallelize works.

  • Used pre-cast panels and modular electrical distribution systems.

  • Applied BIM coordination to prevent costly reworks.

Impact:

  • Project delivered on time and within budget.

  • High client satisfaction and compliance with NCA quality benchmarks.

Why Quality Control Matters in Mega Projects

Mega projects involve multiple stakeholders, high budgets, and complex integrations. Without stringent quality control, risks include:

  • Structural failures.

  • Delays and budget overruns.

  • Safety incidents.

  • Non-compliance with regulators (leading to fines or shutdowns).

By choosing an NCA1 contractor like Jumba Engineering, clients mitigate these risks.

Future Outlook: Smart & Green Construction

The next frontier for construction in Kenya is sustainability and smart buildings. Jumba Engineering is already integrating:

  • Green building practices (energy-efficient designs, solar integration).

  • ICT infrastructure for smart monitoring.

  • Eco-friendly materials to reduce carbon footprint.

This aligns with Kenya’s Vision 2030 and global ESG (Environmental, Social, Governance) expectations.

Benefits to Clients

  • Peace of mind knowing the project is in safe hands.

  • Regulatory compliance with NCA, EPRA, and KEBS.

  • Higher ROI through durable and efficient infrastructure.

  • Enhanced reputation for developers partnering with NCA1 firms.

Why Jumba Engineering?

  • NCA1-licensed contractor with proven capacity.

  • 40+ years of engineering excellence in Kenya.

  • Strong portfolio: Kisumu housing units, Shujaa Mall, mixed-use developments.

  • Integrated services: construction + electrical + solar + ICT.

  • A culture of safety and quality rooted in ISO standards.
