CIDB Grading Explained for Construction Businesses

Running a construction business is very taxing but also rewarding. Construction businesses are highly lucrative enterprises, and there are various ways to get into the industry. Like all other sectors in South Africa, there are certain regulatory requirements you need to meet, especially if you want to get government contracts. One of those is getting your Construction Industry Development Board (CIDB) grade.

South Africa’s construction sector contributes roughly 2,3% to 2,4% to national GDP and employs approximately 1,3 million to 1,35 million workers. Analysts at Global Data, an international data and analytics company specialising in industry forecasting, expect the sector to grow by around 4,3% annually between 2027 and 2030, powered by infrastructure investment and renewable energy projects.

For small to medium-sized enterprises (SMEs) looking to get construction tenders, you must get your grading done beforehand. In this article, we look at some of the trends around South Africa’s construction industry, what CIDB grading is and what the requirements are.

South Africa’s Construction Industry: Trends

The following trends are what business leaders need to keep note of to keep pace with the industry.

1. Acceleration in Infrastructure Investment

In his 2026 Budget Speech, Minister of Finance Enoch Godongwana confirmed that public-sector infrastructure spending will exceed this amount over the medium term, which should bring renewed momentum to the South African construction sector.

The funding pipeline outlined in the 2026 budget speech is set to reach several levels of government, comprising R577,4 billion for state-owned companies, R217,8 billion for provinces and R205,7 billion for municipalities. The largest share is set to go towards transport and logistics projects.

While the increased investment is a good signal, Infrastructure South Africa has repeatedly warned that poor preparation and misaligned budgets threaten to derail construction work before it even begins.

2. Growing Number of Women in the Construction Industry

Construction is still considered to be a male-dominated industry. However, women’s participation is increasing significantly. Targeted programmes are helping female-led businesses and contractors make a bigger impact on the industry.

The gap for women is in finance, with women-owned SMEs accounting for 36,1% of all funding applications, yet the number of women-targeted finance products has dropped by 33%.

3. Public-private Partnerships Present New Pathways

Public-Private Partnerships (PPPs) are being encouraged in the construction sector through regulatory reforms, positioning them as a new primary delivery model. According to South Africa’s National Treasury, public-sector infrastructure spending will total R1,06 trillion over the medium-term expenditure framework (2026–2029), with PPPs increasing steadily to an estimated R7,8 billion by the end of 2026.

Sixty-three PPP projects are currently in development across rail, border infrastructure, energy transmission and municipal services, with several expected to reach financial closure in 2026 – and become the first to do so since the pandemic.

4. Skilled Labour Shortage and Digital Adoption

South Africa has a damming specialised skills shortage, which is only getting worse. In 2025, 38% of South African employers struggled to find engineers, up from 23% in 2024 and just 14% in 2018, a worrying trend that shows no signs of easing.

The industry’s response to the labour shortage is digital adoption. Tools like BIM, drones, IoT sensors and reality capture have progressed from an experimental phase to being key parts of complex projects. Adoption may be inconsistent because of infrastructure gaps and a large informal sector, but momentum is picking up.

5. Cash Flow and Capital Structure are Challenges

One of the biggest challenges in the construction industry in South Africa is managing cash flow between project milestones. Large upfront costs for construction materials, delayed invoice payments, drawn-out procurement cycles and retention payments all add to the pressure of keeping construction businesses open.
Add that with geopolitical issues such as US tariffs, which disrupt import supply chains and growing energy costs, it’s easy to see how businesses struggle.

What is the CIDB and CIDB Grading?

Established by the Construction Industry Development Board Act, the Construction Industry Development Board (CIDB) is a Schedule 3A public entity which promotes a regulatory and developmental framework that:

• Builds construction industry delivery capability for South Africa’s social and economic growth.
• Builds a construction industry that matches global competitive standards.

The focus of the entity is on:

• Sustainable growth, capacity development and empowerment
• Improved industry performance and best practice
• A transformed industry underpinned by consistent and ethical procurement processes
• Enhanced value to clients and society

What is CIDB Grading?

CIDB grading is a ranking system used by the CIDB to classify construction contractors from grade 1 to grade 9. Grading is based on two key determinants – construction works or track record and available capital. Capital relates to funds presumed available to a contractor to start a new project.

CIDB Primary Classes

A CIDB registration is only valid for the specific class of works in which the contractor has demonstrated competence. Contractors may register in multiple classes if they can provide the necessary track record for each. The different classes are:

• General Building (GB): Construction, renovation or dismantling of permanent shelters – domestic dwellings, commercial buildings, schools, hospitals.
• Civil Engineering (CE): Engineering infrastructure – roads, railways, bridges, water treatment plants, dams, sewerage systems.
• Mechanical Engineering (ME): Installation or maintenance of mechanical infrastructure – HVAC, gas transmission, solid waste disposal, manufacturing.
• Electrical Engineering in Building (EB): Electrical systems in premises – from points of control to consumption points (wiring, lighting, distribution).
• Electrical Engineering in Infrastructure (EP): Generation, transmission and distribution of electricity across larger grids – power stations, substations.

There are also specialist subcategories which include codes for asphalt works (SB), corrosion protection (SD), demolition and blasting (SE), and fire prevention and protection systems (SF).

CIDB Grades 1-9

Grade 1: R500 000 maximum tender value with no prior experience needed. (Cost: R450)

Grade 2: R1 million maximum tender value, the largest tender fulfilled over the past five years must be worth R130 000.

Grade 3: R3 million maximum tender value, the largest tender fulfilled over the past five years must be worth R450 000.

Grade 4: R6 million maximum tender value, the largest tender fulfilled over the past five years must be worth R900 000.

Grade 5: R10 million maximum tender value, the largest tender fulfilled over the past five years must be worth R1,5 million.

Grade 6: R20 million maximum tender value, the largest tender fulfilled over the past five years must be worth R3 million.

Grade 7: R60 million maximum tender value, the largest tender fulfilled over the past five years must be worth R9 million.

Grade 8: R200 million maximum tender value, the largest tender fulfilled over the past five years must be worth R30 million.

Grade 9: No limit on maximum tender value, the largest tender fulfilled over the past five years must be worth R90 million.

Requirements and Application for CIDB Grading

When applying for CIDB grade 1, you will need to apply on the eRoC portal. You will need the following:

• Log-in details (CRS number, e-mail, and password).
