Verifying credentials by auditing National Construction Authority (NCA) active licenses, confirming tax compliance, and physically inspecting ongoing job sites.

Statutory Licensing and Legal Registration Audits

When you choose a contractor, verify their NCA registration category (NCA 1 through NCA 8) to confirm legal clearance for your project's financial scale.

For your information, over 30% of building collapses in Kenya stem from unqualified, unaccredited builders undertaking structural works beyond their class limit.

Physical Site Visits and Historical Portfolio Verification

Relying solely on phone references exposes your investment to severe risk.

Mandate unannounced site visits to current and completed builds to assess artistry, site safety protocols, material storage quality, and worker supervision levels.

Reviewing an active build will give you an accurate benchmark for a contractor hiring checklist.

Ignoring warning signs during contractor selection exposes your development capital to immediate fraud, project stagnation, and severe litigation liabilities.

Below are the key warning signs to watch out for when choosing a contractor:

Abnormally Low Bids and Unrealistic Bills of Quantities

Unscrupulous builders submit lowball estimates to secure contracts, only to trigger massive variation claims during civil works.

So, watch out for an abnormally low bid. It indicates intent to use substandard materials or skip critical structural engineering steps.

Demands for High Upfront Cash Mobilization Fees

Never advance large cash deposits before work commences. When a contractor demands more than 10%-15% as upfront mobilization cash, it signals poor liquidity.

Reputable builders maintain credit lines with material suppliers. Thus, they can start site clearing and excavation activities without draining client reserves.

Unregistered Subcontractors and Non-Compliant Site Practices

Operating without registered supervisors and valid safety permits invites swift regulatory action.

Notably, the NCA issues immediate site closure notices, halts construction, and levies heavy administrative fines on non-compliant property owners.

Disposing of Debris on Riparian Land and Unauthorized Sites

Using unapproved haulers to dump excavated soil on riparian zones triggers aggressive enforcement by NEMA.

In this event, NEMA holds both the contractor and the developer jointly liable. Consequently, the authority issues stop-work orders and forces immediate site remediation at your expense.

You protect project capital by tying disbursements to certified completion milestones, executing standard JBC contracts, and withholding a 5% to 10% retention fee.

Milestone-Based Payments and Retention Funds

Always disburse via valuation certificates. Release funds only when an independent quantity surveyor validates site milestones.

Also, maintain retention reserves by withholding 5% to 10% of the total contract value. This value will serve as a defects liability retention fund for 6 months after handover.

Legally Binding Contracts and Dispute Resolution Clauses

Use standard Joint Building Council (JBC) contract templates containing explicit completion timelines, delay penalty clauses (liquidated damages), and formal arbitration procedures.

Remember, a clear agreement is the most effective tool on your contractor hiring checklist.

Executing structured due diligence transforms the process of choosing a contractor from a high-risk gamble into a secure business transaction.
