How construction disputes arise
Disputes rarely begin as a disagreement about the law. They begin as an unresolved commercial position that has been left to harden. The recurring causes on projects in Kenya are:
- Variations executed without being valued at the time, so their value is reconstructed months later from incomplete records.
- Claims submitted late, without the notices the contract required, and therefore resisted on procedure rather than merit.
- Delays where no one established which events actually affected completion, leaving both parties with a list of grievances rather than an analysis.
- Final accounts left unsigned, so retention is never released and the contract never closes.
- Payment certificates issued late or not at all, or payments made outside the period the contract allowed.
- Interpretation of the contract conditions — what a clause required, what a notice had to contain, and when it had to be given.
The practical consequence is that the strength of a construction case usually depends on the contemporaneous records rather than on the strength of the argument. Notices, programmes, instructions, valuations and site records decide these disputes.
