NCA Proposes Premix Concrete for Storied Buildings
By James Kariuki
The National Construction Authority (NCA) has proposed that construction works for buildings above three floors be done using pre-mixed concrete delivered on site by licensed subcontractors.
NCA's Buildings Inspectorate Secretary Moses Nyakiongora said they had also proposed that no onsite mixtures would be condoned.
The move is aimed at reversing the trend where houses have been collapsing due to use of poor quality materials and poor workmanship.
The quantity surveyor spoke when he witnessed the launch of a Sh15 million mobile testing laboratory by Bamburi Cement that will help contractors at sites using Bamburi products ascertain quality of sand and aggregates before mixing.
