When the Committee expressed its displeasure about the under-spending, the PoEC explained that many factors had contributed to the under-spending. These included: . The awarding, by the Department of Public Works, of infrastructure projects to emerging contractors who have cash-flow challenges; . State Information Technology Agency (SITA) delays in billing because their invoices come from their head office; and . A high staff turn-over due to conditions of employment - appointment only on contract.
