Questions
Asked before a quotation.
What size of road contract can you sign?
Elevion is registered with the National Construction Authority as an NCA 7 road works contractor, which covers road contracts of up to KES 50,000,000 each. A works contract also needs a current NCA annual practising licence; the tenders page shows its status.
Do you maintain existing roads?
Yes. We patch potholes, clean drains and cut grass as routine work, reseal and overlay as periodic work, repair washouts as emergencies, and improve failed sections.
Can you work on a road that stays open to traffic?
Yes. We plan the works in sections, with signs and flag controllers, so the road stays passable.
