A contractor tasked to redevelop the UNDP flats at Cantoments in Accra says he has had to give up his work following unending harrasment from National Security officials.

Ebenezer Amanor told Joy News' Parker Wilson, his workers have been beaten, suppliers of building materials have been attacked.

"I was kicked and slapped", he said following a change in government in 2017, a year after his company won the contract.

The UNDP flats is a four-storey building fitted with 48 apartments and built in the 60s. But time has downgraded the building's once plush looks leaving it in need of repairs.

Walled, the building looks wearied from extreme weather patterns. It needs painting and a facelift for a place which housed Ghanaian officials working at the UNDP office in Accra.

The John Mahama administration marked it for redevelopment to be given out to clients in the high-end housing market.

Around the Clock Consortium began work in March 2017 and were expected to complete their work by 2018. But workers of the company have been harassed around the clock, Amanor lamented.

Parts of the flat torn down for reconstruction have been repaired by some National Security operatives who live in the building and have resisted the contractor, he said.

They used materials he had bought for re-construction to put back the building.

The contractor says his car was once seized and he was once threatened a night behind bars by aggressive security officials who want him off the site.

Already, he has been chased out of his site office. "They have taken over completely" he lamented.

Around the Clock consortium was paid at least 30% of the contract sum but work on the site is barely 30% of the reconstruction plan.

And while activities of National Security officials stall the project, the cost of the reconstruction keeps going up.
