The review into the controversial $17 million price tag for the 'Welcome to Montego Bay' sign has found that the estimated figure is insufficient for the execution of the works.
The review was conducted by Quantity Surveying firm Davidson & Hanna.
Davidson & Hanna says most of the rates were found to be in line with market prices.
However, it says the estimates for the wall cladding, lettering and signage were low.
The Tourism Product Development Company (TPDCo) last month provided a breakdown of the $17 million budget.
The TPDCo said that $8 million would be spent on creating a dual base facing the east and west, $3 million on lettering, $2 million on electrical work, $1 million on irrigation and $3 million for contingencies.
Tourism Minister Edmund Bartlett has now instructed that the $3 million contingency be reduced to no more than ten per cent of the total project cost.
But with the private sector's injection of $5 million, Mr. Bartlett said he expects the new attraction will come in well within budget.
Mr. Bartlett last month instructed the Permanent Secretary to conduct a full review of the costs associated with the sign after the parliamentary opposition and some residents said the cost was too high.
