Ogun Govt Orders Revision Of Engineering Design On Gbenga Daniel’s Constituency Project

Ogun State government has ordered the contractor handling Senator Gbenga Daniel’s constituency road project in Sagamu to develop a new design that conforms to the state’s required engineering specification.

The government, in a letter addressed to the contractor dated 22nd September 2025 and signed by the Permanent Secretary in the state’s Ministry of Works, Engr. Yusuf I. O expressly faulted the bill of quantities submitted by the contractor on the ground that it lacked clarity on the specific portion that the road reconstruction covers.

The 260-metre Paddy Arikawe Oye Igbimo road project in Sagamu is part of a proposed 3-kilometre stretch constructed in four phases.

While approval was only granted for the first phase, the contractor had begun work earlier without state approval, prompting the government to demand due process.

The ministry also raised concerns over the quality of the materials proposed for the work, directing that concrete binding should be Grade 20, while reinforced concrete base, walks, and deck must be Grade 25 minimum, with a high yield tensile strength of not less than 460 N/mm2.

The contractor was instructed to replace the proposed 150mm concrete pavement of Grade 20 with a 220mm thick reinforced concrete pavement of not less than Grade 35, preferably Grade 40, and to increase the thickness of the stone base to 200mm.

The letter also demanded a complete layout with elevation and grades, detailed drawings of concrete pavement with reinforcement at the joints, a list of engineering materials, and evidence of quality assurance testing. It further directed the contractor to include design criteria codes in all revised submissions.

While acknowledging the contractor’s eventual step of seeking state approval, the government maintained that only designs that meet established engineering standards would be accepted to ensure durability and value for taxpayers’ money.
