Geri Alimi Underpass: Over N100m unaccounted for — ENetSuD Report

A Kwara-based civil society organization, Elites Network for Sustainable Development, (ENetSuD) has submitted a social audit report on the Geri Alimi underpass project executed by the erstwhile administration in the state capital, Ilorin, to the Kwara State Government.

Following the approval of the present administration to scrutinize six projects carried out by the its predecessor, ENetSud had submitted reports of four projects, including; College of Education Road Ilorin (ENetSuD/KWSG/01/26), Government High School Ilorin (ENetSuD/KWSG/01/27), Ilesha Baruba – Gwanara Road (ENetSuD/KWSG/01/29), and Patigi Secondary School, Patigi (ENetSuD/KWSG/01/30).

According to the report signed, on Monday, by the ENetSuD coordinator, Dr. Alagbonsi Abdullateef, the organisation saddled with the responsibility of promoting good governance and monitoring of public funds in the interest of the citizen revealed that the Bill of Engineering Measurement and Evaluation (BEME) of the Geri Alimi Underpass Project provided to them was reexamined and it was evident that the contract sum of Three Billion, Six Hundred and Thirty-nine Million, Four Hundred and Forty-four Thousand, Six Hundred and Fifty-nine Naira (₦3,639,444,659:93) was accurate.

A part of the report read: “Considering the nature of the project, many structures are buried underground and could have been measured accurately only during the execution stage. Our assessment has a lot of limitations because it was impossible for us to measure what we did not see. Thus, we were neither able to access nor assess many components of the project.

“A few components were assessable, and we were able to calculate a questionable shortage of about One Hundred and Seven Million, Eight Hundred and Three Thousand, One Hundred and Fifty-five Naira (₦107,803,155) (subject to our final coring test) from those few components only.

“We speculated that there might be a lot of other shortages that we were unable to determine, but we limited our quantification to what could be objectively measured without ambiguity. We did this in good faith to avoid any form of misinterpretation of facts.”

ENetSuD therefore called on the Kwara State Governor, Abdulrahman Abdulrazaq, to consider and approve: The return of the contractor to the site to work on the project shortages as per the approved specifications in the BEME; the contractor should justify shortages worth at least ₦107,803,155 as detailed in the full report; A 1-day release of coring machine by the Ministry of Works to ENetSuD for coring test of the road to ascertain the thickness of all the specified layers as per the approval in the BEME.

Bill 1 (out of five bills that the report was divided to) titled ‘General and Provisional items,’ read: “The existence of the site office (cost: ₦2,500,000) during the project execution could not be ascertained. The present status of the project vehicle (cost: ₦19,025,750) procured for the consultants during the execution of the project is not known. We strongly believe that the vehicle should have been returned to and become the property of KWSG.

The report also stated that a lot of provisional items in Bill 1 are questionable and should be defended by the Ministry in charge.

“A provisional sum of ₦17,000,000 was billed for the provision and erection of road signs. The specific number of these signs need to be clearly stated to know if it is reasonably equivalent to the sum. However, we found only 4 road signs. How this costs ₦17,000,000 need to be questioned critically.

“A provisional sum of ₦15,000,000 was billed for the provision of road marking. However, we found road markings of 132 meters only at the underpass. How this costs ₦15,000,000 need to be questioned critically. A provisional sum of ₦50,000,000 was billed for compensation and acquisition. We were not able to determine if this sum was truly used for compensation or not, and to what extent it was used.

“A provisional sum of ₦102,298,426 was billed for the removal and relocation of existing service installations for electricity, telephone, water supply and other utilities along the alignment. We confirmed that the water main was diverted and existing pipes were relocated. We also confirmed
that the existing electrical installation was diverted along Sawmill to Olorunsogo. However, is was impossible for us to ascertain if the quantum of the removal and relocation works done was as much as the billed amount (₦102,298,426).

“A provisional sum of ₦1,500,000 was billed for the provision of personal computers, printers, video camera, software, and accessories as may be required by the Engineers’ representatives. While the exact quantity of items provided was not stated and not also sighted, it is important to
verify if all the procured items were returned to the KWSG as we believe that they should remain the property of the State.

“A provisional sum of ₦7,500,000 was billed for the site confirmatory investigation and deep boreholes before and during construction works. There is a need to determine the actual borehole points to ascertain their existence. However, our findings suggested that a borehole was drilled and sited along sawmill route and was channeled back to the central post, leaving it inaccessible to the populace.

“A provisional sum of ₦10,000,000 was billed for the erection of the police post. We found a fabricated framework provided by the contractor as the police post. However, the billed amount (₦10,000,000) needs to be questioned. A provisional sum of ₦80,000,000 was billed for the electrification of the project. Truly, electrification was done, but a detailed Bill of Quantity to breakdown the sum is required to enable proper re-assessment of the electrification works and determine if the works done are equivalent to the sum. However, we found some streetlights and CCTV on the site.

“A provisional sum of ₦10,000,000 was billed for the provision of water supply and sprinter services. We found 6 nos but we don’t know the exact number that ought to be provided based on the billed sum.”

The bill 2 consisted of scarification of existing pavement carriageway and shoulders, shaping and compaction to receive additional fill material (₦12,351,600), excavation and hauling of materials (except rock) to other locations (₦98,409,600), excavation of materials in rock formation and side drains and hauling to other locations (₦38,438,097), and excavation from approved borrow pits, hauling, deposition and compaction on carriageway and shoulders (₦26,326,646).

Other areas highlighted in bill 2 include; Excavation of unsuitable material below formation in cuttings and side drains except rock and hauling to spoil (₦20,214,096), dubbing in grass to shoulders and slopes of embankment (₦225,774), excavation from approved borrow pits, hauling, deposition and compaction as backfilling for culverts and washed embankments (₦28,903,770), excavation of unsuitable materials below subbase level and replacement with hardcore and blinding with sharp sand or equal filter material (₦8,250,000).

All the earthworks listed under Bill 2, according to the report, were unable to be evaluated by ENetSuD as the project had been completed. However, available pictures suggested that they were done. “Since we were
not able to quantify these items, we cannot conclude whether the sum of ₦233,119,585 used for the items in Bill 2 was appropriately spent or not,” it added.

“A sum of ₦825,190 was billed for the demolition and removal of 89.89m failed pipe culverts including wing walls, aprons, and headwalls. Since we did not witness the quantity of what was demolished and removed, we were unable to assess and quantify this item,” Bill 3 of the report, tagged ‘Culverts and Lined Drains,’ stated.

“A sum of ₦5,218,560 was billed for the demolition and removal of 1,920m existing failed lined drain. Since we did not witness the quantity of what was demolished and removed, we were also unable to assess and quantify this item.

“A sum of ₦29,190,699 was billed for the excavation of 6,875.32 m3
of non-rock and rock materials for storm pipe as a lined drain, backfilling, compaction and disposal of surplus materials. We were also unable to assess and quantify this item. A sum of ₦12,052,972 was billed for the provision of 373m of 750mm x 600mm x 125mm concrete grade 25 in lined drains including reinforcement and shuttering. We were also unable to
assess and quantify this item, but we had an impression that it was executed as seen in the pictures.

“A sum of ₦84,955,392 was billed for the provision of 1,928m of 600mm balloon drains as storm pipe including sand bedding, hunching and surround, and shuttering. We were also unable to assess and quantify this item, but we had an impression that it was executed as seen in the pictures.
VI. A sum of ₦40,281,411 was billed for the provision of 629m of 900mm balloon drains in the median. We were also unable to assess and quantify this item, but we had an impression that it was executed as seen in the pictures.

“A sum of ₦10,196,121 was billed for the provision of 58 nos reinforced concrete manhole along the profile of the diameter 600 mm storm pipes. However, we found 61 nos of these manholes. This is equivalent to an excess of ₦527,385.6.

“A sum of ₦4,894,848 was billed for the provision of 14 nos reinforced concrete manhole along the profile of the diameter 900 mm storm pipes. We found 23 nos of this.

We measured 7,173 meters without being able to differentiate the types. Using the rate of Type 1, this is equivalent to a shortage of ₦4,918,478.

“A sum of ₦35,424,113 was billed for the provision and laying 4,815.58 m2
of precast interlocking paving stone walkway with keying edges concrete. However, we found 4,793.05 m2 of stamp concrete in the site instead of 4,815.58 m2 provided in the BEME. This is equivalent to a shortage of ₦165,734. A provisional sum of ₦63,793,548 was billed for the provision of sub-drain. The quantity of the sub-drain that warranted this huge amount was not stated in the BEME. We were unable to assess it.

“A sum of ₦2,415,000 was billed for the provision and laying of 46 meters’ concrete barricade between the two bridges including 50mm diameter galvanized pipe. However, we found a barricade of 40 meters instead of 46 meters provided in the BEME. This is equivalent to a shortage of ₦315,000.”
