The plan by the Ebonyi State government to rehabilitate the runway of the recently commissioned state-owned airport at Onueke, Ezza South Local Government Area, has drawn condemnation from the members of the public.
One of the stakeholders spoken to by Daily Independent alleged that the so-called rehabilitation of the runway was to recover campaign funds and divert public resources.
The airport, which was commissioned on April 26, 2023 by Engr. David Umahi, the immediate past governor of the state, gulped the federal and state governments about N36 billion to construct at the time of its commissioning.
Umahi had said that the airport would be handed over to the Federal Government for proper concessions.
But Francis Nwifuru, the governor of Ebonyi State, said last week that the government would rehabilitate the five-month-old runway at the sum of N13 billion.
Speaking through Mrs. Ngozi Obichukwu, Commissioner of Aviation and Transport Technology, Ebonyi State, the government attributed poor construction of the runway to its plan to rehabilitate the facility.
The government argued that the past government should have used asphalt for the runway, rather than the concrete pavement, which was used.
Already, the state government said it had awarded the contract for the rehabilitation of the airport to Infrastructure Development Company (IDC) and mobilised the contractor by 50 percent of the total contract sum.
The contractor is expected to hand over the airport to the state government within eight months for commencement of flight services, according to the government.
But checks by Daily Independent showed that most newly constructed airports have concrete runways and they are typically for major and bigger commercial airports.
Concrete has a cement-based binder, while asphalt is bitumen. Although it takes longer to install concrete compared to asphalt, there are higher upfront costs involved.
However, runways made from concrete are often more economical over time, provided they receive the required maintenance.
Those spoken to by Daily Independent said the state government could have been ill-advised by some persons to scrape some portions of the concrete runway, while others suspected foul play.
Commenting on the issue, Dr. Alex Nwuba, President, of the Aircraft and Owners Pilots Association of Nigeria (AOPA), said that concrete runways are always better and stronger than asphalt runways unless not properly done and wondered why the state government was bent on scrapping the runway.
Nwuba explained that rather than waste public funds on the rehabilitation of the facility, the government should have focused its attention on developing traffic to the airport, which it said was to attract economic development to the state.
He said: “The former governor of Ebonyi State who is now the Minister of Works and an engineer has stated that roads built in the country are of poor quality and he aims to improve on them, while at home he’s being accused of substandard runway.
“If the allegation is that asphalt is superior to concrete, then it’s wrong unless the concrete wasn’t handled properly, in which case I’d have expected a correction rather than an upgrade to less. I wish Ebonyi well, I’d expected the focus should have been on developing traffic to the airport, which it will need eventually after using up resources.”
Grp. Capt. John Ojikutu (rtd.) said that concrete runways are more expensive than asphalt runways, but said it may not be required for the full length of the runway.
For instance, he mentioned Makurdi airport as the first aerodrome with concrete runway in the country since 1978/79, yet without any major repairs over four decades after.
“The Makurdi runway was built of 4 kilometers in full concrete about 1978/79 and I am not sure it has gotten any serious defect since then,” he said.
Capt. Samuel Caulcrick, the past Rector of the Nigerian College of Aviation Technology (NCAT), Zaria, said that local conditions or terrain of the airport determines the choice of materials for runway pavements.
Caulcrick, however, said that concrete was the choice pavement for major airports, where the ground conditions permit, giving the most satisfactory type of pavement for long-term minimum maintenance.
He explained that resorting to asphalt runways would mean downgrading of the runway and cautioned the state government against such a step.
Engr. Sheri Kyari, former staff of the defunct national carrier, Nigeria Airways, like others, said that concrete runways are more durable than asphalt.
He, however, stated that concrete runways are prone to cracks, but said Ebonyi airport was still new without any need for repairs at the moment.
He suspected that the rehabilitation of the airport’s runway may be another means for the state government to recover campaign funds and divert public funds.
“Again, if they want to just add a layer of asphalt to cover the top layer, fine, but the bottom line is that they just want to siphon money and that can only be done through large projects. This is to recover campaign funds,” he said.
Besides, Capt. Mohammed Badamasi, an aviation stakeholder, declared that modern runways are made from concrete aggregate.
Badamasi stressed that this is preferred, due to its superior durability, and weight-bearing capabilities, positing that it is more expensive to construct.
He clarified that concrete aggregate for runways is slightly different from what is used in pavement and road construction, maintaining that the concrete mix must meet the highest international standards in runway construction.
He, however, suspected that the runway may have been poorly built by the past government to have warranted its scraping.
He posited that a properly constructed concrete runway is expected to last for at least 20 years, while asphalt is expected to last for 10 years before any form of repairs could be carried out on it.
He added: “Asphalt is a cheaper alternative, often used with a lower load bearing expected on the runways. I won’t be surprised if the runways in question in Ebonyi State were poorly built. Signs of deterioration of the runways are cracks on the surface of the runways.
“Since it’s not possible to patch concrete runways, the best thing to do is to remove the concrete surface and replace it with an asphalt surface. Whichever type is chosen, the durability of the runways will depend on the quality of work done by the contractor.”
Recall that the former governor, Umahi, had commissioned the airport in April, this year, with an inaugural flight operated by Air Peace with its two Embraer 145 aircraft from the Nnamdi Azikiwe International Airport (NAIA), Abuja and the Murtala Muhammed Airport (MMA), Lagos touched down at the airport.
Umahi had named the airport after former President Muhammadu Buhari, but the new government in the state renamed it Chuba Okadigbo’s International Airport, a few weeks after assumption of office.
Umahi had informed that the Federal Government approved the sum of N10 billion for the take-off of the project, apart from other support received from the government to ensure its completion.
