Dutch firm selected to conduct new Demerara bridge feasibility study.

A Dutch consultancy firm has been selected to conduct a feasibility study for the construction of a new bridge across the Demerara River, according to Minister of State Joseph Harmon, who said that the design, location and financing options are among the things to be addressed.

Harmon identified the firm as LievenseCSO and he also said the study is the final stage of the process before construction starts.

Speaking during a post-Cabinet press briefing at the Ministry of the Presidency, Harmon yesterday noted that Cabinet this week approved a request by Minister of Public Infrastructure, David Patterson for the feasibility study to be conducted. He reminded that a pre-feasibility study was done by the Demerara Harbour Bridge Corporation in collaboration with the Public Infrastructure Ministry in 2013. That study, he said, concluded that a new high level fixed bridge was the best option to be pursued.

The existing bridge has been in operation since 1978. The design and construction of a new bridge has been under discussion for some time in light of concerns about the design life of the existing bridge, although these have been questioned.

During this year, Harmon said, the Ministry of Public Infrastructure advertised for suitable consultants to conduct a feasibility study that would lead up to the construction of the bridge through a private-public partnership model.

According to Harmon, the ministry has since received an offer from LievenseCSO, which is a recognized Dutch consultancy firm, to conduct the feasibility study and design for the new bridge as well as a detailed investigation for prospective financiers and the preparation of a private-public partnership tender document. He said that it is expected that the feasibility study will commence in January, 2017.

While he knew when the study will start, Harmon was unable to say when the study is expected to be completed. “But based on the extent of the work that has to be done, we are advised that they would basically try to push it so at least we can have a bridge in a reasonable time,” he said.

He was unable to confirm the proposed location of the new bridge.

Explaining the need for a second feasibility study, he said that in these types of constructions, there is a pre-feasibility study, followed by a feasibility study. “So we are at the second stage. The pre-feasibility examines several things that are required to be examined and they sort of narrow down the option of the feasibility. So the feasibility has a more limited area, which they have to consider….the model, the private-public partnership model….the tender documents, they have to look at various sites, the sites that might have been in the prefeasibility and to actually determine whether in fact this is something we can go forward with. This is the final stage of feasibility before you actually get to construction,” he pointed out.

Where is Caribj, like his paycheck ain't come in yet this week?  Is a wonder the PNC crew ain't screaming that they have enough PNC Black engineers to do the feasibility study, so why they had to bring in the White man?

Demerara  Harbour Bridge was designed by Johan Coghlan, a Guyanese Civil Engineer.

Interesting that now the Granger government has engaged the services of a Dutch consultaing company to undertake the works.

Of note, another Guyanese Civil Engineer was the lead person who was responsible for the construction of the works.

Perhaps, no Guyanese local company with Civil Engineers are now capable of doing the works.

A Dutch firm has been selected to conduct a feasibility study for the construction of a new fixed high-span bridge across the Demerara River.

Minister of State, Joseph Harmon said Leivencse CSO’s feasibility study will examine the possibility of a public-private partnership. Website: http://www.lievensecso.com/

“This is the final stage of feasibility before you actually get to construction,” Harmon told a post-cabinet news conference.     

Leivencse CSO, Harmon said, was selected through the procurement process by the National Procurement and Tender Administration Board.   

He said a pre-feasibility study done by the Demerara Harbour Bridge Corporation in 2013 shows that there is need for a fixed high-span bridge across the Demerara River. The current bridge has a retractor span that opens to allow ships to pass.

The 1.5 mile long Demerara Harbour Bridge was officially opened in July 1978 and was projected to have a 10-year lifespan. It is still in operation… (see video and other information below)

Demerara Harbour Bridge – (Wikipedia)

The Demerara Harbour Bridge is a 6,074-foot (1,851 m) long floating toll bridge. It was commissioned on 2 July 1978. The bridge crosses the Demerara River 4 miles (6.4 km) south of the Guyanese capital Georgetown, from Peter’s Hall, East Bank Demerara to Schoon Ord, West Bank Demerara. There is a pedestrian footwalk. A raised section lets small vessels pass under. A retractor span lets large vessels pass. Construction of the Demerara Harbour Bridge began on 29 May 1976. Construction assistance was provided by the British Government, but the basic design was by a Guyanese, Capt. John Patrick Coghlan. The bridge was only designed to last 10 years, yet it is still going strong.[1] Toll is collected only in one direction of travel even though the bridge handles one lane of traffic in each direction. Traffic going west to east pays no toll.

The bridge is exactly 1.25 miles (2.01 km) long and has 61 spans. A high-level span provides a horizontal clearance of 32.0 metres (105 ft) and a vertical clearance of 7.9 metres (26 ft) to let small craft pass at all times. To let large craft pass, two retractor spans retract fully to leave a horizontal clearance of 77.4 metres (254 ft).

History

The expanding country needed a way to transport and link its people. Most of the country’s population lives within 80 miles (130 km) of Georgetown and it is important to link these people together. The only thing keeping Georgetown apart from West Bank Demerara was the Demerara River. The government decided to construct a floating bridge to accommodate growing business and trade across Guyana.

Management     

The Demerara Harbour Bridge is managed by the Management and Monitoring Unit, Demerara Harbour Bridge Rehabilitation Project (MMU-DHB-RP), a subsidiary of the Ministry of Public Works(MPW). MMU, however functions independently of the MPW, and maintains a full staff responsible for maintenance, management, construction and operation. MMU also maintains financial independence based on revenue earned from tolls (vehicle and water-borne vessels). They have a staff of about 60 people. The schedule of closures to road traffic, alert messages for the public, details on the history of the bridge, etc. is available on the official Harbour Bridge website.
