its about time...

Muscat Muncipality has finally decided to come to terms to deal with waiting work needed on the roads that had been damaged in the Gonu incident that hit the Sultanate of Oman, not too long ago.

Along the named projects to be worked upon are the dual carriageway of Wadi Addai/Amerat; and the service roads of Bowshar; Amerat; Quriyat; Seeb; Muttrah; Qurum beach road that links between Qurum/Sarooj; development of the Seeb sea front road; and rehabilitation of the Muttrah Corniche road.

All the new plans and drawings have been redesigned with consideration to anti-flood resistance measures in such cases as the past storm incident in Oman. All new work should start sometime around the month of September of 2007.

Contract soon for Qurum beach road reconstruction
2 new bridges to span tidal lagoons
By Conrad Prabhu
MUSCAT — A contract for the reconstruction of the Qurum-Al Sarooj beach road, which was partly swept away by flood waters during the recent adverse weather conditions in Oman, is expected to be awarded by Muscat Municipality in the coming weeks. A number of leading contractors, including Nagarjuna Construction Company (NCC), Galfar Engineering and Contracting and Consolidated Contractors Company (CCC), are in the race for the contract. The beach road, which overlooks the Gulf of Oman, has been a popular attraction for families and cityfolk in general, particularly on weekends and holidays.

Besides providing easy access to the entire stretch of the Qurum beach, the road has the appeal of a boulevard attracting joggers and strollers alike. As part of the planned improvements to the badly damaged stretch, two new bridges will be constructed across tidal lagoons that were created as a result of the June floods. One is a five-span 150-metre long bridge, while the other is a single-span 30-metre-long bridge. These bridges will replace the drainage culverts that proved ineffective in channelling the huge amounts of flood water generated by last June’s adverse weather.

To ensure that the bridges can withstand future flood events, construction of the structures will involve piled foundations approximately 30 metres deep. Abutments and piers will be reinforced concrete and located in tidal water. Besides, the reinforced concrete decks will be supported on precast post-tensioned concrete beams. Furthermore, embankments on the seaside will be protected against wave and flood action with the use of armoured rock and rock rivetments.

Officials say the robust measures are necessary to prevent any repeat of the damage that flood waters have caused to the beachfront stretch in the past. Severe flooding in 1981 caused two major breaches in the sand bar across which the road now lies. Two significant breaches also appeared on the same stretch during the recent floods in June. With a construction timeframe of 10 months, the reconstructed beach road is expected to be completed by the third quarter of next year.

Wadi Adai-Al Amerat road to be rebuilt along new alignment
p Envisaged route planned to be flood-proof
p Interchange near Al Nahdha Hospital
p Two major bridges to span wadi
By Conrad Prabhu
MUSCAT — The Wadi Adai - Al Amerat carriageway, which was almost entirely wrecked by raging floodwaters during last June’s adverse weather conditions in the Sultanate, will be rebuilt along a completely new alignment, deviating away its current route that runs along Wadi Adai’s flood-prone course. A tender for the reconstruction of this key road, which currently provides the only land link with Al Amerat and Qurayat beyond, has now been floated by Muscat Municipality. It calls for the construction of a 7.1 kilometre-long dual carriageway from near Al Nahdha Hospital in Wadi Adai to a point just before the Graveyard Roundabout at Al Amerat.

The new, streamlined alignment cuts through the surrounding hilly terrain at a safe distance from the route of the wadi. It intersects the wadi at only two points where major bridges will be built. This is designed to ensure that, while providing connectivity to existing settlements along the route, the new road will essentially be flood-proof. Several other bridges will also be built elsewhere along the route of the new alignment. In all, around seven bridges are envisaged, of a total length of around 900 metres. Major I-girder bridges, with pier heights of 20 to 25 metres, are planned at the two points where the new road will span the wadi.

Another key feature of the project involves the construction of an interchange near Al Nahdha Hospital. This would eliminate present peak-hour traffic snarls at the Wadi Adai roundabout, say officials. Although a mere 7.1-kilometres, the project promises to be one of the most technically challenging to be undertaken in the Sultanate in recent years. Given the ruggedness of the terrain through which the new alignment will run, accessibility will be a major constraint for the selected contractor. Besides, the project will rank among the most expensive infrastructure undertakings of its kind.

Project costs are estimated at between RO 80-100 million, primarily due to the huge volumes of excavation work necessary to be carried out. The selected contractor will be required to excavate and transport some 10 million cubic metres of hard rock and earth. An estimated 150,000 metric tons of concrete and 37,000 metric tons of steel, prices of which are now hovering at record world highs, will be required for the project. Significantly, reconstruction of the Wadi Adai-Al Amerat road will be executed on a fast-track basis. With Muscat Municipality stipulating an 18-months construction timeframe, the project is targeted for completion by the second quarter of 2009. Parsons International and Company LLC are consultants for the project. "
