Underwater Building Plans Advance in Virginia and Macau

Underwater Construction ContractorUnderwater construction became possible ever since technology like that of uccdive.com allowed people to build infrastructure below the ground and sea level.

In Virginia, officials of the Chesapeake Bay Bridge-Tunnel have selected three bids for the construction of a new parallel tunnel on July 15, The Virginian-Pilot reported.

On the other side of the globe, Macau officials are seeking a study for the viability of building underwater tunnels, to according Macauhub.

Public Bidding

The Chesapeake Bay Bridge-Tunnel officials reworked the project after tenders for the plan exceeded the intended budget. Three companies originally floated a proposal worth more than $1 billion, exceeding the estimated $724.4 million allocation, which led officials to redo the project’s blueprint to save on costs.

On July 15, officials opened reworked bids that were lower than the previous tenders, although they still came in higher than the estimated cost of the project.

Regarding the project changes to reduce costs, CBBT Executive Director Jeff Holland will provide the specific details on the revisions on July 27. Work on the project is expected to begin in 2017 and completion is slated for 2020 at the earliest.

Studying Underwater Tunnels

In Macau, government officials appointed Chinese company CCCC Highway Consultants Co. Ltd. Macau Branch to conduct a feasibility study of the underwater construction of two tunnels near the Nobre de Carvalho Bridge.

The Directorate of Land, Public Works and Transport chose the company after it proposed the lowest price for the study at US$902,500. The study aims to determine the possibility of implementing the initial design of the project.

The two tunnels would each have a minimum of two lanes, with the tunnels measuring a combined length of 2,400 meters, provided that they will connect the areas of new landfills in the Macau Peninsula and Taipa Island.

The studio faces a deadline of completion within 260 days and a draft report is expected to be released by the middle of 2017.
