CSDA Contractor Slices Through 2,000 Tons of Concrete at Texas Port

Diamond Wire Sawing Tackles Wind, Waves and Weather The Port of Corpus Christi is the nation’s number one exporter of crude oil and port officials plan to further that dominance by utilizing an additional 250 acres of land on nearby Harbor Island. This new project will allow larger oil tankers to dock by increasing the depth of the shipping channel. Harbor Island is located along the northeast perimeter of Corpus Christi Bay and within the city limits of Aransas Pass and Port Aransas in Texas. Work has already begun to deepen the channel from a maximum depth of 40 feet to depths of up to 54 feet, making it the first port in Texas with a channel deeper than 50 feet. This project is being managed in part by the U.S. Army Corps of Engineers and will cost over $325 million. As part of this work, a new desalination facility needs to be constructed to provide non-potable water to the industrial sector, as well as a crude oil export facility. Existing structures on Harbor Island first needed to be demolished, including three loading docks, six concrete mooring structures over water and on land, as well as several concrete and metal buildings, concrete light poles, concrete foundations and miscellaneous concrete and debris strewn across the bottom of the channel—remnants of damage caused by Hurricane Harvey in 2017. General Contractor Derrick Construction was tasked with this project and turned to CSDA member Holes Incorporated to handle the demolition, rigging and hauling away of massive amounts of concrete and metal. Holes won the job by offering turn-key demolition services. Competing bids did not offer full services, nor did they have the reputation of successfully completing difficult projects like this one. With 47 years of experience, Derrick Construction knew that the Holes operators could be trusted to get this job done right. Work on the demolition of the existing structures began in January 2019, one week after the general contractor arrived onsite. The first step was to break and haul out a large stockpile of concrete believed to be old tank foundations—about 500 cubic yards of material. Next, the concrete mooring structures needed to be removed. Two were located on land and five over water, making removal challenging. The two mooring structures on land measured 20-feet by 17-feet and 6-feet thick sitting on...

Protecting the Environment one cut at a time

A main highway in New Zealand has been undergoing a multi-year improvement and expansion project, and in winter 2019, a section with over-water bridges in New Zealand needed to be expanded. It was determined there was only one way to complete the job quickly and safely.Concrete cutting with diamond tools would allow for pre-planning of cut sections and a fast, clean removal of roadway sections. As this series of bridges and roads also spanned a tidal creek, it was imperative that no debris or slurry be allowed to fall into the creek, and also that no fly rock would strike vehicle traffic. The SH1 Southern Motorway on the North Island of New Zealand is part of State Highway 1, the longest and most significant road in the country. SH1 runs for 2,033 km (1,263 miles) and is primarily a two-lane single carriageway. It is an essential part of Auckland’s transport network and is the primary route between Auckland, Hamilton and Tauranga. The Southern Corridor Improvements Project, which will cost $268 million (USD$183 million) and runs for over four years, covers the stretch of SH1 from the SH20/SH1 connection at Manukau down to Papakura in the south. CSDA member A1 Kiwi Cutters & Drillers Ltd. of Auckland was selected as the cutting contractor on the Southern Corridor Improvements project by the general contractor and the New Zealand Government. Roughly four months of planning took place before any work commenced, which contributed to the successful outcome of the project. The entire project was to convert a two-lane section of motorway to a three-lane by constructing a temporary bridge, widening some existing bridges, removing other existing bridges and building a new wider bridge. The temporary bridge was constructed first to allow for southbound traffic to be diverted while the northbound traffic was diverted to the old southbound lanes. Then, the existing northbound bridge was removed, and a new wider bridge was constructed in its place. Both north and southbound traffic was then diverted to the new bridge while the old southbound and temporary bridges were removed to allow for construction of the new, wider southbound bridge. A1 Kiwi Cutters was tasked with removing the existing southbound bridge and temporary bridge, including head stock and bridge beams. Concrete cutting was determined to be the best option for removing the old bridges primarily for...

Contractors use diamond wire to cut and remove large sections of heavily-reinforced concrete on piers, dams, bridge sections and in areas where work space is restricted. Of these restricted work areas, none present more challenges than when the structure is underwater.
