Doka Formwork Solutions: New Stadium of Tottenham Hotspur (latest news)

NEWS: May 10, 2017 Spurs get green light for stadium capacity increase

Full screenTottenham Hotspur new stadium Night image stadium exteriorThe capacity of Tottenham Hotspur’s new £800m stadium is to grow after an application to increase its size was accepted by Haringey Council.  The club’s initial planning application was for a 61,461-seater stadium but design changes to the roof and seating layout has meant that an extra 98 seats can be installed in the ground. After submitting an amended planning document to Haringey Council the changes have now been given the go-ahead by its planning officers.A club statement said: “Improved seating layout design has meant that we have been able to increase seating in several areas of the stadium. This will now see our official capacity rise to a total of 61,559.” According to Spurs, the biggest change will be in the stadium’s South stand, which under the new plans will be able to accommodate 17,500 spectators, an increase of 500 from original plans.

How to build a hydroelectric plant at temperature – 40 º C ?

UK, December 16, 2016.-  In the construction of the 824 MW Muskrat Falls hydroelectric power station in Labrador, Canada, extreme cold is a particular challenge. Temperatures as low as -40°C are not uncommon at the site. These conditions require accuracy and expertise at the highest level in terms of planning and implementation. To meet these challenges, Doka is providing the formwork solutions and is setting new standards with its innovative Concremote system. The Muskrat Falls Hydroelectric Generating Facility is located on the Lower Churchill River in the province of Labrador. Once operational, it will power homes and businesses across the Canadian provinces of Newfoundland and Labrador. The hydroelectric power plant consists of a generating plant, four turbines, a central dam and adjoining north and south dams. In the power house there are four power plant units, each of which has a 206 MW Kaplan turbine, an inlet, a half spiral and an intake manifold. A total of five spillways are being built to prevent flooding. The construction firm Astaldi Canada has selected Doka as its reliable partner for formwork. The client’s prerequisite for awarding the contract was 100% documentation, high-precision and zero-fault tolerance.

‘New but Old’ Maturity Method of Measuring Concrete Strength (and Part 2)

The procedure for estimating the in-place strength requires measuring the in-place maturity.  This is achieved by installing sensors at locations in the structure that are critical in terms of exposure conditions and structural requirements.  The importance of this step cannot be over emphasised when the strength estimates are being used for the timing the start of critical construction operations. The October 5th Doka UK published the second part of this analysis: Maturity Method of Measuring Concrete Strength

The first part of this analysis published here on 27 September. We invite you to read it first.

UK, 5 october, 2016.-  The procedure for estimating the in-place strength requires measuring the in-place maturity.  This is achieved by installing sensors at locations in the structure that are critical in terms of exposure conditions and structural requirements.  The importance of this step cannot be over emphasised when the strength estimates are being used for the timing the start of critical construction operations.

Doka’s Concremote product and data driven service conforms to all of these International Standards and the Concremote sensors measure simultaneously the in-place concrete and ambient temperatures and time and compares this real-time data against a known calibrated concrete mix results and raises real time alerts when the required in-place target concrete strength is reached. Facilitating the optimization of on-site production activities. Typical data feeds from the Concremote monitoring service are:
