Summary5201094 summary Theme Building for energy Building for energy (pp. 4 - 8) Although it is no longer growing, demand for energy in the Netherlands continues to be large. The majority of electricity is gener- ated inside the country. The sources include natural gas, coal, waste, wind and hydro power. In recent years there has been signifi- cant demand for renewable power genera- tion. Many of the existing power stations are at the end of their economic lifetimes. These are some of the reasons why many new energy projects are being implemented in the Netherlands at the moment. Largest turbine foundation in the world (pp. 10 - 14) E.ON is currently building a new coal-fired power station on Rotterdam's Maasvlakte. The heart of the power station consists of a system of five coupled turbines. These tur- bines generate dynamic loads. A solid struc- ture is needed to support them: the turbine foundation. Its dimensions of 58 x 18 x 3.5 metres make it one of the largest in the world. Construction pit with temporary barrette piles (pp. 16 - 21) Electrabel is constructing a new power sta- tion on the Maasvlakte in Rotterdam. It is an ultramodern facility that can be fuelled par- tially by coal and partially by biomass. The cooling water system is an important part of the project. During the construction of this system the quay wall adjacent to the con- struction pit was temporarily supported by barrette piles. Fly ash silo with inverted cone (pp. 22 - 25) In Electrabel's new power station the flue gases produced during combustion are cleaned in a number of steps. At the end of the process they meet very stringent require- ments. One of the first steps is the electro- static filtration of the larger particles: the fly ash. The fly ash is stored in a silo and reused, in the concrete industry and elsewhere. LNG tanks subject to special loads (pp. 26 - 31) As of September 2011 the Port of Rotterdam will have a large liquefied natural gas storage and handling terminal: the GATE (Gas Access to Europe) terminal. The project encompass- es the construction of two jetties, installa- tions to regasify the LNG, and three storage tanks. The tanks were discussed briefly in Cement 2009/5. This article looks at them in greater detail. From waste to energy (pp. 32 - 37) In Roosendaal alongside the A17 motorway work is presently being done on a new waste processing installation for SITA: BAVIRO. The installation is intended to enlarge and replace the current one. This article describes some special structures and the way that the different parties involved in the design and construction work together. Greenmills, a sustainable project (pp. 38 - 43) Orgaworld is currently building a new diges- tion and water treatment plant called Green- mills in the Westpoort docks in Amsterdam. It is the first construction phase of a sustain- able project that will ultimately also have a composting facility and a bio-ethanol plant. Borgharen hydro power station (pp. 44 - 48) The wishes and ambitions to produce an ever greater share of power needs from renewable resources are keeping the pos- sibilities for using hydro power to generate electricity at the front of people's thinking. Tidal power stations, river power stations and small-scale micro power stations are presently being studied. This article explains the plans for a hydro power station at the Borgharen barrage. Concrete monopile (pp. 50 - 53) A driven steel monopile is frequently used for the foundations of an offshore wind tur- bine. These piles are 4 to 5 metres in diam- eter and 40 to 60 m long. From the water they are driven about 30 metres into the seabed. Ballast Nedam in collaboration with MT Piling has developed the drilled concrete monopile as an alternative. Outside the theme Attractive serenity (pp. 62 - 64) Tall trees and banks surround Heimolen Cemetery on three sides, so that the site is barely visible from the motorway. This cem- etery in the Belgian town of Sint-Niklaas has been extended since 2008 and it now has a crematorium and a reception building. In 2009 the design, by Claus & Kaan Architect- en, won the Dutch Concrete Prize in the`con- crete and society'category. The new designer (2) (pp. 65 - 67) Design safety in the Netherlands is at risk. Fees are under enormous pressure and designers are consequently adapting their activities out of sheer necessity. Other par- ties are taking over tasks. Clients are pay- ing for the miscommunication and mis- takes that are the upshot. It is high time to stop cutting corners in the discipline and to highlight the added value that the disci- pline creates. Ellipses grace the Utrecht skyline (pp. 68 - 75) The finishing touches are currently being put to a special Rabobank Nederland office block in Croeselaan, Utrecht. The building is close to Utrecht's Central Station and the Jaar- beurs exhibition centre, at the front of the existing Rabobank Nederland office com- plex. The elliptical glass skyscraper can be seen from the train and from as far away as the A12 motorway. Sloping surfaces (pp. 76 - 79) Lausanne University of Technology was recently enriched by a new and striking building: the Rolex Learning Center. Besides providing accommodation for various librar- ies, student workplaces and cultural activi- ties, the building also has an iconic gateway to the campus. The most important struc- tural footprint - enormous flowing concrete spans lacking any detail whatsoever. School in 3D (pp. 80 - 83) A new school complex is under construc- tion in Boerhaavelaan, Haarlem. LJC2 is a community school for preparatory second- ary vocational education, and is scheduled to open for the new 2010/2011 school year. Modelling this building entirely in 3D saved time, resolved installation issues, and avoided fitting problems on the build- ing site and in the factory. Walls and finite element method (pp. 84 - 88) For many years design calculations for wall elements have been based on a finite ele- ment method. This method is attractive because it takes relatively little time and much less reinforcement is needed than with other methods. However, there is also a great deal of resistance - the software provides little insight and sometimes it produces implausible results. Now that Eurocode 2 explicitly permits this method, auditing organisations have little scope for setting additional requirements. There is therefore every reason for a detailed analysis. Hollow wall system in exposed concrete (Cementonline / pp. 89) From the end of 2010 the drinking water in the Bommelerwaard will be considerably softer. The complete renovation of a pump- ing station in Waardenburg is among the measures being taken to do this. The archi- tect wanted a concrete load-bearing struc- ture for the production building. The inside of this building had to be exposed concrete. Explosions in tunnels (Cementonline / pp. 89) There are currently no regulations for design- ing and evaluating tunnels through which hazardous substances are transported. There is need for an understanding of the loads that can occur in the event of an explosion and its implications for the tunnel structure. This is one of the reasons why Delft Cluster has conducted a detailed investigation. If you would like a whole article from Cement translated, why not let us arrange it for you?
