30,000 cubic metres of concrete needed for the pre-construction of the new Verkkosaari district<\/h1>\n

The construction of the northern part of Verkkosaari is the largest piece-work contract with a total price in the history of main contractor GRK Infra. About 30,000 cubic metres of concrete are needed for the pile slabs and the different engineering structures. The quality of the concrete is assured in Sweco\u2019s laboratory with hundreds of compression strength tests.<\/p>\n

The City of Helsinki has commissioned the construction of a new residential area into the northern part of Verkkosaari, to where about 3,600 residents are expected to move in 2024. GRK Infra acts as the main pre-construction contractor of the 70-million-euro project. The size of the area is 13 hectares.<\/span>\u00a0<\/span><\/p>\n

\u201cIn addition to streets and municipal technology, a massive shore wall will be built into the area, as residential construction spreads out onto the sea,\u201d says GRK Infra Oy\u2019s construction site manager\u00a0<\/span>Risto Laakkonen<\/span><\/strong>. The pre-construction also includes the removal of contaminated soil and sea dredging. \u201dWe expect to be ready by autumn 2022.\u201d<\/span>\u00a0<\/span><\/p>\n

The construction of Verkkosaari is the largest piece-work infrastructure contract with a total price in the history of GRK. About 30,000 cubic metres of concrete is needed, two thirds of which are used for cast pile slabs supported by drilled steel piles. In addition, concrete is needed for different engineered structures such as shore and retaining walls. \u201dThere will definitely be hundreds of concrete compression strength tests!\u201d Laakkonen says.<\/span>\u00a0<\/span><\/p>\n

Ruskon Betoni manufactures the test pieces of concrete and delivers them to Sweco\u2019s laboratory. The compression strength of the concrete is tested within 28 days from the manufacturing of the test piece, and the result is sent to the customer the same day.<\/span>\u00a0<\/span><\/p>\n

\u201dHardened pieces of concrete will be subjected to an accredited compression strength test according to the SFS-EN 12390-3 standard, which ensures the concrete\u2019s compliance with the specified structural strength,\u201d says\u00a0<\/span>Tuomo Rimpil\u00e4inen\u00a0<\/span><\/strong>of Sweco.<\/span>\u00a0<\/span><\/p>\n

Unwavering cooperation in concrete quality monitoring<\/h4>\n

The construction of Verkkosaari has been preceded by long-term cooperation between GRK and Sweco in the metropolitan area\u2019s infrastructure projects.<\/span>\u00a0<\/span><\/p>\n

\u201dDuring the last five years, we have needed concrete quality monitoring for example\u00a0<\/span>in the City of Helsinki\u2019s contract\u00a0<\/span>at Pasila railway yard and in large infrastructure contracts of the Finnish Transport Infrastructure Agency,\u201d Laakkonen reports. \u201cWith the smaller contracts included, the number of tested concrete pieces rises to the hundreds.\u201d<\/span>\u00a0<\/span><\/p>\n

Laakkonen appreciates his long-term cooperation partner for independent concrete quality monitoring and smooth services. \u201cThe testing of concrete is based on infrastructure construction guidelines and quality assurance<\/a> requirements. I always receive clear, timely and appropriate documentation from Sweco.\u201d<\/span><\/p>\n\t\t<\/div>\n\t<\/div>\n<\/div>\n<\/section>\n","protected":false},"excerpt":{"rendered":"
