            Project
          
        
        
          Along the A20 highway at Maassluis in the Netherlands
        
        
          a new innovative international head office, R&D
        
        
          centre and production hall for the Lely group has been
        
        
          implemented. Lely is a Dutch family business that offers
        
        
          robotic products and services to the agricultural sector.
        
        
          The new building, designed by Consort Architects, is
        
        
          expected to be completed by mid-2013. The project
        
        
          includes a warehouse with parking space on the roof
        
        
          and three connecting office buildings with showrooms,
        
        
          conference rooms and a company restaurant.
        
        
          The project illustrates the power of integrated design in
        
        
          a special way. From the crawl space up to the parking
        
        
          deck, at every level of the building it is evident that the
        
        
          various disciplines in the design and construction team
        
        
          have worked together closely for the best, most durable
        
        
          and fastest results.
        
        
          Lely has high sustainability ambitions for this project,
        
        
          ranging from the integration of the total complex into the
        
        
          existing area to putting up bat- and bird-nest housings
        
        
          on the factory hall. The far-reaching commitment
        
        
          to sustainability was awarded by the DGBC with
        
        
          the highest BREEAM certificate (‘Outstanding’, the
        
        
          maximum 5 stars) for the design of the production
        
        
          hall. This level has not previously been achieved on
        
        
          the European mainland by a building with an industrial
        
        
          function. The Office buildings achieved the designation
        
        
          ‘Excellent’ (4 stars).
        
        
          
            Design
          
        
        
          The warehouse (22,500 m
        
        
          2
        
        
          ) was designed as a
        
        
          “platform building”, eliminating the need for expensive
        
        
          lowered loading docks with a pile supported concrete
        
        
          floor. The elevated business floor, consisting of hollow
        
        
          core slabs, was completely prefabricated, just like
        
        
          the rest of the building. This enabled a very high
        
        
          construction rate which can be phased “horizontally”.
        
        
          While on one side the pilecaps were still being placed,
        
        
          the roof sheets were already being mounted on the
        
        
          other side of the building.
        
        
          The prefabricated pilecaps were carefully engineered
        
        
          with simple connections of the cap to the foundation
        
        
          piles, foundation beams, hollow core slabs and
        
        
          columns. The pilecap dimensions of 2.4 m by
        
        
          2.4 m were not just determined by the structural
        
        
          considerations, they are also a multiple of the width of
        
        
          the connecting hollow core slabs. This design has led to
        
        
          a quick assembly process.
        
        
          The grid distances of the concrete columns in the
        
        
          industrial building were tailored to the wishes of the
        
        
          client. After an extensive study of roof variants, a
        
        
          structure with TT-slabs spanning 20 m was chosen.
        
        
          With a shorter span (10.8 m) of the prestressed
        
        
          roofbeams the number of columns on the production
        
        
          floor was sufficiently minimised. The columns are
        
        
          sandwiched into the prefabricated pilecaps at the
        
        
          bottom. Each column plays a part in the stability of the
        
        
          hall; there is no bracing.
        
        
          The office building adjacent to the warehouse is made
        
        
          up of a steel main supporting structure with hollow core
        
        
          slabs in between. The steel trusses are raised above
        
        
          ground level so that the freight cars can pass under the
        
        
          building. The diagonals, columns and connections in the
        
        
          trusses were designed with close consultation between
        
        
          the architect and the structural engineer. The trusses,
        
        
          along with the steel staircases, provide the stability of
        
        
          the buildings. A saving of the total amount of material
        
        
          used was obtained through the use of trusses as the
        
        
          main supporting structure.
        
        
          
            Calculations
          
        
        
          Scia Engineer software was used for the main
        
        
          calculations of the structure. With Scia Engineer it is
        
        
          possible to create fantastic 3D models. However, we
        
        
          have chosen to make the calculations of this project in
        
        
          such a way that the full structure could be represented
        
        
          with simple 2D models of the structural components.
        
        
          The power of Scia Engineer is that it is possible to
        
        
          calculate the entire building with a few 2D models of the
        
        
          trusses and beams. With this, we were able to present
        
        
          the structure in a clear and concise manner in the
        
        
          calculations.
