The total thickness of the slab is ______ cm, to be partially lightened (according to the design) with recycled plastic modules, such as “U-Bahn Beton®” from the Daliform Group, with an extended form of 120 cm with an isosceles trapezoid section with a max base of 40 cm height 20 cm, with a length that can be divided in sub-multiples of 20 cm and joinable in line together to overlap the fi nal edge; supplied with 24 truncated-pyramidal feet that are 4 cm in height, resting on the horizontal support for the formation of the thickness of the soffi t suitably reinforced with welded mesh, 10 x 10 cm, with a Ø 5 mm steel rod. This includes the supply and positioning of the “U-Bahn Beton®” modules to be placed in parallel, suitably distanced rows to form continuous joists between beams that are closed on their respective fi nal tunnels with closing panels; a welded mesh 20 x 20 cm - Ø 5 mm is placed above the formworks. The upper and lower reinforcements will be connected, in the joists, with vertical C-shaped steel hooks min Ø 8 mm placed at a centre distance of 30 cm along the joist axis. Also included is the supply and casting of the concrete needed to create the slab (in the full and lightened zone), fi lling and vibrating fi rst the part under the formworks until completely covering the feet of the “U-Bahn Beton®” (no further) (minimum resistance class C25/30, fl uidity class S5 and diameter of aggregates suitable, in order to avoid phenomenon like “segregation”), the casting will then continue until the slab is completed as soon as the fi rst layer starts to set (in this second phase, a fl uidity class different than the previous one is permitted) until the slab is completed with the formation of a min 4 cm layer. The horizontal support formwork, welded mesh, reinforcement bars, beam cages and vertical C-shaped connectors will be entered somewhere else. The “U-Bahn Beton®” modules, must be produced in “ALAPLEN® CV30”, must be safe to walk on and certifi ed with a resistance characteristic of 150 kg in the weakest point on an 8 x 8 cm support; they must not release any polluting substances and must have an Environmental Conformity Certifi cate and be produced by a company using an Integrated Management system (ISO 9001, ISO 14001, OHSAS 18001, SA 8000). The executive design of the lightened slabs must have graphs and calculations provided by the company supplying the “U-Bahn Beton®” modules that must exhibit technical sheet and safety sheet for the product and for “ALAPLEN® CV30” grain texture and that must also exhibit the product certifi cate approved by a EOTA member (European Organisation for Technical Approvals). The cost for the creation of holes with the dimensions and sections foreseen by the architectural drawings is also included, the price also includes and covers all costs for providing the fi nished work in a workmanlike manner; it does not include the supply and positioning of the horizontal formwork that supports the slab and accessories, the lattice and the metal reinforcement, which will be entered separately. cost Euro/m2. ____________________ Logistics - pallet capacity Tractor (8.20x2.45) Trailer (6.20x2.45) Tractor+ Trailer type “BIG” (8.40+7.20x2.45) Semi-trailer (13.60x2.45) 20 feet container 40 feet container 12 10 12 + 12 22 11* 18* MEANS OF TRANSPORT NO.
