B.I. CONSTRUCTION WORKS

B.I.1. INFRASTRUCTURE WORKS

B.I.1.a. LAYER OF WHITE GRAVEL PARTICLES EMBEDDED IN A COLORLESS RESIN FINISH APPLIED ON A CONCRETE SUPPORT

The previously executed concrete support (by the EXPO S.p.A.) will be covered with a layer of white gravel particles embedded in a resin finish, forming a non-skidding layer.

The base layer (concrete) has to be well dried before applying the primer and the gravel particles. The applied resin-binder, the primer will have a maximum 15mm thickness, including the gravel particles. The white gravel particles, with sizes between 4-8mm will be polished until the edges become rounded, they will be cleaned from the excess dust and dried at a relative humidity of maximum 4%.

B.I.1.b. LAYER OF WHITE GRAVEL PARTICLES EMBEDDED IN A COLORLESS RESIN FINISH APPLIED ON THE SURFACE OF THE ECOLOGICAL POND + GRATE FOR THE DRAIN + COVER FOR THE WATER CONTROL STATION

The layer will be applied on the surface of the ecological pond, previously executed by the EXPO S.P.A. The technological process and the necessary materials will be made according to chapter B.I.1.a.

Aluminium edge profiles will be used (almost invisible profiles) at the joints between the horizontal and vertical surfaces.

The constructor will have the task to perform the arrangement of the ecological pond, the necessary materials and maintenance will be presented in the chapter B.III.8. Arrangement of the ecological pond.

The grate will be placed at the perimetral drain system of the pond and will be made of 200mm stainless steel.

The cover for the water control station will be made out of 50x10mm iron strips placed on two directions, covered with a thick iron sheet, which becomes support for the layer of white gravel particles embedded in a colourless resin film, technological procedure described in chapter B.I.1.a. On top of this cover an X20 vacuum tube solar panel will be mounted.

For details check de architectural drawings A03.Ground floor plan, A06.Longitudinal Section A-A`, A07.Cross Section B-B` and detail D12.

B.I.1.c. CONCRETE BLOCKS

Concrete blocks: 32 pieces with the dimensions of 80x40cm and 32cm height and 6 pieces with the dimensions of 130x40cm and 32 cm height.

The concrete composition is C20/25, CEMIIA-S42.5N, CI0 2%, D16, S3.

At the 80x40cm blocks plastic or wooden elements will be placed in the encasement, elements that will be removed afterwards, in order to create spaces for the recessed light fixtures. Plastic tubes will be placed in the concrete for the necessary electric cables.

The concrete blocks will receive the same resin finish with layer of white gravel particles, the technological procedure already described in the chapter B.I.1.a, so that the concrete blocks and the ecological ponds surface will have a unitary aesthetic aspect.

For details check the architecture section, drawing A08`Location plan and section for the concrete blocks.

B.I.1.d. WALL SEPARATING THE POOLS

A 10cm thick wall will be poured, representing the separation between the two pools placed on different heights, for details check the drawing A03. Ground floor plan.

The concrete composition is C20/25, CEMIIA-S42.5N, CI0 2%, D16, S3.

B.I.1.e. LEVELING SCREED FROM LIGHTWEIGHT CONCRETE FOR THE GROUND FLOOR

A light concrete with sand layer will be poured, power float (helicopter) treated, 5,2cm thick over the concrete slab for levelling.

For details check the architectural drawings (DT1a, DT2a, DT3a, DT4a, DT5a, and DT8c)

B.I.2. OVERSTRUCTURE WORKS

WOODEN CONSTRUCTION ELEMENTS

Materials.

The wooden structural elements from the ground floor, upper floor and also the framework will be made of first class of exploitation wood characterized by a humidity of the wood material correspondent to a temperature of 20±2 °C and an air relative humidity of ≤65%.

In case of the wooden construction elements operated in Class 1, the wood balance humidity will not exceed 12%. If during installation the wood material has a higher humidity (but no more than 12%) and there is no possibility to be dried on site, constructive measures will be applied, protective measures concerning the ventilation of the structural elements without introducing dangerous alterations in the structural resistance or the increase of the value of the sectioned efforts.

Wooden species and assortments.

The wooden material for the structures will be chosen accordingly with the construction exploitation class and the value and nature of the efforts involved.

The wooden structures will be made as follows:

·  For the ground floor (the interior wooden panels, the closure vertical panels and the ceiling beams over the ground floor) will be used GL32 stratified wood, according to the EN1194 European standard.

·  For the first floor structural wooden elements (circular wood logs having a 25cm diameter by resinous wood essence, forming the split floor above the first level, but also the exterior wall structure and the wooden elements that form the roof structure) will use solid pine wood or by case, another wood that assures a minimal bending resistance at 24N/mm2

The wooden material used for the pavilion, as structural elements of resistance will be divided in three categories:

I – Elements subject to stretching and bending: the main wooden beams of the split floor above the first floor (15x80cm);

II – Elements subject to compression and bending: the beams of the framework, the laminated wooden beams that form the ground floor walls (8x40cm), the beams that form the first floors house structure, circular wood logs (25cmdiameter);

III – Secondary elements: secondary beams that form the structure of the ceiling above the ground floor (9x25cm).

Quality tests.

The verification of the sizes of all wooden elements will be made with ordinary measuring devices. The acceptable deviation from the flatness, measured with a tape on a length of 3.0 m is 5 mm along the maximum slope line.

The bolts and the arbores will be mounted in holes prepared in advance by pre-drilling.

Bar-type joining elements (nails, hooks and screws) have a plastic behaviour. It is recommended that the bar penetration to be increased in the wooden element, in order to prevent the risk of wrenching. The use of rods with profiles is also recommended (with spiral channels, with fingers).

JOINTS WITH METAL RODS

The joints referred to in the present chapter are the ones that connect the main beams with the secondary beams from the ceiling over the ground floor, the mounting elements of the 25 cm diameter circular logs that form the ceiling over the upper floor, the main holding elements of the laminated wood beams that form the walls of the ground floor volume.

For more details check the S14 structure drawings: Structural details part 1 and S15: Structural details part 2.

The minimal thickness of the thinnest element joined with nails must be at least of 4d, to prevent cracking when nails are inserted.

In order to take into consideration the shearing section, the nail must be inserted in the respective element at least 3.5d (effective lengths, without the tip of the nail of 1.5d);

The bolts will be made of OB37 concrete iron, with head and screw nut having the diameters of the smooth concrete iron used in constructions (12…16 mm, according to the joints fabrication details in the structure drawings S14 and S15);

In the case in which the bolts diameters are not specified in the drawings, they will be chosen in the regular way (1/30…1/40) l, where l is the thickness of the joint package, but minimum 12 mm.

The holes for the bolts will be drilled by the rule: dhole= dbar+1mm, and the holes for the arbors and the dowels will be drilled by the rule: dhole = dtbar – (0, 8 ~ 1,0)mm;

The bolts, the screws and the arbores are placed on an even number of longitudinal lines, to prevent placing a row of bars in the weak central part of the wood.

The iron elements used for joining are protected by priming with a paint made of double boiled linseed oil and minimum lead that must cover the entire surface of the metal element.

Before the anticorrosive protection is applied, the surface of the metal must be cleaned of the lamination layer (scum) and other impurities (dust, oxides, greases) and it must be completely dry.

WOOD FIREPROOFING MEASURES

The wood used to build the pavilion structure will be fireproofed in controlled conditions and transported afterwards on site.

The fireproofing supplier is obliged to certify the quality of the accomplished fireproofing by certified tests from authorized laboratories.
