4.1.2.2.2 Mortars for Mansory

The water and sand for the preparation of the dough must meet the requirements and technical characteristics referred to in the articles "Materials in General" and "Water, Limes, Cements and Cement Agglomerations". The use of ready-made pre-mixed and pre-mixed mortars is permitted, provided that each supply is accompanied by a supplier's declaration certifying the group of mortar, the type and quantity of binders and any additives. If the type of mortar does not match within those indicated below, the supplier must certify with official tests also the strength characteristics of the mortar itself. The procedures for determining the compressive strength of mortars are set out in Ministerial Decree 13-9-1993.

Types of mortar and their classes are defined in relation to the composition in volume;

mortars of different proportions in composition also packaged with additives, previously tested, can be considered equivalent to those indicated if their average compressive strength is not lower than the values referred to in Ministerial Decree 20-11-1987, n. 103.

- 24 -

1. Aggregates for cementitious conglomerates, natural and crushing, must consist of non-frosty and non-friable elements, free of organic, silty and clayey substances, etc., in proportions not harmful to the hardening of the conglomerate or to the preservation of the reinforcements. Gravel or crushed stone must have maximum dimensions commensurate with the geometric characteristics of the carpentry of the casting and the size of the reinforcements. The sand for mortars must be free of organic, earthy or clayey substances, and have a maximum grain size of 2 mm for masonry in general, 1 mm for plasters and parameter masonry or in cutting stone.

2. Additives for cementitious mixtures are classified as follows: fluidifiers;

aerants; retardants; accelerants; fluidifiers-aerants; fluidifiers-retardants;

fluidifiers- accelerants; antifreeze-superfluidifying agents.

3. Cement conglomerates for reinforced concrete structures must comply with all the requirements of Ministerial Decree 14-2-1992 and related explanatory circulars.

4.1.2.2.4 Brick and concrete elements

The artificial resistant elements to be used in the masonry (brick and concrete elements) can be made of normal brick, lightened brick paste, normal concrete, lightened concrete.

When used in the construction of load-bearing masonry, they must meet the requirements contained in Ministerial Decree 20-11-1987 (Technical standards for the design, execution and testing of masonry buildings and for their consolidation).

In the case of non-load-bearing masonry, the requirements can be a useful reference, together with those of the UNI EN 771-1:2004.

The resistant elements of brick and concrete may contain punctures that meet the requirements of the Ministerial Decree 20-11-1987.

The mechanical strength of the elements must be demonstrated through certifications containing test results and conducted by official laboratories in the production plants, in the manner provided for in the ministerial decree above.

Director of Works should request an acceptance check, with the aim of ascertaining whether the elements to be implemented have the characteristics declared by the manufacturer.

4.1.2.3 GENERAL MATERIALS

The materials, products and components needed, made with traditional and / or artisanal materials and technologies, for the construction of the works, will come from those locations that the Contractor deems of its convenience, provided that, at the sole discretion of the management of the works, they respond to the characteristics / performances indicated below.

In the case of industrial products, compliance with these specifications may result from a certificate of conformity issued by the manufacturer and proven by appropriate documentation and / or certification.

All switches by 160 cm from the faucets or water point, must be covered by waterproof plate

IP55.

4.1.3 EXECUTION

4.1.3.1 DEMOLITIONS AND REMOVALS

The demolition of masonry, concrete, both partial and complete, must be carried out in order and with the necessary precautions, so as not to damage the residual walls, to prevent any injury to workers and to avoid inconvenience or disturbance.

It is therefore forbidden to throw away the materials in general, which instead must be transported or guided down, and to raise dust, so both the walls and the resulting materials must be properly wet. In demolitions and removals, the Contractor must also provide for any necessary shoring to support the parts that must remain and arrange so as not to deteriorate the resulting materials, which must still be able to be used within the limits agreed with the management of the works, under penalty of recourse for damage in favor of the contracting authority. Demolitions should be limited to the prescribed parts and dimensions. When, also due to lack of shoring or other precautions, other parts are demolished or the limits set are exceeded, the parts unduly demolished will also be rebuilt and restored at the expense of the

Contractor, without any compensation. All reusable materials, at the sole discretion of the management of the works, must be properly cleaned, guarded, transported and ordered in the places of storage that will be indicated by the management itself, using precautions not to damage them both in cleaning, both in transport, and in their settling and to avoid dispersion. These materials all remain the property of the contracting authority, which may order the Contractor to use them in whole or in part in the contracted works, pursuant to art.

Do not overload structural elements pavements to remain. Provide new supports and reinforcement for existing construction weakened by demolition, deconstruction, or removal work. Repairs, reinforcement, or structural replacement require approval by the Contracting Officer prior to performing such work.

4.1.3.2 FLOORING EXECUTION

Flooring means a building system whose purpose is to allow or improve transit and resistance to stress under certain conditions of use.

When it is not otherwise described in the other design documents (or when these are not sufficiently detailed) it is understood that each of the above categories will be composed of the following functional layers (Constructively a layer can perform one or more functions).

The flooring on a load-bearing layer will have as fundamental elements or layers:

1) the load-bearing layer, with the function of resistance to mechanical stress due to permanent or operating loads

2) the sliding layer, with the function of compensating and making compatible any differential slides between contiguous layers

3) the divider layer, with the function of transmitting to the load-bearing layer the mechanical stresses impressed by external loads if the layers constituting the flooring have significantly differentiated mechanical behaviors

4) the connecting layer, with the function of anchoring the coating to the divider (or carrier) layer

5) the coating layer with aesthetic tasks and resistance to mechanical, chemical stress, etc.

Depending on the conditions of use and the expected stresses, the following layers can

- 28 -become fundamental

6) layer of waterproofing with the function of giving the flooring a pre-established impermeability to liquids from vapors.

7) thermal insulation layer with the function of bringing the flooring to a predetermined thermal insulation.

8) sound insulation layer with the function of bringing the flooring to a predetermined sound insulation.

9) compensation layer with the function of compensating quotas, slopes, flatness errors and possibly incorporating systems (this layer frequently also has the function of a connecting layer).
