6. Shipment and transportation

During transportation of construction-purpose cargos, the Contractor shall meet the requirements of SNiP III-4-80, Part III "Rules of performance and acceptance of works", Chapter 4 "Safety precautions in construction", DBN A.3.1-5-96 "Organization of construction production". Transportation, storage and warehousing of materials, structures and equipment are organized as per DBN G.1-4-95 "Rules of transportation, storage and warehousing of materials, products, structures and equipment in construction".

Transportation of inflammable cargos shall be performed by the means of transportation equipped as per the rules and instructions for such cargo category.

Transportation and temporary storage of structures, products and equipment in the erection area shall be carried out according to the requirements of specifications for such structures (products), while for the non-standardized structures (products) it is necessary to meet the following requirements:

• Structures shall be placed in a position corresponding to their design, and if this condition cannot be met, structures shall be placed in the position convenient for transportation to erection site, taking into account that thei strength and durability shall be maintained;

• Outstanding pieces of reinforcement bars and outstanding parts shall be protected against damage;

• Small parts for installation joints shall be attached to the shipped elements or sent simultaneously with structures in the container with labels, identifying parts names and their quantity. These parts shall be stored under canopy ;

• Fastening parts shall be stored indoor , sorted by types and makes ; bolts and nuts shall be sorted by classes of durability and diameters.

The Contractor shall provide transportation, unloading and safe storage of all structures, equipment and materials necessary for construction of the substation. At the same time:

a) transportation of heavy, long and large-sized cargos shall be provided using specialized means of transportation. To avoid rolling or falling over during vehicle movement, the cargos shall be placed and fixed on vehicles according to specifications of loading and fastening of the given type of cargo;

b) insulators shall be transported packed in boxes or on grates. Transportation of insulators in bulk is for Tenderden;

в) in necessary cases, dump trucks shall be equipped with special stoppers in order to support the tipper body in the lifted position.

During storage, the structures shall be sorted by types, and stacked taking into account the sequence of installation.

Marking of cargo containers shall meet the requirements of GOST 14192-96.

Handling of dust-like materials (cement, lime, plaster) shall be carried out in a mechanized way. As an exception, cement unloading handworks are allowed at its own temperature not exceeding 40°С.

Before loading or unloading of precast reinforced-concrete structures, the installation ears shall be examined, cleared from grout solution or concrete and, if necessary, corrected without damage to the structure.

The Contractor shall independently perform inspection of road sections and bridges, along which the equipment and building structures will be transported.
