Delivery of concrete and laying of concrete on the maneuvering area CSLog in m. Grupa gm. Dragacz - case no. 104/2026

… min. W8. In total, 640,0 m3 of concrete should be delivered. 2) Laying on the finished ground a layer of concrete with a thickness of 23-24 cm by means of a concrete pump, with compaction by means of any equipment (vibrating patch, vibrating roller). Dehydration of the area will occur on the surface, on the adjacent green area. It is required to profile the square with a one-way drop of 1.5% over its entire length. 3) Laying of concrete should be carried out in rainless weather and ambient temperature above 5oC. If lower temperatures occur (4.9oC to -2oC), additives will be required to allow the laying of concrete under these conditions. In the event of local frosts (maximum -2oC), work should be stopped until the weather conditions improve, or the surface should be protected with mats. 4) Texturing of the surface by brushing to obtain a rough surface, allowing adhesion of the wheels in wet conditions. 5) Expansion fields by mechanical incision to a depth of 1/3 of the thickness of the concrete layer with a mesh of 6.0 x 6.0 m. the width of the gaps – 12 mm, the incisions should be made up to 24 hours after laying the concrete. 6) Filling expansion joints with bituminous flooding mass. Use a wide expansion cord to support the mass. 15 mm, which should be set at a distance of 3,0 cm from the bottom of the gap (dilatation void) 7) Care of concrete by protection in case of too low temperatures with protective mats and / or foil, depending on weather conditions 1) Due to the expected date of performance of the subject of the contract, the Contractor is obliged to take into account the possibility of low temperatures, frost, frost, rainfall and other weather conditions affecting the process of binding and maturing concrete. 2) The Contractor is responsible for the selection of concreting technology appropriate to the actual atmospheric conditions occurring during the implementation and expected during the maturing period of the concrete. 3) If the proper performance of the subject of the contract requires the use of technology of concreting at a reduced temperature, the Contractor is obliged to apply technological solutions ensuring the proper performance and maturation of concrete. 4) Technology, may include, in particular, the appropriate selection of components of the mixture, the appropriate temperature of the mixture at the time of laying, the use of appropriate admixtures / additives, appropriate surface protection and proper care. 5) The Ordering Party does not indicate a specific manufacturer or trade name of the admixture/additive. The choice of the admixture/additive, its type, dose and method of application is the responsibility of the Contractor, who is responsible for the correctness of the adopted technological solution. 6) The admixture/additive used must be intended for use in concrete mixtures in accordance with its properties, manufacturer's documentation and applicable regulations and standards. 7) The use of an admixture/additive does not release the Contractor from the obligation to perform other activities necessary for proper protection
