Steel stands are typically designed as temporary structures built using a scaffold system. Steel stands are usually reinforced with additional elements that form the support system selected depending on the structure’s size, type of event, movement load, etc. Such elements are mostly bracing structural elements and are important in the design process of stands. Not only the use but also the arrangement of such structural elements is essential for dynamic structural resistance. MARMA STEEL AND SPORTS STRUCTURES stands are specially produced and assembled according to your requirements and relevant considerations. Therefore, depending on some criteria and requests, steel stands can have different styles and structures. Determining factors include: - Seating capacity - Spectator flow - Area usability - Requirements of the geographical structure - Applicable Building Codes - Revenue Generation MARMA STEEL AND SPORTS STRUCTURES representatives will work directly with you to guide your project from start to finish. Site measurement, product planning, design consultation, and installation are all parts of the special stand services we offer. STEEL STAND SPECIFICATION: T.C MINISTRY OF YOUTH AND SPORTS GENERAL DIRECTORATE OF SPORTS FACILITIES DEPARTMENT PORTABLE STEEL STAND TECHNICAL SPECIFICATION 1.0 DOCUMENTS TO BE SUBMITTED TO THE ADMINISTRATION AFTER THE CONTRACT Within 30 days from the date of delivery, the contractor will submit to the administration: - The "FACTORY PRODUCTION CONTROL CERTIFICATE" issued under the 305/2011/EU Construction Products Regulation and accredited by an organization accredited by TÜRKAK according to the EN ISO/IEC 17065 standard, within the EN 1090 EXC 3 implementation class by the company manufacturing the steel stand. - The TS EN ISO 3834-2 "QUALITY REQUIREMENTS FOR FUSION WELDING OF METALLIC MATERIALS" certificate, showing the manufacturing company fulfills the quality requirements for fusion welding of metallic materials accredited by an organization accredited by TÜRKAK. - A contract made between the contractor and the stand manufacturer who has "EN 1090 EXC-3 and TS EN ISO 3834-2" certifications. After the administration notifies the contractor in writing about the compliance of the aforementioned document and the contract made with the manufacturer, stand production will commence. Documents submitted to the administration will be deemed accepted if not rejected within 20 days. During the continuation of the work, if it is determined that the approved manufacturer by the administration is not carrying out the work, or that the manufacturing is being carried out by another manufacturer, the administration will immediately stop the work and remove the unacceptable materials from the construction site at the contractor's expense (even if they were installed). After the completion of stand manufacturing, an inspection report indicating that it was carried out in accordance with the project's specifications and technical specification, will be prepared by an organization accredited by TÜRKAK and submitted to the administration before provisional acceptance. Up to 50% of the project value for stand manufacturing can be paid. The remaining 50% will be included in the payment after the inspection report is delivered to the administration. The work will not be considered finished unless the compliance report is submitted to the administration. 2.0 STATIC The static calculations of steel spectator stands are made according to the load of 150.00 kg/m2 snow in the first-degree seismic zone. A dynamic load of 500.00 kg/m2 is assumed as the floor load. 3.0 ALL MANUFACTURING OF STEEL SPECTATOR STANDS IS GALVANIZED 4.0 FACE BEAMS AND STEP SHEETS Face beams and step sheets are manufactured by bending galvanized sheets. Detailed manufacturing drawings are available in the manufacturing sheets, and they must be manufactured meticulously adhering exactly to the manufacturing sheets. Otherwise, the anticipated load capacity may not be carried. Step sheets are made of t=1.50 mm galvanized sheets, reinforced with bent galvanized sheets (ribs). Its total length is L=3000 mm. The spines are attached to the step sheets using the toxe method, which avoids damaging the galvanized sheets. The toxe system creates connections by compressing the galvanized sheets together without perforation. They will not be fastened using smart screws, welding, etc. Face beams are made of t=2.00 mm galvanized sheets, with a total length of L=3000 mm. 5.0 MANUFACTURING All manufacturing will take place in the factory adhering exactly to the manufacturing sheets, and only assembly will occur on-site. The entire structure can be disassembled and reassembled. Welding joints on-site are strictly forbidden and will not be tolerated. The stands consist of units, with each unit having a length of 6.00 meters. Its width changes according to the number of selected rows and the project. Additional units can be added to the stands later. Connection bolts are electro-galvanized. 5.6 Roof trusses and columns are constructed as fabricated beams; the parts bonded together will be welded according to the welding thicknesses specified in the manufacturing sheets. 5.7 Roof purlins, step sheets (P1-P2), face beams (K1), and roof trapezoid will be manufactured from galvanized sheet metal, while the other parts will be galvanized using the hot-dip method. 6.0 FOUNDATION Based on the application project, the foundation of the stand will be manufactured. It will include two layers of Q188 / Q188 (Ø6) reinforcement steel, using C 25/30 (Poz 15.150.1005) grade concrete. Spacers will be placed at one per square meter between the reinforcement layers. 7.0 ARCHITECTURE The riser height of the steps is 31.50 cm, with a width of 80.00 cm. Seating chairs will be placed at 45.00 cm intervals. In each unit, a 0.60 cm wide exit corridor will be left. BACKREST PORTABLE STAND SEAT Stadium seats should be produced from “Original raw material” (100% Polypropylene Material). No non-standard (scrap) material should be mixed within the original raw material. Stadium seats should be of bright and vibrant colors, with a homogeneous color distribution. The seats should contain an Ultraviolet Stabilizer to ensure resistance to UV and exterior factors. Whether the UV additive is present should be documented. High resistance to impacts is essential. Compliance with TSE 12727 standards is necessary. Seats should have flame retardant additives (Fr- Flame Retardant Additives), with fire resistance classified as 11925-2 standard 13501-E. The dimensions of the seating area should be approximately 42-45 cm in depth outside-to-outside, 42-45 cm wide, and 30-33 cm high for the backrest. The backrest should be rib-reinforced internally to resist breakage under load, with a double-walled backrest. Seats should possess an orthopedic seating feature, ensuring comfort for the back and legs. The front of the portable stand seat should be designed to prevent the hand from entering between seats, making their removal difficult. No water should accumulate on the portable stand seat. Water should be designed to drain not through holes, but via a water drainage channel present in the product, to prevent rusting of the mounting equipment, draining to the step below the seat in preference. The portable stand seat should have a TSE Quality Certificate. The product should meet FIFA standards in terms of durability, with a four-point connection based on the model used. The supplier should have ISO 9001: 2015, ISO 14001:2015, and OHSAS 18001-2007 Quality System Certifications. It should be certified whether the seats conform to the 11925-2, 13501-1E class. After seat installation, an accredited laboratory company by FIFA will take 2 samples from the mounted seats on the stand and submit them to a university with a "Department of Polymer Science and Technology": - Whether the seat production material is 100% polypropylene - Whether the seats have flame retardant additives (Fr- Flame Retardant Additives), complying with the non-flammability feature 11925-2 standard 13501-E class - Whether the UV additive is present in the product will be documented by the university.
