Multi-Purpose Field Technical Specifications and Construction Steps

Multi-Purpose Field Technical Specifications • Below you can find the technical specifications for the construction of multi-purpose sites, which are generally preferred for schools, public housing.

INFRASTRUCTURE WORKS

ENVIRONMENTAL GIRDER WORKS

  • After the application work is done in the area where the multi-purpose field will be built, the ground is levelled to zero code.
  • After the earthmoving work is done, the excavation is done at a depth of 25cm for the surrounding beams.
  • double surface wooden formwork with 25cm width and 50cm height is attached to the excavated area. Three lower and three upper reinforcing bars of Ø10mm diameter are placed inside the mould.
  • Ø8mm diameter stirrups are connected to the iron reinforcement with 25cm intervals.
  • After connecting stirrups, anchor pipes are fixed to the iron reinforcement in the mould with 3m spacing (Ø76x3mm) to the places where the surrounding poles will be placed
  • BS 20 (C 20) Ready-mix concrete is poured into the formwork.

SOIL FILLING TYPES

1- CONCRETE FLOOR (Applications: Tartan, Synthetic Turf)

  • Levelling is done by laying 5cm (16-22mm) crushed stone 2 in the field surrounded by concrete girders.
  • Levelling is done by pouring 0.5% (five per thousand) slope (12-15) cm mesh steel reinforced BS 20 (C-20) ready-mixed concrete onto the levelled crushed stone.

2- ASPHALT FLOOR (Applications: Acrylic, Synthetic Turf, Tartan)

  • The concrete is surrounded by a (10-15) cm stabilized material or plentmix filling and compacted with a vibratory roller.
  • 0.5% (five thousandth) slope (5-7) cm zero (0) surface asphalt is laid on the compacted ground and rolled.

3- ASPHALT FLOOR ON CONCRETE (Applications: Acrylic, Synthetic Turf, Tartan)

  • Levelling is done by laying 5cm (16-22mm) crushed stone 2 in the field surrounded by concrete girders.
  • Levelling is done by pouring 0.5% (five per thousand) slope (12-15) cm mesh steel reinforced BS 20 (C-20) ready-mixed concrete onto the levelled crushed stone.
  • On the concrete floor (5-7) cm zero (0) surface asphalt is laid and rolled.

IRON PIPE WORKS

  • After the infrastructure is completed, pipes of 4 m height (Ø60x2mm) are mounted vertically by welding to the pipes that are anchored to the concrete line (Ø76x3mm).
  • 3 rows (top, middle and bottom) Ø60x2mm pipes are welded horizontally.
  • Pipes are welded diagonally to corners, on short and long edges (Ø60x2mm).
  • For the lighting, 4 pieces of (Ø76x3mm) pipes with a 5m height are connected to the construction by welding.
  • One hinged door is made of pipe (Ø60x2mm) at the desired place.
  • The manufactured iron materials are painted with synthetic resin special metal anticorrosion paint (Dark Green), which combines the features of the anticorrosive protective topcoat glossy paint.• Multi-Purpose Field Technical Specification

WIRE MESH AND NETWORK WORKS

  • The area is coated spiral wire mesh around 4m high, 3.5mm wall thickness, having an interocular distance of 50x50mm, is coated with dipped galvanized PVC.
  • After the wire mesh is stretched and connected, 5 mm steel rope is stretched in 2 rows around the field, then the tensioned steel ropes are fixed with terminals.

LIGHTING AND ELECTRICAL WORKS

  • 4-8 pieces (varies according to field dimensions) Imported 400W Metal Halide bulb projectors are installed to the projector poles, which are manufactured with ladders.
  • Electrical connections are made with TSE certified rubber insulated 4 × 4 NYY Cable.
  • Electrical Installation up to the panel is installed and the projectors are delivered in working condition.

ASSEMBLY OF EQUIPMENT

Mounting of the equipment that is suitable for the project is done on the ground with eyebolts. (Basket Hoop, Tennis Poles, Volleyball Poles and other accessories)

FLOORING WORKS

 

TARTAN GROUND

  • Cured concrete or asphalt floor surface is cleaned and made free of dust and foreign matter.
  • Primer (undercoat) is applied on the surface to increase the retention of the material to be applied.
  • Following the primer layer, the SBR Granules with a diameter of (1-4) mm (specially selected) are mixed with 20% Polyurethane Binder and laid with a finisher having a  thickness of 8mm.
  • The laid material is expected to cure for approximately 24 hours.
  • At the end of the curing time (1-4) mm Diameter (High Strength and UV resistant) Colored TPV or EPDM Granules are mixed with 20% Polyurethane Binder and spread with finisher having a  7mm Thickness.
  • On the elastic floor, the game lines are drawn using acrylic paint and the field is made ready for use.

ACRYLIC FLOOR (Applied on asphalt)

  • Before the construction of the acrylic floor, the surface of the cured asphalt is cleaned and made free of dust and foreign matter.
  • Primer (undercoat) is applied on the surface to increase the retention of the material to be applied.
  • After the primer application, a Resurfecer layer is applied to cover the pores on the floor.
  • Three layers of Coushion (powder SBR mixture) are then applied to the substrate to form an elastic layer (upon request).
  • Two coats of Acrylic paint are applied on the created layer.
  • Game lines are drawn on acrylic paints according to the project and the field is made ready for use.

ARTIFICIAL TURF  

  • Geotextile Flecked Artificial turf felt is laid on concrete or asphalt ground prepared.
  • Sand and Granule Filled (5 Years Warranty, 20-26MM) Turf is laid on the felt. (Technical specifications vary according to turf types)
  • The junction points of the laid turf are bonded with the help of Helmetin cloth, 20 cm for the joints, 30 cm for the lines, using special two-component polyurethane adhesive
  • Field Game lines are cut and placed according to the project.
  • Special silicon sand, which is sieved, washed and kiln-dried sand is poured 22-30 Kg / m2 (varies according to the turf type used)
  • The laid sand material is brushed and the field is made ready to play.
