  6. LED lighting system of an indoor field at night

    6Lighting, Equipment & Delivery

    LED floodlights, goals and nets are installed; the field is measured against a checklist and handed over.

Technical Specification

Turf Field Specification: Proper vs. Substandard Practice

The price difference between turf fields usually hides in the items you cannot see. In the table below, we openly share the questions we recommend asking when comparing quotations.

Technical specification comparison
Construction ItemOur Recommended StandardLow-Budget PracticeLong-Term Consequence
DrainageLateral + main lines, graded levellingSurface slope onlyPooling in rain, shortened turf life
Concrete beamsC-25C-16 / no beamsLoosening posts, fence deformation
Turf system45–55 mm monofilament, UV-stabilisedFibrillated, low weightShine and flattening within 2–3 years
InfillWashed silica + SBR granulesUnsieved sandHard surface, injury risk
LightingLED, ~200 lux averageMetal halide / too few mastsHigh energy cost, dim zones
PerimeterGalvanised + PVC-coated meshPainted pipeCorrosion within 3–5 years

Your field's lifespan depends less on the turf than on the accuracy of the foundations. That is why every item in our quotations lists its brand, weight and standard in writing.

Outdoor Turf Field Construction in Ankara

Ground conditions are the decisive item in outdoor turf field construction in Ankara: the city's clay soil makes correct drainage sizing essential. During the survey we measure the gradient and water discharge direction, and design the beam and drainage details accordingly. City-centre sites incur neither crew travel nor lodging costs, so quotations come out lower than for out-of-town projects of the same size.

Indoor Turf Field Construction in Ankara

For indoor turf field construction in Ankara, the steel structure is dimensioned against Central Anatolian snow load and prevailing wind figures — an item that should not be compromised in this climate. Investors increasingly favour indoor fields because the facility stays in operation through Ankara's extended winter months.

School, Residential and Institutional Projects

We carry out turf field construction and multi-purpose court works for school grounds, residential complexes, public institutions and sports clubs in Ankara. Work schedules are planned around school holidays or residents' usage hours as appropriate. For institutional procurement we prepare the technical specifications and drawings required for tender files.

Construction Guide

Key Points in Turf Field Construction

Below we have collected the technical topics raised most frequently during our site visits, together with the decisions that determine how long a field lasts.

Why Is the Ground Survey the First Step in Pitch Construction?

A field's decade-plus lifespan is decided by the foundations laid on day one. The ground survey measures bearing capacity, water retention and gradient; the drainage section and sub-base thickness are designed from this data. Fields built without a survey may show no problems for two years, but settlement, standing water and surface undulation appear from the third winter. What is saved at this stage is far less than the cost of later repairs.

Detailed cost breakdown →

Concrete Beams and Sub-Base: The Field's Structural Skeleton

The most critical item in pitch construction is the one you cannot see. A C-25 standard perimeter beam is cast over a compacted aggregate base; the beam provides a fixed support for the perimeter system and preserves the field geometry for years. Ground level is verified by laser measurement. On a field that is out of level, ball roll is compromised — and replacing the turf will not fix it.

Detailed cost breakdown →

Choosing Artificial Turf: Which Weight, Which Pile Height?

For fields in commercial use we recommend UV-stabilised monofilament yarn at a 45–55 mm pile height. Yarn weight per square metre determines the turf's load-bearing and recovery capacity; turf of lower weight appears no different during the first year and shows the gap from the third year onwards, as fibres lie flat. Washed silica sand and SBR granule infill are spread uniformly by machine. Brand, weight and warranty details of all materials are documented in the contract annex.

Selecting the Steel Structure for Indoor Pitches

In indoor fields the steel frame is dimensioned by structural calculation against the snow load and wind pressure of the locality. Arched truss systems span wide openings without columns, leaving the playing area unobstructed. Corrosion resistance on load-bearing profiles is achieved with galvanised coating or epoxy stove enamel; light transmission through the cover lowers daytime energy use, while condensation control governs winter comfort. The structural design and calculation report are included in the handover file.

What Is the Right Lux Level for Pitch Lighting?

Lighting is the largest operating cost item, so it should be planned correctly from the outset. An average of 200 lux is sufficient for recreational play, while competition standard requires a higher level and more uniform distribution. Fixture count and angles are set by photometric calculation; preventing glare and avoiding disturbance to neighbouring plots are part of the design. LED fixtures consume markedly less than conventional floodlights.

When Should Construction Start? The Effect of Season

In outdoor pitch construction, the concrete and turf installation stages are weather-sensitive: concrete is not poured in frost, and turf is not laid on wet ground. Spring and autumn are the most productive periods. For indoor fields, steel fabrication continues in the workshop, so seasonal impact is markedly lower. For projects that must be ready for a season, we build the schedule backwards and plan the critical stages around the weather window.

Good to Know

Frequently Asked Questions About Turf Field Construction

How long does turf field construction take?

Outdoor turf fields take 30–45 days on average; indoor fields, including steel structure fabrication, take 60–75 days. The schedule depends on size, ground conditions and weather. The exact timeline is committed in writing in your contract.

How much does turf field construction cost in 2026?

Costs vary by size and system; as of 2026, turnkey projects range between TRY 1,900–2,500 per m² for outdoor fields and TRY 3,500–4,500 per m² for indoor fields. The exact figure is presented item by item after a free site survey.

What are the standard turf field dimensions?

The most common commercial sizes are 20×40, 25×45 and 30×50 metres. 20×40 fields suit 5-a-side and 6-a-side play; 30×50 fields suit 7-a-side and 8-a-side. The best size for your land is determined together during the survey.

How quickly does a turf field investment pay for itself?

Depending on the business model and location, turf field investments typically pay for themselves within 18–36 months. In high-demand areas and with indoor fields this period can be shorter. We share a location-specific feasibility summary at the survey meeting.

Which permits are required to open a turf field?

A building permit consistent with the zoning status is required from the municipality, and a business licence at the operation stage. For indoor fields, the building inspection process also applies. We support your permit file with project drawings.

Should I choose an outdoor or an indoor field?

Outdoor fields require a lower investment; indoor fields generate revenue through winter and raise annual occupancy. The decision should reflect your land, budget and local competition. We present a comparison of both scenarios at the survey.

Which turf system do you use?

For commercial fields we recommend UV-stabilised monofilament turf with a 45–55 mm pile height, infilled with washed silica sand and SBR granules. Brand, weight and warranty details of all materials are documented in the contract annex.

Can an old field be renovated?

Yes. If the existing sub-base is sound, the field can return to service quickly with turf and infill replacement alone. Any sub-base issues are identified at the survey and reported as separate items. Renovation projects are typically completed within 7–14 days.

Do you serve every city in Türkiye?

Yes. Our base is Ankara, yet we survey and build in all 81 provinces. On projects beyond the city, crew accommodation and logistics are arranged by us and itemised openly in your quotation.

How does the quotation process work?

After you submit the form or call us, your survey appointment is scheduled within 24 hours. Following the survey, a written quotation prepared for your size, ground and system preference is delivered with every construction item listed individually.

Which districts of Ankara do you serve for turf field construction?

We provide turf field construction across all 25 districts of Ankara: Çankaya, Keçiören, Yenimahalle, Mamak, Etimesgut, Sincan, Altındağ, Pursaklar, Gölbaşı, Polatlı, Kahramankazan, Akyurt, Elmadağ, Çubuk, Beypazarı, Ayaş, Bala, Haymana, Kalecik, Kızılcahamam, Nallıhan, Güdül, Çamlıdere, Şereflikoçhisar and Evren. As our office is at Next Level in Çankaya, city-centre surveys are usually completed within the same week.

What does turnkey turf field construction include?

Turnkey turf field construction covers survey and design, excavation and levelling, the drainage run, the concrete beam and the field base, perimeter fencing and cage system, monofilament turf installation with silica sand and SBR granule infill, line marking and LED lighting. Player shelters, scoreboards and stands are optional; each appears as its own line in the quotation. On delivery day the field is left ready for play.

How much land is needed for a 30x50 turf field?

For a field with a 30 × 50 m playing area, 1,500 m² alone is not sufficient; margins must be left on every side for the perimeter safety system, player shelters and service access. In practice, an area of roughly 35 × 55 m — about 1,900 m² — should be planned. We assess whether your land suits this footprint during the site survey.

Why is drainage so important in turf field construction?

Water management is the first factor determining a field's service life. Where drainage is inadequate, water pools after rain, infill material washes out and shifts, the surface hardens and the turf backing degrades over time. We therefore measure the site gradient and discharge direction during the survey, and design the drainage line together with the field base and beam details. Rapid surface discharge is decisive for a service life beyond ten years.

Detailed cost breakdown →

Which structural system do you use for indoor turf fields?

For indoor turf field construction, the steel load-bearing system is sized by structural calculation against the snow load and wind pressure expected at the project location. Arched truss systems span wide openings without columns, so the playing area is not obstructed. Corrosion resistance on load-bearing profiles is achieved with galvanised coating or epoxy stove enamel; light transmission and condensation control govern the cover. The structural design and calculation report are provided in the contract annex.

Which criteria matter when appointing a turf field contractor?

The main criteria are an itemised written quotation, turf documented with brand, weight and warranty details, a structural design for indoor fields, drainage details shown on the drawings, and a delivery schedule committed in the contract. A lump sum whose scope is left undefined brings the risk of extra items surfacing appearing later. Visiting completed reference fields in person also supports a sound decision.

Do you build turf fields for schools and residential complexes?

Yes. We carry out turf field construction and multi-purpose court works for school grounds, residential complexes, public institutions and sports clubs. Work schedules are planned around school holidays or residents' usage hours as appropriate. We prepare the technical specifications and drawings required for institutional procurement and tender processes.

Do you provide maintenance support after construction?

Yes. At handover we leave you a written maintenance programme drawn up for your own field, covering brushing frequency, infill top-up intervals, line and seam inspections, and lighting maintenance. Brushing and topping up the infill on schedule keep the fibres standing and add appreciably to the service life of the field. When turf renewal is eventually needed, you can continue working with the same team.
