DESIGN AND SPECIFICATION

Consultation is the crucial first stage of the design and specification process. In a two way conversation we are able to develop a clear understanding of your needs and aspirations and at the same time it will allow us to propose potential design solutions and impart knowledge of the most suitable products. From preliminary budget estimates to the calculation of final itemised project costings, we are able to keep you informed of the total project cost.

Sports fields designed and specified by Turf One are designed literally from the ground up. Turf One team with geotechnical engineers and agronomists experienced in this specialised field. Design parameters including local climatic data; expected level of performance, i.e. elite competition or community use, match play or training; expected hours of usage and seasonal usage; resources available to maintain the facility and financial constraints will all be considered to ensure that your field is designed to provide the best outcome.

CONSTRUCTION

Turf One brings years of experience in sports field construction to each new project. Investment in a large fleet of laser (and GPS) controlled earthmoving equipment frees Turf One from reliance on sub-contractors and ensures that its fields can be built quickly, accurately and in the most cost efficient manner. All steps in the construction process are subject to inspection and testing to ensure adherence to a project specific quality assurance plan.

DRAINAGE

Local climatic and sub-soil conditions will determine whether it is necessary to construct a sub-surface drainage system for the sports field. Sub-surface drains can either be trenched into the sub-grade, or if an aggregate drainage layer is to be installed, laid flat on the profiled and compacted sub-grade as shown in the photograph. A drainage layer, typically 100mm depth of 7mm aggregate, may be specified for elite fields. GPS laser guided tractor-drawn scoops are used to spread the material to achieve accurate depth and surface profile.

IRRIGATION

Accurate setting of sprinkler heads prior to placement of the growing medium is an essential step. The design of the sprinkler system must take account of local climatic conditions. Sprinklers must be spaced to provide uniform and complete coverage even in windy conditions.

PREPARATION OF THE GROWING MEDIUM

The composition and depth of the growing medium will be specified by the consultant agronomist. Parameters such as infiltration rate and sieve grading which determine the depth of readily available water in the root zone will be specified. The sand must be spread and levelled with minimal compaction. GPS laser guided equipment is used to spread and level the growing medium to achieve accurate depth and surface profile.

TURF OPTIONS, SELECTION AND PLANTING

Turf options include planting sprigs, (line planting or incorporation of chopped material into the top layer of the growing medium), unwashed sod or washed sod. Plant species selection will depend on local climatic conditions, turf availability and budgetary constraints. Planting maxi-rolls saves time, results fewer joins between runs and less wastage.

TURF ESTABLISHMENT AND MAINTENANCE

Timing the planting to coincide with ideal growing conditions will result in fast establishment, strong root growth and minimal weed infestation. Root development of 100mm or more over a period of six or seven days is possible with the surface being ready for play within six to eight weeks.
