1.8 Floor Substructures Specifications and Survey Processes

It is the responsibility of the Architect, the Head Contractor or the Client to advise Starena in detail of the type and nature of the timber sports floor or synthetic/concrete surfaces to be utilised on the contract and to confirm to Starena what the OEM Sports Floor supplier’s dead load per wheel is able to be accommodated by the specified floor in a rating of kilogram per wheel.

It is the responsibility of the client to ensure that the floor is capable of withstanding the live and dead loads, as imposed by the retractable seating structure. All floors, irrespective of the type of floor, prior to commencement of installation must be verified by the client and a report supplied to Starena that shows they surveyed the floor level must be finished to a FFL of ±3mm over a 1m square.

The material weight and dead/live loads of the spectators on the telescopic stands should not exceed the point loads of the bearing capacity of the floor. It has to be considered that resilient sports floors have limited bearing capacities for static and dynamic loads. It is the responsibility of the client to ensure that the floor system, irrespective of its nature, can support the system. Clients are encouraged to engage independent engineering analysis – Starena will supply wheel of path dead/live loads for consideration. Starena will not inspect the floor for fit for purpose use – that is the responsibility of the Head Contractor or client.

In addition, detailed specifications on the selected floor are to be provided to Starena. Detailed component design will not commence until this information has been provided.

All floors must be finished to a FFL of ±3mm over a 1m square area.

On the basis that a very flat and level surface is required for the operation of the installation, the ±0.003 limit may be retained for the flatness assessment and be accompanied by a requirement that the finished surface be within ±0.003 of the specified level throughout the area for the installation.

The determination of compliance normally requires two processes: firstly, by measurement of a deviation below a straight edge (3m straight edge in any direction) of a nominated length, and secondly, by direct measurement of the level of the floor.

Alternate methods for assessing compliance have been developed in the USA, for application on assessing super-flat floors within the trafficable lanes in warehouses, between high-rise racking: these involve the use of specialised instrumentation with tilt sensors that are pulled across the floor.

In practical terms, the assessment generally involves direct levelling only, due to the difficulty of documenting results from measurements of deviations, especially over large areas.

The crucial parameters then become the specification of the spacing of the observations and the precision of the process.

In any method, the survey process may only take up a small part of the tolerance allowable on the surface being measured.

For determination of compliance, with a tight specification, the spacing of the observations will generally be 1.00m and for a specification of ±0.003, the survey process must be able to produce results to a tolerance of ±0.001 or better.

A survey tolerance of ±0.003 is appropriate for assessment of a surface that has a placement tolerance in the order of ±0.10.

For reliable data, with a survey tolerance of better than ±0.001, the observations may only be taken with a precise level and calibrated staff: this is a very expensive process: the observations are taken on a marked-out grid and the results are then transcribed into a cad package, for subsequent processing/review. The expense attaches to the time required for completion of the observations and the data entry process.

It is also not suitable for situations where limited head-room is available, e.g. observations under the tiered seating.

An alternative allows for the observations with a total station instrument, with modified observing routines. These instruments generally have an automatic target recognition facility, (ATR), and can track a prism as it is moved across the floor: this method allows for simultaneous determination of the position and level of the target. This data can be directly downloaded and processed within a cad/survey software package, removing the need for marking out a detailed grid and also the need for transcription of results.

The tolerance on the measurements however, is in the order of ±0.003.

A variation on this method is for the direct observation onto the floor, using the reflectorless capability of the total station instrument: a laser is used for the measurement. The advantage of this is that measurements may be taken to all areas where sight-line access to the subject surface is available, e.g. below the seating.

The tolerance on the measurements is also in the order of ±0.003.

The ATR procedure can be modified to improve the precision of the result, with manual sighting to the target: this involves a time impediment, but the precision may then be quoted to ±0.001.

A further alternative is available, which allows for very fast measurements throughout all areas, however, the reflectivity characteristics of the floor surface would need to be checked before this method could be relied upon to produce suitable results.

This method entails the use of a laser scanner for the data acquisition: a single scan would be required for the floor area with the seats in the closed position: two scans may be required for a survey of the floor, from beside the structure, with the seating open.

The scanner records up to 50,000 points per second and the floor area would be recorded with approx. 5,000,000 points. This data may then be converted into a surface model with a precision of around ±0.002, depending on the reflectivity of the surface.

The model can then be interrogated to produce level values on a 1.00m grid basis.

The scanning is the preferred method, however, as noted above, the performance of the instrument on the measurements to the floor surface would need to be reviewed before the process was applied/relied upon.

In the case of a timber floor, which incorporates a rubber blocking system (in their various formats), the floor must incorporate additional timber blocking , such that the rubber blocking does not depress any more than ± 3mm under load, from the retractable system when it is moving. If timber floors do not incorporate a rubber blocking system, the design of the floor must be such to accommodate the above.

Retractable Seating.

The supplier is to provide advice and drawings for the retractable wheel of path travel which the flooring supplier is to incorporate timber blocking, as noted above. The timber sports flooring supplier is to provide a drawing showing incorporation of the blocking. Refer seating package schedule for the typical load requirements for each seating structure and the blocking requirements.

1.9 Retractable Seating – Use of Carpet Under Retractable Seating


Although carpet applications are not recommended to be used in conjunction with Retractable Seating, it can be achieved using a specified tile system as per below.

Starena gives no guarantees, nor will Starena be liable, for any issues or damage as a result of the choice of carpet under Retractable Seating. Broadloom (or similar) will not work as the pile catches on the wheels.

Please see Starena recommendations below. These are products that have been proven to work in the past.


Starena collaborates with Feltex, who offer a range of carpet tiles in which Starena offers as a finish option for Retractable Seating platforms.

The carpet tiles are selected from two series types called Nocturnal II and Gem II.

Please review links below to the above carpet tile ranges. The recommended size of the carpet tile used should be 500mm x 500m.


After many years of experience, Starena recommends a specific glue to be used for the carpet tiles.

A Super Adhesive Glue that can be used: A commercial vinyl adhesive applied with a V notched trowel. The brand that works well is the Max Bond brand, the product needs to be applied to both the concrete surface and the underside of the carpet tile. A minimum of 48 hours curing period without trespass onto the tiles is advised.


Carpet Tiles must be installed by an experienced qualified carpet layer.

If during the assembly process or post commissioning of the system it is clear that the flooring level is not to specification, which impedes the efficient operation of the retractable seating system, Starena will accept no liability for these circumstances.

Installation Set Down Area - required

During installation, the retractable seating componentry is strategically placed on a footprint that is 2/3 that of the retractable seating plan, which enables the installation of the system to be well organised. This 2/3 footprint must be taken into consideration as to the total area required for installation of the system. No other contractor’s equipment is to be present.

Covering/Protection of floors during installation

If the installation set down area is a timber sports floor or synthetic floor, the floor will be covered with a layer of corrugated cardboard to protect the flooring. This area is then utilised to set out the retractable seating componentry for installation (refer above).

6. Use Of Telescopic Stands

Spectators should not be admitted to the telescopic stands for its first use until the client of the client’s agent, who should be a competent person, is satisfied that the structure has been properly installed and complies with the design criteria.

Spectators should not be admitted to the telescopic stands for subsequent events until the client is satisfied that the structure has been opened and set in accordance with the manufacturer’s installation instructions.

The numbers and distribution of spectators for which a grandstand has been designed should not be exceeded and consideration should be given to the access and egress arrangements.

During all events a sufficient number of stewards should be present in order to safeguard spectators.
