Method of Statement for Raised Access Floor.


The purpose of this method statement is to outline the materials and labor required to  undertake the Raised Floor works in a safe and controlled manner, compiling with relevant  legislation, standards, and Codes of practice. 

The method statement shall be briefed to all appropriate operatives to ensure that they  are aware of the work sequence and of any project specific requirements. 

General.

Prior to works commencing, the Site Engineer shall ensure that the following activities have been  completed and signed-off by the Consultant.

Drawing must be approved for construction by the Consultant.  

The Site Engineer shall ensure that the necessary Statutory Authorities approvals have been received.  

Material 

  • Raised Floor Calcium Sulphate Panel   Round Head Pedestal FFH-500mm. 
  •  Stringer 
  •  GI Through Bolt Anchor 
  •  GI L-Angle 

Setting Out and Installation Procedure.

The installation may only be started if the admissible climate for the installation is reached, and the façade is closed. 

The subfloor must be dry, even, solid as well as free of cracks, craters, and chemical substances (Grease, oil). The overall drying must be insofar as that no considerable shrinking must be expected anymore. 

We generally recommend providing the subfloor with a dust Proof-binding paint to guarantee a proper gluing of the pedestals. The subfloor must be broom-cleaned or otherwise vacuumed. 



The subfloor must be sufficiently resistant to abrasion. Any floated-up layers of fine mortar or loosely adherent parts must be removed before installation. 

The subfloors must be sufficiently load-bearing and to be able to take up all occurring loads. The subfloor must be within the levelness tolerances accordingly. 

The room must be checked on rectangularity to avoid small cut panels. 

The floor areas must be sectioned respectively arranged sensibly before the start of the installation and make sure pedestal should not collide with cable tray or other existing service. 

Co-Ordination with MEP team to avoid bridges and pedestal marking reference line to be given before proceeding the installation.  

Cut resp. cut-out panels are generally to be supported sufficiently with pedestals and/or profiles. 

A sealing tape (wall connection tape) must be provided at all rising building elements wherever it is required to be used. 

Turn around the pedestal and place it at reference point. Level pedestal to the required height with a levelling instrument (hose levelling instrument, levelling device, laser or similar). 

Attention: Consider the thickness of the panel! 

Let pedestal dry acc. to the information of the manufacturer of the pedestal glue.     

Compensate large unevenness by means of wedges. 

Adjustment of the raised floor pedestals for the first raised floor panel. 



Install the further two raised floor pedestals with the required grid dimension and level the pedestals to height by turning the adjustment nut. 

Unroll wall connection tape wherever required and glue it with the adhesive side flush to the upper edge of the raised floor panel (on two sides with corner panels). 

Cut the wall connection tape acc. to the edge length of the panel. 

Place reference raised floor panel on the installed raised floor pedestals. 

Install pedestal at the yet unsupported corner. 

Adjust pedestal on height with adjustment nut. 



Check and eventually adjust reference panel in both directions with the raised floor water level.  

Check again the levelling on height to the reference point and readjust at the pedestal if necessary. 

Setting up a line for the installation of the first row of panels parallel to the wall resp. to the first panel. 

Checking of the alignment of the line. 

Install further raised floor pedestals and panels of the first row. 

Check and eventually adjust the installed panel with a raised floor water level in both directions.  

Compensate possible panel tolerances with aluminum pads. 

Measure the size of the cut panels to determine the required panel format respectively.  



Mark the required dimension of the cut panel on the raised floor panel and the required cutting line. 

Putting in the cut panel carefully and with slight pressure into the raised floor grid. 

Check panel on proper seating, shifts in height, height tolerances and eventually adjust. 

Secure pedestals against height displacement. 

Insert stringer at pedestal head.
