1.1 INTRODUCTION

Turner OCTO® Assembly Guide

SECTION 1.1 Introduction

This Assembly Guide contains the necessary information required to correctly assemble
Turner OCTO

®

System Scaffolds in accordance with appropriate methods of safe assembly.

The provision and utilisation of collective protection equipment and methodology is
recommended where practicable for installers of Turner OCTO® System Scaffolding.

Installers / Dismantlers of Turner OCTO® System Scaffolding must also be competent,
relative to the type of scaffold to be erected, dismantled or altered.

This Assembly Guide provides instruction for foot tied, non-foot tied, and pedestrian
categories (as listed within the Assembly Guide) built from the ground or other suitable
foundation.

Types of Turner OCTO® System standard conguration included within this Assembly Guide
are detailed on the Contents Page and limited to the maximum heights as indicated in
Section 1.7 Maximum Heights (page 57).

This Assembly Guide should be used in conjunction with a suitable Risk Assessment and
Method Statement (by user) relative to the project to be undertaken. It must be noted that
all employers have a responsibility to ensure that work methods (practices) and adequate
facilities / resources (including work equipment) are provided to eliminate or minimise risks,
in accordance with current legislation.

A complete separate safe system of work (Method Statement) is required for all other types
of scaffold.

Sufcient training, combined with necessary experience, must also be considered and be

appropriate to achieve competency to build or dismantle a particular scaffold type in question.

Please ensure you read and fully understand the manual, and follow the content during
scaffold erection and ensure that the scaffold is complete prior to use and / or handover.

This Manual must be made available to the user / installer of the Turner OCTO® Scaffold
System at all times.

Only competent and qualied personnel should undertake assembly, dismantling and

alteration (and organisation, planning and supervision) of basic Turner OCTO® standard

congurations, and consideration should be given to providing additional (minimum) training

beforehand, if required.

SECTION 1.2 Pre-use Inspection & Selection

1.2 PRE-USE INSPECTION & SELECTION

To ensure that a scaffold is assembled in a manner that prevents its component parts from
being accidentally displaced at any time, it is important that the following checks are carried
out:

• Ensure that all necessary components and safety equipment are available and
operational.

• Each component should be visually inspected prior to use and should be free from
defects.

• Steel components should be straight with no sign of corrosion, cracks or splits that
would impair strength or safety.

• Deck locks should be in good working order; hooks should be free of cracks and
corrosion, and bolts should be tight and locking nuts tted.

• Stiles or Ply inserts should not be punctured or worn to a degree that would impair

strength or safety.

Damaged or incorrect components must not be used.

Pre-use inspection should ONLY be carried out by a competent person.

standard congurations,

and consideration should be given to providing additional (minimum) training beforehand, if
required.

Ensure that all necessary components and safety equipment are available and operational.

Inspect components for signs of damage or incorrect functioning prior to use. Damaged or
incorrect components should not be used.

Erect Exclusion Zone and t Warning Signs to comply with current legislation.

Before assembling the scaffold structure, check that the location for the structure does not
present any hazards during assembly, dismantling, moving and safe working with respect to
ground conditions, level and slope and obstructions.

Ensure the scaffolding is to be assembled on suitable foundations capable of withstanding
the loads imposed by the scaffolding and, where appropriate, adequate base boards to be
provided.

Fit toeboards on all working platforms.

DO NOT afx sheeting of any type to the scaffold structure without a proper Design.

Turner OCTO® System Scaffolding is compatible and can be used with another similar type
of system scaffold; however, both types have different load bearing capacities. When the
components of both types are mixed, then the load bearing capacities of the compatible product
should be used instead of the data for Turner OCTO® System.

SECTION 1.4 Safety Information

1.4.2 GuardAid

®

(i) User Instructions

The GuardAid® Positional Tool (Figure 1) provides the scaffolder with integrated safety and
safe systems of work throughout scaffold assembly, dismantle and alteration; therefore,
eliminating the risk of fall from height and enabling compliance with current legislation.

GuardAid® is a scaffold tool used to position, while holding secure, a scaffolding guardrail,

before it is xed and locked into place.

GuardAid® enables existing components to be utilised as integral advance guardrails. This
is achieved by combining a sequence of steps; holding, securing, guiding and then enabling

automatic positioning, xing and locking the existing scaffold component.

To use the GuardAid® Positional Tool safely, each guardrail
component can be lifted into position by two operatives (one
at each end of the guardrail - as illustrated opposite).

The GuardAid

®

Positional Tool consists of various component
parts within the Tool Head (Detail ‘A’) that have different
functions for the scaffolder using the tool.

The operatives should then simultaneously raise the guardrail

and t the guardrail into the cups of the standard.

Standard Cup Hook

Should the scaffold standards be slightly off the plumb then one
operative should locate one end of the guardrail into position
and locate in cups allowing wedge to drop and become loosely
engaged. This operative can then assist in locating the opposite
end of guardrail by using the Standard cup hook (of the GuardAid®
Tool) pulling the standard to the vertical (Figure 3); therefore,

allowing the guardrail to be tted correctly.

(ii) Wall Scaffold Assembly Procedure using GuardAid

®

This section shows the assembly procedure for a fully boarded tied wall scaffold using
the GuardAid® Positioning Tool; Turner’s recommended system of work for safe scaffold
assembly, dismantle and alteration.

Prior to the commencement of any scaffolding operations appropriate training is recommended.
Forward planning and organisation to ensure the amount and best utilisation of the correct
materials, before assembly procedures commence, will be rewarded throughout assembly
and in the nal scaffold constructed. Please refer to Section 1.5 Assembly Procedures for
further details.

1. Position two Jacks to approximate starting position

of rst bay (on base boards if required) and place
rst pair of appropriate Standards on Jacks then

connect transom (Horizontal) in lowest cups.

2. On outer Standard x Bracing Guardrail (to suit
required bay length) in direction of the length of the
scaffold.

3. Position next pair of Jacks and place Standard

on outer Jack. Connect Bracing Guardrail and x

transom to bottom cup.

4. Place appropriate inner Standard and connect
transom between Standards.

5. Fit Horizontal (ledger) between the inner
Standards (along length of bay) in bottom cups.

6. Check levels along 1st transom, ledger and nally
2nd transom and check that bay is square.

Note It may be advantageous to place a Deck in the bay to assist in “squaring” the bay. Place
an appropriate-sized Deck in the bay against the inside Horizontal (it should be parallel).

If required, make any adjustments and repeat as necessary.

7. Fix required Bracing Guardrail to outer Standard
and leave to “hang” in direction of length of
scaffold.

8. Place next Standard on Jack (set to minimum
height), lift into position and connect Guardrail.
Adjust Jack to sit under Standard.

Note On sloping ground, steps should

be cut to ensure the base boards lie at

and level.
