SICURO Parapet

INSTALLER MANUAL

VERSION 2 March 2018

Product introduction

Sicuro parapets are made from galvanised steel posts, rails & rail joints. These are bolted together with galvanised & stainless steel fasteners onto anchors to create a permanent vehicle restraint system.

The Sicuro parapet has post centres @ 2000mm Maximum post centres at the end of Sicuro parapets are 2000mm Maximum rail overhangs at the end of Sicuro parapets are 450mm

There is no statutory requirement to install safety fences or barriers but if they are provided risk assessments must show that they create no additional hazard.

The system has been tested in accordance with parts 1 & 2 of BS EN 1317.

When used on motorways and trunk roads it must also conform to the current requirements of Highways England.

Locations and usage will be determined by an appropriately qualified designer.

This manual does not include design criteria, and is therefore to be used only to demonstrate competence in handling and installation.

However a basic understanding of the performance value of the system is included to assist in prevention of misuse. Vehicle restraint system is categorized according to containment value (N1, N2, H1, H2 etc) and working width (W1, W2, W3, etc).

These values are obtained as a result of dynamic (actual impact) tests using a variety of different vehicles to produce the containment and working width values.

Typical values in relation to SICURO Parapets are shown below.

Requirements to install, inspect & repair Sicuro Parapets

In essence any company wishing to install Parapets on motorways and trunk roads must work to the specifications laid out in the sector scheme document. This will ensure compliance with Highways England requirement that all companies must have third party certification for a Quality Management Scheme that is administered in accordance with a National Highways Sector Scheme as mentioned earlier.

To ensure that the installation, inspection & repair is both appropriate and adequate all installers must also be qualified to the standards laid out in sector scheme document 5b.

This course has been registered with Lantra Awards and is recognised as being compliant with Sector Scheme 5b. Those who successfully complete the course will be issued with a Lantra Awards registration card. This will be in addition to any registration card that has already issued in respect any other type of fencing.

All sector scheme documents are published by UKAS (United Kingdom Accreditation Service) and can be viewed on their web site in full.

Safety zones during installation reminder

During installation Highways Agency Chapter 8 safety zones must be established and maintained.

It is not possible to install the parapet unless such a safety zone is provided. It is suggested that a work area of not less than 1.5 metre will be required between the parapet and the safety zone.

On motorways the safety zone must be 1.2m regardless of any temporary speed limit

On other roads if there is a limit of 40mph or less then this may be reduced to 0.5m

Only leave the work area when it is absolutely essential.

Installers must not store materials in the Safety Zone.

Safety Zones for Offloading and Loading

As previously stated the swinging load must be controlled with correctly fixed rope tethers. The load must not be allowed to swing over or into live traffic lanes.

Suitable safety zones will need to be considered as part of the planning process taking into account the lengths of the units being delivered.

Strong winds which will affect the controllability of the suspended load must be risk assessed

The load should be lowered so that it is immediately above the ground as soon as it is clear of the lorry and then jibbed out to the final position.

March 2018

LIFTING EQUIPMENT

Required basic checks by the operator before using the lifting equipment

• Current Lift Plan and associated RAMS available • What is the safe working load of the equipment? • Are there are any defects with the equipment? • There are no overhead cables • The vehicle is stabilised • The vehicle is on reasonably level ground.

Pre-lifting checks by the operator

• Competent and experienced • Check the safe working load of any slings or chains • Establish the weight of the load and accessories • Check that the area to receive the load is clear • Ensure that the load will not swing out of control, use tag lines • Provide protection between sharp edges of the load and slings • Ensure that the load is balanced.

Lifting restrictions

The operator must not allow

• The load to swing the load over any other workers, exclusion zones • Others to walk under a suspended load • The load to swing out of control • The jib or load to swing into a live traffic lane • Not exceed the safe working load

Operators post lifting procedure

• The operator must check to ensure no damage has been caused to the slings • Slings have in date certification and SWL identified • Secure the crane in such a way that it cannot move during the transit • Length of Slings • Slings should not be longer than the minimum required to give the correct angle

between the legs. If an excessive length of chain or sling is used, crane movements will take longer for the hook to be in a position where it can be reached.

WORKING AT HEIGHT Definition of Height The HSE do not recommend a minimum height where edge protection should be provided. The risk assessment should identify the risk of a fall & advise measures to prevent a fall happening. A fall from a height of 150mm could cause a twisted ankle & therefore action must be taken to prevent a fall.

The type & duration of the works will determine the measures used to prevent falls.

Working at height on parapets Most parapet works take place at locations where the parapet will provide a permanent edge protection that prevents vehicles & pedestrians falling from height. The location is almost certain to have falls from height as a risk to the parapet installers therefore the risk assessment must address the risk of operatives & materials falling.

The most effective method of edge protection is a scaffold on the outside of the parapet that allows free access to the parapet anchors.

Parapet installers must not adjust or tamper with any scaffold or edge protection provided.

If installers become aware of defects in the edge protection, works must stop & the client informed.

Works must only proceed with a safe edge protection in place.

The main contractor will sometimes use the cradle anchors provided for the parapet as anchors for an edge protection scaffold. It will be necessary to remove the edge protection to install the parapet.

Parapet installers must not remove the edge protection to gain access to the parapet.

Once the edge protection is removed, alternative methods need to be found to prevent men & materials falling from the parapet

Where no edge protection is available or it has been removed prior to parapet installation, it may be possible for the parapet installers to install the parapet wearing a safety harness secured to a suitable anchorage point.

The safety harness must be free from defects & adjusted to fit the wearer.

The lanyard must be free from defects & the spring loaded clips must have a screw lock.

The anchorage for the lanyard must be capable of holding the load of operatives if they fall.

The lanyard should not be secured to a vehicle; there is a risk that the vehicle may move whilst installers are tethered.

There must be a method of preventing materials & tools from falling.

Hand tools can be tied to installer’s wrist or harness.

Materials cannot be tethered to the installer.

Access for pedestrians, vehicles & other trades under the area of works must be prohibited

A method of recovery for a fallen installer must be advised & recorded prior to works starting.

March 2018

Mobile Elevated Work Platform (MEWP)

Two types of MEWP are available for parapet works A Cherry Picker can be used to access the works from under the parapet A specialist inspection platform that goes over & returns back to the parapet.

The MWEP is delivered to site by the hire company

Operatives must be trained to operate the MEWP

A harness must be worn & tethered whilst working in a MEWP

March 2018

Prior to erection of the parapet the anchors will be tested & results recorded on Site test report sheet GQF-54 Iss 2 June 09

The ratio of anchors to be tested at site is determined as below

1 No anchor test on each length parapet where the number of cradle anchors is 30 or less 2 No anchor test on each length parapet where the number of cradle anchors is greater than 30 & less than 60 3 No anchor test on each length parapet where the number of cradle anchors is greater than 60 & less than 90

An additional test will be undertaken for additional anchors in the ratio of 1:30

If an anchor fails the test then the parapet must not be installed, the parapet proprietor is to be Informed

Test anchors

1. Confirm with client, which anchor location will be tested.

2. Set up rig above anchor, level rig with adjustable screwed legs.

3. Place testing adaptor over anchor and connect with M20X90 stainless steel bolt.

4. Pump jack to take up slack in rig.

5. Place DTI gauge plunger onto head of bolt, set gauge to zero.

6. Load anchor @ 10kn for 30 seconds and record reading on DTI.

7. Repeat this procedure @ 20kn and in 10kn increments up to 70kn, record readings.

8. At 80kn lock off the hydraulic jack and hold the pressure for 5 minutes, record the reading.

9. During this last test monitor the reading on the force gauge, should it drop below 80kn, pump up as required.

10. If the anchor moves more than 1mm it has failed.

11. Slowly release pump pressure and record the return pressure on the DTI.

12. Remove test rig.

13. Ensure a test record sheet is completed for each anchor and a copy is returned with site

records to the contracts manager.

Conformity, Maintenance and Repair

Page21- March 2018

General Information Where maintenance or repairs are required to be carried out, the installation procedure for installation in the forgoing paragraphs shall be followed unless otherwise stated.

If not subjected to impact damage, special corrosion conditions such as a chemical spillage, vandalism or theft of components, relatively little maintenance will be required. It is encouraged that the following is regarded as the minimum level of attention that will be afforded the system.

Conformity New works will be initially inspected to ensure the system has been installed to the correct specification and ‘signed off’ by the installer in accordance with Sector Scheme Document 5B. All fasteners are tightened to the specified torque and that random checks of torques have been made with a calibrated torque wrench. System heights, with an accepted tolerance of ± 30mm (+30 -0 for railways) are to be confirmed with relevant the drawings. Post spacing tolerances must not, however, become cumulative. Remove any old / unused fittings from fencing installations.

Maintenance Repairing damaged galvanised coatings Damaged areas of galvanised protective coatings can be repaired by removing any rust from the steel and applying of a 150 micron coat of zinc enriched spray paint. This procedure complies with EN ISO 1461, 1999 clause 6.3 and does not apply to components that are damaged or thinned in such a way as to affect their integrity should an impact occur.

Routine Inspection For the Highway England network, a weekly drive - past conducted by the ISU crews will highlight unreported impact damage. More frequent inspections may be needed in areas of high risk and if so, these should be dealt with on a local basis. Detailed inspections on foot should be undertaken every 5 years for systems less than 10 years old, for older systems a 2 yearly check should be conducted in order that instances of significant corrosion can be noted and acted upon. For other roads, an inspection should be carried out in accordance with the Local Authorities standing procedure but should not exceed 6 monthly. For other roads, an inspection should be carried out in accordance with the Local Authorities standing procedure but should not exceed 6 monthly.

Repair The straightening of damaged components is not allowed and such components will be replaced. All fasteners in the area of the impact shall be replaced with new fasteners irrespective of their apparent condition.

A check / inspection of the system, either side of the area of impact will be conducted to ascertain if further damage has resulted. If damage is seen, or suspected, then the area of repair should be extended to encompass this. Posts in this area should be inspected with the inclusion of the anchorage. If the anchor has failed or is suspected of having failed, a test should be conducted in accordance with Anchor Testing Method & recorded on GQF-54 Iss2 June 09 to ascertain if anchor replacement is required.

Where fasteners at damage interface are found to be problematic at the time of replacement, suitable means shall be employed to remove the offending fixing in such a way as to ensure that where possible the undamaged components remain serviceable
