Page 4: Scope
Product Design, Warranty and Liability The product assurances given by SAFEROAD for design, warranty and liability for the MegaRail family of products will be invalidated if it is demonstrated that components have been used from an unapproved source in installation, maintenance or repair and if the VRS does not comply with SAFEROAD’s specifications. -
Page 5: Health And Safety
SAFEROAD’s Lantra Awards approved training centre. SAFEROAD’s training policy extends to anyone installing MegaRail from outside of the UK who already has MegaRail training and therefore these erectors must also have the LANTRA basic training for safety barriers and hold a Blue, Gold or Black CSCS / FISS card. -
Page 6: Containment Level
Revision 33 October 2022 In central reserves where there are two single sided safety barriers it must be ensured that the working width is maintained between the two. Note: For either of the above situations, a departure from standard must be obtained from the overseeing authority. -
Page 7: Vehicle Intrusion
Revision 33 October 2022 Vehicle intrusion Consideration must be given to the available space behind the VRS system to ensure that the errant vehicle does not strike the obstruction when the system is impacted. Although a system may have a working width of W2 ≥... -

Page 10: Visibility
CD109 (section 3) which has replaced TD 9. Sloping Ground The ground below the MegaRail shall be near level within the set back and working width as shown in CD377 figures 3.28 & 3.29. MegaRail height The MegaRail systems should be set to the heights shown on the drawings with a tolerance of plus or minus 50mm for all systems. -
Page 11: Length Of Megarail
Revision 33 October 2022 2.10 Length of MegaRail The minimum length of MegaRail required to meet the length of need FOR N2, H1 or H2 systems are shown on our drawing numbers MR-GA-042 & MR-GA-043. Where MegaRail is being erected between other VRS systems, for example between two parapets, the minimum length can be to suit the need. -
Page 12: Setting Out
It is the installers responsibility to ensure that they are working to the current manual and drawings. These can be found at www.saferoad.co.uk/products/safety-barrier/ 4.1 Setting Out Establish the length of need both in advance and on departure from the hazard excluding terminal lengths. Set out the post pitches ensuring that the length of need is covered. -
Page 13: Concrete Foundations
30 years. Saferoad have developed a driven foundation which can be driven as a post is but is used as a socket. It is soil tested to the same standards as a driven post. - Page 14 Revision 33 October 2022 The test foundation should be designed so that the risk of displacement under impact is avoided when struck at type test angle. (See section 7) • Establish post centres and excavate foundations to the size established. When constructing the foundations ensure there is a minimum of 100mm of concrete cover to the post socket (70mm on augured foundations).

Page 15: Surface Mounted Posts
Reinforcing should be designed in such a way that it is compatible with the use of SAFEROAD anchorage systems which is the preferred method of anchoring in a purpose-built foundation. However please note resin anchors can be used. -
Page 16: Steel Plate Foundation
Revision 33 October 2022 • Surface mounted posts should be manufactured to the correct height for the location the use of detachable height adjusters is not permitted. Steel Plate Foundation It is becoming increasingly common to install a conventional safety barrier across a structure in front of an existing parapet. -
Page 17: 5- Megarail Assembly
The system is innovatory designed to ensure there is no requirement for slack removal using tapered bars. The beams are fastened with MegaRail M16 lap bolts. For diameter of the post bolts and all torque settings refer to the MegaRail manual. -
Page 18: Mega Flex
Revision 33 October 2022 be tightened to between 70 and 140Nm. Post bolts should be tightened to between 70 and 140Nm. • When Mega Guard is installed as a safety barrier it may also be set in sockets. However, when used as a parapet system it may only be set on base plates. -
Page 19: Connection To Other Proprietary Vrs
500mm square x 900mm deep Connection to Other Proprietary VRS SAFEROAD have such confidence in the MegaRail family of products and their total compliance with EN 1317 that they are willing to allow connection to any other reputable EN 1317 system that has been correctly tested and where the promoters of that system confirm their product will perform correctly up to but not including the joint. -
Page 20: 6- Inspection Maintenance And Repair
Revision 33 October 2022 Inspection Maintenance and Repair Inspection One of the MegaRail inspection certificates shown below should be completed for each VRS fence and submitted to the client to confirm the system has been inspected and is certified as compliant. The installation must be checked and certified as compliant using the system drawings. -
Page 21: Maintenance
Revision 33 October 2022 Maintenance A correctly installed and certified MegaRail VRS is maintenance free for the period of its design life. A visual inspection regime is recommended to check for impact damage. Where this is identified, repairs must be carried out. -
Page 22: Ground Conditions
4/1. As a minimum SAFEROAD recommend that at least one test is carried out for each VRS run or one test for every 200m whichever is the greater. -
Page 23: Soil Test Criteria
Revision 33 October 2022 Soil test criteria Sigma 100 driven post, driven foundation and concrete foundation A bending moment of 6.5 kNm (6500Nm) must be achieved before the posts deflection exceeds 100mm. C 125 driven post, driven foundation and concrete foundation A bending moment of 8.5 kNm (8500Nm) must be achieved before the posts deflection exceeds 150mm. - Page 24 Revision 33 October 2022...
