Several steel beam guiderail spec/drawings and two new small sign support drawings. There are 16 new drawings, plus an updated version of OPSS.PROV 721 and CAIS 741.

Proposal details

Thrie beam structure connection – Five new MTODs for a new, non-proprietary thrie beam transition between steel beam guide rail and a concrete parapet wall. Long-span structure connection – Four new MTODs for a new, proprietary thrie beam transition between steel beam guide rail and a concrete parapet wall. Reduced deflection steel beam guide rail – Three new MTODs for a new, non-proprietary reduced deflection steel beam guide rail treatment. Guide rail treatment uses a continuous hollow structural steel tube in place of offset blocks between posts and W-beam. Ram Shield steel beam guide rail – Two new MTODs for a new, proprietary blockless steel beam guide rail system. Replaces existing ACP Sentry guide rail system which is no longer available. Ecoposte sign support – One new MTOD for a new, proprietary small sign support. Telespar small sign support – One new MTOD for a new, proprietary small sign support. OPSS 721 – Update to OPSS to introduce a new tender item for adjustment and rail replacement for existing steel beam guide rail with steel posts. Also introducing a new tender item for proprietary steel beam guide rail post cover. CAIS 721 – Administrative update to reflect changes to OPSS 721.
