Plus Crash Pole Installation

Last wednesday night i went to Sungai Buloh Plus Toll Booth as one of Hilti's customer, Nakhoda Construction are installing crash pole at the toll booth. you see, recently, there was a lot of accidents happening and they are crashing to the toll attendant and actually when a 10 tonne lorry come crashing to the toll booth, the attendant have no chance to escape.
1. he was busy and focusly attending current highway user who are paying so he are not aware of danger incoming.
2. to up and run from the toll booth in a few second is quite hard to do. the booth are small FYI.
so PLUS come with a solution, install a crash pole good enough to barricade the toll booth from potential danger. the fastening to the concrete structure was done with Hilti HSL Anchoring System.
The contractor using Hilti TE 70 Combi Hammer to drill the hole but bith a lot of reinforcement, they switch to Hilti DD EC 1 Diamond Coring Machine.
i'm there as Nakhoda encounter stuck core bit inside the concrete. this is a common problem as we never know what are we hitting inside the concrete.
I instruct them to put water hose inside the core bit and use a spanner to turn it side way until it can move. then only the removal can be done.
