A few days of bright sunshine earlier this week meant we could make a
jig to hold the holding down bolts in position and add the last half ton
or so concrete into the abutments. The polystyrene cones around the
bolts (to be removed once the concrete has set) allow for final
adjustments to the positions of the bolts to make sure they fit into the
base plates that the main beams will be fitted to. The voids left by
the cones will be filled with construction grout to hold the bolts
firmly in their final alignment. Much measuring, re-measuring and making
sure everything would stay in place was done before mixing the
concrete.
