Proposed Amendments

Backplate: In order to minimise the amount of steel cutting we are proposing to use 3m x 1.5m sheets of 5mm steel for the backplate/defence zone. We will be using 5 sheets which will cover an area of 7.5m (width) x 3m (height). This will leave an uncovered area of the back wall on each side of approximately 370mm.

Defence Zone: This will be of 4mm steel and will extend above the backplate by a further 625mm making the entire backplate/defence zone a total of 3.625m in height.

Horizontal Baffle: A baffle will be fixed in position at a point 12.5m from the firing point. The bottom edge of the baffle will be 2.35m above floor level and the top edge will be 3.6m above floor level. This will cover all angles at all sightlines above .85m not covered by the backplate in a vertical direction within the safety angle of 125 Mils. A steel supporting pillar will be fixed in the centre (between firing points) and will be covered in 2” of timber on the firing point side.

Vertical Baffles: Vertical baffles will be fixed to the firing point side of the second pillar down range from the back wall (at a distance of 17.7m from the firing point). On the left hand side the baffle will extend beyond the pillar by a distance of 630mm and on the right hand side it will extend 610mm from the pillar. Both baffles will be 3.6m in height, these baffles will cover the side walls and back wall (not covered by the backplate) within the safety angle of 70 Mils.

As a result of these baffles, no plating is required for the sidewalls, the ceiling and the backplate/defence zone beyond the new backplate/defence zone dimensions of 7.5m x 3.625m. The bullet catcher zone and the backplate will be as per your drawings saving that the backplate will be larger than set out in your drawings.
