• Use bolt setting templates to achieve the required positional tolerances.
• Check bolt positions against the steelwork drawing before the concrete pour.
• Protect all projecting bolt groups with impalement caps immediately after pouring.
• Guard bolt threads against damage from concrete, plant, and foot traffic.
• Survey bolt positions after the pour and record any deviations from design.
• Report positional errors immediately so remedial action can be planned early.
• Use approved chemical or mechanical anchors for post-fixed bolt installations.
• Grout beneath base plates to the specification using non-shrink grout products.
• Remove impalement caps only when the steelwork is ready to be erected.
• Torque HD bolts to the design requirement and record the results.

• DON'T leave projecting HD bolts unprotected at any time during construction.
• DON'T skip checking bolt positions before the concrete pour is carried out.
• DON'T allow concrete vibration to displace bolt groups from their set positions.
• DON'T force steelwork onto misaligned bolts; report the error for assessment.
• DON'T damage bolt threads by allowing concrete splatter or impact from plant.
• DON'T drill post-fixed bolts without confirming reinforcement positions with a scanner.
• DON'T grout base plates until the steelwork alignment has been approved.
• DON'T use non-approved anchor systems for post-fixed HD bolt installations.
• DON'T ignore bolt group trip hazards on foundations during general site access.
• DON'T assume bolt positions are correct without surveyed verification after pouring.
