Top hammer drilling brief
Identify the top hammer project task and the buyer's current hole requirement documents. Ask the project adviser which site and investigation records should accompany the rig request and name the person responsible for answering questions about the drilling brief.
Request a proposed equipment response linked to those project references. Keep changes suggested by bidders separate from the buyer's original requirement and ask the adviser who must approve an alternative before it can enter the purchasing comparison.
Top hammer rig arrangement
Ask the bidder to supply an arrangement description identifying the rig configuration and included equipment items proposed for the project. Send those documents to the buyer appointed reviewer and request a list of further submissions needed for assessment.
Keep the equipment drawing references visible in the enquiry response sheet. Ask for clarification if an offer describes an arrangement different from its accompanying drawing, and request revised documents where the proposed configuration changes during the purchasing discussion.
Tool and rig scope split
Prepare distinct purchasing lines for the rig and requested top hammer tools. Identify existing project tools separately and ask the appointed reviewer which item records are required to assess the proposed relationship between the rig and tooling requests.
Ask bidders to map proposed tools to those scope lines and identify alternatives separately. Refer questions about existing equipment records to the buyer's project contact and request written clarification of unmatched items before treating a package offer as complete for comparison.
Top hammer commercial comparison
Compare rig offers against the same drilling brief and equipment allocation schedule. Ask bidders to identify missing information and explain proposed scope differences, with technical questions assigned to the appointed adviser and commercial questions assigned to the purchasing owner.
Confirm the buyer requested quantities and minimum order requirements before ordering. Request written delivery arrangements and a final item schedule, then reconcile that schedule with the equipment proposal reviewed by the buyer's adviser before seeking purchase approval.
