Blast Hole Drilling Requirements

Blast hole project boundary

Identify the blast hole drilling work package and the professional responsible for approving its project requirements. Ask that person to provide the drilling brief suitable for an equipment enquiry. Distinguish the equipment purchase from other project activities and identify the owner of each scope boundary in the purchasing request.

State whether the request concerns a complete drilling package or equipment for an existing project team. List items already held by the buyer and ask which documents are required to review the proposed equipment scope. Refer questions about the wider project design to the responsible professional before changing the drilling brief.

Blast hole design records

Request the current designer issued drilling requirement documents and identify the revisions bidders should use. Ask the designer to mark the requirements relevant to equipment selection and to identify any questions still awaiting project approval. Keep the drawing references visible in the enquiry response sheet provided to bidders.

Ask the equipment reviewer which additional project documents are needed to assess a proposed drilling package. Request answers that refer to the submitted requirements rather than an unrelated equipment description. If the designer changes the drilling brief, identify the affected requirements and ask bidders to revise their equipment responses accordingly.

Blast site access information

Prepare a drawing showing the proposed equipment approach route and arrival area for the project. Ask the site contact to identify buyer known restrictions and the route information available for transport review. Request current photographs or additional sketches where the appointed planner needs a clearer description of the proposed access.

Ask bidders which transport arrangement drawings can be supplied for the site planner's assessment. Keep access questions distinct from equipment configuration questions and assign each to the appropriate project reviewer. Identify who approves the arrival arrangement before the purchasing team agrees the proposed receiving location and commercial transport responsibilities.

Blast drilling equipment scope

Create purchasing lines for the drilling equipment requested and identify the project owner responsible for reviewing each line. Separate associated equipment already held at the site from new purchases. Ask bidders to map their proposed items to that list and to identify items that require further clarification before quotation.

Request a separate description of additions suggested by the bidder and ask the technical reviewer to assess their relationship to the project brief. Keep alternatives on distinct commercial lines. Confirm buyer requested quantities, minimum order requirements and delivery arrangements before asking the purchasing team to approve the final equipment scope.

Blast drilling document review

Ask the appointed reviewer which equipment drawings and descriptions should accompany the proposal. Prepare a document request register that links each requested submission to a drilling requirement or purchasing line. Identify the person responsible for answering questions about the submitted equipment documents and the person approving any resulting project change.

Request a written response for equipment documentation still missing from the proposal. Ask bidders to identify the drawing revision addressed by each clarification. Refer proposed changes to the relevant project reviewer and record which submissions need further approval before the equipment offer can be assessed by the purchasing team.

Blast hole bid reconciliation

Compare proposals using the same drilling project brief, item list and designer issued drawing register. Ask bidders to identify unanswered questions and to explain differences against the submitted scope. Keep changes affecting the approved drilling requirements with the project professional responsible for deciding whether the change should be considered.

Track answers beside the original requirement and ask for revised replies if the project brief changes. Request a final equipment list separating requested items from proposed additions. Reconcile that list with the buyer's purchasing schedule and seek clarification of exclusions before the commercial reviewer prepares the equipment purchase for approval.
