Borehole and Water Works Project Quotation

What a good one includes

• Clearly state the mobilization and demobilization fees for transporting heavy drilling rigs, support vehicles, and crew to and from the site.
• Break down the drilling costs per meter or foot, specifying how the price adjusts if geological conditions require drilling deeper than anticipated.
• Detail the materials, diameters, and class of the PVC or steel casing and screens to be installed to prevent borehole collapse.
• Itemize the specific submersible pump model, motor control panel, piping, and wiring required to bring the water to the surface.
• Include dedicated line items for the 24-hour test pumping phase and laboratory water analysis to certify the well's safety and flow rate.
• Specify the concrete slab dimensions, wellhead cap, and sanitary sealing process to protect the aquifer from surface contamination.

Common mistakes to avoid

• Failing to include a contingency clause for difficult geological formations or hard rock layers that require specialized hammer drilling.
• Lumping labor, machinery, and material costs into a single sum rather than providing transparent, itemized line items.
• Omitting local environmental permitting fees and water authority licensing requirements from the initial cost breakdown.
• Neglecting to clearly define who is responsible for site restoration, mud pit cleanup, and the disposal of drilling spoils.
