Excavation Bid Proposal Template
Download an excavation bid proposal template to present trenching, earthwork, equipment, hauling, shoring, dewatering, exclusions, alternates, schedule, and project pricing.
Present Excavation Scope, Pricing, and Qualifications Clearly
An excavation bid proposal gives contractors a structured way to present mass excavation, trenching, foundation excavation, shoring, dewatering, bedding, backfill, hauling, disposal, equipment, restoration, alternates, exclusions, schedule assumptions, and commercial terms. It helps customers and general contractors understand the pricing basis while giving the excavation contractor a clear record of the work offered.
This Excavation Bid Proposal Template is designed for excavation contractors, earthwork subcontractors, site-development contractors, utility contractors, grading contractors, demolition contractors, civil subcontractors, estimators, project managers, and construction business owners.
What Is an Excavation Bid Proposal?
An excavation bid proposal is a customer-facing document that combines a defined excavation scope with proposed pricing and commercial terms. It may include mobilization, clearing, demolition, topsoil stripping, mass excavation, footing and foundation excavation, utility trenching, shoring, dewatering, bedding, backfill, imported fill, export hauling, unsuitable-soil removal, rock excavation, compaction, erosion control, restoration, testing support, cleanup, and closeout.
The proposal should explain what is included without relying on broad descriptions such as “complete excavation package.” It should identify the plans, specifications, geotechnical information, quantity assumptions, haul routes, disposal locations, shoring responsibilities, dewatering limits, and change procedures used to develop the price.

| Excavation Scope | Describes clearing, demolition, mass excavation, trenching, foundations, structures, pits, basins, undercut, and grading. |
| Shoring and Excavation Support | Identifies trench boxes, hydraulic shoring, slide rail, sheet piling, slopes, benches, access, inspections, and competent-person responsibilities. |
| Dewatering | Defines pumps, well points, bypass systems, hoses, discharge locations, filtration, permits, fuel, monitoring, and operating limits. |
| Materials and Backfill | Defines bedding, select fill, structural fill, aggregate, geotextile, flowable fill, imported material, compaction, and testing support. |
| Equipment, Hauling, and Disposal | Clarifies excavators, dozers, loaders, trenchers, pumps, compactors, trucks, haul routes, disposal facilities, borrow sources, and ticket requirements. |
| Pricing | Shows the base bid, alternates, allowances, unit prices, taxes, bonding, and optional work. |
| Assumptions and Exclusions | Clarifies utility locating, potholing, unknown utilities, unsuitable soils, rock, groundwater, contamination, survey, testing, restoration, and work by others. |
| Schedule and Closeout | Records mobilization, phasing, area releases, working hours, testing, restoration, punch-list, and closeout requirements. |
| Commercial Terms and Acceptance | Defines payment terms, retainage, proposal validity, change procedures, signatures, and accepted alternates. |
How to Use the Template
- Enter the excavation contractor, customer, project, proposal number, bid package, and recipient information.
- List the drawings, specifications, geotechnical report, addenda, RFIs, site visits, and clarifications used for pricing.
- Separate the work by area, phase, trench segment, structure, excavation type, material classification, and cost code.
- Describe clearing, demolition, excavation, shoring, dewatering, bedding, backfill, hauling, disposal, grading, and restoration.
- List the base bid, alternates, allowances, unit prices, and optional work separately.
- State assumptions for soil, groundwater, rock, unsuitable material, contamination, utility conflicts, haul distance, disposal, and borrow sources.
- Identify work by others, including survey control, testing, permanent power, utility relocation, traffic control, paving, landscaping, and environmental remediation where applicable.
- Record production, access, equipment, working-hour, phasing, weather, and area-release assumptions.
- Review payment terms, retainage, taxes, schedule, warranties, proposal expiration, and change-order procedures.
- Compare the customer-facing proposal total with the approved internal estimate before submission.
An excavation subcontractor prepares a proposal for a commercial utility package with 2,600 linear feet of sanitary and storm trenching, 18,000 bank cubic yards of mass excavation, imported bedding and backfill, trench boxes, groundwater pumping, 420 truckloads of export, pavement removal, compaction support, and restoration. Rock excavation, contaminated material, bypass pumping beyond the stated duration, and utility relocations are separated from the base bid and priced through unit rates or written change orders.
Best Practices for Excavation Bid Proposals
- Match the proposal to the latest civil, utility, structural, survey, and geotechnical documents.
- Organize the scope by area, trench segment, structure, excavation type, and phase.
- Identify whether quantities are bank, loose, compacted, tonnage, linear footage, or lump sum.
- Separate the base bid, alternates, allowances, and unit prices.
- Clarify utility locating, potholing, unknown-utility, and damaged-utility responsibilities.
- Define shoring, competent-person, access, slope, bench, and trench-inspection responsibilities.
- State groundwater, pumping, dewatering, discharge, filtration, and permit assumptions.
- Define rock, unsuitable soil, contaminated material, haul routes, disposal, and borrow-source procedures.
- Preserve every revision and identify what changed.
- Verify that the proposal total matches the approved estimate.
Common Excavation Bid Proposal Mistakes
- Submitting pricing based on outdated drawings or missed addenda
- Describing the scope only as a complete excavation package
- Failing to identify quantity basis or measurement method
- Leaving utility-locate, potholing, and unknown-utility responsibilities unclear
- Omitting shoring, trench access, competent-person, or inspection responsibilities
- Failing to define dewatering duration, discharge location, fuel, filtration, and permit responsibilities
- Ignoring rock, unsuitable soil, contamination, access, or disposal risks
- Combining base-bid work with alternates and allowances
- Submitting a revision without identifying changed scope or pricing
- Issuing a proposal that does not match the internal estimate
Frequently Asked Questions
What is the difference between an excavation estimate and an excavation bid proposal?
An estimate develops expected labor, equipment, materials, trucking, subcontractor, overhead, and selling price. A bid proposal presents the offered scope, pricing, assumptions, exclusions, schedule, and commercial terms to the customer or general contractor.
Should excavation quantities appear in the proposal?
Yes. Summary quantities help explain the pricing basis, especially for mass excavation, trenching, import, export, unsuitable soil, rock, bedding, backfill, and restoration.
How should trenching be described?
Identify the trench segment, station range, length, depth range, expected material, shoring method, bedding, backfill, dewatering, haul requirements, restoration, and measurement basis.
How should rock excavation be handled?
Define the criteria for rock, approved excavation methods, measurement procedure, equipment assumptions, disposal, replacement material, and applicable unit price or change-order process.
Should dewatering be included in the base bid?
Include it when the expected method, duration, flow, discharge location, permits, fuel, monitoring, and treatment requirements can be reasonably defined. Otherwise, use an allowance, unit rate, or clearly stated qualification.
What excavation alternates are commonly included?
Common alternates include rock excavation, unsuitable-soil removal, imported structural fill, alternate shoring systems, extended dewatering, night work, additional trucking, pavement restoration, and value-engineered excavation methods.
Should disposal and borrow sources be identified?
Yes. State the assumed haul distance, route, facility, acceptance requirements, tipping fees, borrow fees, payload limits, ticket requirements, and responsibility for rejected material.
When should an excavation bid proposal be revised?
Revise it when drawings, quantities, soil classifications, utility conditions, shoring, groundwater, haul routes, disposal sites, schedule, alternates, or commercial terms change. Preserve the prior version and document the revision.
