Excavation projects—whether for driveways, site prep, drainage, or grading—require careful preparation to ensure smooth, safe, and efficient work. Proper preparation prevents delays, protects your property, ensures contractor safety, and can even reduce costs. This guide walks you through everything you should do before your excavation contractor arrives.
At Taylor Creek, we've completed thousands of excavation projects. We've learned what preparation makes the biggest difference. Follow these steps to set up your project for success.
1. Call 811 to Locate Underground Utilities
Why This Is Critical
Before ANY digging occurs, you must call Washington Utilities Locating Service (811) to have underground utilities marked. This is free and mandatory. Hitting a gas line, electric cable, water main, or sewer can cause injury, death, property damage, and legal liability. It's not optional.
How to Call 811
- Call 811 at least 2–3 business days before digging
- Provide your address and description of planned work
- Utility locators arrive within 2–3 days to mark lines with paint or flags
- Marks remain visible for 30 days; request re-marking if work is delayed
Share the Markings With Your Contractor
After utilities are marked, take photos and share them with your contractor. Have the contractor confirm they've noted all marked utilities before starting work. If markings fade, request re-marking.
Key Point: If a utility is hit despite proper marking, the contractor's insurance covers damage (typically). But if you didn't call 811, you are liable. Always call 811 first—there's no exception or shortcut.
2. Clear the Work Area
Remove Vehicles
Move all vehicles from the work zone and surrounding areas. Excavation equipment is large and needs clear, unrestricted access and maneuvering space. Park cars at a neighbor's location if necessary. Inform your contractor where you've parked. Remove parked vehicles before crews arrive each morning if work spans multiple days.
Remove Personal Items and Obstructions
- Yard decorations, planters, lawn furniture
- Trash cans, recycling bins, mailbox (if in work zone)
- Garden hoses, extension cords, outdoor equipment
- Ladders, scaffolding, or stored materials
- Anything that could be damaged or interfere with work
Clear Vegetation and Landscaping
Discuss with your contractor what vegetation should be removed. For driveway excavation, remove low-hanging branches that could snag equipment. If trees near the work zone are to be protected, mark them clearly and discuss protection measures with the contractor (flagging, signage, etc.).
3. Inform Neighbors and Plan for Noise/Dust
Notify Neighbors in Advance
Let neighbors know excavation work is coming. Provide approximate dates and duration. Explain that there will be noise, dust, and occasional heavy traffic from equipment and dump trucks. Professional courtesy prevents complaints and maintains goodwill.
Plan for Dust and Debris
Excavation generates dust. Close windows during work hours. If you have HVAC, run it to pressurize your home and minimize dust entry. For extended projects, consider protective measures like tarps on nearby structures or dust control watering (which contractors can implement).
Plan for Access
Ensure contractors have clear access to the site. If driveway gates are locked, provide a code or contact number. If street parking is limited, discuss where equipment and worker vehicles will park. If your neighborhood requires permits for temporary construction parking, verify these in advance.
4. Document Current Conditions
Take Before Photos/Video
Photograph the entire work area from multiple angles. Document your driveway, yard, structures, and landscaping. This protects you in case of disputes about damage. If something is damaged during work, photos prove the contractor is responsible, not pre-existing conditions.
Document Existing Utilities and Infrastructure
Photograph visible utility boxes, meter locations, septic systems, well heads, or drainage features in the work zone. Confirm these locations with your contractor and discuss how they'll be protected.
5. Confirm Project Scope and Timeline
Review the Contract and Scope
Ensure your contract clearly specifies:
- Exact work to be performed (excavation, grading, removal, etc.)
- Materials to be removed and how they'll be disposed
- Materials to be left on-site (if any)
- Work schedule and expected timeline
- Site cleanup expectations at project end
- Protection of structures, utilities, and landscaping
Confirm Project Timeline
Excavation is weather-dependent. Rain delays work in the Pacific Northwest. Confirm a realistic timeline and expected completion date with your contractor. Ask how weather will affect the schedule and whether work will continue in light rain.
Discuss Equipment Access and Parking
Understand what equipment will be on-site (excavator, dump trucks, grader, etc.) and its size. Confirm where equipment will be positioned and how long it will stay. Know the daily work hours (typically 7am–4pm on weekdays; clarify if weekend work is planned).
6. Prepare Access for Equipment
Clear Driveway and Pathways
If excavation requires truck access through your driveway or side yard, clear any low-hanging branches, gates, or obstructions. Some driveways can't support heavy equipment—discuss this in advance. If reinforcement is needed, address it before work starts.
Secure Fragile Structures
If excavation is near a deck, patio, or detached structure, discuss protection. Contractors may install warning tape or barriers to prevent accidental damage. Verify these precautions before work begins.
7. Protect Utilities and Systems
Shut Off or Protect Utilities if Needed
Depending on the project, you may need to temporarily shut off or protect utilities:
- Irrigation systems: Shut off and drain lines if excavation affects them
- Septic systems: Mark the tank and field; keep heavy equipment away
- Well systems: Mark the well head; keep it clear
- Electrical/gas: Discussed with contractor; utility markings show locations
Discuss Any Basement or Underground Access
If excavation is near your basement, crawl space, or underground structures, discuss access. The contractor may need to inspect underground elements or access them during work.
8. Plan for Final Inspection and Cleanup
Final Walk-Through
Before final payment, walk the site with the contractor. Verify all work is complete, the site is cleaned up, and no damage occurred. Take photos of the finished work. Document any incomplete work or concerns in writing before paying the final invoice.
Cleanup Expectations
Confirm that your contractor will remove all debris, equipment, and temporary materials at the end of each work day or upon completion. Discuss whether the property will be graded/finished or left raw, and whether additional work is needed to integrate with existing landscaping.
9. Arrange for Temporary Water/Power (If Needed)
Does Your Contractor Need Water Access?
Dust control and concrete work may require water. Confirm with your contractor if they'll need hose access. Agree on what water supply they'll use (your hose, a fire truck spray, purchased water, etc.).
Power for Tools
Most contractors bring portable power generators. Discuss whether they need access to an electrical outlet on your property. If so, designate a location and ensure adequate extension cords (OSHA-compliant).
10. Prepare for Contingencies
Ask About Unexpected Conditions
During excavation, unexpected rock, old debris, or utility conflicts might surface. Discuss in advance what happens if costs increase due to unforeseen conditions. Ensure your contract has a contingency clause and a process for approval before additional work is done.
Have a Communication Plan
Exchange cell phone numbers with your contractor. Confirm they have your contact info and your partner's (if applicable). Establish daily or as-needed check-in times. This prevents surprises and keeps projects on track.
