TOPIC: GETTING BUDGET & SCOPE READY (WITH SUBCONTRACTORS)
Purpose: To help Project Managers develop an accurate budget and a clean, subcontractor-ready scope package for the earthwork phase—removing ambiguity, preventing disputes, and setting predictable cost expectations from day one.
1. GATHER ALL REQUIRED DOCUMENTS BEFORE BUILDING THE SCOPE
☑ Latest civil plans (grading, drainage, utilities)
☑ Architectural plans showing pad elevations & footprint
☑ Current topographic survey or drone map
☑ Geotechnical/soils report
☑ Property boundaries, easements, and setbacks
☑ Any municipal grading requirements or conditions
📍 Your earthwork scope is only as accurate as the information you gather upfront.
2. DEFINE THE EARTHWORK SCOPE IN DETAIL (CLEAR FOR SUBS)
Identify every task the subcontractor is responsible for:
Site Prep & Clearing
☑ Clearing & grubbing
☑ Tree/brush removal
☑ Debris haul-off (if required)
Excavation & Grading
☑ Rough grade to plan
☑ Fine grade to tolerance
☑ Pad building & elevation setting
☑ Slab trench excavation
☑ Over-excavation (depth, limits, backfill responsibilities)
Import/Export
☑ Import fill (type, quantity, source)
☑ Export spoils (tipping fees, haul-off limits)
☑ Stockpile strategy (onsite vs offsite)
Utilities & Trenching
☑ Trenching depth/width guidelines
☑ Bedding, shading, and backfill requirements
☑ Temporary drainage or dewatering responsibilities
Compaction & Testing
☑ Who schedules soil tests
☑ Minimum compaction percent required
☑ What happens if a test fails (who pays, who reworks)
📍 Ambiguity in scope becomes change orders later—define everything now.
3. IDENTIFY SUBCONTRACTOR EXCLUSIONS (CRITICAL)
List what the earthwork subcontractor is NOT responsible for:
☑ Erosion control install unless specifically included
☑ Construction entrance / track out controls
☑ Survey staking and layout
☑ Utility locates
☑ Rock excavation (if separate rate applies)
☑ Hazardous soil removal
☑ Import material cost beyond allowance
📍 Exclusions are just as important as inclusions to prevent budget blowouts.
4. CONFIRM QUANTITIES BEFORE FINALIZING ANY BUDGET
☑ Cut/fill analysis completed
☑ Shrink/swell factors accounted for
☑ Export/import needs estimated realistically
☑ Trench lengths/depths confirmed
☑ Compaction lifts understood
☑ Retaining wall backfill quantities verified (if applicable)
📍 Accurate quantities = accurate budget. Never price earthwork off guesses.
5. IDENTIFY SITE CONDITIONS THAT AFFECT COST
☑ Existing slopes & grade differences
☑ Access constraints (tight lots, narrow driveways)
☑ Rock, hardpan, or large boulders likely onsite
☑ Water table or drainage problems
☑ Limited truck access or turning radius
☑ Weather seasonality (rain, freeze, mud)
📍 List every condition that could increase cost, and budget accordingly.
6. BUILD A CLEAN, SUBCONTRACTOR-FRIENDLY BUDGET
Include:
☑ Labor + equipment hours from subcontractor pricing
☑ Haul-off and dump fees
☑ Import material cost (with contingency for more loads)
☑ Testing agency fees
☑ Erosion control materials (if included)
☑ Mobilization/demobilization
☑ Fuel surcharges or trucking premiums
☑ Allowances for unknowns (rock, groundwater, etc.)
📍 A strong earthwork budget anticipates surprises and has controlled contingencies.
7. DOCUMENT ALL ASSUMPTIONS (MANDATORY FOR SUBCONTRACTS)
Examples:
☑ Access road is complete before earthwork mobilizes
☑ Site is clear of debris and obstructions
☑ All utility locates completed by GC before Day 1
☑ Soil conditions match the geotechnical report
☑ No rock excavation included unless priced separately
☑ Weather delays handled per subcontract terms
📍 Assumptions protect you during disputes—they must be written into the scope package.
8. ALIGN WITH SUBCONTRACTORS BEFORE FINALIZING
☑ Walk the site with the earthwork subcontractor
☑ Confirm they understand the scope line-by-line
☑ Review drawings together
☑ Ask subcontractor for clarifications or concerns
☑ Validate quantities or challenge unrealistic pricing
☑ Document all decisions in writing
📍 Alignment before pricing prevents arguments during construction.
9. CREATE THE FINAL EARTHWORK SCOPE PACKAGE
Include:
☑ Detailed written scope
☑ All exclusions
☑ Quantity takeoff summary
☑ Cut/fill analysis
☑ Erosion control requirements
☑ Compaction + testing requirements
☑ Site logistics and access plan
☑ Risk & assumption log
☑ Schedule expectations
☑ Latest plan set (civil, architectural, survey)
📍 This package forms the foundation of the subcontract and the budget.
EARTHWORK: BUDGET & SCOPE READINESS CHECKLIST
Before moving forward:
☑ Plans reviewed and understood
☑ Full scope defined in detail
☑ Exclusions documented
☑ Quantities verified
☑ Site conditions evaluated
☑ Budget complete with contingencies
☑ Assumptions documented
☑ Subcontractor alignment confirmed
☑ Final scope package assembled
✅ Once all items are complete, your earthwork scope is cost-controlled, clearly defined, and subcontractor-ready.
TOPIC: ONE WEEK BEFORE EARTHWORK STARTS (WITH SUBCONTRACTORS)
Purpose: To give Project Managers a clear checklist for everything that must be confirmed and coordinated with the earthwork subcontractor one week before they mobilize—so there are no surprises, excuses, or gray areas.
1. LOCK IN THE SUBCONTRACT & SCOPE
☑ Subcontract is fully executed (signed and returned)
☑ Final scope of work attached to the subcontract
☑ All inclusions, exclusions, and clarifications documented
☑ Unit prices (if any) are clearly listed (rock, export, extra trenching, etc.)
☑ Allowances or “T&M” items identified and capped where possible
📍 If it isn’t in writing, it will become a dispute later.
2. CONFIRM START DATE, DURATION & CREW SIZE
☑ Subcontractor confirms start date in writing
☑ Estimated duration for major milestones (rough grade, pad, trenches, backfill)
☑ Planned crew size and equipment list for Week 1
☑ Sub understands what “ready for you” means (permits, staking, locates done)
☑ Weather contingencies discussed (what happens if it rains before start?)
📍 No “I thought we were starting next week” conversations on your job.
3. MAKE SURE THE SUB HAS THE LATEST INFORMATION
☑ Most recent civil, grading, and utility plans sent
☑ Geotechnical report shared (and confirmed they’ve read it)
☑ Any revised pad elevations or grading changes communicated
☑ Existing conditions photos/notes sent if site was visited previously
☑ Site access map, parking, and truck route shared
📍 If the sub is working off old drawings, your budget is already at risk.
4. CLARIFY RESPONSIBILITIES & INTERFACES WITH OTHER TRADES
☑ Who is responsible for:
Erosion control install?
Construction entrance / tracking pad?
Temporary drainage or dewatering?
Trench backfill and compaction?
Import/export coordination?
☑ Confirm what is NOT the earthwork sub’s responsibility (so it doesn’t fall on the ground later)
☑ Identify handoff points with:
Utility contractor
Foundation crew
Concrete / flatwork contractor
📍 Defined edges of scope prevent “I thought they were doing it” moments.
5. UTILITY LOCATE & UNDERGROUND RISK EXPECTATIONS
☑ Confirm who calls 811 / public locates (you or the sub)
☑ Confirm who hires any private locator (sprinklers, old lines, etc.)
☑ Sub understands that no digging starts without visible marks on the ground
☑ Discuss procedure if unknown utilities are found (stop, notify, document)
☑ Clarify who pays for delays caused by unmarked/unknown utilities
📍 Utility hits are costly—everyone must know the rules before equipment moves.
6. SAFETY, INSURANCE & SITE RULES (WITH THE SUB)
☑ Subcontractor has provided COI (insurance certificate) meeting requirements
☑ License, W-9, and any required prequalification documents collected
☑ Site-specific safety rules provided (PPE, traffic, working hours, neighbors)
☑ Confirm they will conduct a daily tailgate safety meeting
☑ Emergency procedures and nearest hospital/ER shared
📍 You are still responsible for safety expectations—even with subs.
7. TESTING, INSPECTIONS & QUALITY EXPECTATIONS
☑ Confirm who schedules soil and compaction testing (you or sub)
☑ Testing agency contact shared with the sub
☑ Minimum compaction specs (e.g., 90%, 95%) clearly communicated
☑ Inspection sequence explained (rough grade, over-excavation, pad, trenches, etc.)
☑ Sub understands no covering work until inspections/tests pass
📍 Subs must know the standard you’re holding them to before they start the work.
8. LOGISTICS, STAGING & SITE ACCESS WITH THE SUB
☑ Staging area agreed on for:
Equipment parking
Soil stockpiles
Import material and rock
☑ Confirm truck route and turn-around locations
☑ Clarify neighbor sensitivity issues (noise, dust, traffic timing)
☑ Dust control expectations (water truck schedule, who pays?)
☑ Porta-john location and site facilities communicated
📍 The sub’s operation must fit your site plan—not the other way around.
9. CHANGE ORDER & COMMUNICATION PROCESS
☑ Sub understands no extra work proceeds without written approval
☑ Process explained:
RFI → Price → Written approval → Proceed
☑ Required documentation for extras (time, tickets, photos) laid out
☑ Main communication chain set:
Sub Foreman → Superintendent → PM
☑ Expectation set for daily or weekly progress updates
📍 Clear process = fewer surprise invoices.
10. FINAL “SUB READY” CHECKLIST (ONE WEEK OUT)
Before you say you’re ready for them to mobilize:
☑ Subcontract fully executed
☑ Scope, inclusions & exclusions clearly understood
☑ Start date and duration confirmed in writing
☑ Latest plans, surveys & geotech shared
☑ Utility locate responsibilities defined
☑ Safety, testing, and inspection expectations aligned
☑ Access, staging, and logistics discussed
☑ Change order & communication process agreed
✅ If all of this is done one week before the earthwork subcontractor starts, you’ve eliminated most of the reasons jobs start late, go sideways, or blow the budget in the dirt-moving phase.
TOPIC: THE DAY THIS PHASE STARTS (WITH SUBCONTRACTORS)
Purpose: To ensure the Project Manager leads a clean, safe, coordinated, and expectation-aligned start with the earthwork subcontractor on Day 1—eliminating downtime, confusion, and costly mistakes.
1. ARRIVE EARLY & PREP THE SITE BEFORE THE SUBCONTRACTOR ARRIVES

☑ Record crew size, equipment used, and hours worked
☑ Document any unexpected site conditions (water, rock, bad soil)
☑ Track trucking tickets for haul-off/import
📍 Documentation on Day 1 sets the legal & financial foundation for the whole phase.
9. SCHEDULE AND PREP FOR UPCOMING TESTING & INSPECTIONS
☑ Confirm when compaction tests will be needed
☑ Notify the testing agency of approximate timing
☑ Review compaction requirements with the foreman
☑ Ensure no areas are covered before testing passes
📍 Testing must keep pace with excavation or the job stalls.
10. END-OF-DAY WRAP-UP WITH THE FOREMAN
Before they leave the site:
☑ Review progress vs. expectations for Day 1
☑ Discuss any issues encountered (soil, access, utilities)
☑ Confirm the plan for tomorrow’s tasks
☑ Re-mark any disturbed stakes
☑ Ensure unsafe trenches or cuts are secured
☑ Document the day’s production and materials
📍 A clear end-of-day reset prevents confusion the next morning.

TOPIC: BEFORE YOU PAY (SUBCONTRACTOR PAYMENT RELEASE CHECKLIST)
Purpose: To ensure the Project Manager verifies work quality, quantities, documentation, and contract compliance before releasing any payment to the earthwork subcontractor—eliminating overbilling, disputes, and future corrective costs.
1. VERIFY WORK AGAINST THE SUBCONTRACT SCOPE
☑ Confirm all billed items match the contracted scope
☑ Check that no excluded work has been billed
☑ If billed for extras, confirm written pre-approved change orders exist
☑ Compare actual work completed to the scope line-by-line
☑ Ensure partial payments reflect true percent-complete
📍 Never pay for work that isn’t in the subcontract or isn’t actually done.
2. DOUBLE-CHECK QUANTITIES (CRITICAL FOR EARTHWORK)
For anything billed as cubic yards, tons, or truckloads:
☑ Verify cut/fill volumes using survey topo or drone data
☑ Confirm import/export quantities match signed trucking tickets
☑ Check number of loads hauled off vs. tickets and logs
☑ Validate trench lengths, depths, and widths against the plans
☑ Confirm rock quantities or “hard dig” hours are documented with photos
☑ Reconcile any differences between the subcontractor’s numbers and your records
📍 Earthwork is often billed by quantity—verify every yard, every load, every linear foot.
3. INSPECTIONS & TESTING MUST BE COMPLETE
☑ All required compaction tests are completed and passed
☑ Reports from the testing agency received and attached
☑ Any failed tests have documented corrections
☑ Inspector sign-offs (if applicable) are in hand
☑ Confirm no areas were covered prematurely
📍 You do not pay for untested or failed work. Period.
4. PHYSICAL SITE VERIFICATION WALKTHROUGH
Walk the site personally or with your superintendent:
☑ Rough grading matches plan elevations
☑ Pad elevation is accurate and level
☑ Slopes and drainage paths are installed correctly
☑ Stockpiles or spoils are handled per the scope
☑ All open trenches are properly backfilled (if included)
☑ No damage to protected trees, fences, sidewalks, or utilities
☑ Access road or track pad is in acceptable condition
📍 Your eyes on the site are the most valuable verification tool.
5. REVIEW CHANGE ORDERS (IF ANY)
☑ Confirm each change order was approved before work was performed
☑ Check that cost breakdowns match contract rates
☑ Validate material costs (receipts, supplier invoices if required)
☑ Confirm change orders include proper documentation (photos, notes, daily logs)
☑ Reject anything submitted after the fact without documentation
📍 Unauthorized extras are the #1 cause of payment disputes—control them tightly.
6. VERIFY DOCUMENTATION & PAPERWORK
☑ Subcontractor invoice matches contract terms
☑ Insurance is current (no expired COI)
☑ Lien release form prepared and accurate
☑ All daily logs submitted (if required)
☑ Trucking tickets, equipment logs, and load counts attached
☑ Any required as-builts or survey confirmations submitted
📍 Never pay without proper paperwork—this protects your project legally and financially.
7. CONFIRM NO OUTSTANDING DEFICIENCIES
☑ Walk outstanding punch items with the subcontractor
☑ Confirm corrections were completed
☑ Review notes from superintendent or quality inspector
☑ Ensure no safety violations or damage claims remain unresolved
☑ Verify erosion control remains intact and is maintained
📍 Never release payment while defects are unresolved—it removes leverage.
8. INTERNAL PM/SUPERINTENDENT ALIGNMENT
Before approving payment:
☑ Discuss completed work with your superintendent
☑ Validate field conditions match the subcontractor’s invoice
☑ Agree on percent-complete for progress billing
☑ Make sure field notes match subcontractor’s records
☑ Verify no open disagreements linger
📍 Your superintendent’s input is essential—they see the daily realities.
9. FINAL APPROVAL CHECKLIST BEFORE YOU PAY
☑ All billed work is complete and matches scope
☑ Quantities verified against tickets, logs, or surveys
☑ All tests passed and inspector approvals received
☑ No outstanding punch items
☑ Change orders valid and documented
☑ Paperwork complete (invoice, lien release, logs, etc.)
☑ Superintendent confirms accuracy
☑ PM confirms budget alignment
☑ Work quality meets project standards
10. PAY ONLY WHAT YOU CAN DEFEND
☑ If something cannot be verified, do not pay it
☑ If there are disputes, pay undisputed portions only
☑ Document any adjustments or withheld amounts clearly
☑ Send subcontractor a written explanation of discrepancies
📍 Good PMs don’t avoid conflict— they avoid paying for unverified work.

☑ Cover material placed gently and evenly
☑ Fabric fully buried—no exposed areas
☑ Final slopes and elevations confirmed
✅ When all items are complete, your geotextile installation is stable, compliant, and ready for long-term performance.
TOPIC: UTILITY PIPING (WATER / SEWER) — INSTALLATION, RULES & REGULATIONS
Purpose: To give project managers dependable, field-ready steps and compliance guidelines for installing water and sewer piping safely, correctly, and in accordance with codes and inspection requirements.
1. WHAT UTILITY PIPING IS DESIGNED TO DO (Simple Explanation)
Water and sewer piping systems:
Deliver clean water to the home
Carry waste safely away from the structure
Prevent leaks, backups, or contamination
Maintain proper slope for flow
Interface with city utilities and inspection requirements
📍 Think of utility piping as the job’s “lifelines.” If they’re sloped wrong, poorly supported, or damaged, the whole project is at risk.
2. INSTALLATION INSTRUCTIONS (Step-by-Step)
Step 1 — Layout & Confirm Alignments
☑ Verify pipe routes on the plan
☑ Confirm utility depths and horizontal clearances
☑ Call 811 for utility locates (required)
☑ Mark trench lines clearly with paint or flags
☑ Confirm connection points and elevations
Step 2 — Trenching
☑ Dig trenches to required depth and width
☑ Maintain separation from gas, electric, and storm utilities
☑ Maintain uniform trench bottom—no humps or dips
☑ Provide frost-depth protection where required
☑ Remove rocks, roots, and sharp debris
Typical depths:
Water: 18–36 inches (varies by region/frost line)
Sewer: 12–24 inches minimum, but depth driven by slope needs
Step 3 — Bedding Installation
☑ Install 3–4 inches of bedding sand or fine material
☑ Shape bedding to cradle the pipe evenly
☑ Do not set pipe directly on native soil or rock
☑ Smooth the bedding with a rake or screed board
Step 4 — Install the Pipe
Water Pipe
☑ Use HDPE, PEX, or Type K copper as required
☑ Lay pipe without kinks or sharp bends
☑ Install tracer wire on all non-metallic lines
☑ Use approved fittings rated for burial
Sewer Pipe
☑ Use SDR-35 or Schedule 40 PVC
☑ Ensure slope is correct:
2% (¼" per foot) recommended
1% (⅛" per foot) minimum
☑ Use long-sweep fittings, not tight 90s
☑ Install cleanouts where required by code
Step 5 — Connect Fittings & Components
☑ Use primer and solvent cement for PVC joints
☑ Use Fernco or Mission couplings when transitioning materials
☑ Avoid forcing pipe into alignment—adjust trench instead
☑ Confirm fittings are installed with correct orientation
Step 6 — Surround & Protect the Pipe
☑ Add 6–12 inches of approved material around pipe
☑ Hand-tamp lightly; do not compact with heavy equipment
☑ Keep rocks away from pipe bedding zone
Step 7 — Backfill the Trench
☑ Backfill in lifts no thicker than 6–8 inches
☑ Compact each lift to avoid future settlement
☑ Keep utility warning tape 12 inches above pipe
Step 8 — Testing & Inspection
Water Line Testing
☑ Pressure test to required PSI for required duration
☑ Flush line before connecting to fixtures
☑ Provide disinfection if required by jurisdiction
Sewer Line Testing
☑ Air test or water head test as specified
☑ Ensure all fittings and cleanouts remain accessible
☑ Maintain exposed pipe for inspector review
3. RULES & REGULATIONS TO CONSIDER
Building Code Requirements
☑ Water and sewer must be separated by minimum distances
☑ Slope requirements strictly enforced for sewer
☑ Cleanouts required every 100 feet (typical) or at direction changes
☑ Materials must meet local plumbing codes
☑ Proper bedding material required—no native soil with rocks
Municipal Utility Requirements
☑ Water tie-ins may require city utility crew
☑ Sewer mains must match invert elevations provided
☑ Permit must be active before installation
☑ Photo documentation often required
Inspection Requirements
☑ Pipes must remain exposed during inspection
☑ Proper slope and bedding checked
☑ Pressure test or air test required prior to approval
☑ Tracer wire must be visible and continuous
Safety Regulations
☑ Trenches > 4 feet deep require protective systems
☑ Ladders required for trenches deeper than 4 feet
☑ Spoils must be kept 2 feet from trench edge
4. BEST PRACTICES FOR FIELD SUCCESS
☑ Always start at the downstream end for sewer—gravity dictates everything
☑ Use a laser level, not eyeballing, for slope verification
☑ Keep the trench bottom smooth—pipe should never bridge or sag
☑ Pressure test before backfilling (avoid expensive dig-ups)
☑ Photograph all work for records and warranty protection
☑ Install sewer and water on separate trench lines whenever possible
📍 If slope, bedding, or alignment is wrong, the system will fail—fix it during install, not after inspection.
5. FINAL INSTALLATION CHECKLIST
☑ Routes marked and utilities located
☑ Trenches excavated to depth and width
☑ Bedding sand installed and shaped
☑ Pipe sloped properly and fully supported
☑ Fittings installed correctly
☑ Backfill placed in lifts and compacted
☑ Tracer wire installed (for water)
☑ Inspections passed
☑ Photo documentation completed
✅ When all items are complete, your water and sewer installation is safe, compliant, and reliable for long-term performance.
TOPIC: CLEAN FILL / IMPORT SOIL — INSTALLATION, RULES & REGULATIONS
Purpose: To give project managers clear, practical steps and compliance guidelines for placing imported soil or clean fill correctly—ensuring compaction, stability, and long-term performance for pads, utilities, and grading work.
1. WHAT CLEAN FILL / IMPORT SOIL IS DESIGNED TO DO (Simple Explanation)
Clean fill or import soil:
Replaces unsuitable native soil
Builds elevation for pads and grading
Backfills trenches and structural areas
Provides stable, compactable material for construction
Ensures soil meets engineering and compaction requirements
📍 Think of imported fill as the “corrected soil” that replaces what nature got wrong.
2. INSTALLATION INSTRUCTIONS (Step-by-Step)
Step 1 — Verify Soil Type & Moisture
☑ Confirm soil matches geotechnical requirements
☑ Check moisture content—soil must be workable
☑ Reject overly wet, clay-heavy, or contaminated loads
☑ Test soil with squeeze method or use a moisture meter
Step 2 — Prepare the Placement Area
☑ Remove organics, roots, trash, or debris
☑ Rough-grade the area for even distribution
☑ Proof-roll substrate to find soft spots
☑ Scarify surface if needed for bonding
Step 3 — Spread Fill in Thin Lifts
☑ Use equipment to spread soil in lifts no thicker than:
4 inches compacted for structural work
6 inches compacted for general fill
☑ Keep lifts consistent for even compaction
☑ Avoid large piles or deep dumps of soil
Step 4 — Moisture Conditioning
☑ Add water if soil is too dry
☑ Aerate by turning with equipment if too wet
☑ Aim for “optimal moisture content” per Proctor test
☑ Verify moisture content regularly during placement
Step 5 — Compact Each Lift
☑ Use plate compactor, jumping jack, roller, or trench roller
☑ Compact until soil is firm and stable
☑ Re-compact soft or pumping areas immediately
☑ Ensure each lift meets required 95% compaction (typical)
Step 6 — Repeat Lifts Until Final Grade Is Reached
☑ Continue spreading, moisture conditioning, and compacting
☑ Maintain consistent lift thickness
☑ Check grade frequently using laser level
Step 7 — Final Shaping & Verification
☑ Smooth final layer with skid steer or rake
☑ Confirm slopes direct water away from structures
☑ Prepare final surface for inspections or pad building
☑ Document each lift if required by geotechnical engineer
3. RULES & REGULATIONS TO CONSIDER
Geotechnical Requirements
☑ Soil type must match project specifications
☑ Moisture content must be within acceptable range
☑ Compaction must meet density requirements
☑ Test reports may be required at each lift
☑ Certain soils (high clay, organics) are prohibited
Building & Municipal Regulations
☑ Fill must be placed in controlled, documented lifts
☑ Clean fill must be free of hazardous materials
☑ Certain sites require import soil origin documentation
☑ Inspections may be mandatory before covering trenches or pads
Environmental & Safety Requirements
☑ Dust control required during placement
☑ Stockpiles must be protected with erosion control
☑ Truck routes often regulated by city permits
☑ Heavy equipment operators must follow trench safety rules
4. BEST PRACTICES FOR FIELD SUCCESS
☑ Always proof-roll before placing the first lift
☑ Reject any soil with excessive moisture or clay content
☑ Compact fill immediately—do not leave loose lift overnight
☑ Use imported soil consistently—mixing different soils causes settlement
☑ Keep records of load counts and soil source
☑ Take photos of each lift if inspection delays occur
📍 Most fill failures come from two issues: lifts too thick or moisture out of range—control these and everything succeeds.
5. FINAL INSTALLATION CHECKLIST
☑ Soil type confirmed and moisture checked
☑ Placement area prepped and proof-rolled
☑ Soil placed in controlled 4–6 inch lifts
☑ Moisture adjusted to optimal levels
☑ Each lift compacted properly
☑ Elevations checked regularly
☑ Compaction tests passed (if required)
☑ Final grade shaped and documented
✅ When all items are complete, your imported fill is stable, compacted, and ready for further construction.v
