Why this method statement is used

This method statement is used to define and communicate the approved procedure for carrying out method statement – installation of grass turf sods on site. It ensures the work is planned in advance, the correct resources and controls are in place, and all personnel understand responsibilities, sequence, quality requirements, and safety controls before work begins. It aligns site execution with the documented scope and acceptance expectations.

Who uses this method statement

This method statement is used by contractors, site supervisors, project engineers, QA/QC engineers, HSE officers, consultants, and client representatives. It serves as a shared reference for planning, execution, supervision, inspection, and approval of the activity on site.

When it is prepared and submitted

The method statement is prepared before the work activity starts and submitted as part of the pre-construction documentation package for review and approval.

Who reviews or approves it

The method statement is usually submitted to the client representative, consultant, resident engineer, or project management consultant for review and approval before the work commences.

Important approval note

This method statement is an AI-assisted editable starting point, not a pre-approved document. Before use on any project, all content must be reviewed and approved by the relevant parties (superintendent, principal contractor, or client representative) in accordance with your contract and project quality plan.

For example: if your specification requires a departure from a referenced standard, that departure must be documented and approved separately — this method statement will not capture that automatically. Always verify against your applicable drawings, specifications, and regulatory requirements.

Method Sequence

Step	Activity	Description	Responsibility	Inspection / Hold Point
1	Subgrade verification	Confirm formation is to level, drains installed/functional, no standing water. Remove debris/stones >50 mm. Confirm no over-compaction that prevents infiltration; scarify 50 mm if sealed.	Engineer/Contractor	Visual; infiltration spot check if required
2	Topsoil placement	Spread compliant topsoil to achieve 100–150 mm finished depth after settlement [Verify]. Avoid trafficking when wet. Stage placement to minimize compaction.	Contractor	Thickness checks (probe)
3	Soil amendment incorporation	Apply compost 20–40 mm and fertilizer per approved rates; incorporate to 100–150 mm using rotary tiller. Apply lime/sulfur/gypsum per lab recommendations.	Contractor	Visual; spreader calibration; application logs
4	Fine grading and consolidation	Rake to uniform plane; remove stones >20–30 mm at surface; lightly consolidate (foot tamp or light roller). Achieve smoothness and falls to drains.	Contractor	3 m straightedge
5	Moisture conditioning & pre-irrigation	Lightly water the bed 12–24 h prior to laying to reach 60–80% field capacity; ensure surface is firm but not tacky.	Contractor	Moisture meter/hand test
6	Sod delivery & storage	Schedule just-in-time deliveries. Offload onto shaded pallets or ground sheets; keep moist with fine mist. Lay within 24 h (preferably ≤12 h) of cutting.	Supplier/Contractor	Delivery inspection
7	Setting out and edge restraints	Snap lines; start along straight edge/kerb. Provide edge restraint at borders (flush kerb/edging).	Contractor	Line and level check
8	Laying pattern and jointing	Lay sod in staggered brick-bond pattern perpendicular to fall. Butt joints tightly (2–5 mm gaps), do not stretch. Stagger transverse joints ≥300 mm. On slopes lay perpendicular to slope with staples if >1V:3H.	Contractor	Continuous visual surveillance
9	Cutting and trimming	Cut around obstructions with sharp knife. Avoid small slivers <100 mm width; use larger pieces where possible.	Contractor	Visual
10	Light rolling for root-soil contact	Roll immediately after laying each area using 30–70 kg roller in two directions. Avoid ruts or squeezing joints.	Contractor	Visual; surface regularity
11	Initial irrigation (soak-in)	Apply water immediately after rolling to soak through sod and 100 mm of soil beneath. Typical 10–20 L/m² depending on soil and weather [Verify].	Contractor	Moisture probe at 100 mm
12	Joint topdressing (if gaps)	Brush in fine sand/soil mix into gaps up to 5 mm after initial watering.	Contractor	Visual
13	Establishment irrigation schedule	Days 1–14: Keep sod and top 50–75 mm moist; 2–3 light irrigations/day avoiding runoff. Days 15–28: Reduce to 1x/day or every other day, deeper soaks to encourage rooting. Adjust to climate and soil [Verify per project specifications].	Contractor	Moisture checks; visual stress signs
14	Traffic restriction and protection	Exclude traffic for minimum 14 days; use barricade tape/signage; boards for access as required.	Contractor	Site walkdowns
15	First mowing	When grass height reaches 50–60 mm, mow to 35–40 mm (remove ≤1/3 of leaf blade). Use sharp blades; collect clippings if excessive.	Contractor	Measure sward height
16	Post-lay fertilization (if specified)	Apply light N (e.g., 10–20 g/m² of slow-release N) at 3–4 weeks if growth is pale/slow [Verify]. Water-in.	Contractor	Spreader calibration
17	Rooting and adhesion check	At 10–14 days perform gentle tug test at random points.	Engineer/Contractor	Tug test
18	Final inspection and handover	Confirm surface regularity, joint closure, uniform color, no weeds/pests, functional irrigation coverage. Provide O&M and watering regime.	Engineer/Contractor	Joint walkdown

Fertilizer and chemical stewardship
Apply at agronomic rates; keep off hardscape; sweep granules immediately; maintain buffer from water bodies per local rules [Verify]. Store under cover with spill kits.
Material sustainability
Prefer peat-free compost; source sod locally where possible; recycle pallets and plastic wraps. Dispose of waste sod/soil at licensed facilities.
Noise and working hours
Restrict mowing and powered equipment to permitted hours; use well-maintained, quieter equipment.
Biodiversity and invasive species
Inspect sod for invasive weeds; reject contaminated loads; remove and bag weeds if identified.
Fuel and oil management
Refuel off vegetated areas; use drip trays; keep spill kits available; report and clean any spills immediately.
Dust suppression
Lightly moisten dry topsoil during grading; avoid excessive water causing runoff.

Frequently asked questions

Provide 100–150 mm finished depth of compliant topsoil after settlement, verified per project specifications and BS 3882.

Lay turf within 24 hours of cutting, preferably within 12 hours. Keep turf cool, shaded, and moist before laying.

Lay in a staggered (brick-bond) pattern, joints butted tightly with gaps 2–5 mm, perpendicular to the fall. Anchor on slopes >1V:3H if required.

Irrigate immediately after rolling to wet through the sod and 100 mm of underlying soil, typically 10–20 L/m² depending on conditions [Verify per project].

Perform the first mowing when the grass reaches 50–60 mm height, cutting to 35–40 mm with sharp blades and removing no more than one-third of leaf height.
