Site Preparation & Earthworks
ARN Projects, led by founder Arron Dewhurst, treats the ground beneath every new home as the most critical component of the build. Before a brick is laid, the site must be made safe, stable and service-ready. This pillar page explains how the team delivers land clearing, grading, drainage, excavation, utilities and site logistics with the precision and care that protects your programme, budget and future asset value.
Clear objectives, clean site
Every successful build begins with a sharp brief. ARN Projects starts with topographical surveys, ground investigation reports and utilities searches to understand levels, soil classification, groundwater behaviour and service constraints.
With a site-led custom home construction, measurable targets are set: platform tolerances, compaction densities, drainage falls, haul routes and a phased logistics plan. The outcome is a site that’s safe to work on, compliant with UK regulations, and primed for efficient construction.
Land clearing that respects your programme and the environment
Vegetation clearance, stump removal and demolition are carried out under ecological checks and relevant permits. Trees with TPOs are protected, habitats are surveyed, and invasive species, for example Japanese knotweed, are managed via approved methods. Waste is segregated, with arisings recycled wherever possible.
Where buildings are removed, the team completes asbestos surveys and soft strip, then crushes inert rubble for reuse as certified Type 1, reducing lorry movements, cost and carbon.
Grading and levels: getting the platform right first time
A precise formation level saves you money later. Using GPS machine control and total station setting out, ARN Projects executes bulk earthworks, cut-and-fill and regrading to achieve design levels within tight tolerances. Weak soils may receive improvement via lime or cement stabilisation.
Where required, geogrids and geotextiles are installed to spread loads and control differential settlement. The finished platform is laser-checked before handover so downstream trades can start without rework.
Drainage design that actually works on a British site
Rainfall, fall lines and soil infiltration define how a plot behaves. ARN Projects integrates drainage strategy early, combining engineered falls, trench drains, French drains, permeable sub-bases and SuDS, for example soakaways, swales, attenuation crates or tanks, to manage storm-water on and off the site.
Percolation tests inform soakaway sizing; CCTV drain surveys verify existing runs. Silt fences, wheel-wash systems and settlement tanks prevent pollution and track-out. The result is a dry, workable site in winter and a home protected from water ingress for decades.
Excavation and foundations: safe, accurate, certified
Whether it’s strip, trench-fill, rafts or piled solutions, excavation is planned with temporary works in mind. The team prepares RAMS, adopts correct benching or shoring, and monitors groundwater. Bearing strata are inspected and signed off before concrete. Where contamination is suspected, soils are tested against Category A, B and C reuse criteria, with appropriate muck-away or remediation.
For retaining walls, basement excavations or steep plots, ARN Projects coordinates with structural engineers to integrate drainage blankets, weep holes and waterproofing details that stand the test of time.
Services and utilities: future-proofed from day one
Early coordination of utility routing and first-fix service planning, avoids costly clashes later. ARN Projects plans service corridors, service depths and separation distances to comply with UK utility standards. Ducts for electricity, gas, water, telecoms and fibre are installed with draw ropes, marker tape and compliant bends, ready for utility providers to connect.
External works, kerb lines, driveway sub-bases, inspection chambers, stop taps and meter boxes, are set out to exact levels so reinstatement is seamless and final surfaces drain correctly.
Site logistics that keep trades moving
A tidy, well-organised site builds faster. From the first day, you’ll see compounds set, welfare connected, haul roads laid and traffic management installed. Delivery slots, crane locations, lay-down areas and skip positions are mapped to reduce double handling.
One-way systems minimise reversing; banksmen and segregated walkways keep operatives safe. Materials flow efficiently, trades work without conflict, and neighbours see a professional operation, not chaos.
Quality control you can measure
Compaction is verified with in-situ testing, for example CBR, plate load or nuclear density as appropriate. Drainage gradients are checked, chambers are water-tested, and as-built surveys capture final levels.
Concrete cube tests and foundation sign-offs are filed for your records. Every stage is photographed and documented, forming a clear audit trail for warranty providers, Building Control and insurers.
Regulatory compliance, built in
CDM regulations, local authority requirements and environmental obligations are woven into the plan, not treated as an afterthought. Expect method statements tailored to the plot, utilities search results logged and briefed, temporary works designed by competent engineers, and environmental controls maintained.
If the planning consent includes SuDS, landscaping or archaeology conditions, ARN Projects sequences works to discharge them without derailing the programme.
Risk removed before it becomes cost
Sustainable earthworks that save carbon and cash
Smart material management turns spoil into asset. Reuse is prioritised: topsoil is stripped, tested, stockpiled and re-laid; crushed concrete becomes capping; clay is balanced across the site where feasible.
When export is unavoidable, haulage is scheduled efficiently and disposal is to licensed facilities with full waste transfer notes. Less transport, fewer imports, lower embodied carbon, without compromising performance.
Communication that keeps you in control
You’ll get straight answers, short progress updates, and clear look-aheads: tomorrow’s deliveries, next week’s inspections, the path to the next milestone.
Variations are flagged early with options and cost clarity. When the platform is ready, you won’t just be told, it’ll be proven with test results, as-builts and a clean, well-organised site.
From ground to go-live: the handover you want
When ARN Projects hands over, you receive a clean platform, verified falls, installed ducts and chambers, compliant temporary works removed, and a documented pack that satisfies Building Control and warranty providers.
Bricklayers, timber frame crews and M&E teams arrive to a site that’s ready, safe and set up for speed.
Frequently Asked Questions
How long does site preparation usually take?
Timescales vary with plot size, soil conditions and drainage complexity. A straightforward single plot with modest cut-and-fill and standard drainage might be ready in two to three weeks. Complex sites with stabilisation, attenuation tanks or retaining structures can require several additional weeks. ARN Projects provides a schedule up front and updates it as works progress.
Can poor ground be made suitable without piling?
Often, yes. Options include lime or cement stabilisation, over-excavation and engineered backfill, geogrid reinforcement or switching to a raft foundation. ARN Projects will recommend the most cost-effective route after reviewing your site investigation results.
What if the site floods or holds water?
A robust drainage strategy solves this. SuDS features, soakaways, swales, permeable sub-base, graded falls and perimeter drains move water away from structures. Where infiltration is poor, attenuation and controlled discharge to a surface water sewer may be used, subject to approvals.
Do I need to arrange utility connections myself?
ARN Projects installs service ducts and chambers and can coordinate with utility providers for quotations, wayleaves and connection dates. Early planning is essential to keep the build on programme.
How is quality verified?
Compaction tests, foundation inspections, drainage testing and as-built surveys provide objective evidence. You receive a documentation pack at handover for Building Control and warranty bodies.
