For commercial new builds, refurbishments and extensions, the groundwork stage sets the pace for the entire project. Site preparation, drainage, foundations, surfacing, and service coordination all need to be carefully planned so the programme can proceed safely and efficiently.
N&G Groundworks supports commercial clients, main contractors, developers and project teams across Dorset, Somerset and Devon with practical, well-managed commercial groundworks. With multiple disciplines handled under one package, projects can progress with clearer communication, better sequencing and fewer avoidable delays.
Starting with a clear site plan
Turning early information into a workable programme
A strong commercial groundworks package begins with a clear understanding of the site, the design intent and the practical constraints on the ground. Access, levels, existing services, drainage routes, ground conditions and programme milestones all shape how the works should be sequenced.
At N&G Groundworks, early planning helps turn drawings and site information into a practical delivery plan – giving contractors and project managers a clearer view of how plant, labour, materials and inspections will be coordinated from the start, helping the wider build programme move with more confidence.
Preparing the ground for construction
Earthworks that support the next phase
Before foundations, drainage, or external areas can be delivered, the site needs to be properly prepared. Earthworks can include site clearance, reduced-level excavation, bulk excavation, soil management, remediation, and the shaping of land to suit the proposed development.
On commercial projects, it’s a fundamental stage that requires precise control of levels, materials, and work areas. Poor preparation can create problems further down the line with drainage falls, floor levels and access routes. N&G’s team works carefully from agreed plans and datums, creating a stable, organised site that gives follow-on trades the conditions they need.
Managing drainage and water flow
Systems designed for performance and compliance
Commercial sites need effective water management from the outset. Foul & surface water drainage must be planned around levels, loading, maintenance access and the long-term use of the site. This can include private drainage, site-wide systems, attenuation, gullies, manholes and connections into wider networks.
Where public sewer connections are required, N&G can also support Wessex Water-approved sewer requisitions. Coordinating drainage early helps prevent clashes with foundations, roads, utilities and finished surfaces, while supporting a safer, more reliable system once the site is operational.
Building strong foundations and sub-structures
Accurate construction up to DPC level
The quality of the sub-structure directly impacts the rest of the build. Foundation construction needs to reflect the ground conditions, structural design and load requirements of the building, with accurate excavation, reinforcement and concrete placement throughout.
N&G also deliver sub-structure blockwork and brickwork up to DPC level, providing commercial buildings with a reliable base for the stages that follow. Refurbishments and extensions can be especially sensitive, as new construction often needs to connect neatly with existing structures, services, and access constraints.
Coordinating services and utilities
Keeping essential infrastructure moving safely
Commercial developments often involve live services, new connections or diversions to suit the proposed layout. Utility diversions require careful planning, safe excavation, and close coordination with providers to ensure work can be carried out without unnecessary disruption.
N&G’s experience across gas, water and electric mains helps project teams manage these interfaces more clearly. Early identification of service routes can also reduce late changes to drainage, foundations and surfacing. For contractors and commercial managers, this makes the overall programme easier to control and helps reduce risks around critical infrastructure.
Completing roads, surfaces and external areas
Durable finishes for daily commercial use
Once below-ground works are complete, external areas need the same level of care. Asphalt surfacing & external finishings can include roads, car parks, forecourts, footpaths, kerbs, driveways, yards and other high-use spaces.
Areas need to look tidy, drain properly, and withstand regular traffic. N&G manage the preparation, base construction, edging, surfacing and final finishes so external areas are ready for practical use. Where developments connect to adopted highways, Section 38 & 278 works may also be needed to support safe, compliant access.
Bringing the groundworks package together
N&G Groundworks work with contractors, developers, commercial managers and project teams across Dorset, Somerset and Devon, supporting projects where safety, programme control and quality need to be handled carefully from the ground up. If you are planning a commercial new build, refurbishment or extension, early input from an experienced groundworks team can help.
