# Turnkey Commercial Construction

> Turnkey commercial construction delivers a commercial building from groundwork to a ready-to-occupy handover under one contract, covering foundations, structure, masonry, finishes, facade, MEP and interiors. Its main advantage is that trade interfaces are planned on one programme, since most delays and disputes arise at handovers between separate contractors.

## What we deliver

**Commercial buildings from groundwork to handover** — foundations, structure,
masonry, finishes, facade, MEP and interiors delivered as a single turnkey scope.

Hagerstone describes this work as *from structure to splendour*: the same
organisation takes a building from its foundations to a finished interior. That
is what makes speed possible — the programme is planned end to end rather than
stitched together from separate contracts.

## Scope of works

| Stage | What we deliver |
| --- | --- |
| Planning | Programme, sequencing, procurement plan |
| Groundwork | Excavation, foundations, plinth |
| Structure | RCC frame or PEB, slabs, staircases |
| Masonry & finishes | Blockwork, plaster, flooring, painting |
| Envelope | Facade, glazing, cladding, doors and windows |
| Services | Electrical, HVAC, plumbing, firefighting, ELV |
| Interiors | Fit-out, joinery, furniture |
| Handover | Testing, snagging, documentation |

## What drives the cost

Building size and height · structural system — RCC or PEB · foundation type,
which depends on the soil · facade specification · MEP complexity · interior
specification · programme compression · site access and logistics.

## Where projects go wrong

- **Design not frozen before construction.** Every change during construction
  costs more than the same change on paper.
- **Soil conditions assumed.** Foundation design depends on a proper soil
  investigation.
- **Trades contracted separately.** The interfaces between them are where time
  and money are lost.
- **Long-lead items ordered late.** Facade, lifts and major MEP plant can govern
  the programme.
- **Approvals not in the programme.** Statutory clearances sit outside the site's
  control.

## Why Hagerstone

## Frequently asked questions

### What does turnkey construction include?

Everything from groundwork to a building ready to occupy — foundations and structure, masonry and finishes, facade, MEP services, and interiors — under one contract and one programme. The value is not only convenience: most delays and disputes on construction projects happen at the handover between separate contractors, and turnkey removes those handovers.

### How fast can a commercial building be built?

Our delivery model targets 60 days for end-to-end execution, and one client describes the entire building construction being completed within 60 days. Achievable speed depends on the building's size and complexity, design freeze, approvals and material procurement — a building where those are settled before site work starts moves far faster than one where they are resolved as it goes.

### Why use one contractor for civil, facade, MEP and interiors?

Because the trades depend on each other. Structure determines where services can run; the facade depends on the slab edges; interiors depend on the MEP. When one team plans all of them, the openings, the tolerances and the sequence are resolved on the drawing. When they are separate, they are resolved on site, at the client's cost.
