Sequencing
Check that access, phasing, logistics and testing needs are built into the installation plan before site work accelerates.
Delivery / 03
Installation & Commissioning
Supply, installation and commissioning support that protects design intent through procurement, energy-centre and network works, testing and handover.
Delivery brief
Installation decisions should protect commissioning, handover and long-term performance.
Heat network delivery risk appears when site sequencing, buried pipework, plantroom interfaces, access, testing, controls and handover evidence are treated as separate tasks.
DHS helps project teams keep design intent visible during installation and commissioning, so the network is not simply built, but tested, evidenced and prepared for operation.
Delivery decisions that matter
Delivery risk reduces when installation, testing and handover evidence are planned as one route.
Use DHS when the project is moving from design into site delivery and needs specialist judgement across sequencing, installation, commissioning and evidence capture.
Route installability
Review buried pipework, trench constraints, services interfaces, reinstatement and future access implications.
Plantroom interfaces
Coordinate plant, pipework, valves, controls panels, metering, access routes and maintainability.
Contractor coordination
Keep responsibilities, interfaces and issue resolution visible across civils, mechanical, electrical and controls teams.
Testing strategy
Protect pressure testing, flushing, water quality, metering checks and commissioning evidence from late compression.
Controls readiness
Make sequencing, control logic, weather compensation, metering and operator needs part of commissioning planning.
Resident impact
Identify access, phasing, heat continuity and communication risks before they become resident-facing.
Handover evidence
Build O&M, commissioning, metering, controls and operator-readiness evidence as the works progress.

Delivery evidence board
Site evidence should be built while the work is happening, not reconstructed at the end.
The useful record is practical: sequencing notes, issue logs, testing records, commissioning actions, controls evidence and handover material that supports operation.
- Installation plans checked against testing and commissioning needs.
- Site issues assessed against design intent and operating performance.
- Handover evidence assembled progressively, not retrospectively.
Delivery hold points
Protect the operating outcome while the work is still visible.
Networks often underperform because site changes, pressure to accelerate programme, weak commissioning evidence and incomplete handover information drift away from the design basis.
Before site start
Check access, phasing, interfaces, testing routes and evidence expectations before programme pressure rises.
Before pipework is closed
Capture route, jointing, pressure testing and buried-services evidence while it is still visible.
Before commissioning
Confirm plant, controls, metering, water quality and documentation are ready for meaningful testing.
Before handover
Protect operator readiness, O&M, commissioning records and performance-critical information.
Project-stage fit
Where installation & commissioning changes the outcome.
A delivery path that protects design intent, supports site coordination and gives testing, metering, controls and handover the attention they need.
Pre-start
Risk to sequence
A workable design can still fail on access, phasing, coordination or testing constraints.

Risk to protect
Site changes can weaken design intent if they are not assessed against performance and handover.

Risk to evidence
Testing can become compressed unless evidence requirements are visible before the final push.

Delivery FAQ
Common questions before bringing DHS into this workstream.
Practical questions clients ask before appointing specialist support for this workstream.
When should DHS support installation planning?
Before site start is ideal, because sequencing, access, testing and handover needs can still influence the plan. DHS can also support live delivery where issues need specialist judgement.
Can DHS help with commissioning evidence?
Yes. DHS can review commissioning planning, metering, controls, testing records and handover evidence so the project has a usable record for operation.
What installation risks are common on heat networks?
Common risks include route constraints, plantroom access, weak interface control, compressed testing, incomplete controls evidence and late handover documentation.
Does DHS work alongside contractors?
Yes. DHS can support clients and project teams with specialist judgement, coordination input and evidence review alongside the delivery team.
How does this support residents and operators?
Better sequencing, commissioning and handover evidence reduces the chance that technical issues become operational disruption or resident-facing performance problems.
