Large infrastructure programmes are usually divided into clearly defined phases: development, design, construction, installation, commissioning and operations. Workforce planning, however, does not always follow the same logic.
Contracts end when construction packages are completed, external specialists leave and new teams take responsibility for the next phase. Although this can appear orderly on paper, it may allow valuable project knowledge to leave with them.
Planned redeployment – moving suitable specialists into the next delivery phase or another relevant project – protects that knowledge while improving continuity, productivity and workforce retention.
Why is so much project knowledge lost between construction and commissioning?
Because workforce transitions are often considered only when contracts are already approaching their end. Experienced specialists then leave before knowledge about decisions, deviations, interfaces and unresolved issues has been transferred. Earlier redeployment planning creates continuity and keeps essential knowledge accessible during the transition.
Documentation is essential, but it rarely captures the full history of a project. Experienced specialists know not only what was built, but why decisions were made, where temporary solutions were introduced and which risks remain unresolved.
If they leave before commissioning begins, the incoming team must reconstruct that context. This consumes time and increases the likelihood of misunderstandings, rework and delays.
What knowledge matters most during the transition?
The most valuable knowledge often sits outside formal drawings and systems: technical deviations, informal agreements, site-specific conditions, supplier decisions and known weaknesses. This context helps commissioning teams understand the installation, prioritise testing and resolve problems without repeatedly retracing decisions made during construction.
Energy, telecommunications and data centre projects generate numerous detailed decisions during delivery. Components may be adapted, programmes may change and interfaces may be installed differently from the original design.
The specialists involved in those decisions can often diagnose later issues more quickly than an entirely new team. Particularly valuable knowledge includes:
-
interfaces between technical work packages,
-
differences between design and installation,
-
outstanding defects and incomplete activities,
-
safety and site requirements,
-
supplier and subcontractor arrangements,
-
testing, acceptance and escalation procedures.
How does redeployment protect project continuity?
Redeployment retains selected specialists beyond the completion of their original assignment or moves them into the next phase in a controlled way. Their technical context and relationships remain available while the incoming team assumes responsibility and completes a structured handover.
Redeployment does not mean moving the entire construction team into commissioning. The objective is to identify the individuals whose knowledge will provide measurable value during the next phase.
A construction manager may support the handover, an electrical engineer may explain installation deviations, or a project manager may retain ownership of outstanding packages until final acceptance.
Even a limited overlap can make a significant difference when responsibilities, deliverables and timescales are clearly defined.
Which specialists should be considered for the next phase?
Priority should be given to people with critical interface knowledge, substantial delivery responsibility or a detailed understanding of technical deviations. This could include construction managers, project managers, electrical and mechanical engineers, HSE specialists, quality managers, commissioning engineers and specialists in control or building management systems.
The decision should not be based solely on job titles. The more important question is: which person holds knowledge that would be difficult, expensive or time-consuming to replace?
Useful selection criteria include:
-
knowledge of critical systems or work packages,
-
responsibility across several technical interfaces,
-
direct relationships with clients, suppliers or authorities,
-
awareness of deviations and unresolved risks,
-
performance and reliability during the current phase,
-
suitability for responsibilities in the next phase.
When should redeployment planning begin?
Planning should begin several months before the expected transition. This provides time to identify critical roles, review performance, confirm availability and discuss suitable opportunities. Organisations that wait until the final weeks may find themselves competing again for specialists who already understand their project.
In-demand project specialists plan ahead. Without visibility of a potential next assignment, they may begin searching before their current responsibilities have been completed.
Redeployment should therefore form part of regular workforce reviews. Project leadership, technical teams, HR, procurement and recruitment partners should jointly determine:
-
Which activities are genuinely ending?
-
Which knowledge will the next phase require?
-
Which people could be retained or redeployed?
-
Which engagement models are appropriate?
-
Where is an overlap period necessary?
How can organisations create an effective knowledge transfer?
Effective knowledge transfer combines documentation, direct handover and a defined overlap period. Important decisions, deviations, stakeholders and unresolved risks should be recorded clearly. Experienced specialists should also remain available for questions until the incoming team can confidently assume responsibility.
A handover must be more than a folder of documents. Joint site walks, technical reviews, outstanding-action registers and named owners create a more reliable transition.
A strong handover plan should cover:
-
critical systems and interfaces,
-
open actions and known risks,
-
important decisions and their rationale,
-
internal and external stakeholders,
-
required tests and approvals,
-
clear handover dates and responsibilities.
How can the right employment model support redeployment?
Freelance, labour-leasing and permanent hiring models offer different levels of flexibility, integration and long-term retention. The chosen structure must reflect the actual role and working arrangement. Reviewing it early supports both operational planning and compliant delivery.
Not every extension or redeployment should be handled in the same way. Clients must consider whether the specialist will continue performing the same task, become more closely integrated into the organisation or support a longer pipeline of projects.
The contractual structure, day-to-day working relationship and relevant legal requirements must align. In Germany particularly, engagement models should be reviewed carefully before an assignment is extended or materially changed.
How can RIZE protect knowledge across project phases?
RIZE helps clients identify critical specialists early, confirm their availability and plan appropriate next assignments. Through freelance, AÜG/ANÜ and permanent hiring solutions, project teams can be scaled for individual phases while retaining continuity across important transitions.
We support infrastructure projects across energy, telecommunications and data centres, from planning and construction through commissioning and operations.
Regular communication with clients and specialists allows us to identify approaching assignment end dates, assess future demand and prepare suitable options. Redeployment therefore becomes part of the workforce strategy rather than a last-minute response.
Conclusion
Project knowledge is an operational asset. Losing it between construction, commissioning and operations can create avoidable cost, delay and risk.
Organisations that plan redeployment early do more than retain information. They improve handovers, keep proven specialists engaged and create more stable project teams.
Are you preparing for the next phase of an infrastructure project?
RIZE can help you retain critical knowledge and secure the specialists needed for the next stage.
