Construction site planning: definition, tasks and practical examples
What is construction site planning?
Construction site planning encompasses the organisational, temporal and spatial planning of all work and resources required to carry out a construction project. This includes, amongst other things, staff, machinery, vehicles, equipment, materials, deadlines and individual construction phases.
The aim of structured construction site planning is to ensure that all parties involved and all resources are available at the right place at the right time. This is intended to prevent delays, double bookings, downtime and unnecessary costs.
Construction site planning does not begin only when construction work starts. It begins as early as the work preparation stage and continues throughout the construction project until completion and handover.
With a digital site planning Construction companies can use it to visualise and coordinate ongoing and planned construction projects together with the required resources.
What tasks are involved in construction site planning?
The tasks involved in construction site planning vary depending on the type and size of the construction project. The most important areas include:
- Organisation of construction phases and work stages
- Scheduling for individual trades
- Staff deployment planning for employees and teams
- Equipment deployment planning for construction machinery and tools
- Machinery scheduling across multiple construction sites
- Coordination of vehicles and transport operations
- Planning of material deliveries
- Coordination with subcontractors
- Taking qualifications and authorisations into account
- Monitoring of construction progress and deadlines
- Adjusting the schedule in the event of disruptions or delays
When several construction projects are running simultaneously, a decision must also be made as to which resources are to be deployed at which construction site. In particular, specialist machinery, site managers and qualified skilled workers are often in short supply.
Which resources need to be planned on a construction site?
A construction site requires far more than just staff and materials. Depending on the construction project, various personnel, technical and logistical resources need to be coordinated.
Staff and Teams
Staff planning on a construction site includes, for example:
- Site manager
- Foremen
- Bricklayer
- Electrician
- Fitters
- Machine operator
- Security officers
- Skilled workers with specialised qualifications
- Subcontractors and external teams
When Staff deployment planning In addition to availability, working hours, qualifications, holidays, absences and legal requirements must also be taken into account.
Machinery and equipment
Equipment deployment planning and machine scheduling include, amongst other things:
- Excavator
- Cranes
- Wheel loader
- Lifting platforms
- Concrete mixer
- Special-purpose machinery
- Tools
- Measuring instruments
- Site huts
Machines must not be assigned to more than one construction site at the same time. In addition, transport times, maintenance, inspections and technical breakdowns must be taken into account. Further details on this can be found in the glossary for Machine planning.
Vehicles and Transport
Vehicles are required for the transport of staff, machinery and materials. These include:
- Transporter
- Lorries
- Trailer
- Service vehicles
- Crane vehicles
- Specialised transport
Co-ordinated vehicle planning prevents materials from arriving late or equipment from failing to be transported to the next construction site on time. The centralised planning of vehicles, drivers and assignments is also an important part of the Vehicle fleet planning and fleet management.
Materials and supplies
Material deliveries must also be coordinated with the progress of the construction work. If building materials are delivered too early, there may not be sufficient storage space. If they arrive too late, this results in downtime.
Typical materials and supplies include:
- Concrete and cement
- Steel
- Cables
- Pipes
- Insulation materials
- Components
- Prefabricated components
- Consumables
How does construction site planning work?
Professional construction site planning is usually carried out in several coordinated stages.
1. Enter the construction project and scope of work
First, the requirements of the construction project, the planned works, deadlines and general conditions are recorded. These include, for example, site development, excavation, structural work, traffic diversions, cable laying, interior fit-out and landscaping.
2. Define construction phases and dependencies
The construction project is divided into individual construction phases and work packages. It is important to clarify which tasks are interdependent.
For example, interior fit-out work cannot begin until certain structural works have been completed. Cable routing may need to be carried out before walls or ceilings are closed off.
3. Determine staffing requirements
For each construction phase, the system determines which staff members, teams and qualifications are required. This takes into account availability, working hours and existing assignments.
4. Assign machines and equipment
Machinery, equipment and vehicles are then allocated to the relevant tasks. Particular attention must be paid to resources that are shared across several construction sites.
5. Coordinate deliveries and external partners
Material deliveries, subcontractors, inspections and external services must be coordinated with the planned construction schedule.
6. Continuously update the plan
Construction site planning does not remain static throughout a project. Weather conditions, delivery problems, staff absences or technical faults may necessitate last-minute adjustments.
For this reason, the schedule must be regularly reconciled with the actual progress of the construction work.
A practical example of construction site planning
A construction company is managing three building sites simultaneously. Two site managers, several installation teams, a crane and two lifting platforms are required for the upcoming work.
The crane is already scheduled for the first construction site until Wednesday. However, the delivery of materials to the second construction site has been delayed. As a result, the installation date scheduled for that site cannot go ahead as planned.
With centralised site planning, the scheduler can see:
- which staff members are available on the new date
- when the crane can be moved to the second construction site
- whether a lifting platform can be used as an alternative
- what impact the postponement will have on the third construction site
- which teams and subcontractors need to be informed
The schedule can be adjusted before double bookings or unnecessary downtime occur.
The difference between site planning and construction schedule planning
The terms ‘construction site planning’ and ‘construction schedule planning’ are often used interchangeably, but they do not describe exactly the same thing.
Construction scheduling focuses primarily on:
- chronological sequence of the construction works
- Duration of individual operations
- Interdependencies between trades
- Milestones
- Completion dates
Construction site planning goes a step further. It also takes the following into account:
- Staff and Qualifications
- Machinery and equipment
- Vehicles
- Deliveries of materials
- Subcontractors
- several concurrent construction sites
- spatial and organisational conditions
Construction schedule planning is therefore an important part of overall site planning.
The difference between site planning and resource planning
Resource planning essentially deals with the availability and allocation of staff, machinery, vehicles and other operational resources.
Construction site planning links these resources to specific construction projects, construction phases, work sites and deadlines.
Example: Resource planning shows that an excavator is available on Thursday. Site planning specifies which construction site the excavator will be used on, what work will be carried out there and how transport will be organised.
The difference between site planning and project planning
The Project planning covers the planning and management of tasks, deadlines, resources and milestones within a project.
Construction site planning is a form of project and resource planning tailored to construction projects. It also takes into account construction-specific requirements such as trades, construction phases, site facilities, machinery, material deliveries, safety measures and changing work locations.
Common mistakes in construction site planning
Resources are being scheduled twice
A vehicle, a machine or an employee is accidentally assigned to several construction sites at the same time.
Qualifications are not taken into account
Although an employee is available, they do not have the necessary qualifications, authorisation or training for the intended task.
Transport and set-up times are missing
Machinery cannot be moved from one construction site to the next without taking time. Transport, assembly, set-up and testing must be factored into the schedule.
Material deliveries are not keeping pace with the progress of the construction work
Materials arrive at the building site too early, too late or in the wrong order.
Dependencies between trades are overlooked
The following tasks are being scheduled, even though the necessary preparatory work has not yet been completed.
Changes are not communicated centrally
Staff, site managers, planning staff and subcontractors work with varying levels of information.
Security measures are taken into account too late
Road closures, traffic diversions, inspections or special safety measures are not organised in good time.
Key figures for construction site planning
On-time delivery
Adherence to deadlines indicates whether construction phases and projects are completed within the planned timeframes.
Resource utilisation
Resource utilisation describes the extent to which staff, machines, equipment and vehicles are actually being used.
Downtime
Downtime refers to periods during which staff or machinery cannot be utilised due to a lack of materials, preparatory work or approvals.
Planning variance
The plan variance compares planned dates and workloads with the actual progress of the construction work.
Equipment availability
Equipment availability shows which machines and devices are available, reserved, in use, undergoing maintenance or faulty.
Staff capacity
Staff capacity shows which teams are working to full capacity and where there is spare capacity.
Re-planning effort
The re-planning effort captures how frequently and with what effort existing plans need to be amended.
Software as a support tool
Software can support construction site planning by providing centralised information on deadlines, availability, resources and responsibilities. The most suitable solution depends on the specific process, the available data and the existing systems. One example is Construction site planning with Visual Planning®.
Conclusion
Structured construction site planning links deadlines, construction phases, personnel, machinery, vehicles, equipment and deliveries into a single schedule. It provides clarity regarding dependencies and supports the coordination of several construction sites running in parallel.
