Construction planning

Construction planning describes a process in which a building project is conceptually developed and designed. These intellectual considerations are recorded in architectural and construction drawings . The form and properties of the local building site must be taken into account. The feasibility of the planning is proven in calculations. Construction planning is the first stage of the construction process , but is continued during construction . It is a prerequisite for the approval of a building project in Germany.

Construction planning types

There are roughly four types of construction planning:

Structural engineering
Civil engineering
Civil engineering, road and landscaping planning
Specialist planning

All of these areas are closely related to each other and are worked on by architects , civil engineers , landscape architects , draftsmen and specialist planners.

Construction planning regulations

Various legal and technical provisions must be observed during construction planning. The aim of establishing building regulations is to guarantee the safety and usability of the building project. The responsible planner has to consider the regulations, which are also called recognized rules of technology in the construction sector . Furthermore, compliance with regulations and laws ( e.g. building code , building regulations ) must be observed.

Planning phases

Service phases of property and specialist planning according to HOAI
LP1	Basic investigation
LP2	Pre-planning
LP3	Draft planning
LP4	Approval planning
LP5	Implementation planning
LP6	Preparation of the award
LP7	Participation in the award
LP8	Property supervision - construction supervision and documentation
LP9	Property management

The construction planning is divided into phases according to the HOAI : (depending on the complexity of the construction project, partial points may be omitted)

Basic investigation

During the basic determination, the task is clarified and the technical and economic fundamental questions of the project are presented. This phase of construction planning also includes a site inspection by the client and planner, whereby both the building site and the surrounding area are inspected. The results of the basic investigation are finally processed in a result presentation.

Pre-planning

The results of the basic assessment form the basis for the preliminary planning . In this phase of the construction planning, inquiries about the type of subsoil are made in order to create a planning concept and to discuss possible alternative solutions. The preliminary planning also includes an initial cost estimate for the construction project, which is regulated by DIN 276 . The information obtained from the preliminary planning is also recorded using a presentation of the results.

Draft planning

A calculation and design of the system is made during the draft planning. The project is implemented and described in a technical drawing on a scale of 1: 100. Here, too, there is a cost calculation according to DIN 276 and the results are recorded again in the form of a result display.

Approval planning

During the approval planning , the templates for the approvals and permits are created by the authorities. A submission plan is drawn up, which serves as the basis for negotiations with the authorities. This is followed by the approval of the project by the building authorities.

Implementation planning

The implementation planning is an instrument used by architects and engineers, in which implementation plans on a scale of 1:50 and detailed drawings on a scale of 1: 1 to 1:20 are created. The execution planning also includes a detailed project description for the execution.

Preparation of the award

Subsequent to the implementation planning, specifications are drawn up and comparable offers for the implementation are obtained.

Participation in the award

The offers received are checked and the offers are evaluated. A price comparison is drawn up and the order is placed.

Construction supervision

After the start of construction, the execution of the property is monitored for compliance with the planning and the specifications. The supervision of the construction phase also includes setting up and adhering to a schedule, checking measurements and invoices from the executing companies and compliance with recognized rules of technology. The services are technically checked and any deficiencies are identified and eliminated.
