Construction management

from Wikipedia, the free encyclopedia

The construction management (short BL ) manages a construction site or parts of a construction site. She is responsible for the proper execution of the construction work. The term is used both for the construction management of the client (client) and for the construction management of the contractor (construction company).

Definition of terms

In sheet 1 of VDI 4700, the site manager is described as, quotation: "Supervisor of the proper construction work in accordance with the approved building plans and also compliance with the accident prevention regulations [based on MBO § 57 and WbB]". The appointment of a site manager in terms of building regulations serves to enforce public protection goals.

In road construction and civil engineering, the term construction management is mainly used for the construction management of the executing company. The site management on the part of the client is referred to here as site management and / or local site supervision because of Sections 55 and 57 of the HOAI.

Site management and site manager for each trade are deployed by the client, usually the client . As the “administrator of the client”, they primarily take on the monitoring and review of the service to be provided ( target construction ), coordinate the trades and other parties involved (possibly planners, authorities etc.) and are in direct contact with the client to clarify technical questions. The site managers continue to represent the client on the construction site and, in this function, should represent the client's interests towards the executing company. The construction management or construction management of the construction company ensures the coordination of the provision of services (personnel deployment, material deliveries, etc.) and is the contact person for the client or the client's construction management. Construction management includes the client's activities on the construction site. In contrast to this, the construction management includes the work of the foreman, i. H. the management task of the executing construction company.

Property surveillance

The fee schedule for architects and engineers (HOAI, in the version from 2013) only mentions the terms "site supervision (construction supervision)", "local construction supervision" and "site management" for the services during construction. The term "construction manager" is mentioned only once in the HOAI in Annex 10 when describing a special service, i.e. a service that is not covered by the HOAI, in the service profile buildings and interiors.

In Part 1 of VDI 4700, property monitoring is defined as the eighth service phase of the HOAI's buildings and interiors . As a note it says here, quote: "In this phase, the construction of the property is monitored for compliance with the building permit or approval, the implementation plans and the performance specifications as well as with the generally recognized rules of technology and the relevant regulations. The construction management manages a construction site or parts of a construction site. It is responsible for the proper execution of the construction work. [based on HOAI] "

Thus, the activities of a site manager overlap with the scope of services of the planner who is commissioned to monitor the property according to HOAI. However, in contrast to the construction management described in the LBO, the HOAI does not name any qualifications necessary for property monitoring and also includes significantly more activities than the coordination function in the form of managing the construction site. A contractor who, in addition to the planning, also has the construction work in the order, such as a general contractor, cannot undertake property monitoring in the sense of service phase 8 of the HOAI. The construction management with an obligation to the building authority can, however, be provided by both the planner and the executing company.

Construction management (Switzerland)

According to SIA 118 (General Conditions for Construction Work) Art. 3 Paragraph 3, the construction management is the representative of the client. Construction management can also be done by the client himself. The construction management can consist of one or more persons designated by the client (Art. 33 Para. 1). The power of attorney of the construction management is to be specified in a contract between the building owner and the construction management. In the absence of the regulation, an unrestricted power of attorney applies to the construction management vis-à-vis the entrepreneur (executing company, such as builder) in matters relating to the work to be created (Art. 33 Para. 2). According to this, the decisions of the construction management as well as the acceptance of the will of the companies are legally binding for the client.

Artistic site management

The artistic construction management supervises the execution of the design and compliance with the draft.

Public law construction manager

The tasks and qualifications of the site manager with an obligation to the building authority are defined in the 16 state building codes. In § 56 of the MBO , which has been taken over literally by many countries for this part, it says quote:

  1. "The construction manager has to ensure that the construction work is carried out in accordance with the public law requirements and to issue the necessary instructions. As part of this task, he has to ensure the safe constructional operation of the construction site, in particular the safe interlocking of the work of the contractors The responsibility of the entrepreneur remains unaffected.
  2. The site manager must have the expertise and experience required for his task. If he does not have the necessary expertise in individual sub-areas, suitable specialist site managers must be consulted. In this respect, they take the place of the site manager. The construction manager has to coordinate the activity of the construction manager and his activity. "

The granting of the right to issue instructions reflects the public interest in the protective functions of the building regulations. Therefore, the construction manager is appointed with the notice of the start of construction in the sense of building regulations. It is a function under public law that can only be assumed by declaring it to the building authority. The right to issue instructions can therefore also be directed against the builder if he violates public obligations. In the case of a strict interpretation of his tasks, the construction manager must call in the lower building supervisory authority in an emergency if his instructions are not followed. An exemption from liability by the builder, which is customary in contract law, is excluded in the sense of building regulations. While the responsible construction manager of an executing construction company is responsible for ensuring the occupational safety of his employees, the public-law task aims at the interaction of all trades.

Often the site managers of the shell construction company are appointed in accordance with building regulations. At this moment his responsibility extends to the other trades as well. Typically, a company's construction manager is an employee and is therefore subject to the employer's right to issue instructions. There is no legal regulation to avoid the contrary constellation. In contrast to the safety and health protection coordinator (SiGeKo), the transfer of the right to issue instructions appears as a criterion for hierarchical classification. There is no provision for dividing the right to issue instructions.

Construction management on the side of the contractor

Construction management or site management

The construction management of the contracting company ensures that the work is carried out on time, in accordance with the quality and economically. In addition, safety and health protection as well as environmental protection must be ensured. The site manager represents the company owner and is therefore usually responsible for fulfilling the legal , official and employer's liability insurance association obligations.

The site manager is not constantly present on all small construction sites. The permanent representation is then a foreman or polishing or foremen . On large construction sites, the construction management is organized hierarchically:

  • Senior Site Manager
  • construction manager
  • Section supervisor



In Germany, the fees set in the HOAI are binding price law for the remuneration of property supervision and local construction supervision in the client's order as a work contract. Since the decision of the ECJ on July 4, 2019, which states that the maximum and minimum rates in the fee schedule for architects and engineers (HOAI) violate the EU Services Directive passed in 2006 and the freedom of establishment in the member states of the EU, the minimum - and maximum rates of the HOAI are no longer mandatory, instead the fees are to be freely agreed in the future. In the service profile for buildings and interiors, Annex 10 , a special service, quote: "Activity as a responsible site manager, insofar as this activity goes beyond the basic services of LPH 8 according to the respective state law". Special services are services that are not recorded by the HOAI. Thus, all services that go beyond the HOAI are to be paid for by means of a separate agreement between the client and the customer.

The appointment as site manager in terms of building regulations does not result in any claim for remuneration. If construction management is transferred in accordance with civil law, there is only an additional claim for remuneration in special exceptional cases if construction management is transferred at the same time in accordance with the building regulations. Such a constellation can arise in the state of Brandenburg. A property planner must be appointed there, who takes over the construction management in terms of building regulations himself or has it carried out under his responsibility. After the construction work has been completed, a declaration of completion must be submitted stating that the project was built in accordance with the approved documents.
