Construction Management
Construction Management represents the final transition between the project and its realisation. In this phase, design choices are tested for constructability, subsystems, components and specific products are defined, and the documentation that trades will use directly on site is prepared. It is here that technical precision meets the operational reality of the executing contractor.
Work is carried out in close coordination with sub-contractors, integrating their construction expertise into the design process. Combining the designer’s intent with the contractor’s construction knowledge reduces misunderstandings on site and enables more effective management of construction criticalities. All documentation is developed in a BIM environment, with the model updated continuously through to as-built delivery.
Variations during construction are a natural part of any complex site; when not managed methodically, however, they become budget overruns and contractual liabilities that are difficult to recover. Variation management therefore requires a structured process, not a reactive response.
Each variation requested by the Client is analysed for technical scope, quantified for economic impact and assessed against the programme before approval. Approved variations are recorded in the Variation Register, keeping the overall Cost Forecast updated through to Final Account. The service operates in support of the Client or in coordination with Site Supervision, ensuring that every change is verified before becoming a contractual element.
