Glossary

BIM (Building Information Modeling)
A digital method for the design, construction and management of infrastructure. It involves creating a 3D model containing all relevant information (e.g. building components, materials, costs, maintenance data), which is shared by all project stakeholders.

IPA (Integrated Project Management)
A collaborative project model in the construction industry in which the client, designers and contractors work together at an early stage and share common goals, risks and benefits. The aim is to achieve more efficient planning, better quality and lower costs through collaborative partnership. The aim is to achieve more efficient planning, better quality and lower costs through collaborative partnership.

LCM (Lean Construction Management)
A management approach in the construction industry based on the principles of lean management. The aim is to reduce waste, optimise processes and make workflows more efficient in order to deliver construction projects faster, more cost-effectively and to a higher standard.

BIM2AVA
A digital interface or method whereby data from a BIM model is automatically used for AVA processes (tendering, contract award and final accounts). Quantities and component information are extracted from the 3D model to create bills of quantities and calculate costs.

BIM-5D
An extension of BIM in which the 3D model is supplemented with information on costs and time (5D). This allows quantities, costs and budget trends to be automatically derived from the model and continuously updated during the planning and execution phases.

ITS (Intelligent Transport Systems)
Intelligent transport systems that use information and communication technologies to manage traffic more efficiently, safely and sustainably. These include, for example, traffic management systems, real-time traffic data and smart traffic lights.

roads (Roadwork Administration and Decision System)
A specialist IT system used by the City of Hamburg for the digital planning and coordination of construction works on the road network. Construction works are recorded with georeferenced data, scheduled and coordinated between various stakeholders to avoid conflicts between construction sites and reduce traffic disruption.

OKTAGON
A specialist IT system for the digital processing of building permit applications. It supports building control authorities in the management of building applications, electronic files, documents and approval processes and enables more efficient, digitalised collaboration between authorities and applicants.

BauWeiser
A central online service provided by the City of Hamburg for the planning and approval of civil engineering works. The system consolidates various specialist procedures (e.g. utility line enquiries, excavation permits or site coordination) and maps the application and approval processes for construction projects digitally and across different authorities
