Construction Schedule and Delay
BRG’s construction delay professionals specialize in applying complex forensic delay analysis methodologies.
Schedule Delay Claims and Expert Analysis
Construction delay claims are one of the most misunderstood disputes in the construction industry. Due to advancements in technology and the additions of complex business relationships, construction scheduling has become an integral part of every major project. Our global scheduling experts have advanced knowledge of CPM schedule analysis and extensive experience solving delay, disruption, and acceleration issues.
BRG’s delay experts have authored numerous publications in the field of schedule delay analysis and sit on international committees for the development of schedule analysis protocols, including AACE International, the American Society of Civil Engineers (ASCE), and the Society of Construction Law (SCL).
Our team has a solid understanding of and extensive expertise in delay analysis methodologies across various international protocols. Our experts have worked on a range of complex projects around the world and have provided expert reports and testimony in a variety of international arbitration tribunals, including the: SIAC, ICC, ICSID, DIAC, IAC, and KCAB.
BRG’s delay experts ascertain methodology selection based on the circumstances of the dispute, documentation available, and contractual requirements. Analysis methodologies implemented have included:
- Time impact analysis
- As-planned versus as-built
- Time slice/windows analysis
- Half-step analysis
- Collapsed as-built
BRG experts help clients understand which methodology is best suited to their requirements.
4D Scheduling
Our Global Construction practice offers clients 4D scheduling services, which take a three-dimensional model of a construction project and essentially adds a fourth dimension: time. A 4D schedule leverages additional value from a project’s 3D/Building Information Model (BIM) and critical path method (CPM) schedule by combining the two documents to create a powerful visualization and planning tool. BRG uses cutting-edge 4D scheduling software that links the BIM elements (such as columns, slabs, doors, and windows) to the appropriate CPM schedule activity. By linking the BIM elements and CPM schedule activities, BRG produces an animation of project construction over time as planned in the CPM schedule.
The cost to prepare a 4D schedule is nominal and represents a small fraction of the cost in preparing a project model. The added value supplied by a 4D schedule in international arbitration hearings is that the 4D model provides an effective way of graphically portraying the factors that caused delays and disruption on complex projects and schedules with thousands of activities that otherwise would be difficult to demonstrate using Gantt charts alone.
