This R&D program has the aim to reduce the risk of damage caused by groundwork (excavation, foundation and construction work) during and after execution of a project, and the risk of damage to neighbouring structures. The project has 18 partners representing all stakeholders within the building and construction sector. The Research Council of Norway (RCN) is supporting the work through the programme for "User-driven Research Based Innovation (BIA)". The RCN support is crucial for this sector-wide cooperation and for the realization of the project.
The primary objective of BegrensSkade II / REMEDY is to integrate foundation engineering and risk assessment and management, in order to reduce the technological and economic risks of damage caused by groundwork. To achieve this objective, geo-research is needed on the causes of excessive settlements and other damage triggers, and new guidelines and requirements for design and construction are urgently required.
The research will lead to more efficient and more reliable design and construction. BegrensSkade II / REMEDY has the potential to realize cost savings of billions of NOK annually in the building, construction and property sectors in Norway. BegrensSkade II / REMEDY is a further development of the previous BegrensSkade R&D program. See more information about the project background.
The project has 18 partners representing all stakeholders within the building and construction sector: contractors, consultants, suppliers, property and project owners, public organizations and insurance companies, as well as research organisations. Each industry partner will contribute a total cash funding of 300 kNOK over five years.
BegrensSkade II / REMEDY will focus on the three most common causes of damage (documented in BegrensSkade) and two additional source of uncertainty and potential significant damage:
- Drilling for foundation piles and supporting tie-back anchors for sheet pile walls, causing erosion, disturbance and drainage which in turn causes reconsolidation.
- Drainage towards excavations causing pore pressure lowering and settlements of soft clay.
- Lack of assessment of the risk involved in different solutions.
- Methods for deep excavations where there is an increasing need for unconventional (new) methods for larger and deeper excavations than earlier.
- Vibrations after-effects of construction activity, e.g. rock blasting, hammering, compaction or pile driving.
Each of these situations are encountered in building and construction projects presently underway in Norway.
Six work packages (WP)
Research tasks in BegrensSkade II / REMEDY comprises six work packages (WP1 to WP6):
WP 1: Drilling for installation of piles and tie‐back anchors
WP 2: Deep excavations and foundations
WP 3: Hydrogeological methods, drainage and grouting
WP 4: Vibrations induced by construction activity
WP 5: Risk assessment and management
WP 6: Cooperation, guidelines and competence build‐up across entire sector.
Key Deliverables: Improved methods and guidelines
BegrensSkade II / REMEDY will reduce the risks due to damages caused by groundwork by integrating new geotechnical engineering solutions with risk assessment and management, and improving the interaction and cooperation among the stakeholders in the building construction and property sectors. Improved methods and guidelines will be developed for:
- drilling for anchors and piles,
- deep excavations and foundations,
- effect of drainage and grouting methods, and
- damage from vibrations due to construction activity.
