What’s settlement monitoring of building?
Settlement monitoring of building is the monitoring of the movement and settlement of te building, foundations and roadbeds during the construction process in a scientific and systematic manner with the support of measuring equipments.
In addition, settlement monitoring of building also needs suitable measurement methods. The suitable method depends on each building, context and compatible equipment to ensure the reliability of monitoring results.
Settlement monitoring of building includes:
Some works as follows need to be monitored for settlement to assess stability, to avoid affecting the quality of the works.
- Settlement monitoring of roadbed
- Settlement monitoring of the nearby building
- Settlement monitoring of the main building
- Settlement monitoring of land during leveling process.
Unit price of settlement monitoring of building
Settlement monitoring of building depends on the number of settlement landmarks that have different unit prices. Normally, a settlement monitoring cycle has a unit price of 3 million to 15 million VND.
The unit price will decrease when the number of landmarks to monitor subsidence increases. Contact for quotation: 0903692185.
Equipments used in settlement monitoring of building
Nowadays, equipments used in settlement monitoring of building very advanced. There are many new technology devices such as: sensor, automatic…. However, the most common settlement monitoring is geometric elevation measurement using auto level with high-precision.
Usually settlement monitoring devices include:
- Leica DNA 03
- Electronic auto level Trimble DINI.
- Auto level NA2 – NAK2 – LEICA.
- And there are many other auto level devices depending on the settlement monitoring class of the building.
What is tilt monitoring of building?
Tilt monitoring is the consideration of the verticality and inclination of the building with a standard datum system. During construction, for many reasons, the structure is tilted.
It is possible that the work settles unevenly or due to the weakness of the foundation or due to external forces that lead to the tilting of the structure.
Tilting works appear in buildings of great height: antenna towers, high-rise buildings, electricity poles, wind power poles….
Equipments used in tilt monitoring of building
Equipment used in tilt monitoring and construction displacement is an electronic total station with an angular error of 1 second or 2 seconds. Besides, for tilt measurement can use high-precision laser scanner and long-range laser beam.
Horizontal displacement monitoring method with laser scanning is suitable for large-scale steel truss works such as airport terminals, bridges…
Unit price of tilt monitoring of building
The unit price of tilt monitoring depends on the scale of the number of landmarks to be monitored. In addition, the higher building’s class is, the higher unit price is.
The unit cost of tilt monitoring of building is from 5 to 15 million VND for 1 cycle
Tilt monitoring of building includes:
- Tilt monitoring of main building
- Tilt monitoring of nearby building
Displacement monitoring of building diaphragm wall
Displacement monitoring of building diaphragm wall is very important during tunneling construction. The displacement of the large diaphragm wall leads to the possibility of tilting neighboring houses or even collapse of neighboring houses. And, it is dangerous for the lives of construction workers in the basement.
Diaphragm wall displacement monitoring is often combined with groundwater level monitoring.
Methods of diaphragm wall displacement monitoring
The method of diaphragm wall displacement monitoring by total station for monitoring landmarks mounted on the wall. This method has the advantage of being easy to implement, and the cost is moderate.
Method of diaphragm wall displacement monitoring by inclinometer. This method requires modern machinery and is quite expensive.
Unit price of diaphragm wall displacement monitoring
Diaphragm wall displacement monitoring by total station costs from 5 to 20 million VND for 1 cycle. Monitoring by inclinometer depends on the number of installation materials and the depth of the probe conduit.
Normally, monitoring by inclinometer has a unit price of 15-30 million VND for 1 measurement cycle of high-rise buildings.
Settlement monitoring of roadbed and leveling ground
Settlement settlement of ground and roadbed is very necessary in the construction process.
Settlement monitoring of roadbed
In tunneling, many cases cause horizontal displacement and subsidence of the roadbed near the construction work. This displacement needs to be carefully measured to warn in time during the construction of the basement for the construction contractor.
Detection of displacements and subsidence during construction for early warning through monitoring reports. Thereby, the investor, supervision consultant and contractor can check and re-evaluate construction methods as well as design to prevent accidents, if any, during construction.
Settlement monitoring of leveling ground
Settlement monitoring of leveling ground is very necessary in the work of leveling the ground to build factory works with high-precision to ensure the compaction of the soil before construction.
In some cases, it is necessary to monitor ground settlement when implementing other geotechnical measures.
Regulations related to building deformation monitoring
Currently, settlement and tilt monitoring of building are regulated in the following documents
-
Circular 04/2019/TT-BXD dated August 16, 2019 on Amending and Supplementing Some Contents of Circular No. 26/2016/Tt-Bxd dated October 26, 2016 of the Minister of Construction regulated some contents of Quality Management and Construction Maintenance in detail.
- Circular 26/2016/TT-BXD on Detailed Regulations on Some Contents of Quality Management and Maintenance of Construction Works
- Decision No. 32/2005/QD-BXD on the Issuance of Tcxdvn 351: 2005 “Technical Process for Monitoring Horizontal Movement of Houses and Works.
- Some documents in Decision No. 3573/QD-BKHCN dated December 27, 2012 on the Publication of National Standards.
