Technology Innovation

01 Wet Inter-floor Noise Reduction Construction

Through its own development of wet construction and semi-dry construction, we apply the inter-floor noise reduction construction with excellent performance to houses, and secure technology to carry out continuous research and development. In addition, Doosan E&C, as KOLAS Certified Testing Agency, is striving to improve the quality of on-site construction through the appointed interlayer noise experts.

• Accreditation of KOLAS Certified Testing Agency: Accreditation number KT531

02 Construction Site Noise Reduction System

Based on the prediction of noise generated during construction from the initial construction stage, the optimal construction method is presented and applied. In consideration of the characteristics of various construction types, we are doing our best to provide a pleasant construction environment by minimizing the occurrence of local complaints through faster on-site response.

03 SMART GREEN SYSTEM

For artificial ground greening integrated with soft FRP coating material and the inner sheat (non-woven fabric + PET film + self-adhesive butyl rubber) is a sheet-coating double composite waterproofingroot resistance method. FRP coating material is a soft type, so it can respond flexibly to external impact or structure behavior after construction, and in the construction method, both glass fiber and soft resin, which are for stiffness reinforcement of the coating material, are mechanized by an automated spray-up method, enabling safe and easy construction.

04 Predicting the Formwork Demolding Time

In carrying out concrete construction during the winter season, this is a technology that can not only move up the formwork demolding time, but also it can make the prediction of the time possible according to the environmental conditions of each site and the ready-mixed concrete proportion conditions. Doosan E&C can effectively predict and manage the formwork demolding time, after calculating the maturity index of the concrete in consideration of the hydration heat generated from hardened concrete, which is a new concept of predicting the formwork demolding time by the maturity index-based method.

05 Implementation of Concrete Unit Quantity Measurement Standard

The unit water quantity of concrete formulation is important for concrete quality control as a factor that has a great influence on not only the constructability of unhardened concrete, but also the compressive strength, shrinkage cracks and durability of hardened concrete. Recently, as the concrete unit water quantity measurement test has been applied to strengthen ready-mixed concrete quality control, preemptive activities are being carried out to secure quality control at all sites.
