A new technology in construction has implemented Industrialised Building System (IBS) as an adoption of a new method. Till date, the reception of Industrialised Building System (IBS) has been effectively advancing by Construction Industry Development Board (CIDB). Several of exertions have been taken, for example tremendous of research financing, preparing, and building up standard and other showcasing plan. From previous writing and industry report, the appropriation of IBS was practiced gainful to improve the construction quality and profitability and spare expense and also the duration of completion projects. However, there are still a few issues and problems, such as supply chain and design drawing issues, which has always been one of the biggest problems that should be taken care of in the construction industry. Nowadays, Industrialised Building System (IBS) also has been modified in many ways to make it more practical to use in the construction field. The IBS usage becomes a trend and also a requirement for a government project especially in the northern region of Malaysia such as Kedah and Perlis. Hence, this paper focuses on latest review which is about the new method implements in Industrialised Building System (IBS) technology, which is known as a Hybrid System method. This system is not yet to be found since it is one of the pilot projects from the government. Thus, the survey for this paper will evaluate the outcome whether the new Hybrid System method leads to delay in Industrialised Building System (IBS) or it can help to improve the deferrals of construction.

Hybrid System method is one of the technology implements in Industrialised Building System (IBS). Methods has been acquaint in many ways in order to improve Industrialised Building System (IBS) in Malaysia. Other country such as United Kingdom also have used the term Hybrid for their concrete process known as Hybrid Concrete Construction (HCC). While in Malaysia, Hybrid System comes with a method that combines one component with two different method which are the precast component and cast-in situ method. This two combination method has called a Hybrid System method and started implements by Jabatan Kerja Raya (JKR) for mostly a government projects in Kedah state in Malaysia on 2017. Industrialised Building System has been well known as a fast completion, saving cost, and less labour needed in construction. However, the issues by using Hybrid System method has double up the time completion, splurging the cost, and enlarge the labour since it needs to cast-in situ the components, let the concrete cured and more material usage. The significance of study for this research is the new method of IBS Hybrid System is a pilot project in Kedah by JKR. Thus, this research is to control the delay involves in projects that apply IBS Hybrid System. Hence, this paper is to identify the advantages of using Hybrid System method in Industrialised Building System (IBS).
