Development of Delay Factor Model for Substructure Works in Building Construction

Abstract

Building construction is one of the most complex construction hence construction delay is always happened. Substructure work is the first stage of building construction work. If a delay occurs in the substructure work stage, it will cause a snowball effect which can cause all of the building construction stage to be delayed. Therefore, research on the delay factor in substructure work is urgent to be mitigated at the beginning of the construction process. Identifying the delay factor is the main objective of this research. Furthermore, this research also tries to develop a model of delay factor in the substructure work stage. This research was conducted on high-risk building construction work, mix used area, and integrated with a railway station. The survey was conducted on 30 professional engineers in building constructions. This research was started in identifying the delay factor and analyzed using multiple regression methods to determine the influence of delay factors. The analysis showed that 13 delay factors that have a significant influence on project delay with a value of p<0,050. The three highest correlated delay factors are government policy factor (r=0,880), construction work accident factor (r=0,847), and design factor (r=0,843). The identified delay factors can be intervened by mitigating that at the beginning of the project in order the future projects not to be late.

Relationship between Job Satisfaction and Employee Performance in the Construction Industry of Pakistan

“…Regression analysis enables us to predict future outcomes based on the predictor variables. Kurniawan [51] used multiple regression in developing a delay factor model for substructure works in building construction. The type of relationship between the initial and actual or final contract duration in South Africa was determined using regression analysis [52].…”

Analisis Pengukuran Relative Importance Index (Rii) Untuk Menentukan Peringkat Faktor Penyebab Keterlambatan Pekerjaan Kanopi Proyek East Connection Taxiway Bandara Soekarno-Hatta

“…Hasil analisis Relative Important Index (RII) menunjukkan bahwa variabel Kondisi Keuangan (X5) dengan nilai RII sebesar 0.864 merupakan peringkat pertama. Kondisi keuangan atau finansial merupakan faktor yang sangat mempengaruhi keterlambatan pelaksanaan proyek [6,7].…”

“…Variabel Material (X2) dengan nilai RII 0.824 merupakan peringkat kedua. Ini merupakan faktor yang sangat mempengaruhi keterlambatan [6,7]. Hal ini sangat dipengaruhi kekurangan material, perubahan spesifikasi dan kualitas material, kerusakan material, serta pengiriman yang terlambat [9,15,17,18,25].…”

“…Beberapa penelitian tentang faktor penyebab keterlambatan proyek telah dilakukan di Indonesia. Faktor penyebab keterlambatan proyek antara lain sumber daya manusia, material, alat, karakteristik lokasi, finansial, kondisi fisik bangunan, desain, kebijakan pemerintah, cuaca, hal yang tidak diharapkan, dan kecelakaan kerja [5,6]. Hal serupa juga dihasilkan oleh penelitian lain yaitu penyebab keterlambatan proyek di Aceh disebabkan material, alat, finansial, lingkungan, pekerja, implementasi, manajemen, politik, kriminal dan manajer proyek [7,8].…”
