TY - JOUR T1 - Delay factors in execution of design & build construction projects A1 - Agnieszka Leśniak A1 - Grzegorz Piskorz JO - Acta Sci. Pol. Architectura} VL - 17 IS - 4 SP - 17 Y1 - 2018 UR - https://www.architectura.actapol.net/volume17/issue4/_4_.pdf SN - 1644-0730 KW - delays in construction, identification of factors, construction works, design and build system AB - One of the most advantages of the design and build system of construction projects is reduction of the time required for the investment process. Choosing one contractor, and thus integrating design and construction stages, ensures better coordination and reduces problems with work implementation. Any construction project, even one that is excellently planned and organized, is prone to the risk of unforeseen events and problems, which – in effect – can cause delays in works completion. The article presents the results of research conducted among the investment process participants. One attempt was to identify and assess potential causes of delays arising at the design stage of the integrated design and build construction projects. ER -
