Abstract
Construction of infrastructures on peat land is a very challenging task due to its properties of low shear strength, high compressibility and high water content. This paper summarizes various solutions which could be adopted for the construction of infrastructure on peat, as reviewed by the experts and panels during IConCEES International Workshop 2015. Engineers could (a) avoid peat, such as to transfer the load to the hard layers through end bearing piles or to replace the peat with the other soils, or (b) construct on peat with special precautions, such as by reducing the weight of the construction materials and dewatering the peat to improve the engineering properties. This paper serves to generate new ideas and give insights of the problems commonly encountered by the industry. Some of the proposed solutions might never be tested on peat. This would rely on the researchers to take up the challenge to further investigate and address the technical issues outlined in this paper.

Summary
Peat is brownish-black in dye which consists of decayed organic and mineral substance (Figure 1) It is a naturally occurring highly organic substance derived primarily from plant material [1]. Peat is often considered problematic for the construction due to its low shear strength, high compressibility and high water content. IConCEES International Workshop 2015 was organised on 12-13 October This workshop invited the 12 keynote and expert speakers from various countries, such as Malaysia, Thailand and Indonesia, and assembles about 47 panels from the sectors of academic, industry, governments and R&D to study the problems and propose solutions for the construction on peat. This paper reports the outcomes obtained from the workshops, focusing mainly on infrastructures
