Abstract

Building construction on soft soils including on peat has many challenges and difficulties. The failed and deteriorated buildings have a big impact on the community. The IConCEES International Workshop 2015 which was conducted on October 2015 convened as a joint venture between Universiti Tun Hussein Onn Malaysia (UTHM) and the University College of Technology Sarawak (UCTS). The aim was to invite regional experts from academia and the industry to formally present and discuss the various construction problems encountered when working with peat. The discussions were divided into two divisions; infrastructure and building construction. This paper discusses the outcomes of the workshop and focuses on the factors and relevant challenges when constructing buildings on peat. The experts have discussed regulatory and construction issues including: drainage issues, site investigation practices, monitoring and construction guidelines. A few suggestions were outlined as a remedy to these problems and to better assist the peat practitioner at work.

Summary

Introduction

Peat is that separated soil material consisting mainly of plant remains in various degrees of decomposition; fibric, sapric and hemic. Building on peat entails a huge amount of uncertainty, as all textbook bearing capacity, consolidation and shear strength theories are based on inorganic soils. Peatland is widely scattered all over Southeast Asia and Malaysia. Knowing this it becomes vital for construction engineers to study the impact of construction on peat in its various forms of decomposition. While this paper is devoted to the discussion on the superstructure/building presentations and session, another will present the results and discussion on the infrastructure session. The superstructure/building session was further subdivided into two parts, the presentations and the plenary session
