Abstract

Purpose

The purpose of this paper is to identify the most influential buildings elements in term of the cost for timber restoration works.

Design/methodology/approach

The research employed the case studies methods with questionnaires surveys. Two case studies were chosen and questionnaire surveys were distributed to contractors and consultation companies. The cost was identified based on the elemental cost analysis of historic timber buildings.

Findings

The restoration of historic timber buildings in Malaysia has grown rapidly, especially in the UNESCO world heritage sites, Melaka and Penang. Data obtained on the restorations of timber buildings show that the most influential elements were upper floors, roofs and walls. Termites’ invasions and the lack of building analysis were found to be the major issue in timber restoration works. In addition, the availability of timber material contributed significantly to the increase of cost for restoration works.

Originality/value

The cost for every element was identified and was used as a reference for new restorations projects of historical, timber buildings. This paper also highlighted the causes for the problems and the factors affecting the cost of timber restoration works. These data are useful information, especially for surveyors and contractors who are involved in the restoration of historic timber buildings. Maintaining or replacing these elements with other material can help to minimise the restoration cost of timber buildings in Malaysia.

Abstract

Since the time of primitive man, timber has remained the most useful and versatile of all naturally available materials. Its obvious aesthetic value makes it irreplaceable in the manufacture of fine musical instruments, furniture and great works of sculpture, but its greatest use is in the construction of our dwellings. Whether used in its almost natural state to construct a forester's log cabin, or sliced up into convenient pieces to build most of the world's homes, it is unsurpassed for versatility, ease of working and mechanical strength.

Abstract

Purpose

Timber export is an important economic development pillar in Ghana, which has a direct effect on Ghana’s domestic forestry industry development, local communities’ income and sustainable forest management and deforestation. China, as the Ghana’s largest timber export destination, brought significant impacts on Ghana’s timber export. However, there is a lack of quantitative analyses on impact factors of timber trade between the two countries in the past, which this paper sought to do.

Design/methodology/approach

The authors first collected Ghana’s timber exports to China from 1997 to 2017, and then based on the literature review and trade theories, the authors set up a least squares estimate (LSE)-based multiple linear regression (MLR) model to analyse the specific impact factors. In addition, multi-collinearity, autocorrelation and heteroscedasticity issues of the impact factors were checked to guarantee the accuracy of the results.

Findings

The results showed China timber import volume, Ghana cedi (GHC)/US$ exchange rate, Ghana’s gross domestic product (GDP) and China timber consumption volume in construction sector had positive impacts; Ghana timber production volume and Ghana average timber export price had negative impacts. The results confirmed that China’s timber consumption had a positive linkage with Ghana’s timber export. The article also reviewed possible impacts caused by change in timber trade policies, which proved important but was hardly directly quantified. The authors pointed out the importance of optimizing these impact factors to make sure Ghana’s timber export to China went on the sustainable track.

Originality/value

There is no literature about timber trade and its impact factors between Ghana and China, which used econometric models. This paper provided new perspectives on the impact factors in timber trade between the two countries.

Abstract

The authors construct an intertemporal model of rent-maximizing behavior on the part of a timber harvester under potentially multidimensional risk as well as geographical heterogeneity. Subsequently, the authors use recursive methods (specifically, the method of stochastic dynamic programing) to characterize the optimal policy function – the rent-maximizing timber-harvesting profile. One noteworthy feature of their application to forestry in the province of British Columbia, Canada is the unique and detailed information the authors have organized in the form of a dynamic geographic information system to account for site-specific cost heterogeneity in harvesting and transportation, as well as uneven-aged stand dynamics in timber growth and yield across space and time in the presence of stochastic lumber prices. Their framework is a powerful tool with which to conduct policy analysis at scale.

Abstract

Purpose

This paper examines the relationship between traditional timber frame structure and the diasporic identity of the Southern Fujianese Chinese community in West Malaysia. It analyses the cultural semiotics of Southern Fujianese traditional Chinese temple timber frame structure architectural language. This study addresses the under-examined domain of Chinese cultural identity representation through the architecture of traditional Chinese temples in Malaysia. It seeks to understand its underlying structure and process involved in revealing its disposition within the cultural phenomena from the perspective of Chinese cultural semiotics.

Design/methodology/approach

Selected Southern Fujianese traditional Chinese temples in West Malaysia built between the 18th to the 19th century that retain the traditional timber frame structure were investigated through field survey and focused publication review. Historical interpretive analysis and typological analysis supplement the cultural semiotics analysis to assess the timber frame structure attributes concerning architectural language expressions.

Findings

Findings reveal that the architectural language signifiers of the structural disposition of the timber framework and its corresponding formal articulation establish a clear statement of the Southern Fujian Chinese cultural identity.

Originality/value

The evaluation of the cultural identity signifiers helps to understand the underlying structure and process of the Chinese cultural semiotics in architecture. Results of this research substantiate the significance of timber frame structure in preserving the architectural heritage of the Southern Fujianese traditional Chinese temples. They provide important references for conservation and cultural studies of such building typology.

Abstract

Purpose

This study examined data from 13 international tall residential timber building case studies to increase our understanding of the emerging global trends.

Design/methodology/approach

Data were collected through literature surveys and case studies to examine the architectural, structural and constructional points of view to contribute to knowledge about the increasing high-rise timber constructions globally.

Findings

The main findings of this study indicated that: (1) central cores were the most preferred type 10 of core arrangements; (2) frequent use of prismatic forms with rectilinear plans and regular extrusions were identified; (3) the floor-to-floor heights range between 2.81 and 3.30 m with an average of 3 m; (4) the dominance of massive timber use over hybrid construction was observed; (5) the most used structural system was the shear wall system; (6) generally, fire resistance in primary and secondary structural elements exceeded the minimum values specified in the building codes; (7) the reference sound insulation values used for airborne and impact sounds had an average of 50 and 56 dB, respectively.

Originality/value

There is no study in the literature that comprehensively examines the main architectural and structural design considerations of contemporary tall residential timber buildings.

Abstract

Purpose

The purpose of this paper is to improve the understanding of the impact of mass timber construction methods on construction performance through the successful delivery of the first-of-a-kind tall wood building, Brock Commons Tallwood House (Tallwood House). This paper is one of a set of papers examining the project; companion papers describe innovations used during the mass timber design and construction processes.

Design/methodology/approach

A mixed-method, longitudinal case study approach was used in this research project to investigate and document the Tallwood House project. Quantitative data were collected to perform the following analysis: hook time, the variability of productivity and schedule reliability. Members of the research team observed construction progress, meetings and decision-making, conducted periodic interviews and reviewed project artifacts.

Findings

The research presented in this paper is the culmination of a longitudinal study aimed at studying the innovation process on a project where radical innovations of structural systems were developed. Prefabrication, combined with the use of a virtual design and construction (VDC) model for planning and fabrication and early collaboration with trades, construction managers and consultants, increased the labor productivity of the on-site erection of the mass timber structural components and envelope panels and expedited the construction schedule.

Originality/value

This paper details an in-depth investigation into the construction productivity for a unique building project and lessons learned. The case study chosen is the construction of Tallwood House at the University of British Columbia. Tallwood House was the tallest mass-timber hybrid building in the world at the time of its construction.

Abstract

Purpose

The purpose of this paper is to study the possibility of promoting certified timber coming from sustainable managed forests, in order to support Greek enterprises and the institutions of the Greek timber sector involved to apply effective green marketing methods and policies.

Design/methodology/approach

Based on a prototype questionnaire, specifically structured for the aim of the research, 55 responses were collected from Greek timber enterprises in April 2009. The questionnaires were processed and analyzed with the statistical program SPSS of ver17.0, using descriptive statistics and correlation analysis. The main purpose was the investigation of knowledge, use and promotion of certified timber that emanates from forests under sustainable management, thus planning the green marketing.

Findings

The Greek enterprises of the timber sector expressed a great interest in the protection of forests all over the world, ranging from illegal loggings to their rational management. At the same time, in their overwhelming majority, they strongly support the certification of the sustainable management of Greek forests. These enterprises believe that the movement of green buildings has also reached Greece, albeit at a slow pace, and forecast that green consumers are prone to offer an additional percentage of about 6 per cent on price, in order to buy certified timber products. Companies trust to a high degree most institutions of higher education (universities and technological institutions) for the promotion of certified timber products and propose their publicity through newspapers and magazines, as well as through internet portals of close contact. Finally, the paper discusses reflections and forecasts on the growth of this new market of timber.

Practical implications

The results offer precious knowledge on the market of certified timber and its future developments in the following five years, which can assist both enterprises and the institutions involved in strategy forming and decision making, in order to gain an important share of the market of green consumers. The paper also proposes effective green marketing applications.

Originality/value

This is the first research on green marketing and the promotion of certified products of timber in the Greek market, while similar work is very limited even at an international level.

Abstract

Purpose

The purpose of this paper is to explore the alternative procurement procedures that will address the complexity of issues surrounding timber procurement for housing reconstruction after the Tsunami in Banda Aceh. It reviews construction supply chain management (SCM) and procurement philosophies with a project management (PM) perspective to facilitate the logistics of post‐disaster reconstruction.

Design/methodology/approach

Based on two fieldtrip experiences in Banda Aceh in 2006 (one month) and 2008 (two months) with the housing reconstruction program of an international non‐governmental organisation, this paper examines the modern literature on SCM and analyses this process associated with construction material procurement in practice, reviews the problems inherited in the Indonesian context and analyses the proposed procedures of local and international procurement of timber to streamline the supply for reconstruction in Banda Aceh, Indonesia.

Findings

The incorporation of sustainable considerations into the design of procurement routes in the overall PM process for post‐disaster construction should be well recognized. The paper shows that basic SCM philosophies of ensuring stakeholder integration and collaboration could reduce the problems in timber procurement in Banda Aceh. Sustainable construction and triple bottom lines criteria are proposed to ensure a value creation process for a wider stakeholder engagement and overall reconstruction project delivery.

Originality/value

The paper provides useful PM insights into SCM and sustainable construction literature. The case study reviews the timber procurement problems and goes further to present two alternative procurement models that could be implemented as more sustainable responses to post‐disaster reconstruction in Banda Aceh.
