Design for Manufacture and Assembly (DfMA) in Industrialized Construction: A Pathway to Advanced Construction Methods
Mohsen Vafamehr, Nastaran Esmaeili,
Volume 35, Issue 2 (4-2025)
Abstract
With the resurgence of building industrialization, the phrase DfMA has gained popularity, representing a new approach to future construction. Applying the DfMA principles would promote a design process that optimizes manufacturing and assembly functions, leading to cost and time savings. Such a process could significantly impact product quality and improve the construction industry's performance with a suitable strategy and guidelines. Analyzing DfMA uptake in the construction industry is crucial to understanding its current and future implementation. However, more studies are still needed on this topic. This review primarily aims to identify the factors of DfMA for advanced industrialized construction.

Applying the DfMA principles would promote a design process that optimizes manufacturing and assembly functions, leading to cost and time savings. Such a process could significantly impact product quality and improve the construction industry's performance with a suitable strategy and guidelines. Analyzing DfMA uptake in the construction industry is crucial to understanding its current and future implementation. However, more studies are still needed on this topic. This review primarily aims to identify the factors of DfMA for advanced industrialized construction. This research aims to integrate DfMA principles into industrialized construction by leveraging advanced construction components and their connection with DfMA. This study used a multi-step research method to achieve the main research goal: creating an analytical framework for advanced industrialized construction through bibliometric analysis and using qualitative meta-analysis to identify DfMA factors and general DfMA-like concepts in advanced industrialized construction. We arrived at a conceptual model by identifying factors and elements of the DfMA for industrialized construction. Implementing automation and robotic systems into the construction process, off-site construction, construction 4.0, information communication technology and digital technologies, prefabrication, lean construction, sustainability, and virtual design and construction are DfMA factors for advanced industrialized construction. This document provides a reference for future construction direction to achieve advanced industrialized construction and can be used as a starting point for more theoretical and empirical research.

The Critical Review of Urban Planning's Disciplinary and Professional Status in Iran
Saeed Nemati Pour, Mahmoud Ghalehnoee, Mahin Nastaran,
Volume 35, Issue 2 (4-2025)
Abstract
This paper presents a critical examination of the status of urban planning as a discipline and profession. The paper is comprised of two main sections. The first is a theoretical review of various selective related studies conducted in English-speaking countries, with a particular focus on those from the United Kingdom and the United States. The second is a survey of 61 professional and graduate urban planners in Iran, which was conducted using a non-probability sampling method. The most significant variables examined are the essential skills and competencies of planners, the inclination to pursue the same field of study once more, and the discrepancy between academic education and professional training. In conclusion, the theoretical and survey-based findings are interpreted from sociological, epistemological, and political economy perspectives, and recommendations are provided. This article is distinctive in its use of an interpretive approach to quantitative and qualitative findings, as well as its combination of quantitative and qualitative methods to achieve a form of causality in the issues of the field and profession of planning.
