Abstract

In building projects customer requirements, constructive aspects and quality standards are defined during the design phase. However, this important phase is usually carried out with little interaction between the construction and design teams causing many problems during construction such us: incomplete designs, change orders, rework, construction delays, etc.

The most frequent problem was the continuous change and modifications of the design. The analysis of the information collected showed that the current design process is incomplete and chaotic and it does not allow the construction professionals a complete exposure to the completed design and it prevents the interaction among the different specialties that intervene in the process.

DESIGN QUALITY CONCEPT TO IMPROVE BUILDING QUALITY Designing for building quality
Silvio Melhado

Despite the fact that there is a common sense in several published research about the importance of the design's contribution to quality improvement, the design concept itself has not been properly analyzed by many authors. Almost all these works present many factors related only to the building characteristics as a product, not as a complex process. This work discusses the potential contribution of design to quality and how it could be more effective, or rather how building design procedure must be organized and considered as a part of the project plan to achieve the best quality results. For this purpose, a casestudy is presented as a referential portrait. The clients satisfaction factors, involving mainly the needs of customers, construction companies and investors, are analyzed under a contemporary and systematic point of view. On the basis of this analysis, a proposal of guidelines will be briefly described in order to approximate the production and the design objectives, which will consequently change the design team arrangement and the design coordination and control methods.

Linking quality management, teamwork and integration to define a new model of design management for building construction
Silvio Burattino Melhado

Over the last years, in Brazil, no matter if pushed on by competitiveness or searching for certification, contractors have worked very hard on process standardisation and quality systems implementation. As a result, the request for design management has grown and architects and design engineers have been encouraged to change organisational models aiming to accomplish such new and large market requirements. This scenery allowed a new outlook into client-designer relationship, thus renewing the most usually adopted concepts and practices of the sector.

Quality issues related to the design and construction stage of a project in the Indian construction industry
sharmin khan

Frontiers in Engineering and Built Environment, 2021

PurposeQuality in the construction industry is an important issue yet ignored during the initial stages of the life cycle of a project, that is, the design and construction stage. The contribution of stakeholders, especially the architects is generally suspended though it has huge significance in terms of cost and time related to quality. This research endeavors to examine the issues related to the design and construction stages of the project from architects' purview, to understand the relative importance of these issues in the Indian construction industry.Design/methodology/approachThe study of qualitative data conducted formed a basis for online quantitative data collection that was further analyzed with the help of cross-tabulation and multiple correspondence analysis methods.FindingsThe study concludes that the budget of a project is a corresponding factor related to quality concern for architects. The study also established that the quality issues corresponding to high bud...

Analysis of Owner’s Design and Construction Quality Management Approaches in Design/Build Projects
kevin lai

This paper explores and classifies current approaches to evaluating quality in design/build (DB) proposals. It does so by a thorough content analysis of 78 requests for proposal (RFPs) for public DB projects with an aggregate contract value of over $3.0 billion advertised between 1997 and 2002. In most DB projects, the owner requires the DB contractor to establish a firm-fixed price on a project that has not yet been designed. Usually, the owner also fixes the project delivery period. In the traditional design/bid/build (DBB) system, quality is fixed through the plans and specifications. Thus, in DBB, with schedule and quality fixed, the cost of construction is the factor in which the owner seeks competition. Conversely, in DB, with cost and schedule fixed, the scope and hence the level of quality is the main element of competition. This paper identifies the six owner approaches to articulating DB quality specified program, performance criteria, specification, and warranty. These are important for DB contractors to understand so that they can craft their proposal in a manner that is both responsive to the owners’ requirements and consistent with the owner’s system to make the best value contract award decision.

DESIGN AND DOCUMENTATION QUALITY AND ITS IMPACT ON THE CONSTRUCTION PROCESS
Paul Tilley, Stephen McFallan

The quality of design and documentation has a major influence on the overall performance and efficiency of construction projects. As designers provide the graphic and written representations which allow contractors and subcontractors to transform concepts and ideas into physical reality, it is the efficiency with which this transformation occurs that determines the level of project performance and efficiency achieved.

Design Management in a Construction Company
Michael Nycyk

"Design Management is an increasingly important function in the construction industry. Design management is being done by construction companies because of the failure of other existing systems to achieve proper integration of the design and construction processes. Initial results from a three-year empirical study of the practice of design management in an international construction company have been compared to conceptions devised from literature in order to describe the design management practices. This is being done in order to provide a foundation, which can be used to generate better co-ordinated design and construction in complex one-off engineering projects. Three conceptions of design management: design management as “integrators of design and construction”; design management as “managers”; and design management as “meta designers” were devised from literature and compared to several case studies conducted on a variety of projects. Early results indicate that during the operational stages of a project design management in the company can be better conceived as “meta designers” rather than as “managers”. The design management personnel were responsible for designing a system, which made stakeholders the co-developers or co-designers; they did tasks that designers are responsible for in smaller projects, but which inevitably get lost in larger projects; and they dealt with issues arising from the integration of design and construction."

The Importance of the Design for Production in the Design Process Management in Building Construction
Silvio Melhado

2002

The design model, hitherto adopted by building companies, is sequential, lacks coordination and, most of the time is disengaged from the production process. It is now undergoing reformulation because of the intense concern with quality in this sector. Building companies are beginning to admit the importance of the production chain, with design acting as an element which preempts problems on the building site. The design process management assumes large importance in lean construction: adopting constructability principles; minimizing waste and reducing time. In this field of action, the design for production has been put to use by building companies to improve the production process, since it holds the necessary elements. Inserted in the design process, it seeks to support continuous improvement on building sites. The present work intends to evaluate the importance of the design for production in the design process management, checking its validation while being a support element to ...

A conceptual framework of the interface between the design and construction processes
Alan Coday

Engineering, Construction and Architectural Management, 2011

PurposeAs the construction industry strives for closer integration of the participants, more responsibility for the management of the detailed design process is being directed to main contractors and combined with their existing duties of managing the construction and pre‐construction processes. Crucially, this necessitates successful management of the interface between these processes, and this paper seeks to investigate a conceptual view of that interface to provide a foundation for improving understanding of it.Design/methodology/approachRecent and current literature is examined, and various theoretical backgrounds for the design and the construction processes are reviewed. The consequences for the understanding of the interface are discussed. The significance of conceptual frameworks is also reviewed.FindingsA significant difference is identified in the published work between the theoretical understandings of the construction and design processes. From this a conceptual framewor...

Managing the Design Process in the Construction Industry: A Literature Review
Joseph Buertey

Architecture research, 2015

Construction has existed since human existence. From the building of huts for shelter in the old ages to the construction of mega structures in recent times, the industry has developed over the years and has grown to become an enviable industry. It has transformed from a single person being the designer, builder and manager to a project environment where multiple organisations and professionals play a part. However this has not solved all the problems in the industry. One of the major concerns of the industry is the management of the design process. It is evident that unlike the olden days where buildings were built with the "trial and error" style of design as the construction went on, today's industry engages designs before construction. The findings in this review have been based solely secondary data, with extensive review of literature that was available on the subject. The review is to generate more interest in this field since there is still more to be unfolded. This research reviewed some models of the design process, industry practice on design management and the role of project management in today's industry. It however does not conclude on which of the models best suits the industry but suggests that the design process should not be managed with the same rigid tools and techniques of project management. It was concluded that the definition for design was contextual but shared certain key characteristics. The definitive part of the construction process needs a coherent management and coordination process for all stakeholders to enable the achievement if the key performance indicators of the project.

Critical Factors in Process Quality of Engineering Construction Projects during Building Design Phase
Tawiah Quartey-Papafio

International Journal of Grey Systems

Quality in construction is an important topic in the design phase due to the quick change in technological advancement. The current study focuses on the identification, measurement, and analysis of the critical elements which impact the process quality of building construction projects during the design stage in Pakistan. Elements were graded using the conservative Relative Importance Index (RII) and Grey Absolute Decision Analysis (GADA). The findings indicate that during the design phase, the critical element impacting process quality is the quality of codes and standards and was facilitated using a questionnaire survey. Similarly, the teamwork of parties in design firms and constructability analysis of the design are key factors during the design phase in Pakistan. Measures for the improvement of process quality in Pakistan were suggested. The building construction projects need to be modified to cover the important aspects of constructability analysis, continuous working on trai...

The lack of design quality focus in construction: a case for examining suitable design processes
David Greenwood

2009

A large number of projects in UK construction now involve contractor-led design and are thus very different from the traditional approach which formed the basis of the original Royal Institute of British Architects (RIBA) Outline Plan of Work. Such integrated and contractor-led approaches support the "reform agenda" of the late 1990s that was introduced to tackle process inefficiency. However, within the design professions there has been concern that this resulted in buildings that were "designeddown" to a cost rather than "designed-up" to a value. An attempt to address this resulted in the formation of the Commission for Architecture and Built Environment (CABE) in 1999 and the launch, in 2003, of the Design Quality Indicator (DQI) which measures how well a building satisfies stakeholders. This paper presents the early phases of doctoral research which will examine the impact of integrated design management approaches upon Design Quality.

Design and Design Management in Building Projects: A Review
Rıfat Akbıyıklı

Engineering Sciences, 2012

Design is that activity, largely executed by consultants and in-house disciplines, which translates the aspirations of the Client, into a series of documents, both drawn and written, which in combination can be used to procure the manufacture, assembly, commissioning and operation of both building elements and the project as a whole. Management of the design process is planned to ensure that the project requirements have been correctly interpreted in an agreed brief, with a consistent format of technical verification reports and design analysis audit trail, as set out in the project plan. This paper, based on a literature review, examines traditional design management and design and construction as an integrated system. The paper is an introductory part of an ongoing project to map design and design management practices in architectural and civil engineering practices.

Improving Design Quality by Contractor Involvement: An Empirical Study on Effects
Petri Uusitalo

Buildings

It is generally acknowledged that good-quality design is a prerequisite for good quality and productive construction work. One proposed measure to improve the quality of construction has been contractors’ involvement in the design phase, and this phenomenon has been studied by several researchers. However, such approaches have not adequately addressed how this involvement affects the quality of the design. In this study, the aim was to study the effects of the early involvement of contactors on design quality based on evaluating the design quality factors. A case study was used to collect data and content analysis to analyze structural drawings and design meeting minutes of a large-scale infrastructure project. Particularly, the focus was on gathering information on the quality of the design and how it was addressed in the design coordination. We combined this quantitative data with qualitative open-ended thematic interviews, including respondents who led and coordinated the design ...
