INTRODUCTION
Infrastructure projects are often complex and involve multiple stakeholders. Moreover, due to
several inter-related designs and multi-disciplinary requirements, design management in such
projects is usually quite challenging. Normally, the clients and stakeholders as well as the
designers and constructors are scattered and disconnected, e.g. the design teams including the
lead consultant and various specialist/ sub-consultants work in different places in their respective
offices. This scattered distribution can essentially result in numerous problems such as poor
coordination, lack of collaboration, excessive variations/ design changes, abortive rework and
unwarranted delays in infrastructure developments. For example, coordinating joint design works
and project communications and information management among different design teams is often
great concern in multi-disciplinary project systems (Perry and Sanderson, 1998; Gorse and
Emmitt, 2007). Hence, dynamic interactions and continuous coordination among various
disciplines and key stakeholders are essential for achieving success in such infrastructure
projects. Although technological advances somewhat facilitate virtual collaborations e.g. through
web-based systems, personal interactions are still deemed as necessary in the construction
industry, especially non-standard practices are still prevalent. Therefore, specific best practice
initiatives adopt a system of integrated design team office arrangements to assemble multi-
disciplinary design teams and relevant client personnel, which also facilitates effective
engagement of key stakeholders and other parties.
Previous studies identified several concerns in construction project systems such as achieving
requisite design quality (e.g. McGeorge, 1988; Acharya et al. 2006; Palaneeswaran et al. 2007;
Love et al. 2008), consultancy performance (e.g. Ng and Chow, 2004) and team integration (e.g.
Baiden et al. 2006). Hence, an ongoing research aims to consolidate useful knowledgebase of
design management good practices in the construction industry. In this exercise, a hybrid
research method with triangulation approach (e.g. surveys, interviews, data-mining, literature
review and case-studies) is used. This paper presents an overview of integrated design office
1
arrangement for effective design management in large and complex infrastructure projects. Main
discussions include: (i) generic synopsis on design related procurement and management
practices in infrastructure projects, (ii) specific review of co-located collaborative engineering
arrangements for complex/ innovative designs, and (iii) some case study extracts from recent
integrated design office arrangements.
Effective design management is critical for overall success in construction projects. In general,
multi-disciplinary consultants and multiple stakeholders are involved in the design stages of
infrastructure projects. For example, a typical railway project involves several disciplines
including: civil, structural, geotechnical, tunnelling, building services, architectural works and
finishes, permanent way/ track works, overhead lines, electrical and mechanical works.
Interfaces with property development over stations and public transport interchanges are also
required. Also, the impact on the existing/ adjacent structures should be assessed and remedial
2
works need to be undertaken, which involve multitudes of site and desk studies, e.g. in
geotechnical, material technology, civil and structural disciplines. Hence it is quite common that
the scope of requirements might vary during different stages of design development in such
complex projects. Normally, the design phase in such projects involves conceptualization and
reconciliation of (a) client requirements, (b) project objectives, (c) demands of relevant
stakeholders and target customers/ users, and (d) other priorities and constraints. Although there
may be some similarities between different projects, repetitions are rarely considered with
respect to designs as the underlying reasons include typical one-off production practices, varying
project conditions, differing client/ stakeholder requirements, technological developments/
innovations and other value priorities. Normally, the pre-construction design works in
infrastructure projects are broadly divided into following five phases: (i) feasibility study, (ii)
preliminary design, (iii) scheme design, (iv) detailed design, and (v) tender design. In some cases,
the design consultancy works of infrastructure projects are procured through three major
packages such as (a) one key segment covering feasibility study, (b) the second one including
preliminary designs and scheme designs, and (b) the third main part including detailed designs
and tender designs. Moreover, the design management roles during construction stages such as
vetting contractors’ alternative designs and other obligated designs are arranged through separate
consultancy agreements. Over and above the systematic procurement reinforcements for
ensuring design quality, some advanced client practices have established systematic frameworks
for assessing and managing consultants’ performance, e.g. as in ETWB (2007). Moreover,
project-based partnering is considered in some good practices. In addition to various best
practices of procurement and performance management related reinforcement measures,
achieving design quality is targeted through several design audit protocols such as (i) generic in-
house design audit arrangements within engineering design consultancy organizations, (ii)
specific independent external design auditing arrangements, (iii) mandatory mechanisms for
auditing private projects, and (iv) client led auditing arrangements in public and quasi-
government projects (Palaneeswaran et al. 2008). However, some of the risks and concerns may
still remain in the traditional arrangements of distributed design teams, especially in complex
infrastructure works.

cultural alignment (such as resistance to change and intrusiveness), trust (such as lack of
confidence and ethical conduct concerns), management commitment from both sides, lack of
knowledge/ experience, competitive concerns (e.g. Monczka et al. 2000; Sharifi and Pawar,
2002). Moreover, with the advances in information and communication technologies, virtual
collaboration environments (e.g. Monell and Piland, 2000) and alternative workspace strategies
(e.g. McGregor, 2000; Gill, 2006) are being increasingly considered. Especially, the virtual
collaborative engineering aims at suitable integrated electronic environment for supporting
design development, e.g. with multiple design teams located at various geographically
distributed locations. Ideally, such virtual collaborative environments are expected to provide
convenient arrangements for virtually co-located multi-disciplinary collaborative design space
(e.g. Lee and Gilleard, 2002).
The designs in construction projects require both collaboration and co-operation between
different parties and the design collaborations require a higher sense of working together in order
to achieve successful outcomes (Kvan, 2000). Previous studies such as Fullerton and West
(1996) and Appelbaul and Steed (2005) analyzed the factors of clients and consultants working
together in project systems. Similarly earlier research such as Moore and Dainty (1999)
recommended integrated project teams for the construction industry. Moreover, several best
practices and industry wide reform initiatives such as Latham (1994), Egan (1998; 2002), Tang
(2001), and Constructing Excellence (2004) reiterate for integrated project teams in construction
industry. Thus, the success stories of some enlightened clients highlight the benefits generated by
integrated project teams with trusting relationships such as in the projects of British Airport
Authority (Wolstenholme, 2001; Sweet, 2008) and Hong Kong Mass Transit Railways
Corporation (Bayliss, 2000; Bayliss et al. 2004) and the Australian National Museum (Walker et
4
al. 2000). Furthermore, earlier research such as Humphreys et al. (2003) reiterate pre-
construction collaborative relationships in addition to project partnering (Larson, 1995) and
relational integration with contractors (e.g. Palaneeswaran et al. 2003; Rahman and
Kumaraswamy, 2008) as well as partnering in maintenance stages (Espling and Olsson, 2004).
Drawing threads from such integrated project teams and relationship building measures, co-
located design teams in integrated design office arrangements are considered as useful in large/
complex infrastructure projects. In co-located integrated design team office arrangements, the
clients and other project team members can effectively enforce various measures to improve the
project performance and best value.
The design teams faced several challenges in this project. Locating one of the stations over an
existing nullah set some technical challenges for the engineering design, which was well
coordinated among different disciplines (such as drainage, geotechnical and structural) and the
conflicts were effectively resolved for sound decisions. In addition, providing the station
adjacent to the depot and still avoiding the depot entrance track was effectively resolved. Yet
another major challenge was on the aesthetics aspects. The architectural design teams
responsible for station design and property development worked towards consensus decision
regarding such matters. Retail podium and station entrances were also complex and crucial. The
station entrances were suitably located to attract the residents and customers of the said
development as well as the adjacent housing estates. Thus, the station has been made easily
accessible by the all the nearby residents and shoppers. Moreover, careful planning and
interaction with various stakeholders such as different government departments and utility
companies were required to achieve effective design solutions.
The critical challenges regarding air-conditioning and ventilation of station concourse were also
quickly resolved in the integrated design team arrangement. The station an elevated one, with
5
platform level above the concourse, was originally designed without air conditioning. A steel
roof above the platform was proposed with louvers to allow natural ventilation. The station was
located at the west end of the depot supporting property development above. The location of the
station was so chosen in order to keep the station away from a set of depot entry tracks between
the mainline tracks. For this scheme, relatively a shorter length of station was adequate. As the
station was originally designed as non air-conditioned, corresponding air-handling unit rooms
and associated requirements were not necessary, and few plant rooms would have been adequate.
However, this above-mentioned station layout was subsequently revised, as it did not fit well
with the requirements of other designers and stake holders. The electrical and mechanical
engineers though did not have serious technical comments on providing a non air-conditioned
platform at high level, they categorically pointed out that providing a non air-conditioned
concourse facility would be very difficult. The headroom available for the concourse - located
between the public transport interchange at ground level and a platform at high level - was low.
Platform level was dictated by rail alignment level of the whole system, and could not be raised.
Moreover, adequate natural ventilation would not be available with the existing estate on one
side and the proposed development on the other side. Hence, the rise in temperature would be
more likely within the concourse. All such concerns favored for air-conditioning of the
concourse floor. Following this development, the station planners also felt that if the concourse
would be air conditioned, the platform should be air conditioned as well; otherwise the passenger
climbing to the non air- conditioned platform from an air-conditioned concourse would feel a
sudden discomfort. The discomfort might be multitude if the passengers had accessed the
concourse from the shopping mall or retail area. The issue was quickly resolved through the co-
located integrated design office meetings. Finally, extending the length of the station was
required to accommodate the additional plant rooms. Figure 1 portrays the representation of
original scheme before resolving such design issues in this case-study.
In addition, the property development designers requested that the station be moved eastwards to
allow the front elevation of the retail area at the west end can be vividly seen, and not blocked by
the station. As a result, the station was moved eastwards for aesthetical reasons and also enlarged
to house the additional plant rooms required due to air-conditioning. Owing to which the depot
entrance tracks mentioned above fell within the station. It was then considered to move the depot
entrance tracks further eastwards, and the station design was further revised. But due to
alignment problems, moving the depot entrance tracks was found not feasible. As such,
entertaining the depot entrance tracks within the platform area became necessary; plant rooms
previously located between the upstream and downstream tracks had been moved upwards
creating a new plant room level. Thus, the station had to be enlarged both horizontally and
vertically. All these issues were quickly identified and resolved with requisite inputs from
several disciplines e.g. civil, architectural, structural teams of both railway and property
development designers. The project team members working in the integrated design office met
and discussed conveniently. All the significant risks, constraints/ limitations and inter-
disciplinary issues were thoroughly discussed and effective mitigation measures were quickly
evolved. Resolving issues in this manner is much different to the conventional system of each
designer stationed in their works stations, meeting only during the biweekly design meetings.
In another case study of co-located integrated design team office for infrastructure works,
detailed design for additions and alterations to one of the existing busy railway stations is
discussed. A new plant room was necessitated to tie-up with some modifications to the station,
and this was proposed to be constructed underneath one of the station entrances. To facilitate the
construction, the entrance had to be demolished, and subsequently rebuilt. The opportunity was
used to upgrade the entrance located near a landmark in Hong Kong. An iconic glass box with
full height glass panels and glass roof was proposed. An unobstructed view from the adjacent
road crossing was also planned for. Some of the design issues as per the initial condition are:
(i) The canopy was proposed with structural beams and glass panel frame work to withstand
the wind load
(ii) To improve the structural stability mid-level beams were proposed. This was necessary as
the size of the four corner steel columns was restricted.
(iii) An existing retaining wall behind the glass-box was proposed to be kept, with the aim of
not affecting the existing features to possible extent. Also, the owner of the wall is
different from the railway operator.
(iv) Owing to (iii) the rear column was located above this wall, and was short.
The co-located design teams included consultants from various disciplines such as civil (as
project coordinator and for civil engineering issues), architectural (for addressing functional and
aesthetical design issues), structural (for structural aspects), electrical and mechanical (for
building services designs), system (for cabling and signaling), and façade specialist (for glass
curtain wall designs). In the integrated design office arrangement, design management was
through effective design meetings and efficient coordination between various specialties.
Routine inter-disciplinary meetings were held every week. More formal and informal
communications were considered for real-time coordination. Up to date drawings and design
details were stored in online electronic formats for 24/7 access through intranet and secure server.

After quick revision considerations in the co-located design office, the glass façade specialist
consultant came forward to provide structural glass for canopy, with special joints. Steel beams
for canopy were thereby avoided, and scheme looked close to the originally contemplated design
in this regard. The end columns were increased in size and also their structural thickness were
adjusted accordingly. This enabled the structural engineer to get rid of the intermediate beams,
and also control the sway within the specified limits. The revisions improved the unobstructed
view as well. Following this coordinated design revisions, the civil engineer liaised with the
client and also the owner of the rear side retaining wall. Subsequently, he proposed a
construction sequence to demolish and rebuild the retaining wall, and also extended the rear
column down to the ground level. Thus, the shortcomings in the original design were quickly
realized and fixed. Appreciation of the architectural intent and providing solutions by the civil,
structural and specialist consultants enabled the team to attain good results. Figure 2 portrays the
key details of initial condition, interim developments and final solution of design issues in this
second case study.

As a part of the ongoing research, a structured supervised questionnaire on rework and changes
in design consultancy works was also conducted and project-specific observations from several
building projects and infrastructure works were consolidated (e.g. Palaneeswaran et al. 2007).
Table 1 presents a sample set of beneficial pointers consolidated from couple of infrastructure
projects that adopted integrated design team office arrangements for effective design
management. Both these case-study projects adopted integrated design team office with several
convenient arrangement such as SharePoint TM based electronic project management system,
some common purpose software and hardware facilities, and client organization’s identity and
services (e.g. email, intranet, office space, overheads).

Overall, the observations from this research on integrated design office usage for the
infrastructure project developments indicate that the total design development time periods in
such projects were more efficiently managed while higher design quality performance was also
achieved. Especially, the co-located design team arrangement enabled timely identification of
design related risks and subsequent fast-tracking of relevant solutions. Moreover, the conflicts
among various disciplines were effectively resolved through the convenient arrangements of
integrated design office settings. Furthermore, more dynamic interactions with the client and
principal stakeholders enabled successful design management outcomes in this case study
projects.
decisions. The main rationale to consider an integrated design office arrangement for large/
complex infrastructure projects include: effective design development through efficient
management of time and costs, increased flexibilities, improved design quality, enhanced
constructability potentials, reduced rework and wastages, lesser conflicts and changes, and
optimal project costs. However, the strategic choice of such re-engineered co-location
arrangement of design teams and client representatives in integrated design office for a particular
project should be based on systematic assessment of relevant needs. Moreover, with additional
standardization (e.g. design information), integration (e.g. electronic project management
platforms), promotion (e.g. client-led innovations and top-down management initiatives),
motivation (e.g. bottom-up support) and training the virtual co-location could be effectively
considered.
