Introduction
0.1  General
The purpose of this document is to assist city chief information officers (CIO) and other stakeholders in
planning and implementing a smart city. It comprises the following three parts:
— Part 1: Smart city business process framework
— Part 2: Smart city knowledge management framework
— Part 3 (this document): Smart city engineering framework
Each of the three parts is aimed at a different role or viewpoint within the city and thus separate focus
needs to be maintained. The "separation of concerns" is a principle for the development of a city as it
uses ICT to deliver the vision and objectives for the city. The value of using the separation of concerns
is to simplify development and maintenance of the architecture as the city both develops and delivers
improved outcomes for the city stakeholders.
Figure 1 shows the components of the smart city ICT reference framework, which consist of
5 components: stakeholders, vision and outcomes, the business process framework, the knowledge
management framework, and the engineering framework. While stakeholders, vision and outcomes,
and the engineering framework are described in this document, the business process framework and
1) 2)
knowledge management framework are described in ISO/IEC 30145-1:— and ISO/IEC 30145-2:— ,
respectively.

0.2  Stakeholders
The stakeholders served by the smart city ICT reference framework are businesses, citizens, government
organizations and non-government organizations. This stakeholder list is not exhaustive but defines
the key stakeholders in a smart city and the user for the smart city ICT reference framework.
0.3  Vision and outcomes
The motivation of making a city smart is a result of a shared vision and a set of agreed outcomes from
all of the city stakeholders. The vision and outcomes of the smart city ICT reference framework are
well-being, transparency, sustainability, economic development, efficiency and resilience, collaboration
and innovation. This vision and outcomes list is not exhaustive but defines the key vision and outcomes
of a smart city. The smart city ICT reference framework articulates a vision that the smart city will be
transparent in the delivery of city services which meet city sustainability ambitions. This vision uses
collaboration and innovation approaches to deliver desired city outcomes. City outcomes are expected
to improve efficiency and resilience of city services and promote economic development activities
which enhance the well-being of citizens.

4 Smart city engineering framework
4.1 Introduction
This document gives descriptions of a Smart city from an engineering perspective. It consists of two
parts, the horizontal engineering layers and the vertical systems. For each of the business processes
defined and categorized in ISO/IEC 30145-1, a city uses the knowledge defined by the knowledge
management framework in ISO/IEC 30145-2. Additionally, the knowledge defined by the knowledge
management framework in ISO/IEC 30145-2 is used to understand how the engineering framework is
implemented. The function of the horizontal layers is to provide a clear mapping of different techniques
and components needed for smart city business processes. The function of the vertical systems is to
guarantee the consistency of the technical implementation of a smart city.
4.2 Overview of the smart city engineering framework
Figure 2 shows the smart city engineering framework from the ICT perspective. The framework consists
of 5 horizontal layers and 5 vertical cross layer systems with 4 types of smart city stake holders. The
five layers are data acquisition layer, network communication layer, computing and storage layer, data
and services supporting layer and smart application layer; whereas the five systems are security and
privacy protection system, construction system, operation and maintenance system, identification
system and positioning system. In addition, the four types of city users are citizens, enterprises,
governmental entities and non-governmental entities. The five layers and five systems are introduced
in detail in 4.3 to 4.12 respectively.

The data acquisition layer provides the capability to sense the world and take actions. The network
communication layer consists of Internet, the telephone network, the cable television network and
their convergence. The computing and storage layer includes resources for computing, data storage
and foundation software. The data and services supporting layer fuses the data capture capability,
communication capability, data storage capability and computing capability into data management
and service management capability. The smart application layer offers smart applications and their
integrations across industries and domains with support from the layers underneath. The security
and privacy protection system addresses the security requirements of a smart city. The operation
and maintenance system addresses the ability of a smart city to operate and maintain its IT services.
The construction system addresses the ability of a smart city to transit its IT services into sustainable
operations for design, planning, construction, maintenance and other aspects of smart city needs. The
identification system provides all layers of the engineering framework with identification services.
The positioning system is one of the basic systems in a smart city providing inertial, integrated, linear,
optical and satellite positioning services.

management. This system is applicable to the design, planning, construction, maintenance and other
aspects of the ICT systems of a smart city. This includes protecting the confidentiality and rights of
[9]
individual citizens .
4.4 Construction system
The construction system provides the capabilities of design, planning, construction maintenance and
other aspects of a smart city.
4.5 Operation and maintenance system
4.5.1 General
The operation and maintenance system provides an overall plan for the operation and maintenance
services capabilities; provides necessary resources to implement operation and maintenance service
capabilities, management and services content; ensures the quality of delivery to meet service level
agreement requirements; carries out supervision, measurement, analysis, evaluation and improvement
of operation and maintenance service results and service delivery processes. Existing standards for
ICT service operation and maintenance, such as the ISO/IEC 20000 series, can be used by a smart city.
[3]
Subclauses 4.5.2 to 4.5.5 summarize that approach to service operation and maintenance .
4.5.2 Planning
Planning includes the following aspects:
1. planning operation and maintenance service objects and requirements according to the business
location and capacity, and forming a service catalogue;
2. establishing the appropriate organizational structure and management system following the
service catalogue;
3. implementing operation and maintenance team, processes, and goals, carry out personnel,
resources, technology and process planning, and establishing adapted assessment methods and a
service support system;
4. planning to manage, review and improve the quality of service, and establish internal review and
evaluation mechanisms.
4.5.3 Implementation
Implementation includes the following aspects:
1. developing an overall implementation plan, and performing according to the overall
implementation plan;
2. establishing a communication and coordination mechanism with demand-side;
3. creating appropriate documentation to ensure the traceability of implementation; ensuring
documentation results can be evaluated and measured;
4. constructing an operation and maintenance centre responsible for implementing system
monitoring, operation command, maintenance, equipment management, service response and
other functions;
5. creating the ability to monitor the operational state of hardware, control systems, applications from
the data acquisition layer, the network communication layer, the computing and storage layer, the
data and services supporting layer, the smart application layer, and responding in a timely manner.

includes the following aspects:
1. establishing an improvement mechanism;
2. analysing planning, implementation and checking triggers the loop of planning- implementation-
check-improvement.
4.6 Identification system
The identification system provides all layers of the engineering framework with identification services.
The identification services provide unique identifiers for people, places, events, etc. as required by each
layer of the framework. At the lowest level of the engineering framework, identification is facilitated
by positioning systems that are based on a common i.e. “shared” reference framework, e.g., World
[16]
Geodetic System (WGS84) . Identification of people can be as simple as country or city specific
unique identifiers (e.g., citizen ID), or as complicated as using biometric recognition technology to
identify a person with some degree of accuracy, or even more complex where fragmentary information
from multiple sources is combined/fused to hypothesize identify with perhaps an even lower degree of
accuracy. The assignment of unique identifiers by identification system applies also to events, places,
and documents.
4.7 Positioning system
The positioning system ensures that all other systems have a common idea of the spatial position
of things. Many of these positioning services will be operated outside the city architecture and will
provide a positioning servi
