Exercise A on your scenario of the future ICT supported building process

A scenario is an analysis of challenges and future possibilities for development. The scenario will help us to communicate and gain insights in future developments. It should be as objective as possible taking into account evaluations and analyses of viable future ICT developments and organisational and work environment changes. The scenarios are stories and do not talk about specific technologies in depth but try to develop a story about what people must do in order to complete their task or goals.

A building future scenario could well be developed by a group of people with insight and experience in different areas such as engineering, architecture, building operation and ICT experts.

Exercise B on conceptual modelling of your semester 7 project

1. Define the overall function(s) of the system under consideration. Use initial needs and wishes expressed by the client
   
   
2. Try to give names on the system and it's subsystems.
   
   
3. Choose the system and subsystems you intend to model, design, and implement.
   
   
4. Start the modeling work by drawing rich picture conceptual models starting on top level.
   
   
5. Draw a top level process model using IDEF0 diagram.
   
   
6. Sketch a Work Flow diagram for a system use case. Use Contextual Design methodology.
   
   
7. Sketch a Sequence Model for the same Use Case. Use Contextual Design methodology.
   
   
8. Sketch a User Environment for the use case (involving one or more users). For example as screen dump(s) from the hypothetical system. Protoype ver 0.1
   
   
9. Evaluate the system prototype version 0.1 with the user.
   
   During continuous evaluation and discussions with end user, the user needs and requirements are specified in more detail. UML models that are partly derived from the Contextual design models can support the software design and implementation.
   ...
   
   
10. Discuss what possible UML diagrams can be constructed during implementation.

Exercise C on database design and web access

• Based on different roles, try and test the project web system Byggeweb. (each group member has a role (contractor, architect, client, engineer etc.)).
• Describe the flow of documents and compare with the database developed in part 1.
• Reflect on (write 1/2 A4 page) how this technology, models, and information containers [project webs] could be used in building projects, to support company costumer relations and company knowledge management.
  Sketch on a needs and requirements specification for a company project web.
• Finally present your solutions to other groups.

• Design a relational database that based on a fictive building project can coordinate and store involved companies, persons, the person's competencies and documents related to the building project.
  [You may also use the results from semester 6 exercise, previous exercises or part of your semester project to make a conceptual design of a relational database (by your project company or end-customers).]
• The database should contain five or more related tables (e.g. companies-employees-competencies etc.)
• Implement the database using Microsoft Access.
• Test database access using the in built possibilities to make forms in Access.
• Document your design and database queries.
• Explain/try-out how the SQL calls can be transferred to the database (in two or more html/ASP-files to access the database via a Internet Information Server (IIS) or Personal Web Server (PWS) from a web-browser).

Exercise D on Knowledge representations

1. Virtual Building models
2. Document handling
3. Experience Capture
4. Meeting notes
5. your own suggestions....

Exercise E on meta structuring of information using XML and RDF

Part 1

1. Filerne ex_e.xml, ex_e.xsd og ex_e.xslt gemmes lokalt på harddisken (vær opmærksom på filendelserne: .xml, .xsd, .xslt.)
2. Via en tekst editor (fx WordPad da denne beholder formateringen) dannes et overblik over ex_.xml filen og der tilføjes en etage (storey) med min 2 spaces til bygning 1.
   Gem XML filen i et nyt navn.
3. Valider den nye XML fil med XML Skemaet ex_e.xsd via validatoren http://apps.gotdotnet.com/xmltools/xsdvalidator/.
4. Via editoren foretages følgende ændringer i ex_e.xsd:
   • Værdi i SpaceType skal være "entrance" i stedet for "communication".
   • Der kan maks. være 2 etager i en bygning.
5. Valider XML filen og foretag nødvendige ændringer i XML filen.
6. XML dataene skal nu formateres til HTML via et stylesheet.
   Indsæt i 2. linie af XML filen følgende: <?xml-stylesheet type="text/xsl" href="ex_e.xslt"?> og åben XML filen i en browser.
7. Lav ændringer i ex_e.xslt filen, fx. ændring af farver, skrifttyper og formateringer.
8. Dokumenter øvelsen via udsnit af koden samt skærmdumps.

Part 2

1. Hent og installer editoren RDFedt
2. Opbyg vha. RDFedt en RDF beskrivelse om en fiktiv webressource (fx http://www.test.dk/dok1.pdf), der baseres på Dublin Core Element Set 1.1
   Der skal indgå minimum 3 metadataelementer
3. Valider RDF beskrivelsen med W3C's RDF Validator
4. Dokumenter resultatet via skræmdumps og korte kommentarer til hvad der sker i koden
5. Hvordan mener I at denne teknologi kan anvendes i byggebranchen. Drag fx sammenligninger med de projektweb systemer, der blev demonstreret i øvelse C
6. Hvilke processer i en virksomhed kan understøttes af teknologierne.

Exercise F on new services in digital cities and intelligent buildings

You shall in this exercise take the role of client advisor in the intelligent building domain. The client will build a new office hotel. You should produce information to support the client in his formulation of (new types) ICT supported services and how these can be designed, implemented and used.

• list those intelligent building type of services you will present to the client
• describe how some of these services could be implemented in the intelligent building
• present a tentative requirements list on IB supported functions and services in the planned office.
• also describe how a IB design team could be composed
