Environmental Science & Services

Paper, Order, or Assignment Requirements

 

 

Task 1 has to be 2200 words (+/- 10%).
Task 2 has to be 800 words (+/- 10%).

About task 2, only the ADT part has to be done, because I’m an ADT student. So it’s only the ADT section that has to be done in task 2.

1. TASKS

 

TASK 1 – 2200 words +/- 10% (typically 6 – 8 pages excluding tables, etc.)

 

1. a) – Examine the whole building and provide guidance for use by the Building Services Engineer in the design of Mechanical and Electrical Services that might be installed in the building to meet the ‘Environmental Comfort’ criteria the building’s occupants should expect. In terms of this assignment Environmental Comfort criteria are defined as physical data that are sourced from approved regulations and/or guides and that are demonstrable/measurable in some manner to confirm their achievement at the M&E services commission stage of the construction project. The data selected should be relevant to the needs of Task 1 parts b), c) and d) below. Include fully cited and referenced tables, charts, graphs, etc. to back up your guidance. (1 – 1 ½ pages excluding tables, etc.)

 

1. b) – Determine by one calculation only, and a subsequently developed ‘Rule of Thumb (ROT)’, typical steady state heat losses from all offices and internal spaces on the ‘Intermediate floor’. Calculate the General Office on the Intermediate Floor and use the derived ‘ROT’ to determine heat losses for all other offices and internal spaces on that floor and the remaining four floors (note all assumptions made). Discuss how a resultant whole building heat loss calculation would be used in a real project. Calculation procedures will be covered in module lectures. (1 – 1 ½ pages excluding calculations, tables, etc.)

 

1. c) – Carry out a lighting design using the ‘Lumen Method’ for the Retail Area on the ground floor. The luminaire selected for the design is your choice and its selection must be justified by you. In particular, identify and discuss what information is missing from the drawing that a real designer would need in order to calculate and optimise the design. Include manufacturers’ literature as appropriate to illustrate the data used in producing your design. Use photos as appropriate (fully titled and cited) to illustrate the kind of design you would wish to achieve in a real project giving the reasons behind your proposals. Calculation procedures will be covered in module lectures. (1 – 1 ½ pages excluding calculations, tables, photos, etc.)

 

2. d) – Examine the ground floor layout in relation to the location of Lecture Theatres 1 and 2. Discuss any acoustics related conditions you perceive might be a problem and propose ideas to alleviate those problems. Consider both internal and external noise and vibration sources. Use manufacturers’ literature as appropriate to illustrate some/all of your proposed control measures. (1 – 1 ½ pages excluding calculations, tables, etc.)

 

 

TASK 2 – 800 words +/- 10% (typically 2 – 3 pages excluding calculations, images, etc., if they are included)

 

Task 2 depends upon your study discipline as follows:

 

ADT

 

Aesthetics – Building services may be regarded by some as a ‘necessary evil’, an eyesore within a beautiful space. How do we hide building services? If they cannot be hidden what can be done to make them less noticeable? Do we in fact need to hide them – cannot they be integrated and made part of the occupied environment?

 

Task 2 ADT – Examine the Entrance Foyer and Reception on the ground floor. Discuss from the ‘aesthetics’ versus ‘functionality’ viewpoint how the heating and lighting of these two spaces can be accommodated to the satisfaction of both the Architect and the Services Engineer. Use numerous photos from various research sources to support your thoughts, ideas and proposals. (Note all assumptions made).

 

QS

 

Costs – ‘Building Engineering Services’ are now a major cost component of the total cost of a building project. It is not unknown for the services to account for 30% to 60% of the total. Some clients and contractors, in an attempt to reduce project costs, employ ‘Value Engineers’ whose role is to analyse the whole project from design through to commissioning with a view to reducing costs whilst still maintaining standards and quality.

 

Task 2 QS – With standard M&E components in mind (e.g. boilers, air handling units, luminaires, etc.) investigate from a ‘Value Engineering’ viewpoint how the overall M&E costs for the given building could be reduced in practice and identify the positive and negative aspects of such an approach to building services procurement. (Note all assumptions made).

 

BS

 

Services Maintenance – In the past the maintenance of a new build project was not given much thought during the design stage – it was often not considered as the design teams remit to think how the building might be maintained over the next 15, 30 or even 60 years. This lack of consideration of the building’s total ‘life cycle’ often caused maintenance staff big problems in later years.

 

Task 2 BS – Using available guidance and data as appropriate, suggest how the total maintenance costs of the services installed in the given building could be reduced in practice. Consider both the design and operation of the services over a 30 year period. (Note all assumptions made).

 

CPM

 

Project duration – The traditional construction works sequence leaves services installation towards the end of the project and hence any delays caused during the prior building work can have severe consequences for services sub-contractors in terms of installation and commissioning  durations being compressed under pressure from main contractors/clients.

 

Task 2 CPM – Investigate and analyse how services installation can be ‘speeded up’ in this project building. Briefly examine one aspect for each of:

 

1. a) Services plant rooms,
2. b) Services distribution, and
3. c) Services emitters, diffusers and luminaires.

 

(Note all assumptions made).

 

Please note that any project drawings that you wish to use as part of your submission must be scanned in to the finished document to allow for electronic submission.
