ASSESSMENT

PROJECT – BUILDING SERVICES DESIGN, DOCUMENTATION, INTEGRATION, COMMISSIONING & BIM

RATIONALE:

As a construction professional you will be working in a context where you will need to manage the construction, costs and/or compliance of building services for construction projects. Although you may not be required to directly contribute to these services, you will need to know how to interpret plans, check compliance, monitor costs and interrogate BIM models as part of your professional life.

This project helps you to build the skills in reading and interpreting building services documentation and using BIM models for specific contexts and potential projects, so this assessment uses a scenario-based design to make the application of your knowledge relevant to the real world.

COURSE OBJECTIVES:

• CO 1 Demonstrate the scientific principles which underpin the operation of specific building service engineering functions.

• CO 2 Interpret the design and operation of supply services in domestic and commercial construction.

• CO 3 Assess the design and operation of conditioning internal environments and other engineering services systems in multi-storey buildings and the implications that such systems have in the construction process.

• CO 4 Summarise the building surveying context of building services.

• CO 5 Display information on building service engineering functions using Building Information Models individually or in teams.

ASSESSMENT DESCRIPTION

PART A: DESIGN AND DOCUMENTATION

SCENARIO

You are newly employed staff member at SEBCET, a company that manages building services throughout the project lifecycle. The company is contemplating extending the use of BIM in its operations. To demonstrate to the management team that you understand the design and documentation requirements for building services you have been asked to prepare a small report for the management team.

You need to conduct a background review of the literature using library resources related to the building services industry and prepare a response to the following:

1. Prepare a list of the various statutory authorities in your jurisdiction and their respective roles in relation to electrical, mechanical and hydraulic services provision. Selecting one of the statutory authorities, describe in detail how the project design team and the construction team interact with this authority (250 words).

2. Explain how building services modify the indoor environment considering criteria such as daylight, ventilation, thermal comfort, glazing, building fabric and internal noise levels (250 words).

3. Discuss how building performance and regulatory requirements affect the design of building services (250 words).

4. Design the air-conditioning system of this building by considering the provided instructions in the course website.

The building is a call centre in Katherine.
The room floor area is 1800 m².
Assume a room cooling load of 200 W/m²
Total Cooling Load, with a 30 W/m² Latent Load and occupancy of 1 person/8 m² gross.
The outdoor Air Condition is 39.1°C DB and 26.9°C WB.
Supply air condition is 12°C and an outside airflow rate of 15 L/s/person (ignore fan gains)
and chilled water to the coil at 6°C flow and 12°C return.
Design Room Temperature of 23°C DB and 50% RH.

Assume the cooling coil has an air off relative humidity of 90% RH (or coil bypass factor of 0.9).

5. Produce a schematic for the air conditioning system, assuming a single cooling coil, supply and return fans, mixing damper arrangement and outside air intake/discharge louvres (fans in a draw-through arrangement)

6. Produce a psychrometric chart for the cooling process (assume a single coil system with recirculation):

Plot inside and outside air conditions.

Plot Cooling Coil Apparatus Der Point.

Plot Air Mixing Process Line and Mixed Air Condition.

Plot Cooling Process Line and Plot ‘Air Off Coil’ Condition.

Mark up Coil Enthalpy Δh

7. Calculate the total room cooling load in kW.

8. Calculate the latent room cooling load in kW.

9. Calculate the sensible room cooling load in kW.

PART B: INTEGRATION, COMMISSIONING AND CLASH DETECTION

SCENARIO

As a SEBCET staff member, you are asked to investigate the building services for an 8 x 5 m meeting room in an office building. The ceiling void above the room has 600 mm (clear height) needs to contain the following service systems:

• Fluorescent lighting system, flush mounted, for general space illumination.

• Spotlight system, for artwork on the two side walls.

• Speaker system.

• AV projection system, to one end wall.

• Ducted air conditioning system, insulated.

• Sprinkler system.

• Smoke detection and alarm system.

• Wastewater drainage system (serving the space above).

• Hot and cold-water supply system (serving the space above).

In addition, this room contains two parallel reinforced concrete beams 300 mm deep x 300 mm wide, running across the room. The floor over the ceiling void is a reinforced concrete slab.

Prepare a report to SEBCET that contains

I. A draft reflected ceiling plan for this room

II. The issues to be considered in the laying out, installation and maintenance of the services. Consider the services one at a time, and collectively. Consider sequencing, support, clashes, appearance, access, and so on.

III. Recommended ceiling systems that would suit this situation, with reasons. Include in your report how this decision will impact the services, and vice versa.

Clearly state any assumptions that you have made.

Prepare your response as a word document. Submit your response in Week 10.

PART C: INTERROGATING A BIM MODEL

SCENARIO

The final task that you are given as SEBCET staff member is to demonstrate your skills in utilising BIM to effectively support the display of building service engineering functions.

To complete this part of the assessment you will need to download a BIM model from the Assessment 1 Resources folder and interrogate the model as described below. You will also need to capture your screen (e.g. Print Screen or Windows snipping tool) at appropriate times to demonstrate that you have performed the various investigations. Insert the images into a word document, annotating as required to provide a report of your interrogation.

I. Hide the roof & sisalation that sits under the joists exposing the ceiling ductwork. Create a viewpoint of this exposed ceiling and mark it up highlighting a section of each of the following:

• Rectangular ductwork

• Flexible ductwork

• 300x300 exhaust air eggcrate grille

• Plenum box

• Light fitting.

II. Section an elevation of the building, then create a viewpoint of this section and mark it up showing a section of each of the following:

• Universal steel beams supporting upper floor

• A glazed curtain panel

• Glass sliding door

• Compound ceiling

III. Section the roof off the building exposing the ground floor plan then create a viewpoint of this section and mark it up showing a section of each of the following:

• Plasterboard basic wall

• Panel basic wall

• System panel glazed

• Plumbing fixture – WC

• Plumbing fixture – hand basin

IV. Section the floor off the building showing a ground or first floor reflected ceiling plan and mark it up showing three (3) of each of the following pieces of equipment:

• Supply Grilles

• EWIS speakers

V. Create a viewpoint of the roof and mark it up showing one of each of the following:

• Daikin condenser

• HWU

• Laboratory fume exhaust

• Introduction

• Materials and Methods

• Results

• Discussion on the interrogation of BIM models for building services

• Conclusion
