Level 3 Flashcards
Tell me about the impact of different design solutions and construction processes on cost and programme.
Different design solutions and construction processes play a critical role in shaping the costs and programme of a building project.
*complex designs and specialised materials can increase both cost and time.
*modern methods like prefabrication, modular construction, or automated techniques often provide opportunities to reduce time on-site, manage costs more efficiently, and improve project outcomes.
A building surveyor should carefully evaluate these factors in collaboration with the project team to ensure the design and construction methods selected align with both the client’s budget and desired timeline.
Tell me about your advice on the selection and application of particular processes within your area of experience.
For a primary school refurbishment, the focus was on upgrading classrooms, sports halls, and energy systems while ensuring minimal disruption to staff and students. Key steps included:
Understanding the Project Scope: Prioritizing upgrades like energy efficiency, air quality, and accessibility while minimizing disruption to the active school environment.
Health and Safety Management: Ensuring site segregation, scheduling noisy tasks outside school hours, and implementing clear signage to protect children and staff.
Compliance with Regulations: Adhering to Building Bulletin 100, Part L (Energy Efficiency), and Part M (Accessibility) standards for schools.
Risk Assessment: Addressing hazards like noise, dust, and asbestos, ensuring safe work practices and proper PPE for contractors.
Communication and Coordination: Regular meetings with school staff, the local authority, and contractors to align on progress, disruptions, and safety measures
How have you liaised with specialists and consultants to develop project specific design and construction solutions?
*HVAC (heating, ventilation, and air conditioning) system and lighting design)
*Assess the integrity of the building’s framework.
*R&D Survey
I identified early on that to develop a suitable design, we would need input from specialists.
Structural engineer - ensure the proposed solution maintained the building’s aesthetic qualities and complied with regulation
M&E consultant -existing systems and propose an upgrade to improve energy efficiency and occupant comfort
Talk me through how you have reported on the impact of different design solutions on cost of a construction project.
Modular v Traditional build
*Typically, modular construction can be more cost-effective than traditional new builds in terms of initial construction costs than traditional
*Cost range are lower than traditional build
*Modular construction saves on site labor, equipment, and construction time, all of which reduce costs compared to traditional builds.
*Lower Site Costs: With fewer materials and equipment on-site, the costs related to waste disposal, utility setup, and other site-specific elements are often reduced.
*require more frequent maintenance over time, particularly if the building’s quality is compromised by lower-grade materials or poor assembly.
*Expected Lifespan: Modular buildings typically last around 30-50 years, but some may have shorter lifespans, leading to potential higher costs for future upgrades or replacements.
Talk me through how when you have reported on the impact of different design solutions and construction processes on programme.
Modular V Traditional
*Faster delivery construction can happen in parallel with site preparation
*Time savings
*Quick on site assembly
*Quality Control
Talk me through when you’ve advised on the choice of construction solutions for your project.
Refurbishment of an existing office was inefficient (HVAC) additionally the windows were single glazed.
*in consultation with an M&E specialist looked at the design of a new system that was efficient
*advised installing double glazed units
*upgrading the existing fire protection systems to comply with building regulations
*LED lighting with motion sensors to reduce building’s carbon footprint and operating costs,
balancing client needs, regulatory compliance, and cost-efficiency.
Talk me through when you have advised of potential programme reduction in respect the construction of a work package or activity.
Introducing strategies such as overlapping activities, prefabricated solutions, and extended work hours, I helped streamline the construction process and ensured that the project met the client’s deadline.
*a reduction in programme can have negative affect by increasing costs.
Talk me through a value engineering you’ve carried out during a construction project.
School Refurbishment -
Lighting - alternative manufacturer and motion sensors in common areas only
Interior finishes - substituting the flooring manufacturer
Ceiling tiles - substituting the flooring manufacturer
How have you advised on design where the methods of construction or materials have had a significant impact on project cost?
Material selection
High-End Finishes vs. Standard Materials
-flooring
-lighting
-alternative M&E Systems
- alternative roofing systems felt, liquid applied
Construction Method Selection and Time Saving
Traditional v Modular
Evelyn Primary School -How did you prepare layout plans? Why did you require a structural engineer to inspect the roof? To which extent did the roof need replacing and why?
Measuring the space: I take precise measurements of the existing structure, noting dimensions such as wall lengths, ceiling heights, window and door placements. When designing the layout I had to consider the following:
*Building Regulations - fire safety, means of escape, and accessibility
*Health and Safety Standards - adequate space for safe movement and the necessary facilities (such as toilets, escape routes, and ventilation).
Water ingress can weaken the structural connections between modules, especially if the water penetrates through joints or seams. This may cause the roof to become unstable or uneven over time.
Why did the Work need to comply with building regulations? What impact did this have on existing construction details?
Refurbishment brings the modular building up to current building regulations as they may have changed since the original construction. With regards to:
fire safety - fire alarm system that was linked to the main school, fire doors
energy efficiency - Lighting, roofing, windows and walls Part L
accessibility - ramped access (equality Act)
thermal performance - Roof upgrading the insulation on the existing roof
Millbrook - What was the advantages of over boarding the existing wall? Can you talk me through hygienic board? What was the outcome of your advice and why? How did you assess the costs?
Provide clean, smooth, and durable surfaces, particularly in environments where maintaining high levels of hygiene is essential. they are:
*Non-Porous and Easy to Clean
*Waterproof and Moisture-Resistant
*Durable and Impact-Resistant
*Antibacterial and Anti-Fungal Properties
*Easy to Install
Weighed - material vs labour costs of tiles and sani clad.
