Q

What are their advantages and disadvantages of concrete frames?

A

Concrete Frames
Advantage - Inherent fire protection, reduced cashflow, low maintenance, good sound and insulation, ideal for complex structures
Disadvantage - more time consuming, delicate for inclement weather. larger sizes hence bigger footings, steel reinforcement fluctuates

Q

What are the advantages and disadvantages of Steel Frames?

A

Steel Frames
Advantage - Quicker to assemble, recycable, good for long span, lighter structure hence lesser footings, invulnerable to termites, fungi
Disadvantage - Requires fire protection, Fixing and fitting maintenance, steel price fluctuates, not suitable for complex design, builders are market expensive.

Q

Is HOAI mandatory to use in germany?

A

Following a 2019 ruling by the European Court of Justice (ECJ), which found the mandatory minimum and maximum fee rates to be incompatible with EU competition law, Germany had to adjust its application. The revised HOAI, effective from 2021, provides more flexibility in fee agreements, but the fee tables still serve as a reference.

17
Q

What is a HBO bauleiter?

A

Hessen Bauordnung (Building Code) Construction Manager - must ensure that the construction measure is carried out in accordance with the requirements of public law and give the necessary instructions.

18
Q

What is the common basis of design in Germany?

A

BauGB, Bauordnung, DIN, Neufert

19
Q

What are the requirement for building permit in Germany?

A

Building Permit Application Form (Bauantrag), Architectural Plans, Site Plan (Lageplan), Structural Calculations (Statik), Energy Efficiency Plan, Project Description (Baubeschreibung), Compliance with Building Regulations, Fire Safety Plan, Drainage Plan, Soil Report

20
Q

What is the basis of sustainability measures in Germany?

A

DGNB, EPBD
- All new buildings must be NZEB by 2020, new public buildings by 2018.
- All building must be issued with EPC

21
Q

In cark park building, what are the options provided for the structural frames? What are the advantages and disadvantages? What was the selected options?

A

Traditional cast-in-situ
Full precast frame and foundation
Cast-in-situ foundation and precast frames

22
Q

How much does it cost for each options?

A

Traditional frames: 1.3M Dinar
Full Precast: 1.8M Dinars
Hybrid: 1.5M Dinars

23
Q

What is the difference between post tension slabs and hollowcore slabs? What their pros and cons?

A

Post-tensioned slabs are a type of concrete slab that is pre-stressed using high-strength steel tendons (cables) that are tensioned after the concrete is poured and has gained sufficient strength.
Pro: Reduced Thickness, Longer Spans, Material Efficiency
Con: Complex Design and Construction, Higher Initial Costs, Limited Modifications
Hollowcore slabs are precast, pre-stressed concrete slabs with continuous voids (or cores) running through their length. These voids reduce the weight of the slab without significantly affecting its structural integrity.
Pro: Weight Reduction, Speed of Construction, Factory Quality Control
Con: Transportation and Handling, Limited Design Flexibility, Connections and Detailing, Connections and Detailing

24
Q

What is the recommended option? How are the costs of each options?

A

Post tension - 70k Dinars
Precast - 61k Dinars (Recommended)

25
Q

What are the factors that affect the building lifespan of a building?

A
  • Geographic location (Extreme temperatures and soil quality can impact the structure of a home).
  • Building materials (higher quality materials often last longer).
  • Maintenance
26
Q

What are the options presented in an administrative building in Germany? How much are the difference in costs?

A

800 m2 Off-the-shell containers 2.1M, Modular buildings 3.3M, 800m2

27
Q

What are the options presented to a government client in Bahrain?

A

Normal wall painting and pigmenting concrete in a precast boundary wall

28
Q

How did you conduct the cost exercise between normal wall painting and pigmenting concrete in a precast boundary wall?

A

I conducted an cost exercise by comparing the maintenance cost of painting the precast wall and pigmenting the concrete itself, over a sample of 20 years.

29
Q

How much is the difference between the two?

A

I conducted an cost exercise by comparing the maintenance cost of painting the precast wall and pigmenting the concrete itself, over a sample of 20 years.

30
