- Let in a shell condition with no shop front, ready for the retailer’s fitting out work.
What institutional specifications of offices?
- Two main methods are either steel or concrete frame
- Steel frame buildings usually have fewer columns and a wider span between the columns
- Concrete frame buildings usually have more columns, lower floor height and a shorter span between columns
- Check the architecht;s drawing and specificcation or building manual if you cannot see what form of construction it is on site.
Current specification may include:
- Full access raised floors with floor boxes
- ceiling height circa 2.6 - 2.8 m
- Ceiling void of 350 mm and a raised floor void of 150 mm
- Air conditioning
- Double glazed windows
- Passenger lifts
- 1 cycle space per 10 staff, 1 shower per 100 staff.
- Opportunities for daylight 300-500 lux average
What types of Office fit out are there?
Shell and Core - where the common parts of the building are completed, and the office floor areas are left as shell
Category A - Fit out to Grade A
- Category B - Fit to occupiers specific requirements such as installing cellular offices
- Cellular offices are usually set out on a 1.5m planning grid
- Typical space allowance for normal office use is approximately 1 person for 7.5 - 9.25 sq m.
What is the institutional specification of an industrial warehouse?
Basic construction is typically steel portal framing with insulated profiled steel cladding walls and roof.
- Minimum 8m clear eaves height with 10% roof lights.
- Minimum 30 KN/sq. m floor loading
- Plastic coated steel profiled cladding with brick or blockwork walls to approximately 2m.
- Full height loading doors (electrically operated)
- 3 phase electricity power (415 volts)
- 5-10% office content with WC Facilities
- Main services are capped off
- Approximate site cover of 40%
- LED lighting
What is a inherent defect?
A defect in the design or material that has always been present.
What is a latent defect?
A fault to the property that could not have been discovered by a reasonably thorough inspection of the property. (Hidden) (E.g. defective steelwork or concrete columns that are concealed under the finishes.
You are inspecting a property and identify a defect. What four steps should you take?
- Photograph the defect
- Try establish cause of damage
- Inform the client
- Recommend a building surveyor or for movement a structural engineer.
What are three common causes of defects?
- Movement
- Water
- Defective / Non-performance / deterioration of building materials
What is subsidence?
The vertical downward movement of a building foundation caused by the loss of support of the site beneath the foundation. This could be as a result of changes in underlying ground conditions.
What is Heave?
The expansion of the ground beneath part or all of the building. (opposite of subsidence, pushes ground up).
This could be caused by tree removal - when the tree is gone it’s roots aren’t absorbing the water, so there becomes a moisture build-up in the soil.
What does horizontal cracking in brickwork indicate?
A cavity wall tie failure in a brick wall.
When does shrinkage cracking occur?
Often in new plasterwork during the drying out processes.
What can cause cracking?
- Shrinkage cracks
- Horizontal cracking form wall ties
- Strucural movement (Heave/Subsidance)
- Movement or settlement cracks
- Thermal expansion/movement
