2. WRITTEN ASSIGNMENT
Question 1:
PRE_LINE CHECKLIST:
Refer to the ‘pre-line checklist’ in the in the ‘Inspections’ Chapter of the Resource Book: Choose 5 items from the checklist and identify exactly what are the building requirements to pass the pre-line inspection.
Questions from the GIB Installation checklist;
Has the framing surface been checked for flatness? i.e no protruding nogs, lintels etc
Is the moisture content acceptable? (18% or less)
Are grooved jams set up correctly to allow 1 – 1.5mm clearance for sheet edge?
Are ceiling battens running in the same direction within room spaces?
Also substrate accepted by fixer.
The building requirements to pass the pre-line inspection are;
Exterior cladding in place and is weathertight
Bottom plates have appropriate bracing elements in the right place and as per approved plans
Bottom plate fixings are correct
Floor plan as per approved plans
Lintel/Beam’s as per plan with appropriate fixings
Fixings for high wind (If applicable)
Air gap backing rod and foam installed correctly
Insulation in ceiling/walls installed with correct ratings.
Question 2:
CONSTRUCTION MOISTURE:
Identify the strategies a builder could employ to control construction moisture.
There are several things a builder has to watch out for when it comes to construction moisture when building houses, such as rain and water, dampness during the build and products that might arrive on site with water in them. But for all of these problems there are things that a builder could do to achieve a controlled construction moisture method while on site, such as leaving wet timber stacked on fillets to dry, after building wrap, windows and exterior cladding have all been successfully installed, the builder could get some airflow going through the house using vents and windows. Also for a quicker method of drying out framing, use a hot fan as heat will dry out the frames quicker.
Question 3:
INSULATION:
Investigate 3 types of commonly used ‘thermal insulation’ available for timber walls and ceilings.
Bradford Gold® insulation is a resilient & compressible insulation manufactured from the controlled felting of glass wool bonded with a thermosetting resin. Benefits of Bradford Gold include reducing energy costs by keeping heat out in summer and heat in during winter, specifically stiffened for use in wall applications, specially treated with a water repellent to increase the ability to repel water which gives added protection to internal walls from water damage, pieces are supplied in 580mm widths for 600mm stud centres & can readily be cut to fit other stud spacing, has a guaranteed R-Value and complies to AS/NZS 4859 & carries a lifetime guarantee. It is designed to reduce unwanted noise;
-Entering through external walls
-Between rooms within the house when installed into internal walls
-Between floors when installed into mid-floor and under floor applications
