c) steps to be taken prior to commencing erection, and A:

A:
•Ensure appropriate lifting equipment is used, which should be referenced in the shop drawing.

•Maintain communication between the crane operator and the dogger to help ensure that the crane does not move away prior to the lifting equipment being disconnected from the panel.

Choosing Dincel polymer formwork:
Dincel Structural Walling is an internationally patented permanent polymer formwork for walls and columns, which when filled with ready mixed concrete, produces an economical, strong, durable structure. It is one permanent formwork option available in Australia that claims to be a fast, cheap, and easy alternative to block/brickwork and precast and in situ concrete building methods.

Its fire ratings, combustibility, waterproofing, earthquakes, acoustics, toxicity and VOC testing. are certified BEP Approved (Best Environmental Practice) on the use of PVC recycled material during manufacturing and end of life management for sustainable buildings in construction.

FRL (Fire Resistance Level)
The formwork material is comprised of certain additives which enhances fire performance. In the event of a fire, the material safely chars and intumesces. The solid concrete within provides the necessary fire rating. Warringtonfire and CSIRO have confirmed that the polymer webs do not melt away or negatively affect the concrete wall’s performance for FRL. As such, in accordance with AS 3600, a Dincel wall can achieve up to 90/90/90 for 110mm up to 240/240/240 for 275mm.

•Finishing a polymer based permanent formwork wall can mean rethinking your waterproofing, adhesives and coatings, cladding materials and methods.

A:
Load path extends from the roof through each structural element to the foundation. The load path can be identified by considering the elements in the building that contribute to resisting the load and by observing how they transmit the load to the next clement. Depending on the type of load to be transferred, there are two basic load paths:
•gravity load path
•lateral load path
Both the gravity and lateral load paths utilize a combination of horizontal and vertical structural components and explained as:

H: Hold Point = Hold on the production till TPI Inspector performs inspection and supervise the required test
W: Witness Point = Manufacture shall notify client and TPI Inspector but there is no hold on the production;
Client can waive this inspection based on his discretion and informs TPI Inspector accordingly.

R: Document Review = Review means Review document, which includes of material test certificates, WPS, PQR, NDT Procedures and etc.
