BUNDLE 1
Aluminium Wall Form Systems
The core product is a modular aluminium wall form system. Panels are fabricated in standard widths and heights, faced with a smooth mill-finish skin and stiffened by integral ribs so that they hold their shape under pour pressure. Matched walers, tie rods, wedges and corner closures complete the set, and a small number of adaptor pieces handle openings, reveals and changes in wall thickness.
Because the panels are light and factory-made, a crew can set a full wall line quickly and repeat the same geometry on every floor. The system is designed for high-rise residential cores, shear walls and podium retaining lines where the same wall returns floor after floor. Chun Jet Formwork Engineering Company Limited keeps a stocked range of standard panels so that a new project can often be served from existing stock, cutting lead time before the first pour.
BUNDLE 2
Slab Table Formwork
Slab table formwork carries the soffit of the floor plate. Large flying tables are assembled in the yard with their own trusses, joists and plywood or aluminium faces, then lifted into position by the tower crane and re-used floor after floor. Hand-set slab panels cover the smaller areas that a table cannot reach, such as balconies, lift shafts and edge strips.
The skill lies in dividing the floor plate into table sizes that the crane can safely fly and that suit the column grid. Chun Jet Formwork Engineering Company Limited plans each table layout against the structural drawings, checks the loads, and details the props and sears that support the tables during the pour. Good slab planning means fewer loose pieces on the deck, faster cycles and a flatter soffit.
BUNDLE 3
Panel Layout Drawings
Panel layout drawings translate the architect and engineer intent into a set of shop drawings that a site crew can follow. Each wall elevation is broken into numbered panels, with closing pieces at corners and openings, tie positions shown at the correct spacing, and a panel schedule that lists every unit by size and quantity. Openings for doors, windows and service penetrations are set out on the same sheet.
These drawings are the contract between the yard and the deck. When they are correct, the bundles arrive in the right order and the crew can set a floor without stopping to resolve a conflict. Chun Jet Formwork Engineering Company Limited issues layouts for review before fabrication, then keeps a controlled revision record so that a change on the drawings is never lost between the office and the site.
READY TO STRIKE
BUNDLE 4
Striking Sequence Planning
Striking is the most safety-critical part of the cycle. The striking sequence sets out the order in which wall forms, props, table forms and edge protection are removed, zone by zone, once the concrete has reached the required strength. It accounts for the way loads travel through the incomplete structure, so that no slab is asked to carry a load it cannot yet take.
Chun Jet Formwork Engineering Company Limited writes the sequence for each project and marks it on a zone plan that the supervisor and crew can follow. A clear sequence also shortens the cycle, because the release of one zone can begin while another is still being set, keeping the crane and the crew productive across the whole floor. Where the programme is tight, striking times are confirmed against concrete cube results or maturity readings before any prop is touched.
BUNDLE 5
Formwork Hire and Cycles
Formwork is an asset that should earn its keep on the building, not sit in a warehouse. Chun Jet Formwork Engineering Company Limited supplies wall panels, slab tables, props, walers, ties and accessories on a hire basis with agreed cycle intervals. The hire schedule is matched to the construction programme, so equipment arrives just before it is needed and returns as soon as a floor is complete.
Every dispatch and return is tracked, and wear items are inspected between cycles. Tie rods, pins and wedges are replaced on a planned interval rather than after a failure, which keeps the concrete faces consistent and the hardware safe. For developers running several towers, the hire model allows equipment to be shared between blocks in sequence, spreading the capital cost across the whole site and keeping utilisation high.
BUNDLE 6
Site Crew and Supervision
The best drawing set still needs people to execute it. Chun Jet Formwork Engineering Company Limited provides experienced aluminium formwork carpenters and a supervisor who reads the layout set fluently. The crew sets wall panels to the control lines, installs props, walers and ties, checks plumb and level, and keeps the working platforms and edge protection in place throughout the pour.
The supervisor coordinates with the main contractor, the crane team and the concrete gang so that setting, pouring and striking do not clash. By keeping the same crews on the same cycle, the company builds rhythm and familiarity: the crew learns the building, anticipates the next move and finishes each floor faster. That familiarity, more than any single tool, is what keeps a three-day floor cycle honest from the first lift to the top of the tower.
