Product | Tac Systemformwork vs Conventional Technology
Traditionally, timber and plywood are used for formwork fabrication for the construction of concrete structures. It is still the most widely used medium as it is the most versatile since they can form the most intricate shapes and forms of the structures. However, it needs many skilled and unskilled workers besides being very time consuming. In today’s competitive market, speed and efficiency is of primary importance.
In view of this, many various construction systems have been introduced over the years such as the “Tunnel” formwork system, the “Grace” formworks system and the “Table” formwork used by various parties. However, all these systems are not “complete” systems in that they are able to form only parts of the building structures such as the wall or lift core, etc.
The TAC System was introduced into the market about ten (10) years ago and has been successful in gaining market acceptance from the local and overseas construction industry. Among the key success factors of this system are:-
The system allows 100% of the building superstructure to be constructed or formed at the rate of 4 days per floor as against the traditional approach which will take at least 10 to 15 days a floor. Even then, the latter can only do for columns, beams and slabs only and the infill walls have to be built and plastered later.
The flat, off-the-form finish produced by the TAC System simply requires a 2-3mm skim coat before decoration, thus eliminating the need for plastering. In addition, all the elements of the building are accurately dimensioned and are vertical, horizontal and square in plan and section as intended, so that remedial works to correct inaccuracies are eliminated.As service collars can be accurately located and cast-in as the slab concrete is being poured, leaks are eliminated. This is a major hidden saving, as builders are very reluctant to admit the true costs of locating and remedying leaks – these costs get swept into the “contingency” figure. In addition, the bad publicity that a “leaky building” attracts has a very damaging effect on a Developer’s reputation.
The system provides an inherent safety features in the use of props which need not be removed to release the slab forms. Overlooking of re-propping in one of the commonest causes of fatal accidents on building sites.
- Independence from Scarcity of Skilled Tradesmen
The TAC System eliminates the need for skilled plasterers as noted above, but it also eliminates the need for skilled carpenters and brick layers. Projects have often been seriously delayed because of the unavailability of these skilled trades.
The need to carry the cost of scaffolding for the construction of the structure is eliminated, as the TAC System provides its own work platform brackets, which ascend the building as it being constructed. There is the added advantage that the infrastructure can now proceed in parallel with the building construction, as the contractor has unimpeded access to the base of the building.
The crane is not required for the movement of the forms up the building as the construction proceeds. Thus the crane is available for concrete and steel placing and other materials movement. The crane is only required for moving the forms down from the top of the completed building.
The TAC System allows consideration of a “load bearing walls” structural design approach. A LBW design will always be more structurally efficient than a traditional “reinforced concrete frame” approach and will give a very much stronger building. It will therefore be less expensive to construct and to provide foundations for.Because the TAC System is modular, it can be fitted to any architectural or structural layout. Thus, the designers can be as creative as they like and yet be confident that advantage can be taken of the system approach to construction. In this regard, the TAC System is quite different to Tunnel Forming or systems based on the use of Flying Forms – both of which require the designers to modify the design the building to suit their particular system.
Not only does the TAC System give a remarkable construction speed, it gives the speed reliably. We will contractually undertake to complete 6 floors per month (i.e. 6 floors at 4 days per floor, plus approx 6 days to spare for items outside control e.g. crane breakdown, access problems, access for ready mix trucks, etc. etc.) and would be confident of exceeding that rate. This allows the Developer to plan accurately and with confidence and streamline his own organization for handover of apartments or commercial space to Clients.
- Overall Financial Advantage
When all of the above are taken into consideration over the construction period of a suitable project (i.e. one where there are more than about 50 repeats of a typical layout), the overall profit to the Developer can be increased by a factor of from 10 to 30%. The overall advantage is the cost and time savings to the developer.
In view of the above, TAC System Formwork Sdn Bhd has a very competitive state-of-the-art technology which has gained market acceptance over a relatively short period of time as evidenced from the major projects completed and new projects secured to-date. Some of the TAC System’s clients are established and reputable developers and contractors themselves such as C.A. Goh (Green Lane Park Penang and University Place Penang), Sunway City Berhad and Putra Perdana Berhad which lend much credence to the TAC System Formwork. The fact that the TAC System has made inroads in the highly competitive and advanced countries such as Taiwan and Hong Kong within such a relatively short time is sufficient of TAC’s superior formwork technology.
With the revival in the local construction industry, in particular that of low and low-medium cost houses, as well as massive demand for speedy social housing development in the countries in the Asian region and other parts of the world, TAC System Formwork Sdn Bhd foresees a tremendous growth potential in its business over the medium term. TAC System Formwork Sdn Bhd’s strategy of market penetration to overseas will also mitigate any possible major downturn in the local construction industry.
