Designing and constructing a DM1 floor slab to tolerance

Constructing the DM1 floor slab in Qatar to a tolerance of 99.4%
Designing and constructing a DM1 floor slab to tolerance, whilst maintaining all the advantages of a large panel 'jointless'SFRC floor slab is no easy feat.
Even with so called expert supervision, constructing a floor slab on this scale remains challenging for any specialist flooring contractor. Often the end result generally requires substantial remedial grinding within the aisles to meet MHE operational standards.
Why is this the case?
To reach exacting tolerances, every part of the construction process must be perfect before the process moves to the next stage. An imperfection early on will be amplified as construction continues. Mistakes made early on are not easily resolved and the implications can be far reaching, from delays in delivery to over budget contracts and quality issues later in the floors life. With split responsibility and outsourced processes, high tolerances are frought with problems and are almost impossible to achieve.
How do you achieve DM1 flatness and high tolerances?
The short answer is, through a combination of success factors.
- Highly skilled and experienced workers, directly employed and quality motivated
- Dedicated flatness team working alongside experienced finishers
- Precision in-house developed machinery and maintenance
- Strictly controlled & prepared working environment
- Concrete mix design, delivery and quality
- Robust quality control processes
By carefully controlling every step of the process with the precision not normally seen in concrete flooring construction it is possible to achieve a 99.4% compliance, as Twintec demonstrated at a new logistics facility in Qatar.
There can be no margin for error and by taking total responsibility for all elements of the process, strict margins can be achieved. At Twintec we call this 'Design . Build . Guarantee', a service that removes any split responsibility for the floor slab.
We have a long standing track record of designing and constructing high tolerance floor slabs worldwide as verified by independent consultants:
------------------------------------------------------------------------------------------------------------------------
"The floor laid by Twintec for Al Madina in Barka Oman was the flattest we have ever surveyed. I congratulate all the men involved for the very high standard of flatness achieved" Floor Surveys Limited.
"Monofloor Technology surveyed the floor for BMW immediately upon completion and found an exceptionally high level of compliance for a CSTR34;2003 Category 1, defined movement floor constructed using large pour techniques. No grinding was necessary and the floor was very well finished" Monofloor Technology Limited.
