a.b.e. is part of the Chryso Southern
Africa Group. Ivor Boddington, a.b.e.'s
Product Manager: Concrete Repairs
& Protection & General Construction, says
Autodesk REVIT is an innovative building
information computer program that has trans-
formed building design from drawing flat
sketches on paper to creating virtual, three
dimensional designs.
"It enables architects; structural engineers;
mechanical, electrical and plumbing (MEP)
engineers, designers and contractors to design a
building and its components in three dimension,
annotate the model with 2D drafting elements
– such as used for waterproofing – and then
access construction information from the
building model's database," Boddington stated.
"Three-dimensional modelling itself is not
new but in the past the 3Dmodels would merely
illustrate what a building would look like when
completed. Now, thanks to the Autodesk REVIT
program, architects and other parties involved
in designing and construction can plan ahead
when it comes to the finer details of their design,
including the annotation of the a.b.e. water-
proofing the new structure will require.
"The fact that a.b.e. waterproofing specifi-
cations can now be extracted and inserted to
a project at the design stage means that the
designers can automatically generate a Bill
of Quantities containing all the products and
measurements required, the extruded elevations
to be provided for, as well as the final conceptual
visualisation," Boddington explained.
Autodesk REVIT enables designers to extract
energy analyses and environmental impacts, as
well as waterproofing requirements, prior to
the construction of a building, thereby saving
important additional unforeseen costs later in
the construction schedule.
Boddington added that is planning
to preload all other applicable a.b.e. products
onto Autodesk REVIT software, including a.b.e.'s
flooring, specialised adhesives, structural glazing,
concrete repair, silicone and sealants, and
construction commodity products.
Umesh Chhika, general manager for Asia
Pacific and strategic projects at BME,
said the company has been engaged
to provide electronic detonation systems and
related technical advice to ensure low-vibration
blasting in the 35 metre-deep box cut, from
which three more rail tunnels will be developed.
He said the special requirements of the
project suited BME’s specialised expertise in
electronic detonation services and products.
“We havemade huge strides in advancing the
field of controlled blasting through our digital
blasting systems,” said Chhika. “Electronic delay
detonators play a vital role in controlled blasting,
especially when used in conjunction with our
in-house AXXIS digital initiation system and
supporting software.”
The timing flexibility of the AXXIS system
supports the detonation of small, multiple
charges in each blasthole to keep vibration levels
down, he said, and the accuracy of the timing
between individual charges allows vibrations to
be predicted accurately and reliably.
The TEL project is a 43 km underground rail
line between the existing Thomson and Eastern
Region commuter lines in Singapore, and will
add 31 new stations to the existing rail network.
The first phase of the facility is expected to start
operating in 2019.
“To further enhance our controlled blasting
techniques, BME employs its own Blast-
MapIII software to plan complex timing
designs and also analyse the results for each
blast,” said Chhika. “Our extensive experience
– which earned us this contract –
includes blasting for various civil
blasting contracts.”
BME’s advisory services will there-
fore augment the company’s products
and software to ensure the success of
their contribution.
WATERPROOFING LOADING ON REVIT
South African architects and other designers have welcomed the
fact that the specifications for a.b.e. Construction Chemicals'
waterproofing products have now been preloaded on Autodesk
REVIT software.
a.b.e.'s full range of waterproofing products
are now within easy access for architects and
designers through Autodesk REVIT software.

REDUCING BLAST VIBRATIONS
SA-based blasting leader BME is supplying advanced detonators
and expertise to Rock Busters PTE, a blasting specialist
subcontractor to Samsung for the construction of Land Transport
Authority (Singapore) Caldecott Station, T213 Thomson-East
Coast Line (TEL T213) to blast with the least possible vibration
impact – protecting nearby tunnels, skyscrapers and other
sensitive structures on the land constrained city-state.
