The document discusses the Shard building project in London. It describes the Shard as the tallest building in Western Europe at 310 meters tall. BASF provided admixtures to help with a record-breaking concrete pour of 15,000 cubic meters for the basement levels. Their product MasterGlenium SKY 569 accelerated curing to allow for fast-track construction, meeting the goals of quality finish and on-schedule completion. The concrete pour was completed ahead of schedule, placing over 5,000 cubic meters in under 36 hours.

The cement industry is worldwide one of the main contributors to man-made CO2 emissions, estimated at 7% of global emissions.
To keep pace with the demand and pressure to reduce CO2 emissions, a shift to sustainable building materials for housing and infrastructure must still be continued.
Cement manufacturers can make significant progress toward sustainability goals with alternative fuels and efficiency projects by reducing clinker content through cementitious additives (SCM).

Why don't all GCs include drywall in the BIM execution plan? What happens when they do? What happens when they don't?
This presentation provides an overview of Marek Brothers' process to create a more accurate architectural model by providing an exact representation of the physical and functional properties of both walls & ceilings. Paul Godwin, BIM Manager at Marek Brothers, will provide a summary on how they utilize this process to create virtual mock-ups, manage geospatial coordination and maximize prefabrication construction practices. It will give case studies of the effectiveness of being involved in the coordination process as well as projects that declined BIM services and the consequences.

The Shard, London
The background
The Shard is a futuristic, inspirational mixed-
use urban village concept tower designed by
architect Renzo Piano. Adjacent to London‘s
busiest strategic transport hub at London
Bridge, the Shard is the tallest building in
Western Europe, standing at 310 metres.
The structure’s core was slip-formed in
reinforced concrete and progressed at an
impressive rate of three metres a day whilst
the basement levels were built top down
simultaneously.

The Shard
BASF assists record-breaking concrete pour
The challenge
Key requirements needed for the concrete on
this project were quality of finish and speed of
curing to support fast-track working without
sacrificing other performance properties.
A massive continuous concrete pour was
planned as part of the construction of the
three-floor basement box, which had a depth
of 13.3 metres and required a total volume of
concrete of 15,000m³.

BASF assists record-breaking concrete pour
Image Description
Our solution
Our experts from BASF Construction Chemicals worked with
technical consultant OTB Engineering to supply admixtures for
the concrete being used in the structure’s core and basement
levels to ensure consistent strength, quality and speed of cure.
This resulted in the development of a new product,
MasterGlenium SKY 569, with The Shard project in mind.
MasterGlenium SKY 569 is based on BASF’s Total
Performance Control concept, developed to ensure that ready-
mix producers, contractors and engineers achieve a concrete
that is of the same high quality as originally specified, starting
from production at the batching plant, to delivery and
application into place, followed by the hardening process.
Utilising Rheodynamic concrete technology, it provides a
concrete mix with exceptional placing characteristics and
accelerated cement hydration for early strength development
and high-quality concrete.
Benefits to the customer
Quality of finish.
Speed of curing to support fast-track working.
Projects facts at a glance
The record-breaking concrete pour for the basement’s
construction, the largest UK continuous concrete pour to
date, started at 5 pm on Friday 16th April 2010 and went on
until 4 am on Sunday 18th April.
The programmed time had been 36 hours for 5,000 m³ of
concrete, using four concrete pumps.
The actual placement time for 5480 m³ was 35 hours,
beating the schedule both on time and volume.
The total volume of BASF admixtures used in the pour was
11,000 litres of MasterGlenium SKY 569 and 5,000 liters of
MasterSet RT 100.
Previously, the UK’s largest continuous concrete pour from
a ready mix supplier was 4,800 m³ (at the new Wembley
Stadium).
