The six-story, 7,912 m²
(9,463 sq yd) “1 Stemple
Exchange” is complete and now
leased by U.S. company Guidewire
Software, and the identical “2 Stemple
Exchange” is under construction. In this
project, Peikko designed and supplied
DELTABEAM® for the client O’Reilly Precast,
working for the main contractor Bretland
Construction.
The architecturally impressive, mirrored
buildings were designed by TOT Architects,
and have a high profile on the N2/N3
link road, which divides the 40-hectare
corporate park.
Stemple Exchange’s structural design
uses precast square and circular columns,
with the DELTABEAM® Composite Beams
supporting prefabricated, prestressed, and
relatively lightweight hollow-core slabs.
Having DELTABEAM® spans as long as
12 meters (39 ft) reduced the number of
columns required by four per floor.
Both buildings have U.S. Green Building
Council LEED Gold certification (Leadership
in Energy and Environmental Design). Their
features include central cores that help to
maximize natural light in the office areas,
clean uninterrupted floor plates, spacious
2.8 m (9.2 ft) floor-to-ceiling height, 15 cm
(0.6 in) raised access floors with power,
double-glazed curtain walling, high-speed
lifts, and a total of 500 car parking spaces.
FLEXIBLE, OPEN FLOORSPACES
Liam Murphy, Regional Director at structural
engineer Doherty Finegan Kelly, says:
“On this project speed of construction
was essential, which is why we chose
DELTABEAM® over the originally designed
flat slab solution. We minimized onsite
wet trades using precast floor slabs with
DELTABEAM®, which in turn minimized
crane lifts, provided working platforms,
and eliminated the need for back propping
between floors. DELTABEAM® also gave us
large, extremely efficient floor plates and
removed the requirement for some internal
columns, greatly increasing flexibility in our
tenants’ open-plan offices.”
“We found Peikko to be thoroughly
professional and have been particularly
impressed by the level of detail in the
working drawings produced, which has
helped ensure the quality of the finished
building.”
According to Mike Scott, Peikko Sales
Manager DELTABEAM®, potential clients
are always impressed with DELTABEAM®
product’s fast, straightforward installation
and many features, capabilities and benefits
including long spans and integrated
fireproofing. Mike Scott says: “Stemple
Exchange is Peikko’s largest project in
Ireland to date, we’re getting very positive
feedback and it’s opening the door to
further projects.”
Seán Murphy, Development Manager at
Blanchardstown Corporate Park developer
Channor, says: “Peikko DELTABEAM® has
enabled us to achieve a flat slab soffit
(critical for ceiling void services) while using
the speed and efficiency of precast concrete
construction. The superior spans achievable
with DELTABEAM® have eliminated
mid-point internal columns, thereby giving
our tenants maximum flexibility with internal
fit-out design.”
PEIKKO EXPANDS IN IRELAND
In Ireland Peikko has been supplying the
precast and cast in-situ for several years.
In 2018 DELTABEAM® was used in the Four
Ferns Nursing Home project, working for
O’Reilly Concrete and main contractor
Purcell Construction.
“Everyone’s very happy with Stemple
Exchange,” says David Pike, Managing
Director for Peikko Ireland. “We’re now
speaking with more structural engineers
to get DELTABEAM® specified, and we’re
speaking with the precast manufacturers
and installers, and through them the main
contractors and clients. We highlight
major benefits such as efficient offsite
construction, faster installation using fewer
personnel, greater program certainty,
reduced need for concrete, and fewer site
vehicle movements.” ●
