2009 2010 2
As one might expect, thegroundworks and foundationsto Europe’s tallest building are
considerable and complex. Top-down construction was used sothat work could start on the corebefore the lower basement levelswere constructed.
To achieve this, secant pileswere first installed around theperimeter, and bearing pileswithin the basement footprint. Acapping beam was then cast tolink together the secant piles, andthe ground-floor slab was cast,leaving an opening for the core.
e slab was supported onthe capping beam and plunge
columns. In the centre these hadto be positioned very accurately,between piles left over from theprevious building, in order toprovide a stable base from whichthe core could be launched.
e basement was thenexcavated to level B2, and thecore slipform launched from this
level. Next, the B2 slab was cast,supported on the secant wall,plunge columns and the core, and
the ground floor central openingwas infilled.Excavation then continued to
level B3 and the B3 (foundationraft) slab was cast. Core wallswere completed from B3 to B2.Finally, the B1 slab was cast.
Despite its size (up to 6m deepand never less than 1.5m), thefoundation slab was cast in onepour. “We didn’t have to do it inone go,” says Houston. “But a keyfactor was that there was so muchreinforcement, we would have hadto put a stop in through seven
layers of steel at the bottom andfive at the top. Heat gain was alsoan issue, but by adjusting the mixthroughout the pour we kept thisto a minimum.”
Some 5,500m3, or 700truckloads, of concrete werepoured over 36 hours – the largestpour London has ever seen.

building review | park hill, SheFField
return of the
high streetPark Hill’s ‘streets in the sky’ were once notorious, but the Shefeld estatehas now been sensitively restored – adding colour, natural light and a senseo openness, while maintaining the integrity o its imposing structure
Te frst reurbished homes o Park Hill, the
brutalist residential development that dominates
the Shefeld skyline, are now on sale. Built
in 1957 by Jack Lynn and Ivor Smith working
with JL Womersley o Shefeld Corporation City
Architects Department, Park Hill is architectural
marmite. It was the most ambitious inner-city
housing development o its time and at frst proved
to be very popular. However, rom the 1980s a lacko investment and rapid social change contributed
to its decline and it began to epitomise all the
supposed ills o mass housing design. Now though,
its regeneration has capitalised on the intelligence
o the original design to successully meet the
aspirations o a new generation.
Built on a steeply sloping site with a gradient
o 1:10, Park Hill has a commanding presence
over the city. Te building profle engages with
the topography o the site, with the roo level
remaining constant as the height o the residential
block ranges rom our to 13 storeys. Te building
pioneered modern design and building techniques
including the “streets in the sky” which aimed to
recreate the community spirit o traditional streets
within a high-rise development. In recognition o
its historic signifcance, Park Hill was granted grade
II*-listed status in 1998, making it the largest listed
structure in Europe.
A wide-ranging collaboration between developer
Urban Splash, Shefeld City Council, GreatPlaces Housing Group, English Heritage and the
Homes and Communities Agency, together with
architects Hawkins\Brown and Studio Egret
West and landscape architect Grant Associates,
is undertaking a £160m regeneration scheme to
turn Park Hill into a vibrant place to live or the
21st century. When completed, there will be 874
apartments, one-third o which will be aordable
housing, as well as new retail and leisure acilities.
Te concrete structural grid o the blocks was
