If you haveactually been a routine guest takingatrip through Bristol Temple Meads station any time in the past years, you will haveactually seen the transformational advancements taking location in and around the station.
To the west of the station, on what was when an uninspiring landscape of scrubland, carparks and deserted brownfield websites, a cluster of glossy glazed domestic and industrial structures increase above the city’s historical Floating Harbour.
With a bit of a squint (the structures aren’t rather of the exactsame scale) it now does a satisfactory impression of London’s Canary Wharf.
This is all part of a strategy to redevelop the location under the ‘Temple Quarter’ banner, a large varying plan that is set to change more than 130 hectares of brownfield land over the next 25 years. The task guarantees to provide 10,000 brand-new homes, workplaces, researchstudy and industrial area, enhancing Bristol’s economy and producing 22,000 brand-new tasks.
But perhaps it is to the east of the station where most of the regrowth is taking location. A derelict previous postal sorting workplace that loomed big over the station and drewin a high level of antisocial behaviour hasactually been destroyed and the broader website cleared.

This the part of Temple Quarter that is allocated for the Enterprise Campus – an enthusiastic strategy from the University of Bristol to offer a brand-new researchstudy, advancement and knowing center focusing on digital, organization and social development as well as brand-new lodging structures for the trainees.
The school is created to be car-free, which undoubtedly suggests more individuals will showup by train at the neighbouring Temple Meads station.
In anticipation of the rise in traveler numbers, Network Rail is now embarking on a plan to increase traveler centers, offer brand-new retail systems, enhance the public world and revamp, repairwork and enhance the existing station centers to supply mucheasier gainaccessto from public transportation, walking and biking paths. And secret to this advancement is the building of a brand-new Eastern Entrance to the station.
Network Rail figures recommend that within 4 years of its opening, an approximated 2.5 million individuals will usage the brand-new Eastern Entrance, which is now being developed under a £25m ‘target expense’ agreement granted to primary professional Bam Nuttall.
The entryway itself is being built underneath the line that serves platform 15 at Temple Meads and will break through into the existing underground train that supplies gainaccessto to all platforms for travelers from the primary station concourse to the west.
It is an uncomfortable website: a wedge of land sandwiched inbetween the strengthened concrete frames of the emerging school structures and the 3.5m-high brick-built keeping wall that supports the track bed and keeps platform 15’s embankment from slipping away.
But it is not simply the website itself that has tested uncomfortable. As is the case with most train jobs, the preparation and logistical work that hasactually gone into the arrangement of the brand-new entryway hasactually been long and complex.

“The Eastern Entrance task is being brought out in 2 stages,” describes Alex Phillips, lead portfolio supervisor at Network Rail. “Phase 1 was brought out in July and August 2021, when there was a blockade of the station under the Bristol East Junction enhancement work.”
Carrying out the Phase 1 work throughout the Bristol East Junction blockade – a significant plan that has assisted minimize a trafficjam and enhance signalling into the station – permitted the Bam Nuttall group (which began initial work on website in October 2020) to lift the track above the proposed entryway and bring out the civils work below the track bed.
“We took benefit of the blockade to setup the 2 adjoining stacked walls that kind the train entryway and the sacrificial sheet stack wall that was part of the short-term works. This avoided any motion of the track bed as work advanced,” describes Glyn Cryer, senior job supervisor at Bam Nuttall.
The sacrificial sheet stack wall momentary works were formed of 27 GU28N sheets driven 12m through the 6m-deep layer of made ground and into the alluvial deposits below. Any motion of the existing structure as building work advanced was carefully kepttrackof.
In all, 45 of the 600mm-diameter continuous-flight auger (CFA) stacks were setup to depths of 14m to produce the 2 adjoining stack walls. These assistance the 7 12m-long, 1.8m-wide and 550mm-thick precast concrete slabs that were raised into position to kind the roofingsystem of the extended belowground guest concourse below platform15 Excavation of the train was left upuntil Phase 2 of the agreement.

Work under the 2nd stage started on website in October 2023 with subcontractor Penny Demolition saw-cutting through the existing brick maintaining wall so that that the group might tunnel underneath the track and break through to the existing guest train. In all some 750 tonnes of product hasactually been excavated to develop the brand-new 10m-wide, 12m-long area of train.
The brand-new entryway functions a 20m x 10m x 5m steel-framed and glazed structure that will home ticketing centers and traveler gate as well as a personnel control space and brand-new power boxes.
Thanks to the depth of the bad made ground and alluvial deposits, it is established on an variety of 15m-deep, 450mm-diameter sectional-flight auger (SFA) stacks. There are 17 in overall with a 1m-wide, 750mm-deep topping beam. Concrete for the stacking work and the topping beam is a lowered carbon ‘Ecocrete’ mix provided by Heidelberg.
There are 8 primary roofingsystem girders which that period the 20m throughout the structure and are just supported with columns. Each girder was brought to website in 3 areas and repaired into position.
The steel frame façade functions glazed systems. Those on the roofingsystem weigh in at 400kg each and there are 6 inbetween each girder. They were raised into position utilizing a mobile crane with all work brought out under Network Rail’s strict ‘all line running’ working conditions – where every element of plant and product motion togetherwith the train is evaluated to remove any possible effect on those rail lines open to traffic.
“The steel beams were simply too long to ge
