Now nearing its completion, Howard Civil Engineering are pleased to be supporting Wates Group in the delivery of the groundworks and RC Frame packages on this prestigious site.
The footprint, existing topography and city centre location made this a challenging build which was off set by the advance logistical planning undertaken by Howard Civil Engineering prior to being awarded the scheme.
The works commenced in July 2017 with the groundworks package.
In brief the substructure consists of a 3500m2 basement with foundations, drainage, retaining walls, earthworks and vertical columns and cores.
The superstructure involves the construction of 6no blocks up to 8 stories high.
It will take approximately 45 weeks from groundbreaking to casting the final roof upstand.
• Substructures element including mass fill, reinforced bases and ground beams.
• Drainage including a bespoke cellular attenuation tank designed to utilise the void behind the retaining wall thus reducing additional dig and backfill
• External services
• Waterproof fibre reinforced ground floor construction with separate tanking membrane
• Waterproof RC Retaining wall integral to the building to manage variation in levels onsite
• Post tensioning floor construction from level 2/3
• Superstructure RC frame varying in heights from 6 to 8 stories
• Constrained City Centre site
The utilisation of a ‘Twinwall’ construction methodology for all vertical works enabled us to support Wates’ ambitious delivery programme.
Advantage was taken of the rock arising from the basement excavation. Processing the arisings to produce granular fill to backfill all retaining walls reduced haulage movements across the city in disposal and imported fill.
The resource level peaked at over 100 emplyees with a delivery team of 11 non-working people.
Due to its prominent city centre location, topography and size, site constraints were challenging but overcome by a detailed delivery plan and sequence, the use of offsite construction methods and utilising our local plant yard to co-ordinate deliveries and make up falsework/formwork.
