Baltic View is a residential development sited within Liverpools Baltic Triangle area.The two Residential Blocks (10 & 8 Storey’s high) are designed around a landscaped central courtyard area.

Manchester Airport Multistorey Car Park –Galliford Try 

Llanfoist Waste Water Treatment Works is part of the Welsh Water investment under the AMP6 framework.Welsh Water needed to increase the capacity of the plant and appointed Skanska to upgrade the existing WwTW which includes sequential batch reactors/treatment tanksWestshield were appointed by Skanska to deliver the installation of the precast units and the construction of the wet concrete elements to provide the new sequencing batch reactor (SBR) structure.

The Technical Aspect:Pile cropping and pile cap constructionReinforced levelling padsInstallation of pre‐cast panelsReinforced slab construction and insitu wall stitches of the tankDeveloped a system to pour the full 7m height of wall stitches in one single pour, utilising self‐compacting concrete.Utilised Bamtec reinforcing bar system for the base slabs to allow the slab reinforcement to be delivered to site on a roll, which enabled quick and efficient installation, reducing safety hazards and reducing resource numbers.

Llanfoist Waste Water Treatment Works ‐Skanska

Skanska was appointed through the Welsh Water Alliance Framework to construct a new pumping station at Prioress Mill that would meet the requirements of the of the habitat directive and the fish & eel regulations on the existing site.

The Technical Aspect:The existing intake structure abstracts raw water directly from the River Usk and pumps forward to Llandegfedd Reservoir via a 60” pipeline approximately 4.6km in length. It was identified as a high risk asset with operational and maintenance issues based upon the reliability, age and safety of the installed M & E equipment.Constructability – The form of construction was a pre‐cast concrete wall and soffit units with continuity between each of the units provided in insitu cast reinforced concrete for both wall and slab interfaces.Foundations – Insitu cast concrete blinding and mass concrete levelling strips at various levels to found the precast concrete units forming the intake structure.Substructures – The scheme was built up over several levels, with the lower level basement forming the main intake part of the structure used for abstracting water from the River Usk. Intake structure included cells housing hi lift pumps that elevated the water to pipework supplying Llandegfedd Reservoir. Upper levels of the structure house the main body of the mechanical and electrical equipment.Temporary works – Significant temporary works designs have been undertaken in‐house and were issued to the principal contractor for all the planned insitu concrete works.Environmental – Due to a large amount of insitu concrete used the pH levels of the River Usk were constantly monitored. Water from the basement levels during the construction phase was passed through specialist equipment to assist with control of the pH prior to discharge of this water into the river.

This £30m residential development consisted of 18‐storey and 14‐storey blocks with three levels of underground car parking. Stair/lift cores in each block were slip formed with precast stairs in each. The substructure is a traditional reinforced concrete frame 

with post tensioned slabs within the superstructure.
