Special requirements –
Works were carried out on night closures which had to be delivered within strict timescales. All works were closely coordinated with other trades to ensure that follow-on trades could install works within pre described night shift hours. Deliveries to site had to be managed to ensure the optimum utilisation of labour and plant, this resulted in the reliance of specialist supply chains to supply concrete. Standards of site cleanliness were strictly maintained as the carriageway needed to be clear and free of construction debris for the following day.
Weekend works had to be completed to tight timescales with 35-40 wagons loads of pre-cut concrete slabs loaded before 4 pm to ensure installation and curing of tarmac to be completed in sufficient time for the A19 to reopen on Monday mornings. Works were carried out over 8 weekends with 4 of the weekends witnessing excavation under interchange bridges requiring height restrictor on plant.
