The GOSH Deconstruction and Construction Management Plan sets out a lot of changes they want to make to our streets, trees and parking. It also indicate the number of lorries we can expect each day for five years.
Here's a selection from their document.
Expected Construction Traffic (page 33)
It is expected that existing surrounding highways will experience an increase to heavy goods vehicles during the deconstruction and construction period.
Based on the current proposed design Sisk has carried out calculations to identify anticipated vehicular needs, these consist of:
▪ demolition: general quantities – 3,000m3 3 wagons per hour @ 8m3/wagon = 375 wagons ▪ general rate - 15wagons/day (removing120m3);-
▪ substructure: General quantities - Excavation 17,640m3 ▪ general rate - 30wagons/day;-
▪ superstructure - general quantities - 108m3 concrete per week = 22trucks, +5 rebar, +2 formwork ▪ general rate – peak concrete on a pour day = 30wagons: 720 muck away vehicles over a 20wk period;-
▪ envelope - general quantities – weekly delivery, 2 glazing, 2 SFS, 10 precast; and-
▪ fitout - weekly delivery, 4 M&E, 4 plasterboard, 2 joinery, 4 others.
Parking Bay Suspension and Temporary Traffic Orders TTO (page 38)
To facilitate safe continuous public travel throughout the construction phase temporary highway alterations are required, these include the following:
▪ Guilford Place & Great Ormond Street two-way traffic to be amended to one-way traffic traveling east – west throughout the entirety of the construction phase; and-
▪ suspension of existing parking throughout construction period.
▪ Guilford Street;-
▪ suspension of existing zebra crossing; and-
▪ potential relocation / conversion of existing pedestrian crossing into zebra crossing.
▪ Guilford Place:-
▪ partial suspension of loading (double yellow lines) at the southern end.
▪ Great Ormond Street:-
▪ suspension 1 disabled parking space;
▪ suspension of 13 Resident permit holders parking;
▪ suspension of 4 single yellow line loading and unloading spaces;
▪ Suspension of 1 location of double yellow highway provision;
▪ suspension of 12 pay and display parking; and
▪ suspension of 5 ambulance drop off locations.
▪ Boswell street:-
▪ suspension of all single yellow line loading and unloading spaces;
▪ suspension of 10 resident permit holders parking; and-
▪ suspension of 4 pay and display parking.
Occupation of Public Highway (page 42)
During the construction phase our hoarding line will encompass the entire northern pedestrian footpath and half of the existing Great Ormond Street.
To enable construction traffic to travel within the redline boundary the following alterations to the existing realm are required:
▪ removal of 14 existing trees on Great Ormond Street pedestrian walkway;
▪ removal of 19 existing bicycle hoops: 11 belonging to GOSH and 8 belonging to Camden Council;
▪ removal of 3 street corner vehicle bollards;
▪ removal of 1 public telephone box;
▪ removal of 2 public general waste bins;
▪ removal of 3 street light lamp posts;
▪ removal of 3 street signposts; and
▪ removal of 2 public seating benches.
To enable construction traffic to safely navigate outside the hoarding boundary the following enabling works has been currently identified as required:
▪ pruning to 4 London plane trees on northern junction on Guilford Place;
▪ adjustment to existing southern pedestrian footpath and curb line on Guildford Street; and
▪ relocation of existing pedestrian crossing on Guildford Street.
To permit construction activities the removal of 10 existing Category C trees is to be undertaken. Our completed arboriculture assessment concludes these specific trees are immature specimens of limited landscape value.
To permit proposed construction site welfare, accommodation and site access the removal of 4 existing False Locust trees is required. The individual trees have been noted as Category B with an estimated remaining life expectancy of at least 20years.
It is however noted that all False Locust trees are of a species which is identified as invasive within the London Invasive Species Initiative, as such it is not considered that its loss should be seen as a significant constraint to development.
There are 4 mature London Plane trees on the corner of Guildford Place.
Preconstruction analysis has identified a potential risk of construction vehicles clashing with existing overhanging branches. It is proposed that required pruning to existing trees is carried out to prevent damage during construction.
