The proposed works at Park Spring Primary School will increase its capacity from a 1.5 form to a 2 form entry with effect from 2018. The two storey extension links to the existing building on both levels allowing free flow movement between old and new.
The structural solution was determined as steel frame construction on mass concrete pad foundations. Lateral stability was catered for by a combination of vertical cross flat bracing and portal bracing. The roof construction is insulated structural decking supported on the hot rolled rafters which in turn are supported on the steel frame.
The works also include an element of internal remodelling and refurbishment within the existing school building together with some off-site highways works in connection with the new development.
The building works comprise the installation of 3 double modular classrooms as decant space whilst a single storey classroom block is demolished to make way for the construction of a new 2 storey classroom block extension, linked at both floors to the main school building. The extension provides two storeys of teaching accommodation linked at both levels to the main school building which will include 7 classrooms with associated toilet, cloakroom, storage facilities, a dedicated ICT Suite and administration accommodation.
Extensive landscape works and highway alterations have been incorporated into the scheme to improve access and safety within the school. A new access point into the school will allow cars, pedestrians, cyclists and emergency vehicles into the site from Swinnow Lane and provide access to a staff and visitor car park.
On completion of the new 2 storey classroom block the temporary classrooms will be taken away and the landscape works finalised.
3D phasing models
BIM modelling was used to ensure a tight construction programme progressed despite insufficient time to procure steelwork to allow the usual construction sequence. Construction phasing models were used in a collaborative environment with the Architect to produce drawings for the contractor. This allowed the foundations, retaining wall and ground slabs to be accurately programmed and constructed by the contractor early. Overcoming this logistical challenge saved valuable time and enabled the steelwork to be constructed out of sequence with the normal construction timeline.
The existing site was also very constrained and so Adept worked closely with the contractor to ensure careful coordination of the sub-structure to allow for crane movements.
