CLM were appointed as the Principal Contractor and supplied the welfare facilities and Preliminary items required to undertake the complete works. The works commenced with the erection of a large temporary scaffold roof covers and access decking with safety crash decks and safety nets, which were directly installed and managed by Clear Line operatives. These scaffold and safety net measures enabled the safe removal of 11 Patent glazed steel structures from above the “live” shopping centre at Queensgate where the public continues to shop directly below. The old roof light materials were safely removed and responsibly disposed of, including asbestos.
The new roof lights were designed and procured by Clear Line . They consisted of new steel supporting framework which supported a new aluminium curtain walling frame (Schuco FW50+) via purpose designed brackets. Within the framework and glazed into position were new double glazed glass units, composite knuckle corner panels, powered glass & weather vents and various folded sheets and pressed metal components, skirting’s/cills & EPDM. There were bespoke gutters, condensation channels and cable conduits installed to complete the works. The project spanned a total of 1044m².
The vents are connected to the centres Building Maintenance System, meeting specific air volume flow rates & operational requirements requested during the tender process. Special smoke sensing detectors are installed within the rooflights and are additionally connected to the Building Maintenance System.
All of the above was carried out under the watchful eye of NET Project Management who were the façade consultant on the project.
Phase 1 was completed in February 2013 (6 roof lights) and phase 2 (5 roof lights) is expected to complete around August 2013.
Southmead Hospital Redevelopment Project has received £430m worth of funding. It incorporates the largest fire screens in the UK at around 5000m² and up to five stories high.
Clear Line were appointed to design, supply and install the fire rated steel curtain walling, fire rated glass, balcony balustrades and fire rated roller curtains. We worked closely with expert collaborators to provide this package on time and to budget.
The architects desired contemporary look was achieved with a variety of coloured glass panels built into the façade. The colours used were selected from a vast range of sample panels and along with all other materials included in the detailed purchase order schedule for delivery to site on a just in time basis. Thus avoiding unnecessary storage space and reduce the risk of site damage.
The management of the project was undertaken on several levels. Head Office Design and Procurement and on site Project and Installation Management. These activities were all overseen by a Clear Line Director to ensure the project was completed on time and on budget
Clear Line have been appointed by our Client to increase the thermal performance of the window system and add a cladding system to upgrade the old building aesthetics to match the new build element of the complex.
We have worked closely with the Client and suppliers to design bespoke cill pressings and a purpose made aluminium bead. These will be paired with new double glazed units to achieve an overall U value of 1.1 ultimately increasing the thermal performance of the window systems.
Trespa panels will be supplied and fixed onto the concrete using ‘Z’ angles and bolts. This will then upgrade the original building to meet the visual aspects of the new building on the complex.
Health and Safety has been critical on this project due to the community college being occupied throughout the duration of the works. All operatives on site are required to have a full CRB check in place before commencing on site. Special provisions have been necessary for delivery of materials, as the only access to site is directly through the yard of the new build community college.
Clear Line worked with our Client to install a new flat roof to the upper turbine hall at Sizewell Nuclear Power Plant.
An IKO roofing product was chosen to replace the existing felt material which had failed and was allowing rainwater and other such ingress to all parts of the upper turbine hall roof deck, parapets, gutter and supporting superstructure.
The Health and Safety requirement was of paramount importance to our Client. We are Achilles UVDB accredited which gave the Client the reassurance that we have the highest health and safety and quality systems. All operatives on site were security checked by undergoing the rigorous Disclosure Scotland Procedure.
Endcliffe Student Village was built under a PFI initiative for Sheffield University by a Main Contractor. Our Client have the contract for maintaining and repairing any damage. The village is always occupied by students during term time and strict rules have to be adhered to when on site. The buildings we work on are technically complex with special thermal rated glass and high-quality curtain wall panels.
Under the terms of their contract Lend Lease have strict standards of service to maintain. Depending on the seriousness of any damage they must repair within 4 hours, 10 hours or 10 days. Clear Line can be called out to any element of the building including windows, doors, roofs, gutters and façade failures.
The Client required a specialist supplier who understood the technical element of the work and who was reliable in being able to turn a job around within the deadline. Clear Line set up a supply chain and a planning and scheduling system to ensure we hit the target dates.
We are also involved in some planned maintenance works that are completed onsite such as roof remedials and gutter repairs. These planned maintenance works take place during the summer months when the buildings are not occupied.
Clear Line were appointed to complete the replacement of four glass units which make up part of the unitised façade.
We removed the failed glazing components and installed new structurally bonded units on four different levels of the north and south elevations. The supply of the units proved quite difficult as the previous supplier was outside the EU and were not contactable, therefore Clear Line was required to find the best match possible to existing materials.
The replacement units were pressure fixed, utilising an internal and external pressure plate and tourniquet system to the structural silicone which required 21 days to cure. A return visit was then made to ensure the units were fully bonded and to remove the internal and external pressure fixings.
As the replacements being completed were high rise we used the insitu BMU cradle and auxiliary hoist. A four in line woods vacuum lifter was used to manoeuvre the pieces of glass into place along with the hoist.
All operatives working on site were trained for working at heights and all received full BMU and hoist training.
