Newman’s have started carrying out a detailed Concrete Survey to the tallest building in Watford Charter House.
The survey is expected to take between 7 and 10 days to complete and includes a detailed written report of all defects found and a full specification of repair, it is likely that the repairs will also be carried using Rope Access Technicians saving thousands of pounds on tube and clip scaffolding.
Newman’s are currently under taking a bed joint reinforcement scheme that we were asked to design and install in order to reinforce the masonry above the lintels at each level of this 6 storey mansion block.
The structural repair scheme was designed by our in house surveyors in order to allow the safe removal of the old load bearing timber windows and replaced with non load bearing uPVC windows.
In order to allow the safe removal of the windows 2 masonry beams will be installed resisting the tensile and compressive forces that will occur once the windows are removed.
Upon closer inspection of the masonry various areas of grout stabilisation and localised crack stitching will also be required.
We are currently carrying out a structural inspection and repair to a brick built railway bridge in North London.
Our client expressed concerns over the visible cracking and bowing present to the structure of which carries high speed trains into central London so it was vital that we acted quickly in order to carryout the inspection, design and implement a suitable structural repair scheme.
Bridge-reinforcement
To save time and cost in scaffold we opted to use our van mounted cherry picker that will enable our installation to be carried out rapidly, in less time that it would take to erect scaffolding.
The spandrel is suffering from de-lamination causing in some brickwork to fall from the masonry arch severely weakening the structure. the sofit which carries and distributes the loads of the masonry arch was showing signs of racking caused by vibration allowing water to penetrate into the structure causing defective pointing. the brick pier was also suffering from major cracking and separation.
We will be installing Twistfix helical beams at 300mm centres horizontally accross the masonry arch creating a grid pattern with the bars drilled 1.5m into the supporting pillars providing a reinforced structure distributing the loads. and over 4000 1.5m grout ties will be installed through the sofit into the arch pinning the sofit and preventing further delamination.
the works will be carried out so that the bridge remains fully functional and the road remains open and accessible.
