Optera praised for our approach to health and safety and property protection

OpteraOptera were recently instructed to complete works to take down and replace a retaining wall within a rear garden of a property in South East London. With no external access to the rear, Optera set about designing temporary protections to the house to minimise the impact of conveying spoil through the house. The skilled tradesmen, set about boarding the floors and walls to protect them from knocks and debris from plant and materials transferred through the property. In addition, PPE and a site file detailing the risk assessments and other site specific details are located at the point of site entry along with the site register. The policyholder had expressed concerns about the scale of the project and the potential impact this would have on his property during the course of the works. He needn’t have worried as Optera are used to working in difficult access and problem sites and took the matter in our stride. Due to the terracing of the garden, it was necessary to employ the use of specialist spoil shoots to transfer the rubble from the upper garden, down to the lower level and through the house to the skip at the front.
Welfare facilities were located at the front of the Property and the entire site protected with herras fencing and signs warning the wider public of the dangers of this live site. Our client was so impressed That they have requested pictures to use for future Training and Optera were thanked for their Conscientious approach to health and safety. Whilst Optera have a reputation for innovation and cost saving repairs, we always take the fundamental responsibilities for the safety of our staff and other stakeholders affected by our works very seriously.

Optera raise the roof in Bromley

Optera were recently approached to undertake structural lifting on a double garage in Bromley. Constructed on a raft foundation, the underlying strata was brick rubble over soft alluvial fill to approximately 4m below ground level. The garage had progressively distorted about the left hand side and large cracks had developed across the rear elevation and a crack developed across the floor.
Our engineers assessed the scheme and elected to drive 5 steel cased piles around the left hand side and rear of the garage with r.c pads formed under the existing raft. Using our specialist lifting equipment, we raised the garage a maximum of 70mm about the rear left hand corner, closing the cracks from a maximum 40mm to the original 10mm joints. Additionally, the distortions across the floor slab were all but removed and the crack, cut out, dowelled and reformed in reinforced concrete. External cracks within the garage were cut out and repointed the worst areas reinforced with Thor Heliforce bars and W60 grout. Due to the longstanding distortions within the rear window, insurers elected to replace the frame but having squared the aperture, the replacement was an easy fit. The entire garage work took 5 days to complete and cost £12K. We estimate the cost of rebuilding a double garage with fibreglass roof on a new piled raft to be in the region of £40K.
In addition, the insured and her technical representative are delighted with the results.

After – The garage is level and the distortions and gaps around the window reveal have closed
