RMD Superslim used as Flying shores and raking props

Structural Propping and Shoring W1 Basement

We were asked to produce a temporary works design, After completing the design we were appointed to install the heavy propping to the basement. We installed a row of RMD Superslim soldiers(Slimshores) walers which were capable of carring the high loads and allowed enough of a working area for the excavation. Whilst being able to fix these props without the use of a crane. Which is essential in restricted areas like this one. We then installed the raking props and eventually the Slimshore (RMD Superslim) flying props. This completed the upper layer of the Structural propping. Needling and Jacking were fixed also on this project.

Erection of Temporary Protection Car Parking Shelter

Design

The BBC approached us to Create a safe environment for some of thier radio stars to park thier cars during the Broadcasting house refurbisment. Our designer came up with a shelter using Doka formwork panels.

Installation

We had to erect these panels in two hour time frames, which was the time between the disc jockeys leaving site until 6.00pm. This was of course challenging, however as we had a number of crews working in the area at the time we were able to successfully manage it.

RMD Megashor Tower with Superslim bracing

Facade Retention, Propping and Temporary Works for Kier Construction

Kier approached E P Rothwell and asked us to come up with a temporary works design to secure the facade also design and install the temporary works solutions to this large interesting and demanding project.

E P Rothwell surveyed and produced a thoughtful design which eliminated the temporary works clashing with the new build. RMD Megashor columns were stood outside the building. Held together using RMD Superslim (Slimshore)beams. Mabey Mass 50 was fixed inside the building to support a concrete lift shaft isolated during the demolition. Alshor Plus aluminium was installed throughout the interior of the building. Diamond drilling was needed to allow props to pass concrete floors that were to come out early in the project. RMD Alshor Plus was used on in several ares internally.

Basement Structual propping was placed using RMD Superslim soldiers (Slimshore) raking props around the perimeter of the building and large areas of concrete slab were supported during the demolition stage.

E P Rothwell are delighted to say not only was our contract finshed sucessfully but also three weeks ahead of target.

Between two of London's  Stations King's Cross and St Pancras

Great Northern Hotel Kings Cross to St Pancras Link

Kier appointed E P Rothwell & Sons Ltd to complete the following tasks on the Great Northern hotel

Temporary Works Design, Heavy Propping,Facade Retention Design and installation,Needling,Pull out Tests,Monitoring,Diamond Drilling,Concrete and Structural Steelwork, reinforced concrete

We first conducted pull out tests in the existing Brickwork and concrete. then we set up a monitoring system to measure any movement in the building during demolition and construction.

We then fixed the Basement propping and shoring at the lower level using RMD flying Megashor props,Maybey Mass 50 and Mabey 25 raking shores were installed to lower level basement. Titan propping was used to support the upper basement floor.

Facade Retention and Basement

We then designed and installed the facade retention to the front external walls, continuing around the rest of the building in RMD Super slim (Slimshor) and megashor equipment. Basement shoring supported the external walls using Super Slim raking props as The basement slab was removed and we proceeded to underpin the main load bearing walls. Further basement propping on the internal walls. RMD Super Slim (Slimshor) plan bracing added to the support on the external walls. Then we designed and installed permanent steel pins to shore the structural walls reinforced with rebar placed formwork and concreted in a beam at ground floor level.

We then adjusted levels of floors in building using Hydraulic jacking While this was in progress we backpropped the floors using a combination of RMD Super Slim, Alshor plus and Megashor as well as Maybey mass 25 Propping,bracing and shoring was installed on internal walls. Plan bracing was fixed to corners of the building. Tempoary work foundations were design and installed by EPR. Heavy Propping was then used to support the bigger internal floors Kier Tempoary works department and EPR continued with temporary works design .

With the Facade Retention system in place, needling commenced on the facade to enlarge openings and EPR designed fabricated and fixed the new structural steel frames.The permenant steel now in place chemical dry packing completed. The heavy propping and needling equipment was dismantled Steel pins wrapped in rebar were designed and fabricated by EPR and incorparated in the high level concrete beams. Which were lifted on Hydraulic jacks to new position.We then braced and jacked all the internal floors and walls.Stuctural steel beams were then fabricated and installed internally. The rear external elevation at the request of the client was accelerated to assist parellel projects. This involved Adjusting some of the RMD Megashor towers, To allow the RMD Super slim props and needles installed. We then demolished brickwork in openings and installed Steel frame.

This was achieved despite the orginal programme being demanding

We Completed all the Reinforced concrete as the work progressed.

Dismantling of the RMD megashor towers,slimshore plan bracing and the Maybey mass 50 Propping systems proceeded

Kier and their Client Were both very happy with our contribution, indeed the client took our Supervisor Zydrunas Jasaitus all the way to Paris for a thank you lunch. Which was very much enjoyed and appreciated.

Stan Smith the Kier project Mananger was happy with our work has recommended us on several projects since.

RMD Superslim Needling system secures substansti  timber beam

Phases 2 and 3

Facade Retention and Structural Propping

After suceesfully completing Carriage Hall Temporary Works, We were asked to design and install the Flying props and the high level needling to the next two projects. We also conducted several pull out tests in the brickwork. We created an ambitious design that comprised of RMD Superslim soldiers used as both walers and Props across this building. We used alshor Plus to support the internal timber floors. The external walls were secured using a plan brace made of Mabey mass 25 solders set against the corners of the structure. Basement propping progressed at the same time using the RMD (Superslim) slimshore system. Titan aluminium props provided additional support to the Basement shoring. A high level Needling system was installed in project 2 (see Picture ) this allowed a large steel framed opening to be formed.

pavement over a coal vault next to a fine facade

Crane support on under pavement vaults

Coal cellars beside significant building Facade in central London

Under pavement cellars or vaults are be found mainly in Georgian,Victorian and older properties in Central London. These were orginally used for coal which was poured from above by the road through a hole in the footpath into the cellar or vault. They can be used today in many wonderful ways wine cellars or storage or even an extentsion of the basement living area.

Propping up a crane over a basement space is a challenge

We were asked to dsign the propping to allow a very large crane which during its task of lifting.Would impose loads onto the six coal vaults along the the front of the building. We used the scaffold tube system you can see in the photgraph, Our designers always try to create the most cost effective method of the use of tempoaray works.

RMD Megashor and Superslim systems

Design Brief

The high wind loads that the brick walls were subject to made this a considerable Challenge. The phasing of temporary works and installation of the tower structure required careful sequencing to ensure that the temporary works held the existing structure in place, and maintain stability of the façade at all times, and would also consider the installation of the permanent works.

Erection Sequence

RMD superslim walers were installed, these were bolted to the Megashor tower using tracked booms for safe access.The megashor was erected sequentially as the walers were installed. Maybey 160 props were used in the lower basement. Alshor plus was the preferred system in the existing retained structure. because it is designed with increased safety features including integrated ladder access, integrated platforms, board bearers, handrails and advancing handrails.

A corner bracing arrangement was considered the best option for this east london site. this system gave the reassurance that the neighbours party wall surveyors needed. This arrangement is made of almost all rmd superslim and is tied together using scaffold tube.

ISG Peterborough Shopping Mall

Peterborough Shopping Centre

Design

ISG asked E P Rothwell to create a temporary works design for a steel frame and a Structural propping system. This needed to be done while the precinct remained open so the temporary works design had to account for this and allow for quick installation so causing the least distruption. We therefore fabricated the steel in our workshop in Staines and used bolt connections where possible to reduce hot works on site. As this was a large steel frame over eighty tons which was providing support throughout the precinct it was quite a challenge. We also fixed RMD superslim (Slimshore), Megashor and Alshor plus to provide support for the walls and floors to the mall. Maybey Mass 50 was used in basement areas. ISG were happy with our performance on this challenging contract.

100 ton props holding up a huge car park

Megashor Propping

RMD Megashor was used to prop and lift the level of this car park, Using a megashor spanner we were able to lift the level of this car park 80mm, without the use of hydraulics. In the other picture Superslim is used as corner bracing,this method reduces the need for equipment as we have used the existing building structure to create the strength and stabilty required. Reducing the amount of equipment required,which allows more space and costs less money.

Facade Retention and Structural Propping

Clivden House Structual propping and Shoring Including Concrete works

Stepping in at Short notice.

We were asked to construct the garden swimming pool after the orginal contractor realised he could not construct the pool to the exacting tolerances. We took over and set out the area again. We produced temporary work designs for the formwork.We took up and relaid the blinding, We then placed the reinforcement for the slab.We carefully poured the slab and kickers to produce an accurate base.

After fixing the water bar We placed back shutters and boxed out the openings. Wall rebar was fixed and internal shutters placed and fixed. after concrete was placed and the formwork struck a 28 day water test found that there was no loss from the structure. The mosaic tilers were delighted to have such a precise structure to work on

Following on from the above we were asked to set construct a spiral staircase in the tower which was also completed sucessfully. E P Rothwell are proud to have been involved in this project on this prestigious and historic building.

Early stages of Installation of MGF Hydralic Props

Heavy Propping

Design and choice of correct equipment

High loads in a basement, which is in a restricted location. We as a company are not restricted using to one method or system. MGF hydraulic props were picked and proved an excellent choice. In other areas of the site we used RMD Megashor and Superslim to provide addtional support.
