Level three formwork is in place and ready to go! In the distance the columns to support level four on the south end are getting formed.

Petal formwork (15m x 11m) for 8 petalled circular swimming pool ceiling (30m diameter). CAD modelled and CNC cut Plywood and MDF with reference levels and check points machined in allows the accurate construction of the plug. 3D Laser scanning and survey of the as built support steelwork drive the CAd model, allowing maximum accuracy and speed of fitting.
In November 2007 ADIF, the Spanish railway infrastructure administration awarded a joint venture of Acciona (75%) and Obras Subterraneas (25%) the
EUR 113.8 million contract to build the 4.7 km section between Aranjuez and Ontigola. This includes the El Regajal Tunnel.
BarChip was chosen for the
primary secondary lining at
El Ragajel
The total tunnel length in 2,437 m, of which 2,080 m is the excavated tunnel with two cut and cover tunnels measuring 23 m and 224 m at the north east and south east ends respectively. The tunnel will be suitable for a double track.
The difficult and complex ground conditions comprise of clays with high salt
contents that can easily dissolve with low cover at the portals. Ground support
consists of steel sets together with 300 mm of BarChip reinforced shotcrete. Over 10,000 m3 of BarChip reinforced shotcrete will be used for primary ground
support, batched from a specially installed on site batching plant.
In excess of 120,000 m3 of BarChip reinforced concrete will be used for the secondary lining which will be up to 1.0 m in thickness. The concrete will be placed in situ using a 12 m travelling formwork. BarChip is being used to reinforce the secondary lining to enhance its resistance to the harsh ground
conditions over the life of the tunnel. BarChip fibre will not only impart excellent impact and abrasion resistance but it will help reduce any crack propagation.

Reverse Stairs
Day 1: Used AutoCad to get formwork dimensions. It is a repeat of only few shapes, since the steps are a repeat.
Day 2: Cut plywood and pine down, and hauled it over to site.
Day 3: Put wood together just like lego and placed rebar in. Kept tops open at each step, for easy vibration, and it worked great.
When I used to pour concrete as a teenage wanna-be artist, I learned the value of making sure formwork are supported and secure. But yet again I learned from mistakes: each step required 2 poles and it was hardly enough and the nails was close to popping thru.
Day 4: Convincing and Pouring.
We poured the 1st floor (in america 2nd floor) and the steps in one shot.
The concrete subs Foreman was shocked when he walked up to it first. He was sure that no engineer had approved a staircase only supported at the top and bottom.
Only after calling the engineer did he trust the design. I thought that it was elementary and enjoyed the humor of it all.
General notes:
I used my nail gun to put it all together since I figured we'll only do it once (and safe time).
The formwork was almost destroyed when the subs team shot at it with the concrete hose. I quickly had them shoot it at the 1st floor metal formwork deck and then we shuffled it down. Vibration took more time than with any other job since it had to be shifted down.

The modular All Steel Form Panels are bolted together to form vertical strips.
The twin 'Soldier Panels' are then bolted to the backs of form panels to provide enough strength so that the form only requires Anchors below and above the concrete pour.
The full height Panel strip is then crane handled into position and attached to the panel unit next to it. This Heavy Duty method of Construction does away with the need form any Form Ties in the concrete wall.
