A formwork element for a molded wall panel end, comprising: a sole plate having a first lateral edge, a second lateral edge, an outer face, an inner face bearing a caisson, said caisson leaving free, on the inner face of the sole plate, a first lateral zone, defined between the first lateral edge and the caisson, and a second lateral zone, defined between the second lateral edge and the caisson; a form stripping assistance device cooperating with the sole plate. The form stripping assistance device includes at least one first sacrificial section comprising a first portion disposed on the first lateral zone of the inner face of the sole plate.

A method of constructing multiple conduits in building foundations that eliminates the process of core drilling after the foundation has been poured and set. This method creates optional openings for possible future connections. The process uses removable conduit molds installed before the foundation is poured. Once the foundation has set, conduit molds are removed to explose conduits in the foundation as needed.

The invention relates to a formwork device (10) for an end of a panel of a molded wall, said formwork device extending along a longitudinal direction (A) and comprising at least one first formwork element (20) including: a base (22) extending along the longitudinal direction (A) and having an outer face (24); a housing (28) interacting with the base and extending along the longitudinal direction; at least one measuring device (40) making it possible to determine at least one first deviation parameter (d1) representative of the deviation of the base (22) with respect to a first vertical plane (P1); and a signal-transmitting device (50) connected to the measuring device (40) to transmit the first deviation parameter α1, d1, β to a reception station (60) located at the surface.

Provided are apparatus and method(s) for forming one or more shear key(s) between embedded concrete retaining wall(s) and concrete floor slab(s), kits for forming such shear key(s) and underground structures such as embedded concrete wall(s) and slab(s) comprising a shear key. In particular, the invention relates to a shear key former apparatus comprising: a box having an enclosable, internal volume, the box comprising a base and at least one, and preferably four, side wall(s), the side wall(s) terminating in a rim; rearwardly of the rim in two opposing portions of the side wall(s), at least one pair of opposing apertures, each pair of apertures defining an entrance and exit in each respective side wall portion for a rigid member to be accommodated extending across the internal volume between the entrance and the exit; a closure panel configured to be received into the rim to enclose the internal volume.
