Abstract: A method of slip forming a concrete structure can include using a first slip form mold that travels along a path to form a portion of a concrete structure by delivering a first flow of concrete into the first mold through a first hopper. The first hopper can be configured to receive the first flow of concrete. The portion of the concrete structure can be modified using a second slip form mold different from the first mold by advancing the second mold along the concrete structure and, while advancing the second mold, delivering a second flow of concrete into the second mold through a second hopper that is configured to receive the second flow of concrete.

Abstract: Systems and methods for the continuous slip form construction of concrete barriers over support cages. A tube feeder of a slip form construction system can include angled tubes that can direct reinforcing bars into a concrete barrier and also provide space between the tubes for insertion of a support cage through the system and into the concrete barrier.

Abstract: The lighting equipment comprises a lighting device with a plurality of light sources for delivering white light having a tunable light spectrum, and a monitoring and control device that controls the light sources in a modulation cycle for modulating the light spectrum, which cycle comprises a first period where the light spectrum is red-enriched, a second period where the light spectrum is gradually modulated from red to blue, a third period where the light spectrum is blue-enriched, and a fourth period where the light spectrum is modulated gradually from blue to red. The control device is arranged to detect reception of a signal indicating a human presence, and, in response, reinitializes the modulation cycle when the modulation cycle is in the first period, or gradually modulates the light spectrum from blue to red when the modulation cycle is in the second, third or fourth period before reinitializing the modulation cycle.

Abstract: A system for making slotted drains of slip-formed concrete can comprise concrete, a block, a drain path forming structure, a hopper and a mold. The hopper can be for receiving concrete and for providing concrete to the mold for molding concrete. The mold can comprise a drain member guide, a topper, a first side and a second side. The drain member guide can be configured to slide over the drain path forming structure and wherein the hopper can be configured to provide concrete around the drain member guide. The topper, first and second sides can be for molding the top, first and second sides of the slotted drain respectively. The second side can also be configured to create a slot in the slotted drain and to selectively hold the block, the slot configured to selectively receive the block.
