There are many ways to build a commercial building or home these days, but tilt-up construction through Tilt Wall offers the greatest benefits.
This specialized process can be broken down into 6 distinct steps:
1. Site Preparation \u0026 Pouring the Foundation Slab
All required materials and equipment are gathered for the job. Next, the concrete floor slab is poured.
2. Forming of Tilt-Up Wall Panels and Adding Formliners
The crew assembles the panel forms on the floor slab. The panel forms serve as molds for the concrete. Each form provides the panel’s exact shape and size as well as openings for doors and windows
3. Panel Reinforcement and Installation of Lifting Inserts \u0026 Embeds
Up next, workers tie in the steel grid to reinforce bars into each form. This part of the process gives the panels additional structural integrity. Workers also install inserts and embeds, which will be used to lift the panels later
4. Pouring Concrete Tilt-Up Panels \u0026 Adding Insulation
Concrete is poured into the prepared forms to create the panels. Sandwich Insulation is also encased into each building panel. To give tilt-up structures true edge-to-edge insulation.
5. Lifting Concrete Panels in Place
The concrete panels are given time to solidify; The crew then connects the panels to a crane.
The crane then lifts the panels from the floor slab into position. From here, the workers will connect the panel’s braces to the slab. The crew moves to the next panel and repeats this process until all panels are tilted up and secure.
6. Panel Finishings \u0026 Caulking Joints
During the last step of the process, the building begins to look like a finished product. Exterior wall finishes, take place, and the joints are also caulked to prevent water penetration

Design Criteria, Loads & Specifications – EngineeringCivil.org
Deflection Walls or Crash walls
Deflection Walls or Crash walls are huge wall shaped reinforced concrete structures provided for the protection of piers and abutments in the vicinity of railway tracks. The purpose of deflection wall is to prevent head-on collision or impact from derailed trains on the primary structural support elements. It is also called a crash wall. A direct collision of a train on a non-frangible(primary) pier may lead to total collapse of bridge. Deflection wall helps to avoid catastrophic failures of bridges due to collision impact by derailed trains and minimise probability of injury to the passengers of derailed trains.
Deflection Wall provided at Dynon Rail Bridge, Melbourne, Australia
This structural system is mostly found in Australia. Australian bridge design code AS5100 mandates protection of piers near to rail lines. These walls are provided for Rail, Road and Pedestrian bridge piers if distance from face of pier to the centerline of existing or proposed tracks is less than 20m. However, this requirement can be ignored for piers within 10m to 20m range, if a risk assessment is carried out to determine the protection requirements and approved by authorities.
Dimensional Requirements of Deflection Walls
AS5100.2 2017, Clause 15.3.4 sets out dimensional and design requirements of deflection walls. A continuous deflection wall of height 3.6m above rail top shall be provided if the distance of pier face from the center line of existing or proposed tracks is less than 4m. If this distance is more than 4m, the deflection wall must project 2m above the top of rail. Additional dimensional requirements of deflection wall specified in the latest design code are as follows:
Deflection Wall cum Blade Pier
Minimum length of wall is 4m with minimum of 2m longitudinal extension on either sides of pier parallel to track;
with minimum of 2m longitudinal extension on either sides of pier parallel to track; Wall must have minimum thickness of 800mm ;
; Wall shall extend 1.2 m minimum below ground level;
m minimum below ground level; Minimum extension from face of pier shall be 150mm laterally;
Wall shall have rounded ends, smooth face without snagging points.
Angle with rail tracks and wall shall not exceed 20deg.
Design requirements of Deflection walls
Deflection walls are designed as continuous reinforced concrete walls. It must be ensured that the collision forces on the deflection walls are not transferred back to the primary structural element. When the pier face is within 10m from the centerline of track, following design loads shall be considered in the design of deflection wall. These loads shall be applied simultaneously at 2m above the rail top in the horizontal direction.
4000kN parallel to track;
parallel to track; 1500kN normal to track.
Upgrading regular pier with in-situ deflection walls
These loads shall be distributed over a length of 2m x0.5m deep. When piers are located between 10m to 20m from track, the protecting deflection wall shall be designed for a horizontal force of 1500kN applied horizontally 2m above rail in most onerous angle to the wall.

Crash Wall
CHALLENGES
Adhering to state Department of Transportation requirements for construction near an existing, active interstate highway, several design and construction considerations helped shaped project development.
Concern over vibrations and over excavation near existing interstate piling encouraged helical deep foundation design.
Other design and installation challenges included low overhead clearance beneath the interstate bridge, dictating a maximum pile length to allow for access, along with the need for a small construction footprint to ensure no disruption to the everyday operations of both the interstate highway and the railway.
WHAT WE DID
Focused on safe design and construction, TorcSill’s Engineering TEAM developed a “transition” pile to resist high lateral loading while maintaining constructability and significantly reducing the cost of steel used for the foundation. The lead section (helix-flighted section) of the pile was designed as a medium diameter pile, transitioning to a large-diameter section for the top 15 feet.
Each section of the 60-feet pile was designed at 15 feet to ensure adequate access for the installation equipment.
Upon design approval, TorcSill’s Construction Services TEAM conducted load tests to verify pile capacities, before providing survey services to precisely locate each pile placement location.
SOLUTION
The engineered, manufactured, load tested, surveyed and installed Crash Wall Project met all the conditions placed upon the TorcSill TEAM. At completion, 103 transition piles were installed to support an important infrastructure safety project, effectively eliminating vibrations typically associated with driven piles and over excavation and large construction footprint concerns associated with other piling solutions.

Crash walls are required to be installed in most new developments today in Ontario that are adjacent to a railway corridor. These large concrete barriers are required for protection in the event of a train derailment. The management of sound and vibration are other issues addressed by the installation.
As our cities expand, more railway corridors are now a development reality. Crash walls are required for both commercial, industrial and residential land use. Concrete crash walls require specialized experience and engineering. Each project is inspected for site-specific constraints and safety concerns.
Significant changes have been made in recent years to both federal legislation and some provincial land use acts. The original guidelines were reviewed and updated in 2013 by a joint collaboration from the railways, municipalities and government. This pertains to the development of industrial, commercial and residential lands.
The Guidelines for New Development in Proximity to Railway Operations also include the recommended building setbacks for new residential development in proximity to railway operations.
The process of building these large concrete walls is highly intricate. Northland Paving is experienced in building strong and stable concrete crash walls. Northland will also navigate all of the necessary steps in permit co-ordination, inspections, testing and gaining access to rail properties.
Palmetto Expressway Crash Wall, Miami, Florida
Construction of the protective wall along the Palmetto Expressway required to implement the new concrete wall to existing road infrastructure. Our Geopanel formwork was suitable for the creation of reinforced concrete wall that incorporated pillars of the overpass located near a railway. Given the impossibility to use the crane, Geopanel formwork proved to be the most cost-efficient and time-saving solution.
Geopanel was chosen because of its benefits:
Less expense for machinery,
Profitable solution for limited space at the construction site,
Cost-savings for construction with reusable formwork elements,
Lean construction with low waste,
Safer construction site .
