COLUMN CRANKING This is becoming a new normal in most construction sites. They call it pillar cranking. I personally hate this thing with all my being. The cause of this pillar going out of alignment is poor setting out and poor setting of footings. If I'm around I always make sure there's LxB lines during setting out of columns People do this After discovering that the pillar is out of line where structurally it should be, the contractor or foreman will call his iron bender to use his bar and bring it into the right position. If you have 30 to 35 columns in a foundation and about 7 to 5 are like this, you have done an improper setting out or you did not supervise your excavation activities properly. Note that not all pillars that you will apply this method of correction to and it will not have an impact on the structure's integrity. That is why setting out and setting footings and columns is a very important activity and should be done by a professional. This type of Cranking can affect the structural integrity of buildings. #civilengineering #construction #projectmanagement #projectengineer ✍️ Cc KnoxConsult

Cast-In-Place or Precast Concrete?   The evaluation of pros and cons is a critical exercise in decision-making, allowing us to weigh the benefits and drawbacks of various options.   Cast-In-Place 🟦 - directly poured at the construction site - offers flexibility, but requires more on-site labor - weather conditions can cause delays - no need for cranes, for large components that would be hard to transfer   Precast 🟩 - pre-made (off-site) delivered to the construction site - less on-site labor - weather conditions won't affect construction - necessity for cranes - compressive strength - 50 MPa without reinforcement - smaller cost of labor and remedial works due to error   What's yours experience with Precast?   #precast #castonsite #engineering #consultants #petruf #modernmethodsofconstruction #concrete MMC Ireland

If you've ever installed site utilities or brought a new building out of the ground during winter months, you know that maintaining, let alone gaining against a project schedule through that period is a real challenge. Knowing a number of working days will inevitably be lost, overcoming the winter season hurdle requires a heightened level of awareness and diligence around planning as well as ensuring your project team is unified behind the commitment to work larger crews, longer hours, and weekends as weather allows. Every once in a while, though, mother nature surprises us with a 6 day stretch of workable, clean (albeit cold) weather. And man was it a thrill to witness what our project team at the Clemson University Chiller Project delivered given that opportunity last week!! Below is a short timelapse video of how our jobsite transformed over last week from Monday morning through Saturday afternoon. Outstanding field oversight by Sam Diestler and incredible execution by our subcontractor partners! #WeAreBuilding Clements Electrical, Inc., McGillicuddy Concrete LLC, Reeves Young Messer Construction Co. - 120 feet of 16-way electrical duct bank excavated, 2100 feet of 4" conduit installed buried an average of 7 feet deep, and 60 CY of concrete poured ☑️ - 130 feet of shallow spread footings averaging 16' wide excavated, double mat re-steel installed, anchor bolts set, and 270 CY of concrete placed ☑️ - 350 yards of spoils replaced and compacted to release the next section of shallow footings to the concrete subcontractor ☑️

The steel gridshell roof structure of Shell’s C30 building could not rest on the scaffolding. Therefor, we installed the steel frames in in a specific order, as a reciprocal frame. First, we installed the edge beams, followed by the tension rods, after which the corner frames and other frames were added, progressing towards the centre. A square-shaped void of 21x21 meter remained in the centre of the roof. The last part of the frame had to work as a reciprocal frame. Working with two cranes at the same time, we installed the final four ladder frames. Each frame provides support to its neighbour, while also receiving support in return. The interlocking frames complete the roof, creating a structurally stable construction that does not need any central support. Besides the smooth assembly process in which the reciprocal frame was placed in just 7 hours, we take pride in witnessing its’ perfect fit. It showcases the far reaching perks of advanced prefabrication. Nothing but praise to our colleagues at engineering, production and assembly and their dynamic collaboration from the moment the drawing was on our table.

Efficiently transporting and launching segmental box girders for modern bridge construction Transportation and launching of segmental box girders involve careful planning and execution to ensure safety and efficiency. These girders, often used in bridge construction, are prefabricated in segments, allowing for easier handling and transportation. During transportation, specialized vehicles, such as flatbed trucks or barges, are employed to move the segments from the fabrication site to the construction site. Once on-site, cranes or launching gantries lift and position the segments into place, ensuring precise alignment. The segments are then connected using high-strength bolts or welding techniques. This method minimizes on-site construction time and reduces disruption, making it an effective solution for modern infrastructure projects, especially in challenging environments or urban settings. video rights : Respective owners DM for removal/credits #bridge #bridgeconstruction #segmentalboxgirder #bridgedesign #engineering #civilengineering #civilconstruction #engenharia #engenhariacivil #engenheiro #engenheirocivil #ingeniero #ingenierocivil

"Efficient and Safe: Lifting Steel Columns with Chain Pulley Blocks" Lifting structural steel columns using chain pulley blocks is a common method in construction. Chain pulley blocks, also known as chain hoists, utilize a chain looped around gears to lift heavy loads with minimal effort. The process involves attaching the chain pulley block to a secure overhead support and connecting it to the steel column. By pulling the chain, workers can lift and position the column accurately. This method offers precise control and safety, making it ideal for erecting steel structures efficiently and effectively, ensuring proper alignment and stability of the columns. video rights : Respective owners DM for credits/removal #structural #engineering #civilengineering #mechanicalengineering #construction #civilconstruction #engenharia #engenhariacivil

Engineering is in the design, implementation and certainly in maintenance/conservation!

From demolition to completion

Lifting Steal Structure Columns: (With Chain Pulley Blocks)

Chain pulley blocks streamline the lifting of steel columns, merging efficiency with safety. Their precise control ensures accurate positioning, essential for the stability of steel structures. However, how are we addressing the potential risks of manual operation fatigue? Could automation enhance safety without compromising control? Moreover, in the quest for efficiency, are we considering the wear and maintenance of these tools to prevent accidents? Ensuring a balance between human oversight and mechanical reliability is crucial for advancing construction safety and effectiveness. #ConstructionSafety #EfficientBuilding #EngineeringInnovation
