    Construction work is no easy feat. Every detail, from the foundation to the finishing touches, requires immense effort and coordination.

    People spend countless hours planning, measuring, and building every aspect of a space, ensuring that everything is functional and safe. But, as impressive as construction is, even the smallest error can lead to some rather amusing—or alarming—blunders.

    Had a helipad installed at our office. On the inspection it was found they had read the plans upside down somehow and instead of being a raised mound they had dug a pit. Just the thing for walking into rotors.

    To better understand how these mishaps happen and their real-world impact, we spoke with Rahul Mishra, a seasoned construction supervisor with 20 years of experience. With projects spanning across various states in India, Mishra has seen it all—both the good and the downright puzzling.

    He began by shedding light on the challenges of the job. “People often think construction is straightforward, but it’s one of the most difficult jobs out there,” he shared. “You’re working with tight deadlines, balancing client demands, and ensuring everything aligns with safety standards. It’s not just building; it’s problem-solving on the go.”

    Most of the posts on this thread are minor inconveniences. This one is serious, a multimillion dollar project that isn't safe to use and where the danger is hidden from the motorists.

    Mishra also highlighted the teamwork involved in construction. “So many people work together on a project that there’s always a chance for miscommunication,” he explained.

    “One person might handle fittings, while another focuses on electrical work. If there’s a slip-up in communication, you’ll end up with something odd—like a door that opens into a wall or stairs that lead to nowhere!”

    Having worked in diverse regions, Mishra shared how client requirements can sometimes be unusual. “You get bizarre requests sometimes,” he chuckled.

    “But our job isn’t to question it—it’s to make it happen. Whether it’s an oddly shaped balcony or a room with no windows, we just do our job.”

    Mishra emphasized that not all construction blunders result from miscommunication or odd demands. Sometimes, they stem from genuine mistakes. “I remember one case where a worker didn’t know how to install a bidet properly. What was supposed to be a simple installation turned into water spraying in all directions—it was a mess!”  

    While these mistakes are often fixable, Mishra acknowledged that the costs can be significant. “Rectifying errors can cost a lot of money,” he said. “It’s not just about the materials—you’re paying for labor, revisiting plans, and sometimes even replacing entire sections of work.”

    This would be OK if it was in a private apartment on an upper level. One of the posh hotels in Melbourne (Australia) has a men's toilet and washroom on the 20th ... something floor, where you can pee and enjoy the views over the city. It's quite an experience and no one can see you doing it !

    Highlighting the risks, Mishra noted that some errors could even pose safety hazards. “If a mistake isn’t caught in time, it can create serious problems down the line. For example, poor plumbing or electrical work can lead to dangerous situations. That’s why attention to detail is crucial.”

    This has undoubtedly been closed off because the steps have degraded, making the staircase dangerous. So arguably the materials used may have been a poor design choice for this location (in conjunction with environmental conditions and lack of maintenance), but the fact that the stairs don't currently go anywhere would be a remedial situation, not the intentional design.

    The building looks like a Georgian-era warehouse or factory, so that would have been for getting heavy goods in or out that were too heavy to take up the stairs. There will have been a block-and-tackle lifting device fixed above the door.
