The top 3 mistakes construction firms make when lifting.

Every year, lifting operations account for a disproportionate number of construction incidents, project delays, and avoidable costs. After two decades working across major infrastructure projects—from HS2 and Crossrail to nuclear power stations and commercial developments—we've seen the same mistakes repeated on sites throughout the UK.The issue isn't usually equipment failure or operator error. It's systemic problems in how lifting operations are planned, resourced, and executed. Here are the three most common mistakes construction firms make, and more importantly, what they cost you.

Mistake 1: Treating Lift Plans as Paperwork Exercises

The Problem:We review dozens of lift plans every month, and the pattern is always the same. Plans that were clearly rushed. Copy-and-pasted from previous jobs without adjustment for the current site. Generic risk assessments that don't address the actual hazards present. Method statements filled with boilerplate language that sounds professional but says nothing specific about the lift you're actually planning to execute.The mentality is understandable. You're under time pressure. The crane's booked. The client's waiting. Writing a comprehensive lift plan feels like an administrative burden standing between you and getting on with the actual work.The Reality:A poorly written lift plan doesn't save time—it destroys it. Here's what actually happens:When your rushed plan hits the review stage, it gets immediately kicked back. Questions that should have been answered upfront now require clarification. Site surveys that should have been completed need to be scheduled. Suddenly your two-day approval turnaround becomes two weeks. The job delays. Crane hire costs continue accumulating. Your client isn't happy. Your programme slips. And everyone's frustrated because it was entirely avoidable.We've seen projects delayed by weeks because someone rushed a lift plan on a Friday afternoon to hit a submission deadline. The irony? Taking three hours to write it properly would have saved days—potentially weeks—on the backend.What Gets Missed:When you treat lift planning as a box-ticking exercise, here's what typically gets overlooked: Accurate load calculations: You've estimated the weight based on similar previous lifts, but you haven't accounted for rigging weight, or the fact that this component is a different specification, or that it'll be lifted with temporary supports still attached. Site-specific ground conditions: Your plan assumes ground bearing capacity is adequate because the previous site was fine, but you haven't verified it for this location. Or you've noted ground protection is required but haven't specified what type, thickness, or coverage area. Environmental factors: You've acknowledged weather restrictions exist, but you haven't checked the actual forecast for your lift window, or identified what your specific wind speed limitations are for this crane configuration and load profile. Proximity hazards: You've marked overhead power lines on your site plan, but you haven't calculated clearance distances for the full radius of crane operation, or established exclusion zones, or confirmed what isolation procedures are required. Coordination requirements: Your plan identifies that other trades are working in the area, but you haven't specified how you'll coordinate with them, what exclusion zones you need, or what the communication protocol is. Each of these seems minor when you're rushing to complete the document. Each of these can stop your lift dead when you arrive on site and realise the plan doesn't match reality.The Solution:Write your lift plan as if you're the one operating the crane. Because if you're working with Cambridge Lifting Services on a contract lift, we are.A proper lift plan includes: Verified load weights, not estimates. If you don't know, weigh it or get the manufacturer's data. Site-specific ground bearing calculations with specified protection measures if required. Weather restrictions for your specific crane, configuration, and load—not generic statements. Measured clearance distances to all proximity hazards, with documented control measures. A detailed sequence of operations that accounts for how the lift will actually be executed, not just the start and end points. Contingency plans for what happens if conditions change. Yes, this takes longer upfront. But a comprehensive lift plan written carefully gets through review faster than a rushed one that needs three rounds of corrections. Time spent in proper planning is never wasted—it's just moved from the back end where it causes delays to the front end where it prevents them.

Mistake 2: Choosing Equipment Based on Availability Rather Than Suitability

The Problem:You need a crane. You ring around. Someone has availability next week. The capacity looks about right on the load chart. Booked. Job done.This approach works fine for straightforward lifts in open sites with good access. It's catastrophic for anything more complex.The Reality:Crane selection is not just about lifting capacity—it's about reach, ground bearing requirements, setup space, slewing radius, obstacle clearance, jib configuration, and how all of these factors interact with your specific site conditions.We've attended sites where the crane that was booked was theoretically capable of the lift, but: Required ground protection that wasn't available or wasn't factored into the programme Couldn't achieve the required radius without extending the boom to a configuration that exceeded ground bearing capacity Had a slew radius that conflicted with site boundaries, adjacent buildings, or overhead power lines Required a setup footprint that didn't physically fit in the available space Needed access routes that weren't suitable for the crane's weight or dimensions In each case, the crane had to be stood down, rebooked, or reconfigured—costing days of programme time and tens of thousands in abortive costs and delay.What Gets Overlooked:When you select equipment based on availability rather than suitability, you miss: Radius requirements under actual load: The load chart shows capacity at various radii, but have you confirmed the exact radius you need from your crane position to the final set-down point? And does that radius change as the load travels through the lift? Ground bearing pressure across the full setup: You've checked the crane's maximum outrigger load, but have you verified ground conditions across all outrigger positions? One weak spot means the entire crane can't operate. Setup space versus available space: The crane manufacturer's spec sheet shows the required setup footprint. Have you actually measured whether that fits in your available working area, accounting for exclusion zones, site boundaries, and other site activities? Transport and access logistics: Can the crane actually get to your site? Road restrictions, bridge weight limits, overhead clearances, turning radii—these aren't theoretical concerns, they're project stoppers. Jib configuration and obstruction clearance: You've focused on the hook position, but what about the jib's travel path? Does it clear buildings, power lines, trees, or adjacent structures throughout the full slew range? The Cost:Selecting unsuitable equipment doesn't just delay your project—it multiplies costs: Crane mobilisation and demobilisation costs for equipment that can't operate Standby time while alternative equipment is sourced Programme delays affecting other trades and milestones Client relationship damage and potential liquidated damages claims Emergency hire premiums for replacement equipment at short notice We've seen firms spend £15,000 on a crane that couldn't complete the lift, then spend another £25,000 on a larger crane with longer lead time, when the correct crane specification would have cost £18,000 if selected properly from the start.The Solution:Select equipment based on a complete understanding of your lifting requirements and site constraints: Define your actual lifting requirements: Load weight (verified, not estimated), lift radius, lift height, slew requirements, and set-down position—all confirmed by site measurements, not assumptions. Assess your site constraints: Ground conditions (with bearing capacity data if available), available setup space, access routes, proximity hazards, and site boundaries—all verified by site visits, not drawings alone. Consult with your lifting provider early: Share your requirements before you book. A reputable lifting company will help you select appropriate equipment or identify issues before they become problems. If someone's willing to book a crane without asking detailed questions about your site and lifting requirements, that's a warning sign. Factor in contingency: If your lift is marginal on the load chart, or your crane positioning is tight, or your ground conditions are questionable—specify equipment with margin built in. The cost difference between an adequate crane and a crane with contingency capacity is minimal compared to the cost of getting it wrong. When Cambridge Lifting Services quotes for a contract lift, we're not just offering a crane—we're offering a solution. That means site visits, ground assessment, proximity surveys, and equipment selection based on complete understanding of your requirements. It costs more upfront than a phone quote based on a brief description. It costs far less than getting it wrong.

Mistake 3: Underestimating the Importance of Competent Personnel

The Problem: You need an operator. They've got the right ticket. They're available. They're booked. Sorted. This is perhaps the most dangerous assumption in the lifting industry: that certification equals competence for any job. The Reality: A ticket proves someone passed a test. It doesn't prove they have experience with your specific equipment, in your type of environment, handling your type of loads. And it certainly doesn't prove they have the judgment to recognise when something isn't right. We've seen it repeatedly: qualified operators who are brilliant with their usual equipment but completely out of their depth on a different application. Competent slingers who don't understand the load characteristics of the materials you're handling. Banksmen who've worked on open sites but have never coordinated lifts in congested urban environments. The result? Inefficiency at best. Incidents at worst. What Competence Actually Means: Competence isn't just about technical ability—it's about matching skills and experience to the specific demands of your lift: Equipment-specific experience: A crawler crane operator isn't automatically qualified for tower crane work. Someone experienced on mobile cranes may struggle with the different operating characteristics and sight lines of a tower crane. Certification covers basic operation—experience covers the nuances that matter on site. Load-specific knowledge: Lifting structural steel requires different skills than lifting mechanical plant. Handling precast concrete panels isn't the same as lifting loose materials in skips. Someone competent in one doesn't automatically transfer that competence to the other. Environment-specific judgment: Operators experienced on open construction sites may lack the judgment required for lifts in congested areas, near live railways, or in proximity to existing structures. The technical operation is the same—the risk assessment and decision-making are completely different. Communication and coordination: The best operators we work with are exceptional communicators. They brief their teams clearly. They confirm understanding. They speak up when something doesn't feel right. These aren't technical skills—they're professional skills, and they're just as important. What Gets Missed: When you select personnel based solely on certification rather than genuine competence, you risk: Inefficiency: Operators unfamiliar with equipment take longer to complete lifts, require more instruction, and make more positioning adjustments. A competent operator completes in one hour what an inexperienced but certified operator takes three hours to achieve. That time costs money. Poor decision-making: The judgment to stop a lift that doesn't feel right—even when everything looks okay on paper—comes from experience, not a laminated card. Inexperienced operators press on when they should pause. That's when incidents happen. Communication breakdowns: Lifting operations require constant, clear communication between operator, slinger, banksman, and site personnel. If your operator doesn't have experience working in coordinated teams or complex environments, that communication often breaks down. Confusion leads to errors. Increased supervision requirements: Inexperienced personnel require more oversight, more instruction, and more intervention. That means your site management spends time supervising lifting operations instead of managing other aspects of your project. The Solution: Choose personnel based on relevant experience, not just certification: Ask specific questions: What experience do they have with this type of crane/equipment? Have they worked on similar projects or in similar environments? What's their experience handling this type of load? Can they provide references from similar work? Involve them in planning: The best operators we work with ask questions during the planning phase. They want to understand site constraints, load characteristics, coordination requirements. If an operator just shows up expecting to be told what to do without engaging with the planning, that's a concern. Value judgment over speed: The operators who admit when they're uncertain or when something doesn't feel right are worth ten times more than the operators who claim they can handle anything. Experience teaches you what you don't know. Overconfidence is dangerous. Invest in continuity: If you're running a project with ongoing lifting requirements, having the same competent personnel throughout provides enormous value. They learn your site, understand your materials, build relationships with your team. That familiarity translates to efficiency and safety. When Cambridge Lifting Services provides personnel for contract lifts, we're not just sending someone with the right tickets. We're sending people we'd trust to operate our own equipment. People with relevant experience. People who ask questions. People who'll tell you when something isn't right rather than pressing on regardless. That's what competence actually means. The Common Thread These three mistakes—inadequate lift planning, unsuitable equipment selection, and undervaluing genuine competence—share a common cause: treating lifting operations as a commodity service rather than a specialist discipline. The mindset that any crane, any operator, and any lift plan will do if it meets the basic requirements is exactly what causes avoidable delays, cost overruns, and incidents. Lifting operations aren't a checkbox on your project plan. They're often the critical path activity that determines whether your programme succeeds or fails. They deserve the same rigour, planning, and investment in quality that you apply to every other aspect of your project. The firms that understand this—that invest time in proper planning, select equipment based on suitability rather than availability, and value genuine competence over basic certification—consistently deliver projects on time, on budget, and without incidents. The firms that don't are the ones calling us to solve problems that shouldn't have existed in the first place. Which type of firm do you want to be? Cambridge Lifting Services provides crane hire, contract lift, lift planning, and LOLER inspection services across the UK. Our team has operated on major infrastructure projects including HS2, Crossrail, and Hinkley Point C. We understand what good lifting operations look like because we've delivered them on some of the most demanding projects in the country.
