The client was injured when she was caused to fall in a landing area at the amusement park, resulting in a fractured ankle. Liability was disputed. The amusement park denied responsibility and claimed that the landing area had been properly maintained and was reasonably safe for guests.

- $300,000 Settlement for Dog Bite Victim Attacked at Dorchester Multi-Family Rental PropertyMassachusetts Lawyers Weekly recently highlighted a $300,000 Dorchester dog bite settlement obtained by Gavagan Law, LLC involving injuries at a Boston multi-family rental property.

The client suffered puncture wounds to both thighs and permanent scarring. The case involved claims against the dog owner, dog keeper, and non-resident landlord. Through independent investigation, including animal control records and tenant interviews, we established that the dogs had been involved in prior incidents at or near the property and that steps were not taken to protect tenants and lawful visitors. Although the defendants initially failed to cooperate and insurance coverage was not disclosed, we identified applicable premises liability coverage through further investigation and resolved the case for the landlord’s full available policy limits of $300,000. , 2026

White Papers
- Boston Construction Accident Lawyer – Third-Party Claims for Serious Job-Site & Roofing InjuriesConstruction sites power the construction industry, but when occupational safety fails, injured workers face serious injuries, mounting medical bills and medical expenses, and aggressive insurance companies. If you were hurt on a job site anywhere in the Greater Boston Area—Boston, Dorchester, Quincy, South Boston, Middlesex County, Suffolk County, Essex County, Norfolk County, Bristol County, Plymouth County, Worcester County, or Fall River—you may have two paths: Workers’ compensation benefits through the workers’ compensation system, and a third party (or third parties) personal injury claim against a responsible party other than your employer (property owners, general contractor, other subs, traffic-control vendors, heavy machinery or safety-gear manufacturers, or a negligent driver in a work-zone crash). Gavagan Law, LLC is a boutique law firm with extensive experience helping construction workers secure full compensation for workplace injuries and work-related injuries. Cape Cod Amusement Park Injury I was injured in an amusement park accident on Cape Cod, MA, and Attorney J. Finn Gavagan at Gavagan Law, LLC did an excellent job handling my case. He really understood the …Read more“Cape Cod Amusement Park Injury”Abby Premises Liability Read more testimonialsPrevious SlideNext SlideConstruction Site Accidents Blog Workers’ Comp vs. Third-Party: What’s the Difference?Workers’ CompensationNo-fault medical care and a portion of lost incomeNo pain-and-suffering damages Benefits can be delayed or disputed by a workers’ compensation insurer; documentation still mattersThird-Party ClaimTargets non-employer wrongdoers (property owners, general contractor / construction manager / joint venture, other subs, product makers, motorists) Allows pain & suffering, types of damages including full lost earnings/earning capacity, scarring, loss of consortium, punitive damages in egregious cases, and future physical therapy and medical careMost Massachusetts construction site accident claims have a three-year limitations period (don’t wait—evidence disappears)Many construction accident cases involve both tracks. We coordinate benefits, preserve evidence, and address any lien so you get the best possible outcome and a fair settlement. Who (Else) Can Be Liable for a Construction or Roofing Injury?Property Owners / Developers – unsafe or hazardous conditions, inadequate coordination, unsafe conditions at the construction project General Contractor / Construction Manager / Joint Venture – site-wide safety regulations, fall protection, sequencing, enforcement of safety standards Other Subcontractors – debris, dropped loads, faulty wiring, energized work near your crew Equipment & Safety-Gear Manufacturers / Rental Companies – defective lifts, cranes, nail guns, saws, ladders, anchors/lifelines/harnesses Architects / Engineers – design or temporary-works failures Traffic-Control Vendors & Motorists – dangerous workplace accidents in work-zone areas Our experienced construction accident attorney team identifies who actually controlled the hazard and who promised to inspect, guard, or coordinate the task that led to the serious injury. Common Construction & Roofing Accidents We HandleFalls: scaffolds, aerial lifts, ladders, roofs, unguarded openings/skylights Rooftop/edge incidents: missing guardrails, improper tie-off, swing-fall, unsafe access/egress Struck-by: falling objects, load drops, vehicle/equipment strikes involving heavy machinery Caught-in/between: trench/excavation collapses, pinch points, inadequate machine guarding Electrocution & arc flash near energized lines or temporary power; hazardous substances exposure Crane/hoisting & rigging failures and load-path errors Explosions/Fires (gas/propane), hot-work burns Defective tools & machinery (nail guns, saws, presses, lifts) Road-work zone crashes involving passing traffic or delivery trucks Fatal Rooftop & Edge Falls A single missed detail at a roof edge can cause fatal injuries. Construction accidents related to roof falls and roofing-site injuries are preventable. If you (or your spouse) were hurt on a roof in Boston, Dorchester, or the Greater Boston area, we perform thorough investigates including identifying OSHA fall-protection violations to hold negligent contractors accountable. Why deadly roof falls happen (and how we prove it)Fall protection & edge control: missing/inadequate guardrails, warning lines, or safety monitor; no toe-boards on steep-slope roofing; “leading-edge” work without protection.Personal fall-arrest system (PFAS) failures: no harness, wrong tie-off, anchors not rated 5,000 lbs or placed incorrectly; lanyard too long; swing-fall hazards; damaged lifelines/SRLs; no rescue plan.Access & egress: unsafe ladder setup or tie-in; no three points of contact; makeshift roof jacks/roof ladders; temporary stairs without handrails; congested or cluttered edge access.Unprotected openings: uncovered skylights, roof/floor/shaft holes, unguarded roof hatches, phased decking not fully planked or covered.Surface conditions & housekeeping: wet/windy or icy roofs; loose debris and nails; poor lighting; materials staged at the edge creating trip hazards.Material handling & equipment: crane/hoist/boom-truck moves without a spotter or tag lines; unsecured loads; debris chutes; hot-work/torch-down burns; nail-gun injuries.Training & supervision: rushed schedules, poor hand-offs between subs, no competent-person oversight, lack of documented training on Subpart M fall protection. If you or a loved one fell from a roof or were hurt on a roofing job in Boston/Dorchester, we investigate violations of the OSHA fall-protection rules (§1926.501)—including missing guardrails, uncovered skylights, or improper tie-offs—and hold negligent contractors accountable. We also review guardrail/PFAS criteria (§1926.502) and ladder safety requirements (§1926.1053) that frequently get ignored on busy job sites. For public-sector worksites, Massachusetts has a State Plan covering state and local government employers, while private-sector roofing is enforced by federal OSHA (learn more). For an overview written in plain English, see OSHA’s Protecting Roofing Workers guide (PDF). Severe Injuries & DamagesWe regularly build cases involving spinal cord injuries, traumatic brain injuries, amputations, severe burns, crush injuries, and complex fractures—resulting in long-term health issues, physical pain, and life changes. Your damages package may include: Future medical care & life-care plans Lost income and lost earning capacity (vocational & economic experts) Scarring & disfigurement Pain, suffering, and loss of enjoyment of life Loss of consortium for spouses How We Prove LiabilityPreservation letters on Day One to owners/GCs/subs/vendors and the insurance company Site paperwork: prime contract, GC/CM/JV agreements, subcontracts & scopes, safety plans, fall-protection plans, JHAs/JSAs, toolbox-talk sign-ins Daily reports & inspection logs: superintendent/safety checklists, scaffold/edge/opening inspections (flag missing/blank forms) Condition capture: photos/video; witness statements; measurements of guardrail heights, opening dimensions, warning-line distances, anchor locations Equipment & safety gear: model/serials for harness/lanyard/anchor; inspection tags; installation drawings; rental/vendor records Regulatory evidence: Occupational Safety and Health Administration (OSHA) records (the federal health administration for workplace safety) and National Institute for Occupational Safety and Health (NIOSH) guidance; any citations and post-incident corrective actions Medical proof: medical records, surgery reports, physical therapy notes; union wage + fringe records; overtime history Agencies & process: filings and status checks with the Department of Industrial Accidents; we guide you through the legal process and entire process of legal action What to Do After a Construction Injury Report the workplace injury and get medical attention—document symptoms. Photograph the construction site condition, equipment, and area before anything changes. Get names/contact info for witnesses, foremen, and subcontractors. Save pay stubs, timesheets, job assignments. Avoid recorded statements to insurance companies (beyond basic comp reporting) without counsel. Call a lawyer early to protect workers’ compensation claims and third-party rights. Wrongful Death Damages in MassachusettsFamilies may pursue wrongful death damages for the fair compensation (the fair monetary value) of their loved one—loss of reasonably expected net income, services, and the loss of society, companionship, comfort, guidance, counsel, and advice—plus funeral/burial expenses. In willful/wanton conduct, punitive damages may apply. If there was conscious pain before death, the estate may also recover survival damages.Workers’ comp helps, but it doesn’t make the family whole—hence the need for third-party claims to reach full compensation from the responsible party. Why Choose Gavagan Law?We make it simple to connect—because having a lawyer you trust matters when you’re dealing with serious injuries and medical bills.

Workers’ comp is between you and your employer. A third-party personal injury lawsuit targets negligent third parties (owner/GC/CM/JV, other subs, vendors, manufacturers, motorists). We pursue both tracks and resolve any comp lien.What’s the deadline to file?Most personal injury claims—including construction accident cases—carry a three-year statute of limitations. Don’t wait; job-site evidence disappears quickly.Who pays my medical bills now?Usually workers’ compensation benefits cover medical care first.

- Dorchester Truck Accident Lawyer for Serious Commercial Truck CrashesA crash with a commercial truck does not feel like an ordinary car accident. A tractor-trailer, semi-truck, box truck, dump truck, delivery truck, or other commercial vehicle can turn a normal drive through Boston into emergency surgery, months away from work, permanent pain, or a family loss that never should have happened. The first explanation is often too simple. Maybe the truck driver says traffic stopped suddenly. Maybe the trucking company points to the injured driver. Maybe an insurance adjuster calls before the family has even understood the injuries. Commercial truck crashes require a different kind of investigation. The driver matters, but so do the company behind the driver, the trailer, the dispatch records, the maintenance history, the electronic data, and the safety decisions made before the truck ever reached the road. Gavagan Law, LLC represents injured people and families in Dorchester, Boston, and throughout Massachusetts after serious truck crashes. If you are searching for a Dorchester truck accident lawyer after a tractor-trailer or commercial vehicle crash, the question is not only who hit whom. The question is what the trucking operation did, what evidence exists, and how quickly that evidence can be preserved.workplace injuries and work-related injuries.

A large truck needs more space to stop, more room to turn, and more time to react. When a driver or company ignores those realities, people in passenger vehicles, pedestrians, cyclists, and motorcyclists can pay the price. Common truck crash scenarios include: a tractor-trailer rear-ending traffic on I-93 or the Mass Pike a box truck turning across a lane in Boston traffic a semi-truck drifting into another lane because the driver is fatigued or distracted a truck making a wide right turn near a cyclist, pedestrian, or parked car a left-turn truck crash at an intersection an underride crash where a smaller vehicle goes beneath part of the trailer a multi-vehicle highway crash involving a commercial carrier a delivery truck crash in Dorchester, Cambridge, Quincy, Milton, Jamaica Plain, or another dense local area The crash report may describe the impact in a few lines. A real truck crash investigation looks deeper: speed, braking, lane position, sightlines, driver hours, dispatch pressure, maintenance, cargo, and whether the company put an unsafe truck or unsafe driver on the road. Those details matter because common causes of truck accidents often involve both driver conduct and company safety decisions. Commercial Trucks Are Different From Ordinary CarsThe central issue in many truck cases is not only size. It is the commercial operation behind the vehicle. The Federal Motor Carrier Safety Administration explains that large trucks and buses have unique safety challenges, including blind spots, wide turns, and long stopping distances. Those differences matter in Boston traffic. A truck driver moving through tight intersections, highway congestion, delivery routes, work zones, and neighborhood streets must account for the vehicle's limits. Several facts often shape the case: Trucks have large blind spots on multiple sides. A loaded truck can require far more distance to stop than a passenger car. Wide turns can put nearby vehicles, cyclists, and pedestrians at risk. Tractor-trailers maneuver differently from ordinary vehicles. Drivers must manage fatigue, distraction, route planning, braking, and traffic conditions. Trucking companies must decide who is qualified to drive, how loads are dispatched, and whether equipment is safe. That is why a commercial truck accident lawyer in Massachusetts must look beyond the moment of impact. A crash may reflect truck driver negligence. It may also reflect a company that ignored safety, pushed a schedule, failed to maintain equipment, hired the wrong driver, or failed to supervise. The Injuries Can Change Work, Family, and Daily LifeTruck crashes often involve forces that passenger vehicles were never built to absorb. The injuries can reach far beyond the emergency room. An injured person may need surgery for a shattered leg, shoulder, hip, or spine. A head injury may affect memory, sleep, mood, work, and family life. Internal injuries may not be obvious at the scene. Burns, scarring, nerve damage, amputations, and chronic pain can change how a person works, drives, sleeps, or cares for children. The financial pressure can arrive quickly. Medical bills, medical expenses, property damage, missed work, and long-term medical treatment can become part of the personal injury claim. Non-economic damages, including pain, loss of function, and emotional trauma, may also matter after severe injuries. For some families, the crash is fatal. Massachusetts wrongful death claims are governed in part by G.L. c. 229, and the claim is generally brought through the estate representative. The legal process should never reduce a death to paperwork. A serious truck accident wrongful death case often requires fast investigation into the driver, company, vehicle, trailer, dispatch decisions, maintenance history, and insurance coverage. Specific injury consequences matter more than labels. The case may turn on whether the injured person can return to work, whether future surgery is expected, whether the person needs long-term care, and how the injury changed the family's financial and emotional life. Trucking Company Safety FailuresMany trucking cases involve both driver negligence and corporate safety failures. A driver who is tired, distracted, poorly trained, or driving unsafe equipment did not appear on the road by accident. Someone hired that driver, assigned that route, dispatched that load, maintained that truck, or failed to enforce safety rules. Potential trucking company negligence can include: hiring a driver with an unsafe driving history failing to train or supervise the driver allowing hours-of-service violations or fatigue pressuring a driver to meet an unrealistic schedule failing to maintain the truck's brakes, tires, lights, mirrors, underride guards, or safety systems ignoring inspection problems overloading a trailer, allowing improper loading, or failing to secure cargo failing to enforce cell phone or distracted-driving policies failing to preserve or review safety data after prior incidents FMCSA materials identify driver qualification files and hours-of-service records as part of the commercial trucking safety system. Those federal laws and safety regulations are not background details. They can help show whether the trucking company treated safety as a real obligation or just a file to keep after the fact. Mechanical failures deserve close attention too. Brake failure, worn tires, ignored inspection reports, or missing maintenance records can be powerful evidence of negligence if the truck company knew, or should have known, that big rigs or other commercial trucks were unsafe. The page should not pretend every trucking regulation issue proves liability. It does not. But when a company fails to follow safety practices that exist to prevent crashes, those records can become important evidence. Truck Black Box, ECM, and Electronic EvidenceSome of the most important truck crash evidence may never appear in the police report. Modern commercial trucks can generate or store electronic information through the engine control module, electronic logging device, telematics system, GPS, dashcam, dispatch platform, or fleet-management software. FMCSA materials on ELD and hours-of-service records help show why this data can matter. Depending on the vehicle and system, electronic evidence may help show speed, braking, throttle, hours, location, movement, hard stops, route, driver status, or whether records were edited after the crash. Important details in truck accident litigation can include: ECM or black box data ELD records and driver logs telematics and GPS data dashcam or inward-facing camera footage dispatch and trip records maintenance and inspection records driver qualification files cell phone records cargo and loading records trailer ownership or leasing records post-crash company investigation materials This evidence must be preserved quickly. Trucks are repaired. Data can be overwritten. Dashcam footage may be deleted. Drivers may continue working. Companies may control the records before the injured person even knows those records exist. That timing problem is one of the reasons early legal representation matters in a serious commercial truck crash. What Gavagan Law Does in a Trucking CaseGavagan Law does not treat a commercial truck crash like a routine insurance claim or a simple motor vehicle accident. In a serious trucking case, the firm may move quickly to identify the trucking company, motor carrier, trailer owner, insurer, and any related companies involved in dispatch, maintenance, loading, leasing, or route planning. The goal is to understand the trucking operation, not just the driver named in the crash report. Depending on the case, Gavagan Law may: send preservation letters and spoliation notices request preservation of ECM, ELD, telematics, GPS, and dashcam evidence investigate the crash scene, roadway, sightlines, skid marks, debris, and vehicle positions identify witnesses and nearby video sources obtain police reports, law enforcement materials, medical records, wage records, and insurance information investigate driver qualification, training, fatigue, dispatch, maintenance, and inspection records examine trailer ownership, cargo loading, broker, shipper, and maintenance relationships work with accident reconstruction, trucking safety, medical, vocational, or economic experts where needed file suit when necessary to use subpoenas, written discovery, document requests, depositions, and sworn testimony identify all available insurance coverage, including commercial, excess, umbrella, cargo, leasing, or other applicable policies That work matters because trucking companies, large corporations, and insurers may have their own investigators, adjusters, and experts involved almost immediately. A serious truck crash case should not depend only on the version of events preserved by the company that may be legally responsible. What To Do After a Serious Truck Crash After a truck crash, the injured person may be in an ambulance, hospital, operating room, rehabilitation facility, or at home trying to understand medical bills and work restrictions. A family member may be the person gathering information. If it can be done safely, try to preserve: photos of the vehicles, roadway, skid marks, debris, traffic signals, signs, and surrounding area the truck number, company name, license plate, USDOT number, and trailer markings names and contact information for witnesses nearby business, traffic, dashcam, or surveillance video locations medical records, discharge paperwork, bills, prescriptions, therapy notes, and work restrictions any calls, letters, texts, or emails from the trucking company or insurer Avoid giving a broad recorded statement to a trucking insurer before understanding the issues. The company may already be analyzing driver conduct, vehicle data, and fault. Truck accident victims should not be pressured into answering questions before the evidence is preserved. The practical next step is to secure the evidence, understand the parties involved, and identify the insurance available for the injuries or loss. How Long Do You Have To File a Truck Accident Claim in Massachusetts?Many Massachusetts personal injury lawsuits must be filed within three years under M.G.L. c. 260, Section 2A. Truck crash cases can still require earlier action because evidence may disappear long before the legal deadline. Wrongful death claims have their own statutory framework under G.L. c. 229. Claims involving government vehicles, public entities, workers' compensation, minors, or other special circumstances may involve different notice or timing issues. Do not wait just because a deadline seems far away. In a trucking case, the most important deadlines may be practical: how long video is kept, how quickly electronic data is overwritten, when a truck is repaired, and whether the trucking company preserves records before they change.
