Inspections glossary: vehicle, property and asset

100 percent inspection is the examination of every item in a batch against the acceptance criteria instead of a sample, so each unit is individually judged conforming or nonconforming before release. It is used where one escaped defect is unacceptable, and it is less reliable than the name suggests.

Accredited inspection is inspection performed by a body whose competence, impartiality and consistency have been assessed by an independent national accreditation body against a published standard, normally ISO/IEC 17020. Accreditation is a judgement about the inspector, not about any single result.

An annual inspection is a full condition and compliance check carried out once every twelve months, usually because a regulator, an insurer, or an internal standard requires it on that cycle. It certifies a state on a date rather than monitoring an asset over time.

A borescope inspection is a remote visual inspection of the inside of a machine, vessel or structure, carried out by passing a rigid or flexible optical probe through an existing access port. It exists because the alternative, stripping the item down to look, is expensive.

A building survey is a detailed inspection of a property's construction and condition by a chartered surveyor, reporting on defects, their likely causes, the repairs required, and what happens if they are left. It is the most thorough of the standard survey types, commissioned before a purchase or a lease.

A check-in report records the condition, cleanliness and contents of a rented property on the day the tenant takes occupation, signed or acknowledged by the tenant. It is the baseline every later deposit deduction is measured against, which makes it the most consequential document in the tenancy.

A check-out report records the condition, cleanliness and contents of a rented property at the end of a tenancy and compares them line by line against the check-in report. It is the document a deposit scheme adjudicator reads first when a landlord claims a deduction.

A collection inspection is the condition record made at the point an asset is picked up, either by a carrier taking it away or by an owner recovering it at the end of a contract. It sets the baseline for the movement that follows and decides where a carrier's liability starts.

Condition grading is the practice of summarising an asset's physical state as a single value on a defined scale, so that different inspectors describing the same asset arrive at the same answer. The grade is a shorthand for an agreed set of observations, not an opinion about the asset.

A confined space inspection is an examination of a space that is enclosed or largely enclosed and carries a reasonably foreseeable risk of serious injury from conditions inside it, such as a tank, silo, sewer, flue or pit, where entering to look is itself the most dangerous part of the task.

A damage inspection is a condition check triggered by a specific event: an impact, a leak, a fall, a storm. It records what was damaged, how badly, and where the damage sits, so that someone who was not standing there can decide what happens next.

A damage matrix is the grid an operator uses to turn observed damage into a consistent code and a charge: panel or component down one axis, damage type and severity across the other, with a tolerance and a cost in each cell. It is what makes two inspectors reach the same number.

A damp survey is a professional inspection carried out to establish where moisture in a building is coming from, how it is moving, and what will stop it. A competent damp survey identifies the cause, not just the symptom, and is carried out by someone with no financial interest in the remedial work.

Defect classification is the practice of sorting inspection findings into severity classes, conventionally critical, major and minor, so that what happens next is driven by the seriousness of the fault rather than by who happened to write it up.

Dilapidations are the breaches of a commercial tenant's lease obligations to repair, decorate, and reinstate a property, together with the money claim a landlord brings to put those breaches right. In England and Wales the end-of-lease remedy is damages, not an order to carry out the work.

A drone inspection is a remote visual or sensor-based inspection carried out from an uncrewed aircraft, used to reach height, water or access-restricted structures without putting a person there. It gathers data for assessment. It does not replace the assessment itself.

A DVIR, the driver vehicle inspection report, is the written report a driver of a commercial motor vehicle in the United States completes at the end of each day's work, listing any defect that would affect safe operation or is likely to cause a breakdown. The carrier must repair or certify each listed defect before the vehicle is driven again.

An end of lease inspection is the formal condition assessment carried out when a leased vehicle is returned, grading bodywork, glass, tyres, interior, equipment and paperwork against the return standard written into the contract. It produces the report that end-of-contract charges are built from.

Fair wear and tear is the deterioration a vehicle picks up through normal, careful use over the term of a lease, as opposed to damage caused by a specific event, neglect, or misuse. It is the line every end-of-contract charge is argued across.

Final inspection is the last conformity check carried out on a product or a completed job before it is released to the customer, verifying against the full set of acceptance criteria that everything the specification requires has been done, verified and recorded.

A hire agreement is the contract by which an owner lets a hirer take possession and use of plant, equipment, or a vehicle for a period in return for hire charges, keeping ownership throughout. In UK plant and tool hire it is the standard term for what vehicle and US markets call a rental agreement.

Incoming goods inspection is the conformity check carried out on materials, components or finished products at the point of receipt, before they are booked into stock or released to production, to confirm that what arrived matches what was ordered and meets the agreed specification.

In process inspection is the checking of work while it is still in production, at defined points between operations, so that a nonconformity is found and corrected before more value is added to the part or before a later operation buries the evidence.

An inspection audit is a re-examination of a sample of completed inspections, carried out to establish whether the work behind the records really happened and whether the judgements recorded in them were sound. It is the check on the checkers: it inspects the inspection records rather than the assets.

An inspection backlog is the set of inspections past their due date and not yet completed, measured by both count and age. The count alone says very little. Nine items three days late and nine items nine months late describe two completely different estates.

Inspection bias is any systematic influence that pushes an inspection result away from the condition of the item and toward something else: the previous result, the answer the inspector expects, the time of day, or the inspector's own stake in the outcome. Systematic is the key word.

An inspection checklist is a structured list of items an inspector must check during a single inspection, in a fixed order, with a recorded outcome for each item. It turns a procedure into a sequence of prompts, so completeness does not depend on what the inspector happens to remember that day.

Inspection completion rate is the share of required inspections that were actually carried out in a given period, calculated as inspections completed divided by inspections required. It is also the easiest inspection metric to hit dishonestly, because closing a record counts the same as inspecting an asset.

Inspection coverage is the share of the required inspection population that was actually inspected to standard within a defined period, expressed as a percentage. It answers one question: of everything that had to be examined this period, how much of it was.

Inspection criteria are the stated standards each item in an inspection is judged against, expressed precisely enough that two competent inspectors reach the same conclusion. They answer what good looks like, which is a separate question from what gets examined.

Inspection cycle time is the total elapsed time between an inspection being requested and a usable report being available to act on, counted in calendar time across the whole process rather than in working hours anyone spent on it. It splits into four segments, and the dominant one is rarely the one teams try to fix.

Inspection frequency is how often a given asset is formally examined, expressed either as a fixed calendar interval or as an interval derived from risk, usage and failure history. It is set per asset class rather than per fleet, and statutory duties override whatever the operator would otherwise choose.

An inspection interval is the elapsed time, running hours or usage cycles permitted between one completed inspection of an asset and the next. It is set per asset rather than per fleet, and every due date in a schedule is simply the last completed date plus the interval.

An inspection report is the issued document stating what was inspected, when, by whom, against which criteria and what was found, written so that someone who was not present can rely on it later. It is the output of an inspection, not the working notes behind it.

Inspection scheduling is the work of assigning every due inspection to a date, a competent inspector and a location, so each asset is examined before its interval expires. It does not change how much work exists. It only decides whether that work gets done in time.

Inspection scope is the defined boundary of what a given inspection covers: which items, which characteristics, at what level of access, at what point in time. Everything outside that boundary is not a pass, and it is not a fail. It was simply never examined.

An inspection sign off is the act of a named, authorised person attaching their identity to an inspection record and stating what they will stand behind. It is the point where a set of observations becomes somebody's professional assertion rather than a collection of files.

An inspection standard is a published document that defines what an inspection covers, how it is carried out and what counts as a pass or a fail, so that two competent inspectors applying it to the same item should reach the same result. It fixes the meaning of good before anyone looks.

Inspector competence is the demonstrated ability of a person to carry out a defined inspection correctly and consistently, combining training, knowledge, skill and experience with the judgement to apply them to the item in front of them. A certificate records training. Competence shows up in the work.

An inventory clerk is an independent professional who documents the condition and contents of a rented property, producing the inventory and check-in report at the start of a tenancy and the check-out report at the end, without acting in the interest of either the landlord or the tenant.

An inventory report, in lettings, is the itemised record of everything in a rental property and the condition of each item, room and surface at the start of a tenancy, supported by dated photos. It is checked and signed at check-in, compared at check-out, and is the main evidence a deposit scheme uses to decide deductions.

Lettings inventory software is the tooling inventory clerks and letting agents use to produce the inventory and schedule of condition at the start of a tenancy, the mid-term inspection and the check-out report at the end, with dated photographs embedded in each report and the tenant's agreement recorded. It is also called property inventory software.

A lighting check is a capture-quality control that tests whether there is enough usable light on the subject before or during recording, so the person reviewing the result later can tell what is actually in the frame. Too dark, blown out or lit from the wrong side, and the step is flagged for a redo.

A mid-tenancy inspection is a scheduled visit by a landlord or agent during a tenancy, typically every three to six months, to check the property is being looked after and to catch maintenance problems such as damp, leaks or faulty alarms early. It is carried out with written notice and recorded with dated photos.

A mid term inspection is a condition check scheduled partway through a contract, tenancy, or service interval rather than at its start or end. Its purpose is to surface problems while there is still time and contractual room to act on them cheaply.

A move-in inspection is the walk-through of a rental property at the start of a tenancy, recording the condition of every room, fixture and fitting with dated photos and notes that landlord and tenant both sign. It is the baseline the move-out inspection is compared against. In the UK and Ireland the same record is called a check-in report.

A move-out inspection is the walk-through of a rental property when the tenant leaves, comparing its condition against the move-in record to establish what has changed, what counts as fair wear and tear, and what may be deducted from the deposit. In the UK and Ireland it is called a check-out report.

Non destructive testing (NDT) is a family of inspection methods that assess the condition, integrity or properties of a material or component without damaging it or taking it permanently out of service. The item is still usable after the test, which is the whole point of the discipline.

An odometer reading is the distance figure shown on a vehicle's odometer at a specific moment, recorded with a date so it can be compared against earlier readings. A single reading is a data point about a display. The sequence of readings over time is what tells you whether to trust it.

Off hire is the point at which a hirer notifies the owner that hired plant or equipment is finished with and available for collection, ending the charging period. It is one of the most disputed moments in hire, because collection usually happens later than the notification.

On hire is the status of an asset that has been released to a hirer and is accruing hire charges, running from the moment it leaves the owner's control until it is formally off hired. It is also the point at which condition should be recorded, because that record sets the standard the asset is judged against on return.

Pass fail criteria are the rules that convert an inspection measurement or observation into a binary verdict: this item is accepted, or it is rejected. They sit downstream of the standard itself, and they are where a measured value becomes an operational decision.

A post hire inspection is the condition check carried out when a hired asset comes back, set against the pre hire record to identify what changed during the hire. It is not an assessment of condition. It is a comparison, and it fails whenever the two records were shot differently.

A pre hire inspection is the condition record taken of an asset immediately before it is released to a hirer, signed by both sides. It does nothing on the day it is made. It is the baseline every later damage claim gets measured against, and no charge survives without it.

A pre purchase inspection, or PPI, is a condition check commissioned before a buying decision by the party carrying the risk of that decision. It reports the state of the asset at one point in time so the buyer can proceed, renegotiate, or walk away.

A pre start check is the inspection an operator or driver carries out before a vehicle or machine is used, covering safety critical items that can be checked without dismantling anything, with every defect found reported and recorded before the asset is put to work.

A pre-trip inspection is the check a driver carries out on a vehicle before starting a journey to be satisfied it is in safe operating condition. In the United States it is a duty under 49 CFR 396.13; in the UK and Ireland the equivalent is the daily walkaround check before first use.

A property inspection is a documented visual check of a rented property's condition, carried out by a landlord, letting agent or inventory clerk at a set point in the tenancy. It records the state of the building, its fixtures and its contents on a specific, evidenced date.

A re-inspection is a repeat examination of an asset already inspected once, carried out either to verify that a failed item has been properly remedied, or to redo an inspection whose evidence was unusable. The two look identical on a schedule and mean very different things.

Remote inspection is the umbrella term for any process in which a vehicle, property, machine or site is assessed without the assessor travelling to it, covering live video sessions, guided self capture, drone and sensor methods, and desk review of submitted material.

Remote video inspection is an assessment carried out by an expert who is not at the location, using video captured by someone who is standing in front of it. In most industry usage the term means the live variant, with the assessor watching and directing the camera in real time.

A rental agreement is the contract under which an owner gives a customer temporary possession and use of an asset for an agreed period and price, while keeping ownership of it. It settles three things that decide almost every later argument: permitted use, what gets paid, and who carries the cost of damage.

A roof inspection is an examination of a roof covering and everything around it, including flashings, rooflights, gutters, outlets, fixings and rooftop plant, carried out to record condition, locate defects and water ingress, and decide what repair work is needed and how urgently.

Sample inspection is the practice of checking a defined random subset of a lot and using that result to accept or reject the whole lot. The sample size and the number of nonconforming items allowed come from a published sampling plan, not from the inspector's judgement on the day.

A schedule of condition is a dated factual record, written and photographic, of the state of a building at a fixed moment, normally the start of a commercial lease. Annexed to the lease and referred to in the repairing covenant, it limits the tenant to leaving the property in no worse condition than the record shows.

A second opinion inspection is a fresh inspection of the same asset by a different qualified inspector, carried out to test the first inspector's conclusion. It is usually triggered by a dispute, a high-value decision, or a result that looks out of line with expectation.

A security deposit is money an operator takes or blocks at the start of a rental or hire as protection against unpaid charges, fines, and damage. In vehicle rental it is usually a card pre-authorisation rather than a payment, and it is released once the account is settled.

Self service inspection is any inspection in which the person already at the location completes it unaccompanied, with no inspector, adjuster or engineer attending in person or watching live. The organisation sends the request, and whoever is there does the capturing.

A severity rating is a scored judgement of how serious a defect is, placed on a defined scale so the same fault, recorded by different people on different days, lands in the same band and triggers the same response. It ranks consequence, not likelihood.

A snagging app is software used to record defects on a new-build or newly fitted property, one item at a time, each with a photo, a location, a description and a status, so the builder can put every item right and the buyer can see it closed. In the US it is called a punch list app.

A snagging inspection is the systematic check of a newly built or newly refurbished property for defects, unfinished work and departures from specification, carried out before or shortly after handover so the builder can put them right. The output is the snagging list; the inspection is the process that produces it.

A spot check is an unannounced inspection of a small number of items drawn from a larger population, used to test whether the routine process is working. It is triggered by suspicion or by a sampling plan rather than by an event or a date in the calendar.

A tenancy deposit is money a tenant pays a landlord or letting agent at the start of a tenancy as security against unpaid rent, damage or cleaning costs. In England and Wales it must be held in a government-approved protection scheme and returned in full at the end unless the landlord can evidence a deduction.

A tenant inspection app is a tool that lets the tenant, rather than an agent or inventory clerk, record the condition of a property on their own phone at check-in, mid-tenancy or check-out. The landlord or agent sets what has to be photographed, and the tenant's submission becomes the dated condition record.

A thermographic inspection uses an infrared camera to map the thermal radiation leaving a surface, so that a condition beneath or behind that surface can be inferred from the pattern. It measures surface temperature. It does not see through anything.

An underbody inspection is a structured examination of the underside of a vehicle or machine, covering chassis, suspension, brake and fuel lines, exhaust, driveline and corrosion, carried out from an inspection pit, on a vehicle lift, or with the asset raised and supported on stands.

A used car inspection is a structured condition check of a used vehicle against a defined checklist, recording identity, mileage, mechanical condition, safety items, bodywork and interior. It establishes what state a car is in, without saying anything about what it is worth.

A vehicle condition report, usually shortened to VCR, is a structured record of a vehicle's physical and mechanical state at one point in time: panel by panel, with photographs, declared damage and often a numeric grade. It is the document every sight-unseen vehicle transaction is priced against.

A vehicle appraisal is a formal assessment of what a vehicle is worth at a given moment, based on its identity, specification, mileage, condition and the live market for that exact unit. It is the general act of valuing a car, whatever the reason the valuation is needed.

A virtual inspection is an assessment of an object, vehicle, property or site carried out through video and images instead of in person. In most industry usage the term points at the live variant, where an expert joins a video session while someone on site moves the camera.

Visual inspection is the examination of a component, structure or asset by eye, unaided or with optical aids, to detect surface conditions such as cracks, corrosion, leaks, distortion and missing parts, judged against defined acceptance criteria. It is the oldest inspection method and still the most used one.

A working at height inspection means one of two things: an inspection task carried out where a person could fall a distance liable to cause injury, or the inspection of the equipment and places used for such work, including scaffolds, working platforms, ladders and edge protection. Both carry duties.
