Lido

A complete operating record for a Grade II listed 1934 open-air seaside lido, kept by the charitable trust that runs it — the water, the plant that treats it, the listed structure that holds it, and the public that swims in it. The signature Water Chemistry Log is the statutory pool-water record sampled three times daily at the shallow end, the deep end and the balance tank: free and combined chlorine against the operating band, pH, total alkalinity, calcium hardness, cyanuric acid and turbidity, water and air temperature, bather load at the moment of sampling, and the corrective dose recorded against each out-of-band reading with the operator who made it. Behind it: the plant room as an isometric circulation circuit — balance tank, pumps on duty and standby, three sand filters with their backwash intervals and media age, the calcium hypochlorite and carbon dioxide dosing lines with drums in stock and days of cover, the heat exchanger and boiler with flow and return temperatures; bathing water sampling sent to the accredited laboratory with E. coli and intestinal enterococci counts against the intervention value, the resample chain and the notification duty; bather load and admissions with turnstile counts by session against the calculated maximum bathing load, the takings sheet by ticket class and the capacity margin flagged when it narrows; the lifeguard roster with the guard establishment set by the pool safety operating procedure, NPLQ qualification expiries, weekly drill records and incident reports written up to the emergency action plan; the heritage fabric register carrying the listed structure element by element — the Deco filtration tower, the terrazzo deck, the cantilever diving stage, the changing-cubicle terrace — each graded on condition, dated at last inspection, with its outstanding repair and estimated cost; consents and casework tracking listed building consent applications, the conditions attached and the correspondence with the local authority and the amenity society; the winter works programme costing the closed-season repair and repaint schedule against budget; and club and lane hire putting the swimming club, triathlon squad and school bookings on the lane timetable with the income each brings. Season-ticket holders get their own portal showing today's water temperature and chemistry, the session timetable, their swim history and their own ticket. Drawn entirely in the idiom of British interwar seaside modernism and the 1930s transport poster — deep marine navy against a pale bathing-blue band and cream paper, a single flare of lido orange, condensed Deco display capitals over a text serif, engraved hairline keylines, Roman-numeral datelines, and a hand-drawn isometric plant-room cutaway as the hero. Zero photography, zero gradients.

Turnstile

Turnstile is the statutory safety file of a sports ground — the record the ground safety officer and the local authority's Safety Advisory Group keep together, and the document that decides how many people may lawfully be admitted and exactly where they may stand. It opens on the general safety certificate itself: the issuing authority, the certificate number, the date of issue and the next review, and the conditions attached to it with a compliance status against each. Beneath that sits the calculation the whole file exists to defend. Authorised capacity is worked sector by sector from physical capacity, reduced by the (P) safety-management factor and the (S) physical-condition factor, and the ground total is the sum of those sector figures rather than a number typed in — so the fold's headline capacity, and the open, restricted and closed figures that partition it, are all derived from the sector register itself. The sector register carries every stand, tier and block with its seated or standing designation, its gangway and exit widths and its calculated figures. The exit and evacuation record holds exit routes, their widths and flow rates, and the calculated evacuation time against the eight-minute standard as well as emergency evacuation time to a place of safety. The turnstile and entry record tracks admission rates per hour, the counting system's status, and the reconciliation of counted admissions against the authorised sector figure fixture by fixture. Around those sit the stewarding plan with steward numbers required by ratio against numbers actually deployed, the inspection and test regime covering structural inspections, the annual engineer's report, barrier load tests and turnstile counting tests with pass or fail and retest dates, medical and first-aid provision against required ratios, the contingency plan register for fire, bomb threat, pitch incursion, power failure and adverse weather with last-rehearsed dates, an incident and near-miss log per fixture, and the Safety Advisory Group's own meeting record with attendees, actions and deadlines. A safety officer's portal shows the current fixture, the sectors open, the stewards deployed and the live admission reconciliation. Drawn in the lineage of British transport-authority signage engineering crossed with floodlit structural site-plan drafting — bitumen ground, chalk hairline linework, a drawn orthographic plan of the bowl whose sectors are state-filled, hazard-diagonal amber hatching on restricted sectors and a signal red reserved for the prohibited ones, dimension lines with end ticks annotating exit widths, and tabular figures throughout.

Touchline

Touchline is the match officials and safeguarding record of a sport's national governing body — the operational file kept by its referees committee and its safeguarding team, not a fan app and not a league table. The fold is the working appointments board for the current round: referee, two assistants and a fourth official against every fixture, with acceptance status, travel distance, conflict-of-interest checks against club affiliation and every unfilled slot flagged, over an availability window each official submits per round. Behind it sits the officials register — every registered referee, assistant and observer with registration number, level from grassroots entry up to the national list, region, registration status and expiry. Match reports and misconduct records cautions and dismissals per fixture against the disciplinary code, with each report timed against the forty-eight-hour submission deadline. Observation and assessment carries an observer's mark against a competency framework across control, positioning, application of law and management, a rolling average and a promotion or retention recommendation, feeding a season promotion list scored against published criteria. The fitness test register tracks the standard interval test, attempt, result and retest date beside the law examination record and in-service CPD attendance. The safeguarding file holds criminal-record check status and expiry per official, the mandatory safeguarding certificate and its renewal, the designated safeguarding officer, and a case register running referral, risk assessment, interim measures, outcome and review schedule, alongside a whistleblowing and concerns log. Expenses and match-fee claims run to an approval status. And the assault-on-officials register — the reason the whole file exists — records every incident of abuse directed at an official. Officials get their own portal showing their appointments, availability submission, rolling mark average and compliance status. Designed in the lineage of Dutch late-modernist grid systems crossed with the flat white linework of pitch markings — a deep cold pitch-green ground, chalk hairline geometry used as the structure of the layout itself, letterspaced condensed capitals, monospaced tabular figures, and colour reserved strictly for state: one chalk-yellow for caution, one deep red for dismissal and safeguarding escalation.
