The kilometric chart is the official table the Trinidad and Tobago Defence Force uses to fix the road distance between every recognised residential area in the country and every recognised place of duty. It is the single source of truth for the distance value that appears on Form 26B and Form 26C.
Why distances are fixed in advance
The travelling allowance compensates members for the cost of commuting between home and work. If every member estimated their own distance, the allowance becomes impossible to audit — two members from the same neighbourhood reporting to the same camp would submit different numbers, and the cost would creep up over time.
The kilometric chart removes that variability. The distance between, say, “Arima” (area of claimant) and “Teteron Barracks” (place of duty) is the same value for every member, every month, until the chart itself is revised. The claim is then a simple multiplication: chart kilometres × the official mileage rate × number of trips.
How a lookup works
Every lookup needs two values from you:
- Area of claimant— the residential area where you live. This is the area as recognised by the chart, not your street address. Examples: Arima, San Juan, Diego Martin, Sangre Grande.
- Place of duty— the camp, base, or headquarters where you report. Examples: Camp Ogden, Teteron Barracks, Defence Force Headquarters, Camp Cumuto.
The chart returns a single number: the round-trip distance between those two endpoints. The travelling-claim line uses halfof that value per leg — a one-way distance — with To Duty and From Duty rows each carrying that one-way value, and a To-and-From row carrying the full round trip.
How AdminClaims.com uses the chart
AdminClaims.comimports the active chart into its database. When you set your area of claimant and place of duty on your profile, the wizard immediately looks up the one-way distance and previews it before you continue. The lookup is case-insensitive and tolerant of minor name variations — “St. Augustine”, “St Augustine”, and “Saint Augustine” all resolve to the same chart row.
The distance value is stored on the claim at submission time. That means a claim filed under the current chart will always read back the same distance, even if the chart is revised later — your historical claims won’t change retroactively.
When the chart doesn’t have your route
Two cases come up:
- Your area isn’t recognised— speak to your Company Office about getting your area added to the chart. The chart is revised periodically and new areas can be appended.
- Your place of duty isn’t standard— if you’ve been temporarily attached to a location that isn’t on the chart, AdminClaims.com lets you save a custom place of dutywith a one-way distance you enter once. The value is saved on your profile and reused on future claims so you don’t re-enter it.
When community-contributed distances exist for the same custom place, AdminClaims.com shows the median value as a non-binding suggestion. Final approval of any custom-place claim still rests with your HOD and Officer Commanding.
Chart versions
The Defence Force revises the chart occasionally to add new areas, correct distances, or adjust as new routes open.AdminClaims.com stores each revision as a separate version and uses the version that was active at submission time for every claim. Old claims display the distance they were submitted with, so audit history is preserved.
