Labour tracking for data-centre contractors
Data-centre programmes are the best fit in construction for norm-based labour tracking: identical halls, repetitive activities, and clients who expect CPI and SPI in the monthly report. WBSync tracks hours per hall and per activity against budgeted norms, so Hall 2's productivity calibrates the plan for Hall 6 — and the EVM pack the client wants falls out of the daily data.
A hyperscale fit-out repeats the same activities — containment, busway, power cabling, fibre, terminations, testing — hall after hall. That repetition is an opportunity: once you know your real hours per metre from the first hall, every later hall can be planned, resourced and bid sharper.
It only works if hours are captured per hall and per activity, not as one site-wide payroll number. WBSync structures the programme as Campus → Hall → Discipline → Activity and tracks earned against spent hours at each node, live.
Where the hours go on data-centre contractors packages
Hall-to-hall learning never gets captured
If Hall 1's overruns are buried in a site-wide total, Hall 4 inherits the same plan. Per-hall S/E turns the first halls into calibration data for the rest of the programme.
Clients demand EVM, spreadsheets deliver guesses
Hyperscaler and colo clients increasingly require SPI/CPI reporting. WBSync computes them to PMI / ISO 21508 conventions from approved hours and quantity-based progress — not from a hand-built monthly workbook.
Labour surges outrun the tracking
Crews can triple for energisation deadlines. Per-operative tracking with clock-in ingest and a daily approval gate keeps hours attributable even when 200 extra operatives land in a month.
Commissioning gates compress everything
Level 2–3 commissioning dates don't move, so late cable pulls cascade into overtime. A rolling look-ahead with at-risk flags shows which activities threaten the gate while there's still room to re-sequence.
L2 · Sub-location — Data Hall 03
L3 · Discipline — Electrical
L4 · Activity — Busway install & torque check (cost code DC2-H3-077)
How WBSync fits
Per-hall, per-activity earned value
Every hall is a WBS branch, so S/E (Spent vs Earned), SPI and CPI exist per hall, per discipline and per activity — and the S-curve shows planned value, earned value and actual cost for any branch you pick.
Client-ready EVM reporting
Progress reports with EV, AC, variances and forecasts (EAC, ETC, TCPI) generate as branded PDF or XLSX and can be emailed on a schedule — the monthly client pack without the monthly scramble.
High-volume clock-in ingest
Turnstile, biometric or app-based clock events stream in through vendor adapters or the open ingest API, then pass duplicate and 16h-per-day cap checks before approval.
Look-ahead against the baseline
Foremen plan the crew-day on the WBS; PMs get a rolling 1–6 week look-ahead with at-risk flags where planned work threatens the baseline — the early warning before a commissioning gate slips.
Frequently asked questions
Can we compare productivity across halls?
Yes — that's the natural shape of the WBS. Each hall is a branch, every activity carries budgeted and actual hours, and S/E per hall makes the comparison direct: Hall 3 at 0.92 against Hall 1's 1.04 is a conversation with evidence.
Our client requires monthly CPI/SPI — can WBSync produce it?
Yes. KPIs follow PMI / ISO 21508 conventions and the progress report exports EV, AC, SV, CV, SPI, CPI, EAC, ETC and TCPI as PDF or XLSX, with scheduled email delivery on paid tiers.
We peak at several hundred operatives — does pricing cope?
Tiers scale by active operatives (up to 800+ on Business and Enterprise), with operative packs to absorb mid-cycle surges and unlimited PM, engineer and foreman seats throughout.
Does it work in a hall with no signal?
Yes. The crew log is an offline-first PWA — entries queue on the device and sync idempotently when coverage returns, so a Faraday cage of a hall doesn't cost you the day's data.
