Short answer: a crew can only start when the office work in front of it is done. Permits, material orders, client approvals and access bookings belong on the same plan as the site tasks they unlock, each with an owner, a date and a link to the work that waits on it.
Why do jobs stall between the office and the site?
Walk any small contractor's week and you see two lists. The site lead has the work: strip out, first fix, install, test. The office has a different list in a spreadsheet or an inbox: chase the permit, confirm the delivery, send the variation, book the lift. Nobody links the two, so the crew turns up on Monday and finds the materials are still at the supplier.
The research keeps pointing at that gap. In a February 2026 survey of 823 service technicians, the top things slowing them down were miscommunication between the field and the office (45%) and poor scheduling or last minute changes (44%) (ServiceTrade). A 2026 survey of 2,006 construction and design professionals across eight markets, including the US, UAE and Saudi Arabia, found 41% name poor communication and coordination as a leading cause of rework (Revizto). And UK and Irish teams told Procore and Dodge they lose about 18% of project time just searching for information (BDC Magazine).
None of that is a skills problem on site. It is a planning problem: the office tasks are invisible to the people who depend on them.
Which office tasks belong on the job plan?
Not every email. Only the office work that a site task cannot start without. On most jobs that is a short list:
| Office task | Site task it unlocks | Typical owner |
|---|---|---|
| Permit or approval submitted and received | Mobilisation | Project manager |
| Long lead materials ordered and confirmed | Install | Purchasing or estimator |
| Client signs off the layout or finishes | First fix | Project manager |
| Access, crane or lift booked | Delivery and lifting | Site coordinator |
| Variation agreed with the client | Extra work | Estimator |
| Test certificate and handover pack ready | Handover | Office admin |
If a line in that table slips, the site task after it slips too. That is why it belongs on the plan, not in someone's head.
How do you put both on one plan?
- List the site tasks first. Keep them at the level a foreman would use, such as "install outdoor units", not "HVAC".
- Add the office task in front of each one. Ask the crew lead one question: "What must be done before you can start this?" Write each answer down as its own task.
- Link them. The site task waits on the office task. When the order date moves, the install date moves with it, and everyone can see why.
- Give every task one named owner and a priority. "The office" does not chase a supplier. One named buyer does.
- Mark the dates the client sees as milestones. Handover, inspection and final invoice are the usual ones.
A small example: a rooftop AC replacement on a shop. The site work is four days. The office work in front of it, the landlord's approval, the unit order and the crane booking, takes three weeks. On one plan, the real start date is obvious on day one instead of a surprise on day twenty.
How do you keep it current every week?
- Review office tasks first in your weekly meeting. If the order or permit is late, the site plan is already wrong. Our 3-week lookahead guide walks through that meeting.
- Treat orders as tasks with dates, not notes. Our long lead items guide shows how.
- Update the plan the same day scope changes. A variation adds office work and site work together. See our change order guide.
- Find the chain that sets the finish date. Very often it runs through an office task. Our critical path guide explains how to spot it.
Where Zace fits
Zace is a project and task tracker built for construction, AC and solar jobs and the office work around them. You can lay out a job on a Gantt chart, add office and site tasks side by side, link them with dependencies so a late order pushes the install, set milestones for approvals and handover, and assign each task to a person with a priority. It runs on the web, Android and iOS, so the person at the desk and the person on the roof work from the same plan.
Frequently asked questions
Should office tasks really sit on the site schedule?
Yes, when a site task cannot start without them. Permits, orders, approvals and bookings set start dates as often as crews do, so they need dates and owners on the same plan.
Who should own the office tasks?
One named person per task, usually the project manager, estimator or office admin. Shared ownership means nobody chases it.
How detailed should the office tasks be?
Only as detailed as the site needs. One task per thing a crew waits on is enough. Everyday admin can stay off the plan.
