A practical starting point

Start with one repeatable workflow.

01

Define the workload

Share the backlog, templates, deadlines, and people involved. Agree on the tasks, review points, and escalation rules.

02

Work in your process

A dedicated team member follows your folder structure, tools, and communication channels. Your team retains approval authority.

03

Review visible output

Receive current registers and a weekly list of completed tasks, overdue items, and decisions needed from your team.

Representative deliverable

One record for open items and next actions.

A project-control log brings RFIs, submittals, changes, responsible people, and due dates into a shared view. This illustrative sample shows the kind of record we can maintain; it contains example data, not a client's project information.

Office support questions

A dedicated person behind your office workflow.

Define the responsibility, review the output, and keep control of decisions.

What is needed for an office-support proposal?

Share the recurring workload, backlog, tools, templates, deadlines, and review contacts. We agree the tasks, working registers, reporting rhythm, access permissions, approval points, and pricing before the assignment begins.

What does subcontractor office support include?

Office support can include bid administration, RFI and submittal tracking, drawing records, vendor follow-ups, invoice tracking, timesheet checks, and project-status reporting. The exact tasks and review points are agreed before work begins.

Can we start with one task rather than our whole back office?

Yes. Start with a defined workflow, such as a bid register, submittal log, or invoice tracker. Agree on the handoff, turnaround expectations, and approval process before adding more responsibilities.

Will the same person work in our tools?

ModelMason assigns a dedicated team member who learns your templates, folders, naming conventions, and communication channels. Tool access and permissions are agreed with your team.

Who approves pricing, payments, and project commitments?

Your authorized team retains approval of pricing, payments, payroll, contractual commitments, and technical decisions. ModelMason prepares and tracks the assigned information for your review.
