Construction Subcontractor Portal Development

Alpha ExpansionConstruction companies
In short

A subcontractor portal gives every trade on a project one place to receive the current drawings, send submittals for approval and see what has been decided. Each company sees only the packages it works on. Each document carries its revision and its status, so nobody builds from a superseded drawing or wonders whether a submittal was approved, returned or is still with the consultant.

Key points
  • 01Subcontractors see their own packages and nothing belonging to other trades.
  • 02A drawing has one current revision, and older ones are clearly marked.
  • 03Each submittal shows who holds it now and how long they have had it.

The main workflow, step by step

Below, one submittal goes from a subcontractor to an approved document on site. Choose a step to look at its screen. The project, the companies and the document numbers are invented for the demonstration.

Off the pathWhen a drawing is revised later, everyone who downloaded the earlier one is told which document replaced it.

02

Who uses it, and what each role can do

A project brings together companies that must share documents without sharing everything. Permissions follow the project and the package, not the person's employer alone.

RoleSeesCan do
Subcontractor userDocuments and submittals for their packagesDownload current documents, submit and resubmit
Site engineerAll packages on their projectCheck, return or forward submittals and issue documents
Consultant reviewerSubmittals routed to their disciplineApprove, comment or ask for revision, per sheet
Project managerEvery submittal, its holder and its ageReassign, escalate and report to the client
Document controllerThe register of drawings and revisionsIssue revisions, supersede and manage distribution
03

When the work leaves the usual path

Disputes on site often trace back to a document question. These situations are handled inside the portal, so the answer is on record when it is needed later.

What it connects to

Contractors already hold drawings and programmes in other tools. The portal connects to them where that saves double entry, and stands alone where it does not.

What a first release includes

01

Projects and packages

Projects divided into work packages, with companies and people given access package by package.

02

Drawing register

Documents with revisions, status and distribution, and a clear mark on anything superseded.

03

Submittal workflow

Submission, first check, consultant review per sheet, comments and resubmission, with review periods tracked.

04

Status at a glance

A view of every open submittal showing its holder and age, for the weekly project meeting.

05

Notices that matter

Messages when something needs a person's action or when a document they rely on has changed.

06

Record for handover

The full history of what was submitted, approved and issued, exportable at the end of the project.

Often added after the first release

  • Requests for information on the same record
  • Site instructions and variations
  • Subcontractor insurance and qualification documents
  • Mark-up and comments on drawings in the browser
  • Progress photos linked to packages
06

What we need from you

  • A current project's submittal log and drawing register, in whatever form they exist
  • Your review stages and the review periods in your contracts
  • How packages are divided and which companies see what
  • The document tool you use now, and access to a test area in it
  • A document controller and a site engineer to test with real submittals

Ownership and licensing terms are defined in the project agreement.

07

What to do next

Send us the submittal log from one live project. It tells us how many documents move, how long they wait and where, and we reply with a suggested scope and a proposal. Start a conversation or book a 30-minute call.

08

Common questions

How is this different from a construction management suite?

The large suites cover far more ground, from tendering to cost control, and suit contractors who will adopt the whole product. A custom portal makes sense when you need one part done your way, when subcontractors resist a tool that requires licences and training, or when it has to fit systems you already run. We compare the options honestly before recommending a build.

Do subcontractors have to pay or install anything?

No. They receive an invitation, sign in through a browser on a computer or a phone and see only their packages. Nothing is installed and no licence is needed on their side. That matters, because a portal only works if the smallest trade on the project uses it. The interface for them is deliberately limited to a few clear actions.

Can consultants outside our company take part?

Yes. External reviewers are invited to the project with a role that shows them only the submittals routed to their discipline. They can respond in the portal or, if they insist on email, a site engineer can record their response on the submittal. Either way the status, the comments and the dates are kept on one record.

What happens to the records when the project ends?

The documents and their history can be exported in full for the handover file and for your archive. How long they are kept, and where, follows your contracts and policies. Subcontractor access ends with their involvement, while the record of what they submitted remains. Hosting and administration after the project are settled in the project agreement.
