A sample access-control floor: sixteen openings, door hardware runs, and homeruns to the panel. Door D-104 still has an open conflict. After you create an account, open this set from Projects.

Hardware set HS-03 lists an electric strike. Spec and takeoff show a 1200 lb maglock with fire release. Leave the opening open until the architect answers — that is how a shop actually bids and hangs a door.

Pick a row to walk the job: bring the set in, take off the devices, set the scale, then issue the packet the field installs from.

Markup, split, sign, and organize drawings once they are in the workspace. Takeoff and field packets stay the main job.

Access-control and low-voltage firms, electricians, and service techs. The drawing stays the source of truth from estimate through as-built — takeoff, measured grid, cable, and field closeout on the same set.

Most jobs already live in Procore. Daily reports, pay apps, and RFIs to the GC stay there. Connect Procore to pull the issued drawings into this workspace. Takeoff, measured cable, and field closeout then happen in door marks and homeruns.

Same drawings for the people who bid, run, and hang the job. Estimators take counts off the sheet. Shop leads keep one current set. Electricians and service techs install from the issued packet.

Shops will not put a live set in a tool they cannot explain to the owner. Here is the short answer.

Built by Anthony Mrguru Feaster — locksmith for more than ten years, electrician apprentice, access control and low voltage. The packet is for people who hang the hardware.

Drawing Logic HQ works on phones, tablets, and desktops so estimators, project managers, electricians, service technicians, and shop admins stay on the same drawings.

RFI-01What is Drawing Logic HQ?

Drawing Logic HQ is a blueprint workspace for electricians, service technicians, and access-control and low-voltage contractors, operated by Ascendra Technologies. Teams upload construction drawings, run measured takeoffs, route cable on a scale grid, and coordinate field installation from one set.

RFI-02Who is this built for?

Electricians, service technicians, estimators, project managers, and field crews who need one current drawing for doors, hardware, devices, panels, and cable routes. Each shop's drawings stay in that shop. Teammates join by invitation.

RFI-03Why does the drawing stay the source of truth?

The sheet is already the contract. When the office traces a PDF twice and the field works from last week's print, the shop pays in rework and missed devices. Counts, routes, and as-builts stay attached to the current revision.

RFI-04Does it work on phones and tablets?

Yes. The workspace is built for phones, tablets, and desktops so office and field can open the same sheets.

RFI-05How do teams get started?

Create an account and confirm your email. Paid plans can create a workspace and start a trial immediately. Joining a workspace you did not create still needs an invitation or administrator approval.

RFI-06How does enterprise access work?

Drawings stay in the shop that owns them. Teammates join by invitation. Requests to join another shop wait for an administrator — typically within one business day. Security practices and a data processing agreement are public.

RFI-07Can technicians measure and snap to the sheet scale?

Yes. Set or approve the sheet scale, overlay a measured grid, and snap notes, devices, and cable runs to real-world spacing.

RFI-08Does this replace Procore?

No. The GC still issues drawings, RFIs, daily reports, and pay apps in Procore. Connect Procore to pull that set into your shop. Door marks, measured cable, and field closeout stay here.

RFI-09What is the Founding Field Program?

A small group of estimators, technicians, foremen, contractors, and blueprint readers who use Drawing Logic HQ on real work and tell us what helps, what slows them down, and what is missing.
