Sebastian Di Poi Enterprises Inc. is a computer systems design practice in Ottawa, working from 511 Lacolle Way, Ottawa - K4A 5B6, Canada (CA). We take the tangled middle of an integrated technology project, lay it flat on a drafting table, and return it as a set of readable sheets that engineers, contractors and permitting offices can act on. The work is quiet, measured and documented, and it always begins with a drawing.
See the six drafting servicesEvery project hangs from one rail of numbered sheets. A sheet that is not on the rail is not issued, and a sheet that is issued has a revision mark on its face.
The parallel bar is the practice, not the decoration. Lines that must stay true are drawn against a straight edge, checked twice and dated once.
Four grades for four jobs: sketch the idea, weight the line, shade the connection, and leave a note in the margin for the person who builds it.
Most technology failures are not failures of hardware. They are failures of layout. A camera that cannot reach its recorder, a rack that does not fit behind the wall, a data outlet drawn in a lift shaft, a renovation that closes a corridor a technician still needs on a Monday morning. Sebastian Di Poi Enterprises Inc. exists to reduce that failure rate by treating systems the way a good building is treated: drawn first, questioned on paper, issued with a revision letter.
We work in the space between the building trades and the systems integrators. On a typical week the drafting table holds a low voltage plan for an office fit out, a corrections set returned by an electrical reviewer, a riser diagram for a small college campus and a sheaf of as-built notes from a job that closed two years ago and never got its final drawings. These are not glamorous artefacts, but they are the ones that keep a site moving and a building inspector signing.
The practice is deliberately small. One senior eye reviews every sheet, and the same person who answers the telephone at 511 Lacolle Way, Ottawa - K4A 5B6, Canada (CA) is the person who signs the title block. You can call the studio on +15075807626 and reach a human rather than a queue.
The sheets are cut to different widths on purpose. Projects are not uniform and neither are our drawings.
We draw the ground floor and the yard around it, with the system routes made visible against pavement, planting and property line. Cable trenches, camera sight lines, equipment pads and service entry points are drafted to scale, then checked against the municipal survey before anything is issued.
Site plan details →When a tenant changes a floor, the systems have to change with it. We produce the full layout set that shows new partitions, relocated outlets, ceiling device positions and the routes that survive the move.
Renovation sets →A permit package is a conversation with a reviewer you will never meet. We assemble cover sheets, notes, plan views, risers and schedules into one clean submission sequence, with every reference resolution correct and every note traceable to a code clause.
Permit packages →Field reality never matches the issued set. We take red line markups, photographs and site notes, then correct the original drawings to reflect what was actually installed, complete with a clear revision cloud and date.
As-built corrections →Riser diagrams are the spine of an integrated building. We map conduits, head end equipment, amplifiers, network switches and power sources into a single vertical story that a technician can follow from basement to roof.
Riser diagram runs →At the end of a project, small things decide whether the building opens. We draw quick, precise punch list sketches that show exactly which device, which wall and which mount needs attention, so a tradesperson can act without a site visit.
Punch list sketches →A drawing set is not a stack of pretty plans. It is an argument. Each sheet states a position, and the next sheet has to agree with it. When a client sends us a scope, we start by reading it against the existing conditions, the building survey and the equipment cut sheets. Where those three sources disagree, we mark the disagreement before we draw anything new.
The drafting table then runs in three passes. The first pass is a light line layout where sizes, routes and equipment positions are settled. The second pass weights the line, adds notes and annotations, and checks every callout against the plan it points to. The third pass is a cold read, where a second reviewer opens the set as though seeing it for the first time and marks anything that would confuse a contractor. Only after that does a sheet receive its issue stamp.
Field survey, service records and equipment data are reviewed together before a single new line is committed to the sheet.
Line weight carries meaning. A heavy line is a decision, a light line is a possibility, and a construction line is removed before issue.
This is slower than pushing rectangles into a template, and it is why our sets tend to come back with fewer review comments. When a reviewer asks why a conduit turns where it turns, the answer is already on the sheet in a note. When an installer asks where the amplifier goes, the riser diagram has the rack elevation and the circuit number.
We are happy to work inside another consultant s sheet standard, or to bring our own. What we will not do is issue a drawing that we cannot defend line by line.
Sebastian Di Poi Enterprises Inc. works in the computer systems design and related services sector, and specifically in computer integrated systems design. In practice that means we are usually the drawing office beside a specialist contractor: the people who install access control, audio visual, structured cabling and security systems often know exactly what they want to install but lack the documentation to communicate it.
Our drawings close that gap. A site plan drafting sheet tells the civil contractor where a bollard-mounted reader will stand. A renovation layout set tells the tenant coordinator which ceiling grid will now carry a wireless access point. A permit drawing package gives the reviewer a complete, consistent story. An as-built correction makes the record match the building, which matters when the next renovation arrives five years later and the drawings are handed to a stranger.
All of these are ordinary starting points. The drafting table does not care where a project begins as long as the first move is to get the facts onto paper in the right order. That ordering, we argue, is the real product.
A drawing is only useful if the next person can trust it. These are the habits we hold to on every commission, whether it is a single punch list sketch or a full permit submission.
Project number, sheet number, revision letter, date and drafter initials live in one place and are updated together. A sheet never leaves the table with a mismatched title.
Every plan carries a printed scale bar so it survives photocopying, scanning and the inevitable screenshot.
General notes carry consistent numbers across a set so that reviewer comments can cite them precisely and contractors can ask about them directly.
Changed areas are clouded, marked with a revision letter and dated. Older versions stay in the archive so the project history remains legible.
A callout to sheet 05 or detail D3 must actually exist. We run a reference check before any package is issued.
Layer names are plain and readable. Anyone opening the digital file should be able to find the walls, the devices and the hatching without a legend.
The process is short because the table is small. Most commissions move from first call to first issue in two to four weeks, with full permit packages on a longer clock.
We collect the building survey, existing drawings, scope and equipment data, then write down the open questions before drawing begins.
A light line layout settles positions, routes and sheet order. You review this before any heavy line is committed.
Notes, callouts, schedules and risers are added and checked against each other. A second reviewer performs a cold read.
The set is stamped, archived and handed over, with a red line copy for the field and a clear date for the next revision.
The studio at 511 Lacolle Way, Ottawa - K4A 5B6, Canada (CA) still has a physical drafting table in it. There is a blueprint rail on the wall with the sheets of live projects hanging from it by their tag holes, a parallel bar that gets oiled more often than it needs to be, and a pencil tray that has never once held the right grades in the right order. That table is the reason this website looks the way it does.
We mention it not for nostalgia but because the metaphor disciplines the practice. A draftsperson cannot pretend a plan is finished when a callout points at nothing. The same is true of an integrated systems project. A camera schedule that does not match the floor plan is not finished. A riser diagram that skips the mid floor cabinet is not finished. The drawer is a reminder that a set is only done when every line agrees.
