V8 / Value — Lead Architect (Client-Side)
The building that arrives should be the building that was drawnDesign intent, held.
RFI thread indexed against the drawing register. Deviation log surfaced the moment a substitution enters the record — not six months later at handover. Design-intent-as-data: every approved change, every silent departure, every pending opinion. Solene's job is to hold the line between what was drawn and what is being built — and Loadbearer is the system that makes the line visible.
Solene opens Loadbearer at 07:45 and already knows which RFIs are in scope, which substitutions are pending an opinion, and which deviations have been built without one.
The client-side architect never has time to look at what was drawn — they spend it chasing what has changed. Loadbearer surfaces the morning's picture before Solene boards the train from Wandsworth: which RFIs crossed the SLA overnight, which deviation reports are awaiting her impact statement, which specification substitutions are moving through the contractor's system without being copied to her. The record writes; Marchetti reads, judges, responds.
Design intent vs site reality · the gap that opens in silence
The drawings are not the building. Loadbearer is the thread between them.
At 07:45 on a Tuesday, Solene Marchetti opens her laptop in Wandsworth and finds RFI-2847 in her inbox. Marauder are requesting approval to substitute the specified insulated metal panel — a through-colour dark bronze, long lead — with a "visually equivalent" panel from a different manufacturer. The RFI has already been through two rounds. The first round went to the contractor's design manager. The second went to the M&E coordinator. At no point in either round was the architect copied. The decision was nearly made — in writing, on the record — without the person whose drawing specified the panel.
That is the shape of Solene's professional life. She is employed by Phoenix Digital — the client — not by the design firm. Her role is to custody the design intent on the employer's behalf: she signs off design changes, manages the RFI thread as it relates to architectural matters, and maintains the golden thread from issue-for-construction through to as-built. She does not author the drawings; she holds the line between what they require and what the contractor builds. The gap between those two things opens quietly, in small decisions, across 54 pods, three halls, and 340 million pounds of construction.
By handover, the building looks roughly like the design. But the soul has leaked out in a thousand small substitutions — a panel here, a door ironmongery set there, a louvre orientation changed because the plant room coordination moved, a fire-stopping detail interpreted differently on Hall 2 than Hall 1 because the RFI that would have caught it was never routed to the architect. Loadbearer does not prevent substitutions. It makes them visible — every one of them, at the moment they enter the record, with a named owner and a decision required.
What Loadbearer eliminates
- The RFI that cycles through two contractor-side review rounds without the architect being copied — and very nearly becomes a built decision.
- The substitution request described as "visually equivalent" in the covering note, where the deviation from specification is buried in page four of the attachment.
- The deviation register maintained by the contractor in a spreadsheet that Marchetti receives as a Friday attachment — reconstructed, not live.
- The as-built drawing package assembled at handover that documents where the building ended up — with no trace of when each departure from design intent was made or by whom.
- The fire-stopping detail that was built differently across two halls because the design clarification was given verbally on site and never entered the record.
- The three-hour Monday morning spent reconciling the contractor's RFI log against her own tracker to find the items requiring an architectural opinion this week.
- The design change that crossed the client-approval threshold without Krupa being notified, because the commercial event was not connected to the design event in any system.
What Loadbearer surfaces
- Every RFI with an architectural scope, routed to Marchetti at the moment it enters the system — not after contractor-side rounds have narrowed the options.
- The deviation register, live: every departure from specification, every substitution request, every site-raised TQ with a design implication — indexed against the drawing it touches.
- Substitution audit trail: who requested it, on what date, against which drawing revision, with what justification, and what Marchetti's opinion was — or that her opinion is still outstanding.
- RFI SLA clock: five-day default, visible from day one, escalated to Krupa at breach — not discovered at the next design review meeting.
- Design-intent-as-data: the golden thread from IFC issue through every approved change to the current as-built position — one query, not a binder assembly.
- Penetrations and firestopping: per-zone RAG, open sign-offs, and the detail variants that have diverged across halls — before the building inspector finds them.
Marchetti's day · design intent under pressure
The architectural day — in the order it actually arrives.
07:45 — RFI digest, Wandsworth
Before the train. Loadbearer has processed overnight: three new RFIs in scope, two substitution requests awaiting architectural opinion, one deviation report raised by Halloran's site team on Hall 2 flooring finish. RFI-2847 — the IMP cladding substitution — is at day four of its five-day SLA. Marchetti flags it for the 09:15 call and opens the drawing it references. She has the current revision, the specified product, and the proposed alternative on one screen before she locks the front door.
09:15 — Phoenix Digital design review
The weekly design review with Krupa's team and Marauder's design manager. RFI-2847 is on the agenda — Marchetti has the deviation impact statement drafted. The specified panel is not merely aesthetic: the through-colour finish is part of the planning approval facade schedule. A substitution requires a design change notice, a client-approval decision above the £50k threshold, and notification to the planning authority. The contractor's covering note said "visually equivalent." It was not.
11:00 — Site walk, Hall 2 level 1
Three deviation reports to verify. Pod B: door ironmongery installed — the lever handles are a stock alternative, not the specified security-rated set. The substitution was not raised as an RFI; it was made as a site decision by Vasquez Drylining. Pod C: fire-stopping at slab edge uses a different batt configuration than the FlameSeal CDP design. Pod D: the containment tray routing in the exposed ceiling zone departs from the aesthetic alignment drawing. All three are now in Loadbearer — photographed, location-tagged, deviation ID raised, Marchetti as named owner.
13:30 — RFI clearing block
Four RFIs requiring architectural response before the end of day. Two are substitution requests — one for the door hardware set across the security zone (42 doors), one for a grille type in the louvre integration package. One is a fire engineering crossover: the compartmentation detail at Hall 3 / Floor 2 slab edge differs from the approved fire strategy, and FlameSeal's CDP designer has raised a TQ asking whether the IFC drawing or the strategy governs. That one goes back to the fire engineer before Marchetti can opine. One is a straightforward finish clarification — she responds in four minutes.
15:00 — Design intent review with Halloran and Shankar
Fortnightly. The three of them work through the deviation register: which items are closed, which are pending Marchetti's opinion, and which have been built without resolution. Hall 1 is largely clean. Hall 2 has eleven open deviations — three from today's walk added. Hall 3 is early stage but two substitution requests are already in the queue. Shankar flags that the rooftop louvre orientation on Hall 3 may need revisiting — the cooling strategy has shifted since the IFC drawing was issued and the plant-side clearance is no longer what the drawing assumed.
17:30 — Drawing issue review and approval
Two revised drawings from the design firm awaiting Marchetti's IFC sign-off: the revised slab-edge fire detail that responds to the FlameSeal TQ, and the updated louvre integration drawing for Hall 2. She checks them against the open deviation register — do they resolve the items currently in the queue, or do they create new ones? The louvre drawing closes two open deviations and introduces a third: a dimensional change that affects Apex Mechanical's plantroom door clearance. That gets routed to Halloran before sign-off is given.
At your fingertips, every design day
The design picture Marchetti never had to reconstruct.
What stops happening
- The RFI that completes two contractor-side review rounds and nearly becomes a built decision without the architect being copied once.
- The Friday-afternoon deviation spreadsheet attachment — reconstructed, not live, and already out of date by the time it arrives.
- The "visually equivalent" substitution that is not equivalent — but the non-equivalence is buried in an attachment that nobody opened until the panel was already on site.
- The Monday morning spent reconciling two RFI trackers — the contractor's and Marchetti's own — to find the items requiring an architectural opinion this week.
- The fire-stopping detail built differently across halls because the design clarification was verbal and never reached the FlameSeal CDP register.
- The as-built drawing package assembled at handover that shows where the building ended up, with no audit trail of when each departure happened or who approved it.
- The design change above the client-approval threshold that moved through the contractor's CCB without Krupa being notified — because the design event and the commercial event lived in different systems.
- The handover meeting at which Marchetti learns, for the first time, that the louvre orientation on Hall 3 was changed six months ago and the as-built drawing does not reflect it.
Failure modes · forensic, not decorative
The substitution that built itself — and three others like it.
-
AR-008
A specified IMP façade panel — dark bronze through-colour, 18-week lead — was substituted for a "visually equivalent" stock alternative across all 54 pods after cycling through three RFI rounds without the architect being copied. The contractor's design manager approved at round two; by round three the panels were already on order. Marchetti was copied on round three as a notification, not a consultation. The substituted product did not meet the planning-approved facade schedule. A retrospective planning variation took eleven weeks and delayed practical completion.
Loadbearer routes every RFI with a specification reference to the named design authority at the moment it is raised — not after contractor-side rounds have narrowed the options. An RFI referencing the facade package is on Marchetti's queue before the first contractor review. "Visually equivalent" is a description, not a decision. The decision belongs to the architect.
-
AR-014
The fire-stopping detail at slab edge — EI90 compartmentation, FlameSeal batt-and-collar system per the approved CDP — was installed with a batt-only configuration on Hall 1 and a collar-and-compound configuration on Hall 2, because two different FlameSeal operatives had interpreted a TQ response differently. The discrepancy was not in either operative's deviation register. It was found by the building control inspector at practical completion, requiring remedial works to 23 penetrations on Hall 1 and a 19-day programme impact.
The penetrations and firestopping register in Loadbearer holds one CDP design per penetration type — not two verbal interpretations. Every sealed penetration carries a FlameSeal certificate, a photograph, and Marchetti's sign-off. A per-zone RAG surfaces divergence from the approved detail the moment an installation record is submitted. The building control inspector finds a certificate, not a discrepancy.
-
AR-022
The specified door ironmongery across the Cranebank security zone — 180 doors, 12 hardware sets, security-rated lever handles with restricted key profile — was quietly substituted for a stock commercial-grade alternative by Vasquez Drylining during the Hall 1 fit-out programme. No RFI was raised. The substitution was recorded as a site instruction on the contractor's internal system and never routed to the architect. Marchetti discovered it at the Hall 1 mock-up inspection, by which point 47 doors had been fitted. The security integrator confirmed the stock hardware did not meet the access-control interface specification.
Loadbearer's deviation register captures any installation that departs from the specification — whether it arrives as an RFI, a site instruction, or a contractor internal note. An item installed against a drawing revision that has not received architectural sign-off is a deviation. It enters the register, it gets a named owner, and it gets an opinion. The 48th door is not fitted before the first 47 are reviewed.
-
AR-031
The rooftop exhaust louvres on Hall 3 — 142 items, orientation and free-area calculated against the free-cooling strategy in the NABERS BF-1 evidence pack — were installed with a 90-degree rotational deviation from the IFC drawing. The deviation originated in a plant-room coordination change made at RIBA Stage 5 that moved the primary exhaust duct centreline. The MEP coordinator updated the structural holding-down arrangement; nobody updated the louvre orientation drawing. The IFC drawing issued to site was correct as-drawn but wrong as-coordinated. The NABERS assessor flagged the deviation; the free-area calculation had to be reworked. The as-built louvre performance is within tolerance — but only just, and the evidence pack took four weeks to reconstruct.
Loadbearer connects the louvre integration page — a DCH lens page owned by Marchetti — to the MEP coordination register. A change to the duct centreline triggers a deviation flag on the louvre drawing before the holding-down arrangement is updated, not after the panels are installed. The NABERS evidence pack is a live query against the record, not a four-week reconstruction. The assessor receives the correct free-area calculation on the day they ask for it.
"A building loses itself in a thousand silent substitutions. Loadbearer doesn't argue with the substitution. It just makes sure the substitution is visible."

The golden thread · what Loadbearer enables for the architect
The record that runs from issue-for-construction to as-built — without a gap in the middle.
The architectural golden thread is a legal obligation under the Building Safety Act and a practical necessity on a £340M data hall. It is the continuous, auditable connection between what was specified, what was approved to change, and what was built. On Cranebank, with 54 pods, 320 drawings, and an RFI log that will run to several hundred items before handover, the golden thread is not a document — it is a live record. Loadbearer is that record.
The deviation register is not a retrospective list of what went wrong. It is a live feed of every departure from design intent — whether it was raised as an RFI, surfaced at a site inspection, identified in a TQ, or caught in a drawing comparison. Each deviation carries a drawing reference, a specification clause, a named owner, and a status: pending opinion, approved, rejected, or built-without-resolution. The last category is the one that matters. Loadbearer makes it visible.
The substitution audit trail answers the question that handover always raises: when was this decision made, who made it, and what was the design authority's position? On Cranebank today, that question is answered by searching three email archives, one contractor RFI tracker, and Marchetti's own notes. On Loadbearer, it is answered in a single indexed query — product specified, product substituted, RFI reference, architectural opinion issued, client approval status, date of each. One record. No reconstruction.
Design-intent-as-data means that the design intent for each element of Cranebank is not locked inside a drawing that nobody can query — it is a structured record tied to a location, a package, and a set of approved parameters. When Marchetti gives an architectural opinion, it is recorded against that record. When the contractor installs something different, the departure is flagged against it. The gap between intent and reality is not discovered at handover. It is surfaced when it opens.
Loadbearer does not make architectural decisions. It surfaces the information that Marchetti needs to make them — and it records the decisions she makes so that Krupa, Halloran, and Donnelly can see the line between what was designed and what was built. The system signs nothing. Marchetti signs everything.
"My job is not to stop the substitution. My job is to know about it — in time to have a view. Loadbearer gives me that. It gives me the gap, before the gap is built."

Adjacent
The same record — from the client above and the contractor below.
Marchetti's deviation register is the same record that Halloran's programme view reads for design-driven programme risk, that Coughlan reads for commercial events above the approval threshold, and that Krupa reads for client-approval decisions. One source. The design intent Marchetti custodies runs from the drawing issue log to the as-built record without a gap — because the gap is what Loadbearer was built to close.
"The system that signs nothing for you."
