NEXUS Studio | DDEG: RFP Responses From 3 Weeks to 1 Day

DDEG knew what it needed: a tool that drafts tenders from the building code and its winning bids. It had no software team, and an AI pilot it couldn't trust near a certifier. A NEXUS Studio squad took the tool to production; tenders now take a day, not three weeks.

The question they were asking: How do we get this built and live, safely, without hiring a software team?

NEXUS Studio | DDEG: RFP Responses From 3 Weeks to 1 Day

Meet DDEG

DDEG is a performance-based engineering consultancy: fire safety, accessibility, acoustics and building code advice from eight offices across Australia. Its work sits between architects and builders, the certifiers who approve their designs, and the government and institutional owners who commission them. Every tender answer cites the National Construction Code, so a stale clause is a compliance claim a certifier can reject. And for all its engineers, DDEG had no one who writes software.

They knew what to build. They had no one to build it.

Every tender took around three weeks of a senior engineer's time, mostly spent hunting for answers DDEG had already written. The team knew the fix: one tool that drafts from the current code and its best past bids.

An internal ChatGPT pilot proved the idea in a week, then cited superseded code in its first real draft, with no audit trail and no one accountable for the output. Hiring a software team would take six months before a line of production code, and DDEG would have to run it.

What waiting for a build cost DDEG

Expert time

Est. 60 hrs / tender

Senior engineers searching past bids and drafting, instead of billable client work.

Tenders passed on

Est. 1 in 3

Tenders DDEG qualified for but let go, because no engineer could clear three weeks.

Time to hire

Est. 6+ months

To recruit, onboard and run a software team before a line of production code.

60 hours × $160 × 40 tenders a year ≈ $384k a year

About $32k for every month the tool wasn't live, before counting the tenders never answered.

How Studio built it, then put it to work

NEXUS stages applied, each run by a Studio component. Delivered using the method now productised as NEXUS Studio.

Stage 01

Discover

Traced one live tender end to end, then fixed the product, squad, monthly fee and what "live" means before any build.

NEXUS: Fixed Envelope

Stage 02

Design

Six questions answered. The big call: retrieval over generation, so every answer traces to the NCC and Australian Standard Clauses.

NEXUS: Built to Last Blueprint

Stage 03

Deliver

A dedicated squad ran inside DDEG's team. AI agents coded each ticket, engineers reviewed every change, and working software landed.

NEXUS: ADLC · Bi-weekly Live Build

Stage 04

Operate

DDEG's team runs it on every tender, with the playbooks to own it. The first month of Sustain watched it in live use.

NEXUS: Production Crossing · Independence Kit

The governed path caught it before a consultant did

In the fifth fortnightly build, drafts for an aged-care tender cited fire-separation clauses from NCC 2019, lifted from an older project. The code-edition test in the ADLC's QA step failed the build before it reached production, and the Delivery Trail showed DDEG exactly why. Engineers added an edition filter: any clause the engine can't match to the current code now goes to a DDEG engineer, not into the draft.

"A fast answer that cites last edition's code is worse than a slow one."

— Delivery Lead, EB Pearls

AI agents built it. Engineers decided.

Specialist AI agents planned, coded and tested every ticket, each with one job and narrow permissions. Three calls they never made: what the engine learns from, what it's allowed to write, and what reaches production.

What went in

Only answers an engineer would sign today

DDEG's principal engineers and our team chose the sources. Past projects and answers citing superseded code editions were left out: nothing true to learn from.

What was killed

The engine never prices a bid

Auto-drafted fee proposals were on the table. DDEG wanted pricing kept with people, so we killed it: the engine drafts the technical response, an engineer sets the fee.

Who signed off

One path to production, two approvals

First, a senior EB Pearls engineer merged every change on the path from ticket to production. Second, DDEG's principal engineer accepted drafts against 10 submitted tenders, and go-live was DDEG's call.

“Is AI-written code safe for compliance work?”

Yes, because no agent can ship it.

Agents write and test code but can't merge it. Every pull request is reviewed and merged by a senior EB Pearls engineer. Nothing reaches production without human approval. DDEG sees every review and release in the Delivery Trail.

The results, against DDEG's baseline

DDEG's result, on DDEG's tenders. Yours starts from your own baseline.

Business translation	52 engineer hours saved per tender	$333k a year52 hrs × $160 × 40 tenders, at the old volume

Same tender. Different fortnight.

Before

A fire engineer clears three weeks between client jobs, digs through old projects on the shared drive, and re-checks every clause against the current code by hand.

After

By the end of the day the engine has drafted it from the code, project data and DDEG's best past answers. The engineer checks the flagged clauses, adds judgement, and is back on client work tomorrow.

And DDEG kept building. It kept the same squad for a second release, expressions of interest and capability statements, then moved the product to NEXUS Sustain, where each new NCC edition is loaded the month it's adopted.
