01 /Why Fineline

Breadth is the point

Over a decade across discipline-specific and multi-discipline projects, on multi-national jobs, and leading a team of engineers doing the same. Most problems on a plant don't arrive neatly inside one discipline — and where something genuinely needs a specialist, we'll say so and bring one in.

Senior every time

You deal directly with a Chartered Professional Engineer on every job. The person scoping the work is the person doing it and signing it off.

Fast, because fast is value

A lean, AI-augmented operation moves quicker than a big firm without dropping rigour. Results delivered now are worth more than results delivered eventually.

Right, or not at all

Straight answers, fair pricing, nothing cut that compromises safety or integrity. Everything under Fineline's name is checked against first principles and owned by an engineer.

Services

Most problems on a plant don't arrive inside one discipline.

Six families of work and one chartered engineer across all of them. Start with whatever's actually in front of you — sorting out which discipline it belongs to is our job, not yours.

01 /Start with what you've got

Or start with who you are Plant or facility owner · Project engineer · Mechanical contractor or fabricator · EPC / turn-key contractor · OEM or manufacturer

02 /The six families

Is this us?

Call us if

  • You need a chartered engineer's design, calculation or sign-off on mechanical plant or equipment
  • You've got pressure equipment or lifting gear that needs designing, modifying, assessing or certifying
  • Something has failed, or is showing signs it might
  • You need a project scoped, specified, tendered or managed — and you want it done owner-side
  • Your drawings don't match your plant
  • You're a contractor carrying design liability you'd rather hand to an engineer
Straight answers

Not us if

  • You need primary building structure designed — that comes through a design partner. Equipment supports, non-structural building elements and non-building structures are our own work.
  • You need a building consent for a building
  • You need someone on site full-time for months on end — we keep capacity free for every client. A few weeks of full-time shutdown or construction-phase monitoring is very much in our wheelhouse, though.
  • You want a number without a scope — happy to help you build the scope first
Still not sure?

Not sure which one it is? Neither are most people who call.

Describe the thing in front of you in a line or two. If it's not our work we'll tell you, and point you at who it is.

Pressure vessels & piping

Design, modification and verification of pressure equipment for Bay of Plenty industry — and a plain answer to the question that actually holds jobs up: which hazard level is this, and who's allowed to verify it?

01 /What this covers

01
Vessel design

New pressure vessels designed to the applicable standard and classified under AS 4343, delivered with the calculation set and drawings a fabricator can build from.

02
Piping design

Pressure piping design and modification — including the supports, restraint and routing that decide whether it can actually be installed.

03
Brownfield modification

Changes to existing pressure systems, where the constraint is what's already there and the drawings rarely match it. Usually starts with a scan.

04
Design verification — Hazard Level E

Verified by Chris in his own right as a Chartered Professional Engineer. No third party, no queue, no handoff.

05
DV facilitation — Hazard Levels A–D

These need an IANZ-accredited design verifier. Fineline prepares and packages the design, manages the verifier relationship, and closes out the comments.

Standards worked to
[pressure-equipment standards — e.g. AS/NZS 1200, AS 1210, AS 4343, AS 4041]
What to send to get a quote

The existing drawings if you have them, the design conditions — pressure, temperature, contents — and a photo of the nameplate. If you've got none of that, say so. Half the jobs here start with a site visit and a tape measure.

The question everyone asks

Which hazard level is my equipment, and who can verify it?

Pressure equipment in New Zealand is classified by AS 4343, which sorts it into Hazard Levels A through E. The classification comes from what the equipment holds, at what pressure and volume, and what happens if it lets go — not from what it costs or how big it looks. A is the highest hazard; E is the lowest.

Under the PECPR Regulations, the design of pressure equipment has to be verified by someone competent to do it, independently of the designer. Where that line falls is what most people are actually asking about.

For Hazard Levels A to D, design verification must be carried out by an IANZ-accredited design verifier. Fineline is not one, and won't pretend otherwise — what we do is prepare and package the design so it survives verification, manage the relationship with the verifier, and close out their comments. That's usually where the time goes anyway.

For Hazard Level E, a Chartered Professional Engineer can carry out design verification in their own right. Chris does that himself, which for a lot of plant equipment removes an entire external step from the programme.

If you don't know which level your equipment is, that's the normal starting point rather than a problem. Send the nameplate and the design conditions and we'll tell you.

07 /Other work we do

OPTIONAL IMAGE — full bleedLifting beam, spreader bar or crane in service · on site · 1800×1000 min
currently a designed band, no stock stand-in

Cranes & lifting equipment

Design, analysis and certification of lifting equipment — including the gear already on your site that turned up years ago without a shred of paperwork.

01 /What this covers

01
Retrospective assessment of existing gear

Every site has lifting equipment with no design file, no certificate and no idea who made it. We assess what's there, work out what it can safely be rated to, and give you the documentation that should have come with it.

02
Lifting beams, spreader bars & general lifting equipment

Design and analysis of new lifting equipment, sized to the actual lift rather than to a catalogue.

03
Mancages & forklift work boxes

Design and compliance for equipment that puts people in the air — the category where the paperwork gets looked at hardest, and rightly.

04
Crane design & DV facilitation

Crane design, and management of the design-verification process where accredited verification is required.

05
Certification of non-crane lifting equipment

Certification of lifting equipment that doesn't constitute a crane under the PECPR Regulations — the grey area most enquiries land in.

Standards worked to
[lifting standards — e.g. AS 1418, AS 4991, and the PECPR-relevant set]
What to send to get a quote

Photographs, any markings or plates still legible, the load you need it rated for, and how it gets used. For new design, the lift itself — what, how heavy, from where to where.

07 /Other work we do

OPTIONAL IMAGE — full bleedFabrication shop or plant equipment mid-install · 1800×1000 min
currently a designed band, no stock stand-in

Mechanical engineering & design

The core discipline, and the one most work arrives through. Plant and equipment designed to be built, installed and maintained — not just to pass a calculation.

01 /What this covers

01
Plant & process equipment design

Equipment design for industrial process plant, from a single item through to a connected system.

02
Mechanical structures

Equipment supports, non-structural building elements and non-building structures — plus access, platforms and fall-arrest anchor design. Primary building structure comes through a design partner; this doesn't.

03
Brownfield modification

Modifying plant that's already running, already crowded and already documented wrong. The design constraint is the site, not the standard.

04
Product development

Mechanical product development for manufacturers and OEMs — concept through to a design that can actually be made.

05
Analysis, where it earns its place

Finite element analysis sits underneath the design work rather than beside it. We use it where the hand calculation runs out, not to decorate a report.

Standards worked to
[mechanical / structural design standards you work to]
What to send to get a quote

07 /Other work we do

OPTIONAL IMAGE — full bleedCapital project under construction, or a site meeting · 1800×1000 min
currently a designed band, no stock stand-in

Project & design management

Owner-side engineering on capital work — specified, tendered and managed by the engineer who did the design, rather than by a coordinator who didn't.

01 /What this covers

01
Specification & scope development

Turning “we need to fix this” into a scope a contractor can price and a plant can live with.

02
Tender packages

Documentation packaged so the prices you get back are comparable, and so the thing you receive is the thing you specified.

03
Tender review & evaluation

Review and evaluation of submissions, including the liability triage that decides which qualifications you can accept and which ones you can't.

04
Design management

Managing the design across disciplines — including civil/structural scope, where the design itself is partner-delivered and named as such.

05
Quality management support

ITPs and quality plans, written for the job rather than lifted off a previous one.

What to send to get a quote

The problem, the rough budget if there is one, and the date it has to be working by. Documentation is a bonus, not a prerequisite.

Before you ask

How we take this work

Two rules, and we'd rather say them upfront than disappoint you later. We don't go full-time on a single project — capacity stays available to every client, and a consultant who's been swallowed by one job is no use to anyone else. And we take project engineering where Fineline has design involvement in the work, because an engineer who knows the design is worth considerably more than a coordinator who doesn't.

The deliberate exception: a few weeks of full-time shutdown or construction-phase monitoring, which is exactly the work that needs someone on site.

07 /Other work we do

OPTIONAL IMAGE — full bleedAgeing plant, corrosion or a failed component · close-in · 1800×1000 min
currently a designed band, no stock stand-in

Assessment & investigation

Work that starts with something already built — and often with something that's already gone wrong. Independent, documented, and written to survive being read by someone who disagrees with it.

01 /What this covers

01
Plant & equipment condition assessment

What condition it's actually in, what that means for how long you can keep running it, and what to do first.

02
Structural condition assessment

Assessment of equipment supports, platforms, non-building structures and the steelwork holding your plant up.

03
Forensic & failure analysis

What failed, why, and whether anything else on site is about to do the same. Written knowing it may end up in front of an insurer, a regulator or another engineer.

04
Independent design & peer review

A second senior set of eyes on someone else's design — or on your own, before it goes out.

05
Fitness-for-service & remaining life

A defensible view on whether ageing equipment can stay in service, and on what basis.

What to send to get a quote

Photographs, and what happened. For a failure, don't tidy up first and don't throw the broken part away — both are more common than you'd think, and both make the job harder.

07 /Other work we do

OPTIONAL IMAGE — full bleedScanner on a tripod in plant, or a point cloud on screen · 1800×1000 min
currently a designed band, no stock stand-in

Reality capture & documentation

Measure it once, properly. Everything downstream — the retrofit, the tender, the fabrication drawing — stops being a guess.

01 /What this covers

01
3D laser scanning

Point-cloud capture of plant, buildings and equipment. A day on site replaces a fortnight of arguing about which drawing is right.

02
Project & as-built modelling

Modelling from the scan — as-built, as-fitted, and accurate enough to design against.

03
Retrofit clash checking

Checking new equipment into existing space before it's fabricated, rather than discovering the problem with a crane on hire.

04
Shop drawings & documentation packs

Fabrication and shop drawings, and documentation packs assembled so the next person can find things. Document control available where a project needs it.

What to send to get a quote

The area or equipment you need captured, and what you're going to do with it afterwards — the end use sets the accuracy, and the accuracy sets the price.

Chris Lines

CPEng · MECHANICAL ENGINEER

Chris is a Chartered Professional Engineer with [X] years in mechanical engineering consulting across the Bay of Plenty industrial base — pulp and paper, geothermal, food and dairy processing, and heavy fabrication.

Fineline is the consultancy he always intended to build: one senior engineer, on call, taking mechanical problems end to end — without the layers a big firm puts between you and the person actually doing the work.

01 /How we work

01

Do it right, or don't do it at all

Straight with clients when the answer isn't what they want to hear. In a small market, reputation is the thing that compounds — the right way is also the smart way.

02

Value first, profits follow

We solve the client's actual problem the best way we can. When a call comes down to more margin versus more value to the client, value wins.

03

Be the cape, not the headache

Working with a consultant should be a relief, not a frustration. We're not here to borrow your watch to tell you the time — we turn up, we get it sorted, and you come away glad you called.

04

AI in the workflow; engineer on the sign-off

AI clears the overhead so the work that needs an engineer gets the attention it deserves. Everything under Fineline's name is verified against first principles and owned by an engineer.

The name

A tolerance is a fine line — the gap between fit and interference, pass and failure. So is the threshold between fine and genuinely good.

Engineering is drawing lines, and the discipline lives or dies on how fine they are. Fineline does precise, drawn-to-tolerance work — and runs at threshold: hard, controlled, repeatable, never past the edge.

And, honestly? The surname's Lines. The fine-line reading just earned its place.
