Analysis, design, FEA, calculations and detailing — prepared to your engineer’s requirements and issued for their review. You keep the seal. The work behind it is done by me and by assistants working under my direction.

WHO I WORK FOR

Five kinds of client, four kinds of job. Find yourself in one of these and skip the rest of the page.

01 · STEEL FABRICATORS

Delegated connection design and the calculations behind your shop drawings — sized, checked and documented so your engineer signs them off without a second pass.

02 · PRODUCT MANUFACTURERS

One calculation package covering a whole size range instead of one job. Engineer it once, sell it a thousand times, update it when the wind map changes.

03 · PLANT OWNERS AND OPERATORS

Work on your own site, under your own internal engineering authority. Equipment, foundations and the structures that carry them.

04 · CONTRACTORS

Engineering that starts after the permit is issued: delegated design and deferred submittals, the calculations behind substitution requests, answers to RFIs when something does not fit on site, and remote site supervision while the job is being built.

05 · STARTUPS AND INVENTORS

A structural idea with no engineering department behind it yet: modular units, kits, racks, mounts, lifting frames. Feasibility, first sizing and prototype calculations, written so that the engineer who reviews or seals the design has something defensible to work from.

HOW RESPONSIBILITY WORKS

I do not seal drawings. That is deliberate. The seal belongs to a licensed engineer in your jurisdiction. My work is prepared for their review, and the separation is stated up front rather than discovered later.

You have an engineer. I work as your design subconsultant. You set the brief and the standard, I produce the calculations and drawings, and your Engineer of Record reviews and seals them.

You have a plant engineering department. The same arrangement, in house. Your internal engineering authority reviews the work and carries it, exactly as it would for any other supplier.

You have neither. You appoint a licensed engineer in your jurisdiction. They review, comment and seal; I revise to their comments until the package is accepted. Every US permit package I have worked on was handled this way.

On the record. US permit submittals, including LADBS and Orange County, California, have been reviewed, commented on and sealed by client-appointed licensed engineers. Review cycles are part of the job, not an exception.

ELEVEN CODE FAMILIES, TWO ENGINEERING TRADITIONS

Most engineers work to one code for their whole career. Working across both the Western and the post-Soviet families is unusual, and it is what makes a project in Kazakhstan and a project in Queensland the same kind of problem rather than two different careers. It is also why practices with their own engineering department bring me the job that falls outside the code they work to every day: they have the engineer who reviews and seals it — what they do not have is the code.

TEN YEARS OF GAS FACILITIES, BY THE OBJECT

Underground gas storage and the development of new gas-oil condensate fields, 2004–2014, as a staff engineer in design institutes. Objects, not clients — the list is the point.

Gas compressor buildings · Air compressor buildings · Platforms for gas pumping units · Booster compressor units · Gas metering sites · Gas metering buildings · Gas distribution buildings

Gas separation buildings · Separator platforms · Gas flushing and drying buildings · Gas cleaning buildings · Gas treatment plant sites · Gas cooling plant sites · Air cooler installations

Regeneration facility · Nitrogen plant sites · Steel tanks with foundations · Underground drainage tanks · Platforms for waste tanks · Waste storage sites · Oil warehouses

On-site overpasses and pipe racks · Lightning masts and poles to 40 m · Transformer substation buildings · Diesel power facilities · Pumping and sewage stations · Repair and storage units · Modular buildings and checkpoints

A DEFINED PACKAGE, NOT OPEN-ENDED HOURS

CALCULATIONS

Load schedule · analysis model · member and connection checks · foundation design · TEDDS report issued for review

DRAWINGS

General arrangement · framing plans · sections and details · connection details · schedules and takeoff

MODEL

Revit, Tekla or SAP2000 · handed over on request · native files, yours on final payment · quantities extracted

REMOTE SITE SUPERVISION

Photo and video walkthrough review · built-versus-drawn checks · RFI responses · written notes your engineer can act on. Statutory inspections stay with your local licensed inspector.

STEP 1 · BRIEF

Sketches, loads, codes and the standard your engineer expects. A photo of an existing drawing is enough to start.

STEP 2 · DESIGN

Analysis, sizing, connections, foundations. Every assumption written down where a reviewer can find it.

STEP 3 · REVIEW

Your engineer comments. I revise to those comments until the package is accepted. Included, not extra.

STEP 4 · ISSUE

Final calculations, drawings and model, ready for seal.

184 PROJECTS. 29 COUNTRIES. SINCE 2004.

Every structure was analysed, designed or detailed by me — as a staff engineer and as an independent consultant. Largest blocks: 82 United States · 21 United Kingdom · 16 Faroe Islands, one client over six years · 13 Australia · 7 Russia, industrial and healthcare.

THE SAME WEEK: A 1300-BED HOSPITAL AND A BEAM FOR A KITCHEN

A short pull from the record, chosen for spread rather than size. Each one posed a different problem.

GUYANA

Conveyor structure, 34 m, 365 tph. Long span, moving load, and a site with no fabrication capacity within reach.

GERMANY

FRP cooling tower — stress and vibration. Pultruded polymer, not steel: different stiffness, different failure mode, different code.

FAROE ISLANDS

Pier strength against waves. Wind was not the governing load. The sea was.

SAINT VINCENT

Island resort with no crane on the island, no steel supplier and one ferry a week. Designed to arrive in a container and go up by hand.

RUSSIA

1300-bed hospital and a regional perinatal centre. Large complex buildings as a staff engineer, with full structural responsibility.

UNITED STATES

Tieback anchor and vinyl sheet pile wall. The contractor carries the risk here, and the numbers must be right first time.

QUESTIONS I GET ASKED

Can you seal drawings?

No, and I do not offer to. The seal belongs to a licensed engineer in your jurisdiction; my work is prepared for their review. That separation is deliberate.

Who owns the calculations and models?

You do, on final payment. Native files are handed over on request: SAP2000, Revit, Tekla, DWG.

How many revisions are included?

Every revision that comes from a reviewer’s comment on my own work. Changes to the brief are quoted separately, before I start them.
