Which isolator family, which capacity class, which testing scope? Every line that enters the specification turns into money at tender. We sit on the owner's side of the table. We compare the options and make the bids readable against each other.
System selection happens at the start of the project, the bill of quantities just before tender. Take both, or only the one you need.
SERVICE 1
Lead rubber bearings (LRB), friction pendulum (FPS) and high damping rubber (HDR) behave differently under the same building. The choice is driven by the displacement demand the site imposes and the vertical loads, not by a catalogue. We prepare the data behind that decision before the designer and the manufacturer are at the table.
SERVICE 2
The bill of quantities is the document the isolation work is priced on. A missing item is invisible at tender and becomes an invoice on site. We do not run the engineer's calculations; we stand beside the owner while the results of those calculations are turned into the list that goes out to bid.
Four steps. The first two take weeks, the last two follow your tender calendar.
Geotechnical report, architecture, storey count, occupancy category, schedule. We start with what exists and list what is missing.
Matrix for the three families, manufacturer shortlist and decision memo. Designer selection is settled at this stage too.
Capacity and displacement values from the engineer's analysis become line items. Testing and inspection items are added.
Several manufacturers bid the same specification. We lay the offers side by side and write down where the difference comes from.
Projects where isolation has been decided, or is seriously on the table. Hospitals and health campuses, data centers, public buildings, tall residential and office, manufacturing facilities. On retrofit projects we come in once the feasibility study is complete.
We advise on projects governed by ASCE 7 Chapter 17 in the United States, EN 1998 (Eurocode 8) in Europe, and TBDY 2018 in Türkiye, where the same service is offered in Turkish.
The manufacturer recommends its own product, the designer its own habit, the contractor its own capability. Each may be right. None of them compares the options on your behalf. An independent advisor does.
We do not design and we do not run the analysis. Engineering decisions and stamps stay with the licensed engineer of record. Our role is comparison and getting the right people in the room.
The fee is written down with the scope. The call fee is credited against the consulting fee.
PROPOSAL
System selection, BOQ preparation, or both. Scope and fee in writing within one business day.
No. Capacities and design displacements come from the engineer of record. We turn those values into the line items that go out to tender and add the testing and inspection items that are usually missing. We also make the bids comparable.
There is no ranking that holds from one project to the next; the price is set at tender. The right method is to bid the same specification to both families. For budgeting, the useful scale is a percentage: isolation typically adds 10 to 15 percent to the structural frame cost.
For system selection, before the design contract is signed and no later than schematic design. For the BOQ, before construction documents are complete. We can still compare bids on projects that have already gone to tender, but there is less room to fix the line items.
A fixed fee against a written scope. Fill in the form and we send the scope and fee within one business day. If you would rather talk first, the 30 minute call fee is credited against the consulting fee.
