Procurement
How an enquiry is handled
The process behind a quotation, set out in full, including the points where we will tell you a requirement cannot be served well.
Daverlan is an independent sourcing company. We do not manufacture, we do not hold stock and we carry no manufacturer authorisation. What we provide is a disciplined route from a specification to quotations that can be compared, and a direct answer when a requirement cannot be met.
The sequence
Reference and acknowledgement
Every request receives a reference number on submission, and the details it contained are confirmed by email to the address given.
Specification review
The requirement is checked against a fixed set of fields. Gaps and contradictions are raised before anything goes to a supplier.
Standard and destination
The standard, the loss rules and any restriction at the destination, such as the EU rules on insulating gas, are confirmed.
Sourcing
Equipment routes are identified against the specification rather than against any single supplier's range.
Comparable quotations
Offers are set out on the same basis: scope, standard, documents, condition, delivery basis and validity.
Order and documents
The order is placed against the agreed specification, and the documents listed in the quotation travel with the equipment.
How manufacturers are chosen for a request
| What is checked | Why it matters |
|---|---|
| Published scope covers the rating, the voltages and the standard | A factory is not approached for equipment outside its range |
| Type test reports for the configuration offered | A type test covers the combination that was tested, not a whole product family |
| Routine test documents and a factory acceptance test option | What arrives with the unit is agreed before the order, not after delivery |
| References at a comparable rating and destination | Requested from the manufacturer, and named in a quotation only where the manufacturer permits it |
| Documents in the language the project requires | Many projects require the manual and test reports in the site language |
| Delivery basis, warranty and spare parts terms | Stated line by line in the quotation rather than implied |
No manufacturer is described on this site as approved, authorised or a partner. The checks made for your request are listed in the quotation you receive.
Who is responsible for what
| Task | Daverlan | You and your engineer |
|---|---|---|
| Completeness of the requirement | Checks it against a fixed set of fields and raises gaps | Provides the specification and confirms the design |
| Manufacturer route | Proposes routes and states what was checked for each | Accepts or rejects any route, including by make |
| The offer | One document stating scope, standard, documents, delivery basis, validity, payment terms and warranty | Checks the offer against the design |
| Contract and warranty | Each quotation names the contracting party and who gives the warranty | Approves the terms before order |
| Factory tests and documents | Coordinates test dates and the delivery of the documents listed in the order | Witnesses tests where required and approves documents |
| Delivery | Quotes transport as a separate line when delivery to site is requested, with the Incoterm stated | Prepares access, foundation and lifting on site |
Destinations
Every request is checked against EU sanctions for the destination, the end user and the equipment before it is quoted, and a request can be declined for that reason alone. The destination also decides which standard and which loss rules the equipment has to meet, which is why it is a required field.
Start from your situation
| Situation | What to send |
|---|---|
| A specification or tender document | The document itself. We work to it line by line |
| A bill of materials | The list, with any drawings it refers to |
| A single line diagram and a rating | The diagram, the voltages and the site |
| A failed unit that needs replacing | Nameplate photographs, the voltages, and how urgently it is needed |
| Drawings, schedules or several documents | Up to five files with the request, 15 MB in total, including PDF, DWG, DXF, spreadsheets and photographs |
| A new connection being planned | The load, the connection voltage and the network operator |
Condition of equipment
| Condition | How it is handled |
|---|---|
| New | Sourced to the specification, with the manufacturer's documents |
| Surplus | Unused equipment. Considered only when you accept it, with its documents and storage history checked |
| Refurbished | Previously used equipment. Considered only when you accept it, with the work done and the test results stated |
You state which conditions are acceptable in the enquiry. Availability of any condition is confirmed per enquiry and never assumed.
What we do not do
| Activity | Who does it |
|---|---|
| Installation and commissioning | A qualified electrical contractor |
| Design sign off and protection settings | The responsible engineer and, where required, the network operator |
| Network connection applications | The applicant or their consultant |
| Certification of equipment | The manufacturer and the bodies that test and certify |
What we do not publish
We do not publish prices, stock levels or general lead times. Each depends on the specification, the manufacturer and the timing, and a published figure that cannot be held is worse than none. Every quotation states its own price basis, delivery basis and validity.
