Ambiductor now has a framework agreement with HBV (Husbyggnadsvararor) regarding apartment metering products. Ambiductor received rankings 1-3 in all of the categories offered and we are pleased that our efforts have given us a great deal of this procurement.
HBV is the Swedish Public Service Purchasing Association and consists of more than 330 real estate owners with rental apartments and a turnover exceeding SEK 2 billion.
Ambiductor has worked with apartment metering since its start just over 7 years ago and established itself as a serious and long-term supplier. For a few years we have a framework agreement with Sinfra regarding district heating and utilities. Now we also get a framework agreement with HBV regarding apartment metering, covering everything from the production, distribution and distribution of both water and heat.
Some parts of this tender, Ambiductor has chosen not to quote.
- The central visualization system where we intentionally chose to hand over to partners.
- Vane wheel meters with M-bus and wM-bus, where we have a much more affordable option than winning bids, but our high IP class did not match the procurement.
- We also refrained from submitting a quote on the ring piston meters because we do not think that they meets the quality level we require. Ring piston meters are suitable for oil but unsuitable for cold water.
More about the agreement will be available at http://hbv.se/avtal/alla-ramavtal/imd2/ shortly. The agreement extends over 2 + 1 + 1 years. Below we will try to explain which parts we are involved in.
