Short period Seismometers and Data Loggers

Description

See Main Tender Document in uploads section. DIAS seeks to purchase 1. a number of analogue 3-component seismic sensors suitable for local seismic monitoring and 2. an equal number of data loggers that are compatible with all current types of analogue seismic sensors. A detailed specification of requirements is set out in Section 2 of the main tender document. Tenders must comply with the format of tender as set out in Section 3 of that document. As can be seen from Section 2 of the tender document we are looking for sets of two types of instruments, a) low power short period seismometers that are compact, light weight, waterproof to at least the IP65 standard and suitable for rapid field deployments, b) data loggers that are suitable for use with broad-band seismometers, short-period seismometers, geophones, infrasound sensors and other DC sensors. They should provide accurate gps based time-stamping of recorded data and be suitable for field installations (i.e. compact, light-weight, with low power consumption and waterproof to at least the IP65 standard). We are asking suppliers to provide quotes for any part or all of the supply and delivery of these instruments and all relevant consumables. To facilitate this, the tender has been broken into two lots as follows: Lot 1: A number of low power short period seismometers and all relevant consumables, excluding batteries and solar panels. Lot 2: A number of low power data logging systems with digitizing and recording capability and all relevant consumables, excluding batteries and solar panels. Note: DIAS will not know until all bids are in and evaluated exactly how many units can be acquired from available funds. Therefore DIAS asks for a price for 25 units, 35 units and an interpolation formula that can be applied for any number of units between 25 and 35 units. Tenderers are entitled to submit tenders for each and every lot.
