Natural Resources Institute Finland (hereafter referred to as "Luke") requests your tender for automated soil gas flux systems with this Call for Tenders and its annexes.
Luke is planning to procure two (2) automated soil gas flux systems in 2024 to Ruukki experimental station (Siikajoki, Finland), one system for measurements of soil gas fluxes in high vegetation and one system for measurements of soil gas fluxes in low vegetation. This procurement consists of two lots with different requirements. All devices will be used in field conditions in Finland over three seasons (spring, summer, fall) for the purposes of forest and agricultural studies. During spring, summer and fall the temperature may drop below freezing point. Therefore, the chambers and equipment must withstand conditions below 0°C. Devices/systems will be used with Luke's existing trace gas analyzers, specifically Licor LI-7810 and LI-7820 and therefore the systems offered must be compatible with them. Devices must also be compatible with other analyzers with or without modifications.
The Call for Tenders and the procurement is divided into two (2) lots:
LOT 1, HIGH VEGETATION includes:
A system including 3 opaque chambers and 3 transparent chambers (The chamber or a combination of offered chambers must be able to measure simultaneously transparent and opaque. If the same chamber can be used for opaque and transparent measurements, the total number of chambers to be included is 3.) for a measurement set-up capable to measure in high vegetation up to 70 cm, 1 multiplexer, 1 datalogger and additional hardware required to form a GHG measuring system with analysers (analysers not included).
Option 1: Lot 1 includes an option for Luke to purchase 5 pairs of opaque and transparent chambers (pair = 1 opaque and 1 transparent chamber) within the next four years.
Option 2: Lot 1 includes an option for Luke to purchase 2 additional multiplexers within the next four years.
Option 3: Lot 1 also includes an option for Luke to purchase an off-grid power supply capable to power system of minimum of 8 chambers with chamber types offered in lot 1 in addition to two trace gas analyzer (max combined power draw 130 W, steady state after warm up 44 W, analyzers accepts 10.5 to 33 VDC) in temperatures ranging from -5 to 40 °C. The tenderer is not required to offer this option.
LOT 2, LOW VEGETATION includes:
A system including 4 portable opaque chambers for a measurement set-up capable to measure with vegetation up to 30 cm, 1 multiplexer, 1 datalogger, 1 cellular communication system datalogger and additional hardware required to form GHG measuring system with analysers (analysers not included). For Lot 2 there also needs to be a capability to monitor and configure the system remotely over cellular network.
Option 1: Lot 2 includes an option for Luke to purchase 10 opaque chambers within the next four years.
Option 2: Lot 2 includes an option for Luke to purchase 2 additional multiplexers within the next four years.
Option 3: Lot 2 includes an option for Luke to purchase 2 dataloggers within the next four years.
Option 4: Lot 2 also includes an option for Luke to purchase an off-grid power supply capable to power systems offered in lot 2 (+ 4 additional chambers) in addition to two trace gas analyzer (max combined power draw 130 W, steady state after warmup 44 W, analyzers accepts 10.5 to 33 VDC) in temperatures ranging from -5 to 40 °C. The tenderer in not required to offer this option.
Tenderer can leave a tender for one or both of the lots. The supply purchase contract in each slot will be made with one supplier.
