Site preparation for the installation of an Automated Radiosonde Launching System (ARLS) and an Automated Weather Station (AWS) at the Kuujjuak Upper Air Station in Kuujjuaq Quebec

1.0 Objective:
To engage the services of a contractor with the expertise and resources (i.e., personnel, labour, supervision, equipment, tools, materials, and supplies) to perform foundation, conduit, electrical, and fencing installation work required to prepare for the installation of an Automated Radiosonde Launching System (ARLS) and an Automated Weather Station (AWS) at the Kuujjuak Upper Air Station in Kuujjuaq Quebec.
2.0 BACKGROUND:
Environment and Climate Change Canada’s (ECCC) Meteorological Services of Canada (MSC) is preparing to install an ARLS and an AWS used to release atmospheric monitoring balloons at the Kuujjuak Upper Air Station in Kuujjuak Quebec. These automated systems assist the department in obtaining more accurate and timely data. To complete this work, ECCC requires a gravel pad, a foundation, conduit installation, electrical work, and a perimeter fence.
3.0 SCOPE
Foundation:
MSC requires services to supply a gravel pad and foundations for an ARLS (20’x 8’ ISO shipping container). The shipping container will be pre-equipped with the necessary connection points and twist lock connectors.
Electrical and conduit:
MSC requires electrical services to supply a power feed from the Operations building to an ARLS. The ARLS will be pre-equipped with the necessary connection points and will require a termination for power with a provided plug (Hubble HBL430C12W). If suitable, the existing conduit from the Operations building may be used; this will require the removal of the existing abandoned cable and the installation of a conduit extension (6.5 m) from the end of the existing conduit run to the ARLS. If the existing conduit is damaged or otherwise unsuitable, it should be replaced as a single run from the Operations building to the ARLS (<30m). Electrical grounding for the ARLS and AWS is required per the manufacture’s specifications.
MSC also requires electrical services to supply a communications cable from the Operations building to the ARLS. If suitable, the existing conduit from the Operations building may be used with the removal of the abandoned cable; this would require the installation of a junction box and conduit (6.5 m) from the end of the existing conduit run to extend to the ARLS. If the existing conduit is damaged or otherwise unsuitable, it should be replaced as a single run from the Operations building to the ARLS (<30m).
Fencing:
MSC requires fencing services to supply a gated, 6’ chain link fence around the perimeter of the Kuujjuak Upper Air Station, Kuujjuak QC (~55m x 60m).
