  Center for the Gravitational-Wave Universe at Seoul National University has
been operating its main observational facility, the 7-Dimensional Telescope
(7DT) since October 2023. Located at El Sauce Observatory in Chilean Rio
Hurtado Valley, 7DT consists of 20 50-cm telescopes equipped with 40
medium-band filters of 25 nm full width at half maximum along with a CMOS
camera of 61 megapixels. 7DT produces about 1 TB per night of spectral mapping
image data including calibration, and the byproduct of the data reduction
pipeline once our planned three layered surveys (Reference Imaging Survey, Wide
Field Survey, and Intensive Monitoring Survey) start in 2024. We are expecting
to generate 1 PB per year by combining raw data, reduced data, and data
products (e.g. calibrated stacked images, spectral cubes, and object catalogs).
To incorporate this huge amount of data, we now have a data storage for 1 PB
which we will increment by 1 PB per year. We also have a high-performance
computation facility that is equipped with 2 NVIDIA A100 GPU cards since we
plan to carry out real-time data reduction and analysis for follow-up
observation data of gravitational wave events. To incorporate this, we
established a 400 Mbps network connection between the facilities in Korea and
Chile. Taking advantage of the high-performance network, we have been carrying
out fully remote operations since October 2023. In this talk, we present
details of designing, planning, and executing the ground-based telescope
facility project, especially within low-budget academic environments. While we
cover as much ground as possible, we will emphasize human resource management,
project risk management, and financial contingency management.
