We also present a summary of the current planning behind the 5-year initial phase of survey operations, and some detailed end-to-end science simulations that have been effected to evaluate the final on-sky performance after data processing. WEAVE will provide optical ground-based follow up of ground-based (LOFAR) and space-based (Gaia) surveys. WEAVE is a multi-object and multi-IFU facility utilizing a new 2-degree prime focus field of view at the WHT, with a buffered pick-and-place positioner system hosting 1000 multi-object (MOS) fibres, 20 integral field units, or a single large IFU for each observation. The fibres are fed to a single (dual-beam) spectrograph, with total of 16k spectral pixels, located within the WHT GHRIL enclosure on the telescope Nasmyth platform, supporting observations at R 5000 over the full 370-1000nm wavelength range in a single exposure, or a high resolution mode with limited coverage in each arm at R 20000. The project has experienced some delays in procurement and now has first light expected for the middle of 2019.ELETTRONICOenConference paper10.1117/12.23120312-s2.0-85051241636000452664300028https://www.spiedigitallibrary.org/conference-proceedings-of-spie/10702/2312031/Construction-progress-of-WEAVE--the-next-generation-wide-field/10.1117/12.2312031.short?SSO=12018SPIE10702E..1BDFIS/05 - ASTRONOMIA E ASTROFISICA
