A complete calculation of {sigma}(O) ({alpha}) electroweak radiative corrections to the Drell-Yan process for future experiments at the Large Hadron Collider (LHC) is performed. All contributions to cross sections and kinematical constraints are presented; in calculations and in order to simplify programming, the formalism of theta and delta functions is extensively used in numerical estimations. The independence of the results from unphysical parameters is tested, the independence from the parameter separating the regions of soft and hard photons being proven analytically. A numerical analysis of hypothesized effects is performed by means of the READY code in the FORTRAN language with allowance for experimental constraints at the Compact Muon Solenoid (CMS) detector. The electroweak corrections in question prove to be significant in the region of large dilepton invariant masses M, reducing substantially the differential cross section with respect to M and forward-backward asymmetry.
