The Klang Valley Mass Rapid Transit (KVMRT) System is set to be one of the mega projects in Malaysia. Many of the researches have focused on the causes of construction accident occurrences at the site. Whilst, this study focuses on the consequences (i.e., costs) of the occurrences of the accidents for the project. The work injuries create economic issues for our society. The awareness of accident costs is absent because the stakeholders always leave the matters to the insurance company. They are ignorant of the cost of an accident without realising the greatness of its impacts on the industry and the country. Therefore, this study aims to determine the relationship between accident costs and the factors influencing the accident costs of urban rail infrastructure projects to the Employer. All these factors are known as safety and health cost dimensions. For this research, the Employer, also known as a Contractor, is the person who bears the accident costs (direct and indirect costs) of the project. Multiple regression performed on the sixty-two (62) accident cases from the MRT 1 SBK (Sungai Buloh-Kajang) Line Projects. These findings could heighten the importance of the effect of an accident on the Employer’s company’s economics and budgeting.

The mature larvae of 14 Otiorhynchus taxa are described: O. (Otiorhynchus) armadillo (Rossi, 1792), O. (Nehrodistus) armatus Boheman, 1846, O. (Otiorhynchus) aurifer Boheman, 1843, O. (Pocodalemes) crataegi Germar, 1824, Otiorhynchus (Arammichnus) indefinitus Reitter, 1912 (syn. O. dieckmanni Magnano, 1979), O. (Choilisanus) raucus (Fa-bricius, 1777) and 3 taxa of the O. (Otiorhynchus) tenebricosus complex (Herbst, 1784), O. (Otiorhynchus) clavipes (Bonsdorff, 1785), O. (Otiorhynchus) fuscipes (Olivier, 1807) and O. (Otiorhynchus) lugdunensis Boheman, 1843, are described and illustrated for the first time. The larvae of (Otiorhynchus) meridionalis Gyllenhal, 1834, O. (Pendragon) ovatus (Linnaeus, 1758), O. (Zustalestus) rugosostriatus (Goeze, 1777), O. (Metopiorrhynchus) singularis (Linnaeus, 1767), and O. (Dorymerus) sulcatus (Fabricius, 1775) are redescribed and illustrated, and new characters are added. Important characters of the mature larvae (e.g. chaetotaxy, shape of head and body) are explained in detail and illustrated. A key to the identification of the mature larvae of 19 Otiorhynchus taxa is provided. Breeding and collecting data of the larvae are given, and the study is completed by a current overview on the life histories of all treated species.
