The paper investigates directives addressed to tower crane operators by a construction worker. By examining grammatical variation in connection with load relocation tasks, the study shows how the design and the sequential positioning of directive turns vary systematically according to a particular phase of the work task and the overall structural organization of the activity. The worker's selection of lexico-syntactic forms and embodied actions displays an orientation to the different stages of the work task being carried out. The sequential, compositional and morpho-syntactic differences in the formation of directives serve to manage and display task progressivity. The worker speaks L2 Norwegian with several unidiomatic features, but nonetheless displays a systematic differentiation between the forms in orienting to the sequential and phase-structural characteristics of the actions being performed.

本文调查了建筑工人针对塔吊操作员的指令。通过检查与负载重定位任务有关的语法变化，该研究显示了指令转弯的设计和顺序定位如何根据工作任务的特定阶段和活动的整体结构组织而系统地变化。工人对词汇句法形式和具体动作的选择显示了正在执行的工作任务的不同阶段的方向。指令形成中的顺序，组成和词法上的差异有助于管理和显示任务的进度。这位工人说L2挪威语，具有一些独特的功能，
