29．所有施工必需的活動，凡符合契約許可證的規定，必須開展，從而保證不無故妨礙公眾的便利，或妨礙公共或私人道路的通行、使用和占用，無論道路是通向或是在業主或其他人的地產上。倘若發生此類應由承包人負責的事件，承包人必須保護業主免受由此而引而起的任何索賠、訴訟、損害賠償費、訴訟費、開支和費用的損害。
30．（1）the contractor shall use every reasonable means to prevent any of the highways or bridges communicating with or on the routes to the site from being damaged or injured by any traffic of the contractor or any of his sub一contractors and，in particular，shall select routes, choose and use vehicles and restrict and distribute loads so that any such extraordinary traffic as will inevitably arise from the moving of plant and material from and to the site shall be limited asfar as reasonably possible，and so that no unnecessary damage or injury may be occasioned to such highways and bridges．
30．1承包人必須採取各種合理手段，防止連線或通向工地的任何公路或橋樑由於承包人或其任何轉包人的使用而遭受損害，承包人尤其必須挑選路線、選擇使用車輛，限制和分散裝載量，從而使因往來於工地的設備和材料的運輸而必然造成的異常交通儘可能地被合理限
制，由此避免對公路和橋樑造成不必要的損害。
（2）should it be found necessary for the contractor to move one or more loads of constructional plant，machinery or pre一constructed units or parts of units of work over part of a highway or bridge，the moving whereof is likely to damage any highway or bridge unless special protection or strengthening is carried out，then the contractor shall before moving the load on to such highway or bridge give notice to the engineer or engineer's representative of the weight and other particulars of the load to be moved and his proposals for protecting or strengthening the said highway or bridge．unless within fourteen days of the receipt of such notice the engineer shall by counternotice direct that such protection or strengthening is unnecessary，then the contractor will carry out such proposals or any modification thereof that the engineer shall require and，unless there is an item or are items in the bill of quantities for pricing by the contractor of the necessary works for the protection or strengthening aforesaid，the costs thereof shall be paid by the employer to the contractor．
30．2如承包人必須經部分公路或橋樑一次或多次運送建築設備、機械或工程預製件或預製部件，如不採取特殊保護和加固措施，此種運送很可能損壞公路或橋樑，承包人運送貨物通過此公路或橋樑前必須通知工程師或工程師代表，告之運送貨物的重量及其他具體情況，以及其擬對上述公路或橋樑採取的保護和加固措施。除非在接到通知14天內，工程師以取消通知的方式指示不必採取此種保護或加固措施，承包人將施行此種方案或施行經工程師要求修改後的方案，除非建築工程清單中含有一項或多項已由承包人標價的上述公路或橋樑保護或加固的必要項目，其費用得由業主向承包人支付。
