背景资料
某机电安装工程公司承接一汽车厂重型压力机车间机电设备安装工程，工程内容包括设备建造、压机的就位安装、压力管道安装、自动控制工程、电气工程和单机试运行等。其中压机最高22.5m，单件最重为105t。合同工期为4个月。合同约定，工期每推迟一天罚10000元，提前一天奖励5000元。
该公司项目部对承接工程进行分析，工程重点是压机吊装就位，为此，制定了两套压机吊装方案。第一套方案，采用桅杆式起重机吊装，经测算施工时间需要50天，劳动力安排日平均为30人，参照相关定额预算人日平均工资50元，机械台班费及新购置钢丝绳和索具费用共20万元，其他费用2.5万元。第二套方案，采用两台100t汽车式起重机抬吊，但需要租赁，机械租赁费用1万元/日?台。经测算，现场共需14天，与第一套方案相比人工费可降低70%，其他费用可降低30%。
该项目部台理选择了吊装方案，注重安全管理，合理调度。加强了各阶段的成本控制，尤其对压机吊装成本费用控制很严。吊装队发挥了积极性，如期完成任务，为后面工序创造了良好条件，使该工程项目提前8天完成了施工任务。
该工程项目应编制何种类型施工组织设计和专项施工方案?
