公路工程基本建设项目的划分及其意义?

一、建设项目是由许多部分组成的,依次可以划分为:建设项目、单项工程、单位工程、分部工程和分项工程。

1、建设项目

建设项目又称基本建设项目,能独立发挥生产功能或满足生活需要,其项目建议书经批准立项和可行性研究报告经批准的建设任务。如交通基础设施中的一条公路,一座独立大、中型桥梁或一座隧道等均为一个建设项目。

2、单项工程

单项工程又称为工程项目,它是建设项目的组成部分,是具有独立的设计文件,在竣工后能独立发挥设计规定的生产能力或效益的工程。公路建设的单项工程一般指独立的桥梁工程、隧道工程,这些工程一般包括与已有公路的接线,建成后可以独立发挥交通功能。但一条路线中的桥梁或隧道,在整个路线未修通前,并不能发挥交通功能,也就不能作为一个单项工程。

3、单位工程

单位工程是单项工程的组成部分,它是指单项工程中可单独进行设计,可以独立组织施工,并可单独作为成本计算对象的部分。公路建设项目一条公路中把一段路线作为一个单项工程,其中各个路段的路基、路面、桥梁、隧道都可作为单位工程。

4、分部工程

在公路建设工程中,分部工程的确定是在工程项目界定的范围内,以工程部位、工程结构和施工工艺为依据,并考虑在工程建设实施过程中便于进行工程结算和经济核算的方便。如按工程部位划分为路基工程、路面工程、桥涵工程等,按工程结构和施工工艺划分为土石方工程、混凝土工程、砌筑工程等。

5、分项工程

分项工程是分部工程的组成部分,是根据分部工程划分的原则,再进一步将分部工程分成若干个分项工程。它是概预算定额的基本计量单位,故也称为工程定额子目或称工程细目。如路基土石方分为松土、软石等各类土石成分,基础砌石分为片石、块石等

二、公路工程项目划分的意义

在工程施工阶段,施工单位应依据已划分好的分项工程按基本要求、实测项目和外观鉴定进行自查,按“分项工程质量检验评定表”提交真实、完整的自查资料,对工程质量进行自我评分、并及时进行分部项目工程质量评定,要完成一个分部工程就评定一个分部工程。监理单位应及时对施工单位已完成的分项工程进行抽查并检查施工单位的质量保证施工质量保证资料,及时对分项工程和分部工程进行评定,并进行计量支付。

工程竣工后,施工单位应及时进行单位工程评定和建设项目评定。监理单位应对工程整体验收后进行单位工程和建设项目的评定,要对施工自查资料进行签认和评分,写出评述报告,报监理部门备案。质量监督部门根据抽查资料和确认的施工自查资料以及监理工程师的质量管理资料对工程质量进行逐级评定,并作为交、竣工验收评定质量等级的依据。

第二篇:工程建设项目分类

工程建设项目分类

由于工程建设项目种类繁多,为了适应科学管理的需要,正确反映工程建设项目的性质、内容和规模,可从不同角度对工程建设项目进行分类。

1.按建设性质划分

基本建设项目可分为新建项目、扩建项目、迁建项目和恢复项目。

(1)新建项目。

是指根据国民经济和社会发展的近远期规划,按照规定的程序立项,从无到有、“平地起家”的建设项目。现有企、事业和行政单位一般不应有新建项目。有的单位如果原有基础薄弱需要再兴建的项目,其新增加的固定资产价值超过原有全部固定资产价值(原值)3倍以上时,才可算新建项目。

(2)扩建项目。

是指现有企业、事业单位在原有场地内或其他地点,为扩大产品的生产能力或增加经济效益而增建的生产车间、独立的生产线或分厂的项目;事业和行政单位在原有业务系统的基础上扩充规模而进行的新增固定资产投资项目。

(3)迁建项目。

是指原有企业、事业单位,根据自身生产经营和事业发展的要求,按照国家调整生产力布局的经济发展战略的需要或出于环境保护等其他特殊要求,搬迁到异地而建设的项目。

(4)恢复项目。

是指原有企业、事业和行政单位,因在自然灾害或战争中使原有固定资产遭受全部或部分报废,需要进行投资重建来恢复生产能力和业务工作条件、生活福利设施等的建设项目。这类项目,不论是按原有规模恢复建设,还是在恢复过程中同时进行扩建,都属于恢复项目。但对尚未建成投产或交付使用的项目,受到破坏后,若仍按原设计重建的,原建设性质不变;如果按新设计重建,则根据新设计内容来确定其性质。

基本建设项目按其性质分为上述四类,一个基本建设项目只能有一种性质,在项目按总体设计全部建成以前,其建设性质是始终不变的。

更新改造项目包括挖潜工程、节能工程、安全工程、环境保护工程等。

2.按投资作用划分

工程建设项目可分为生产性建设项目和非生产性建设项目。

(1)生产性建设项目。是指直接用于物质资料生产或直接为物质资料生产服务的工程建设项目。主要包括:

1)工业建设。包括工业、国防和能源建设;

2)农业建设。包括农、林、牧、渔、水利建设;

3)基础设施建设。包括交通、邮电、通信建设,地质普查、勘探建设等;

4)商业建设。包括商业、饮食、仓储、综合技术服务事业的建设。

(2)非生产性建设项目。是指用于满足人民物质和文化、福利需要的建设和非物质资料生产部门的建设。主要包括:

1)办公用房。国家各级党政机关、社会团体、企业管理机关的办公用房;

2)居住建筑。住宅、公寓、别墅等;

3)公共建筑。科学、教育、文化艺术、广播电视、卫生、博览、体育、社会福利事业、公共事业、咨询服务、宗教、金融、保险等建设;

4)其他建设。不属于上述各类的其他非生产性建设。

3.按项目规模划分

为适应对工程建设项目分级管理的需要,国家规定基本建设项目分为大型、中型、小型三类;更新改造项目分为限额以上和限额以下两类。不同等级标准的工程建设项目国家规定的审批机关和报建程序也不尽相同。划分项目等级的原则如下:

(1)按批准的可行性研究报告(初步设计)所确定的总设计能力或投资总额的大小,依据国家颁布的《基本建设项目大中小型划分标准》进行分类。

(2)凡生产单一产品的项目,一般按产品的设计生产能力划分;生产多种产品的项目,一般按其主要产品的设计生产能力划分;产品分类较多,不易分清主次、难以按产品的设计能力划分时,可按投资总额划分。

(3)对国民经济和社会发展具有特殊意义的某些项目,虽然设计能力或全部投资不够大、中型项目标准,经国家批准已列入大、中型计划或国家重点建设工程的项目,也按大、中型项目管理。

(4)更新改造项目一般只按投资额分为限额以上和限额以下项目,不再按生产能力或其他标准划分。

(5)基本建设项目的大、中、小型和更新改造项目限额的具体划分标准,根据各个时期经济发展和实际工作中的需要而有所变化。现行国家的有关规定如下:

1)按投资额划分的基本建设项目,属于生产性建设项目中的能源、交通、原材料部门的工程项目,投资额达到5000万元以上为大中型项目;其他部门和非工业建设项目,投资额达到3000万元以上为大中型建设项目;

2)按生产能力或使用效益划分的建设项目,以国家对各行各业的具体规定作为标准;

3)更新改造项目只按投资额标准划分,能源、交通、原材料部门投资额达到5000万元及其以上的工程项目和其他部门投资额达到3000万元及其以上的项目为限额以上项目,否则为限额以下项目。

(6)一部分工业、非工业建设项目,在国家统一下达的计划中,不作为大中型项目安排:

1)分散零星的江河治理、国营农场、植树造林、草原建设等;原有水库加固,并结合加高大坝、扩大溢洪道和增修灌区配套工程的项目,除国家指定者外,不作为大中型项目;

2)分段整治,施工期长,安排有较大伸缩性的航道整治疏浚工程;

3)科研、文教、卫生、广播、体育、出版、计量、标准、设计等事业的建设(包括工业、交通和其他部门所属的同类事业单位),新建工程按大中型标准划分,改、扩建工程除国家指定者外,一律不作为大中型项目;

4)城市的排水管网、污水处理、道路、立交桥梁、防洪、环保等工程城市的一般民用建筑包括集资统一建设的住宅群、办公和生活用房等;

5)名胜古迹、风景点、旅游区的恢复、修建工程;

6)施工队伍以及地质勘探单位等独立的后方基地建设(包括工矿业的农副业基地建设);

7)采取各种形式利用外资或国内资金兴建的旅游饭店、旅馆、贸易大楼、展览馆科教馆等。

4.按行业性质和特点划分

根据工程建设项目的经济效益、社会效益和市场需求等基本特性,可将其划分为竞争性项目、基础性项目和公益性项目三种。

(1)竞争性项目。主要是指投资效益比较高、竞争性比较强的一般性建设项目。这类建设项目应以企业作为基本投资主体,由企业自主决策、自担投资风险。

(2)基础性项目。主要是指具有自然垄断性、建设周期长、投资额大而收益低的基础设施和需要政府重点扶持的一部分基础工业项目,以及直接增强国力的符合经济规模的支柱产业项目。对于这类项目,主要应由政府集中必要的财力、物力,通过经济实体进行投资。同时,还应广泛吸收地方、企业参与投资,有时还可吸收外商直接投资。

(3)公益性项目。主要包括科技、文教、卫生、体育和环保等设施,公、检、法等政权机关以及政府机关、社会团体办公设施,国防建设等。公益性项目的投资主要由政府用财政资金安排的项目。

5.按管理权限和投资规模划分

中国石油天然气股份有限责任公司,按管理权限和投资规模把建设项目分为限上项目和限下项目。以便实行对投资项目集中决策,股份公司、专业公司和地区公司分级管理。股份公司规划计划部负责限上项目的管理。主要负责组织有关专家对限上项目的项目建议书(预可研)、可行性研究报告进行评审,提出审查意见,经批准后,办理批复文件。需报国家审批的项目,负责向国家有关部门办理立项审批手续,经国家批准后下达;限下项目由专业公司和地区公司实行分级管理。其中3000万元及以上项目的前期论证材料,由专业公司报股份公司规划计划部备案。股份公司管理的限上项目包括:

(1)新申请勘查登记的勘探项目;预探发现储量(控制或预测)规模石油在5000万吨、天然气300亿立方米以上的整装油气田,需转入评价勘探的项目;

(2)动用石油可采储量400万吨(或30万吨/年产)及以上,动用天然气可采储量100亿立方米(或5亿立方米/年产)及以上的开发建设项目;

(3)投资在5000万元以上(含5000万元,下同)的新建、改扩建油气长输管道项目;

(4)新建炼化厂及现有炼油厂扩大一次加工能力的项目;投资在5000万元以上的炼油、化工、天然气化工及配套项目;

(5)油库、加油站销售网络建设总体方案;

(6)利用外资(外汇)贷款项目和合资合作项目;

(7)50万美元及以上的引进项目(含20万美元及以上软件项目);

(8)对外投资项目和楼、堂、馆、所建设项目;

(9)按规定应上报国家计委、国家经贸委和国务院审批的建设项目。

第五篇:河流分类的意义和原则

河流分类的意义和原则

幅员广阔、河流众多的国家,不可能在短期内对其全部河流进行观测,但是,发展经济的规划、设计却迫切需要河流水位、流量变化和水温动态方面的数据。在某一地区内,影响河流特征的气候、土壤、地质地貌条件大致相同,故河流存在着一定程度的相似性。在不同地区内,影响河流特征的各种条件差别很大,河流水文要素的变化规律当然不一样。因此,可以根据现有的河流水文资料进行综合分析,将其要素变化相似的河流,划归一个类型。当规划设计某一缺乏资料的河流时,就可用同类河流的水文变化规律作为参证。

河流分类的原则如下:1)以河流的水源作为河流最重要的典型标志,按照气候条件对河流进行分类;2)根据径流的水源和最大径流发生季节来划分;3)根据径流年内分配的均匀程度来划分;4)根据径流的季节变化,按河流月平均流量过程线的动态来划分;5)根据河槽的稳定性来划分;6)根据河流及流域的气候、地貌、水源、水量、水情、河床变化等综合因素来划分。
