Construction vs Manufacturing Process Construction Process Manufacturing Process NatureService-orientedProduct-based Quantity of Production Single and unique product Mass/batches of units Target PurchaserClients who need a facility Without designated purchaser FocusPlanning and controlling resources within the timeframe of project Applying resources over the life of extended production run of many unit

Construction and Manufacturing Process Manufacturing Process Construction Process Design and Fabricate units Units in inventory Distribute units for sale Preliminary Design Final DesignConstruction

Sequence of Project Development Three parties 1. Owner : who needs for a facility 2. Designer : who designs the facility on the basis of owner’s need 3. Constructor : Contractor, who constructs the facility on the basis of the design

Sequence of Project Development Owner shows a need for the facility Designer carries out feasibility studies and cost estimations Obtain a conceptual design and approximate cost estimate Proceed with detailed design Advertising project Acceptance of proposal and construction commenced Project testing and maintenance of the facility

Construction Technology and Management Technology techniques used to place physical materials and elements of construction Management 4M resources: manpower, machines, materials and money Construction manager should consider optimum application of 4M resources, should also consider quality, time and money constraints

Structure of Construction Industry Building Habitational, institutional, educational, commercial, social, recreational, office building, shopping centers, sports complexes Engineered Highways Project and Heavy Project Industrial Highly technical projects in product manufacturing and processing

Preparing the bid package Establishing Need Establishment of a need of certain facility for users Social needs? Economic needs? Need Evaluation Cost/benefit analysis Graphical representation of the project and a layout diagram Cost estimate based on the conceptual-level information available

Conceptual Drawings and Estimates Cost/benefit analysis, layout drawings, 3D models Cost estimate: conceptual drawing Estimate based on specific cost indexes

Design of a facility Preliminary design General layout, floor plan, building cladding, finishing, heating system, foundation support, structural frame Detailed design Gives a detailed design to ensure the design is within owner’s financial resources and to evaluate bids
