Three changes in design, bidding, procurement and construction

The expressed needs of customers can be achieved by ordinary designers, but tapping the potential needs of customers requires long-term communication and understanding of front-line technicians

The specific methods are as follows: collect, guide and tap all the needs of customers, share engineering experience and knowledge, learn, study and improve the understanding of products with relevant parties; Decompose the composition of products, confirm the industrialized parts and components with clear customer needs, guide customers to quickly find the needs with a large number of knowledge bases, databases and picture bases, and turn the standard data, graphics and pictures of the needs, so as to quickly narrow the design boundary and improve the design effectiveness; At the same time, the enterprise’s platform resource library quickly supports the parts of professional design, such as curtain wall, hardcover, elevator, intelligence, lighting, garage and logo, which are fully involved in the construction drawing design stage; The parameters and models of industrial spare parts such as doors and windows, fire shutter and electromechanical equipment shall be determined in the construction drawing design stage, and even the bidding and procurement shall be completed in advance

.

The core is to achieve positive design guided by the expressed and potential needs of end customers (users)

.

Through the whole process of customer communication of thousands of projects in China over the past few decades, the company’s markets have mastered the demand culture and potential demand points of different user groups across the country for public buildings, houses, factories, infrastructure, etc., which provides the core competitiveness for the development of the company, especially the drawing changes and customer demand analysis and sorting of thousands of projects by the company’s technical center, A set of standards and implementation guidelines for drawing deepening and optimization has been formed, which has continuously improved the construction capacity of Nantong Second Construction Co., Ltd

.

In terms of improving the comprehensive capacity of bidding and procurement, the transformation from “ensuring progress and quality” to “affecting design, reducing cost and increasing efficiency” is the key to the connection between design and construction and an important link in the implementation of design

.

In the previous design process, due to the lag of bidding and procurement, the information stickiness between designs, and the uncertainty of equipment and materials, the design mostly adopts the general atlas, general dimensions and architectural instructions for preliminary functional design, dimension determination and structural practices, especially the special parts are more marked as “deepened by professional manufacturers” Remarks such as “detailed design of bidding and procurement by the owner alone”.

.

The main path is to decompose the functions of building and installation, communicate in an all-round, whole process and full cycle, and guide customers to express and clarify their potential needs, so as to unify the goal consistency of all parties through grass-roots, middle-level and high-level communication, early-stage in-depth communication between designers, constructors, builders, terminal owners and property, Improve the depth of understanding of products and services, improve everyone’s cognitive ability, gradually display the building functions and requirements on the drawings and lists, gradually reduce the boundary conditions, melt the professional interface, and realize the positive design with the data and image of the final effect, so as to achieve the minimum drawing changes through the implementation of EPC project

.

In terms of the improvement of design management ability, the transformation from “deepening design and optimizing design” to “leading design and managing design” compared with the general construction contractor or civil engineering general contractor, the original work on the review, joint review, drawing deepening and optimization of construction drawings has clear boundary conditions, and only suggestions on modification of the design within the scope of contract are put forward, Design modification and change for insufficient drawing depth and design quality; However, we basically lack the right to speak and influence on how to realize customer demand-oriented design changes

.

The original construction mode is the process of conceptual design – scheme design – initial expansion design – construction drawing design – professional subcontracting design – bidding and procurement design – manufacturer’s industrial design – construction and installation – delivery – property maintenance, resulting in that the final customer needs can not be mastered due to many management interfaces, and some can be realized through change, modification and improvement after delivery, However, some functional requirements cannot be realized after delivery, and the waste of cost and construction period is serious

.

Through the scientificity and rationality of design, the use of imported components and accessories, non-standard components and accessories and high value components and accessories can be avoided

.

Different from the general construction contract, the general engineering contract is not only the expansion and extension of the project management stage and scope, but also the great change of the role and responsibility undertaken by the general contractor, which means the systematic transformation of thinking mode, management system and project management mechanism

The improvement of the comprehensive ability of bidding and procurement is not only the efficient procurement process and the advanced procurement platform, but also the systematic evaluation of professional construction teams, professional manufacturers, professional equipment and professional materials and the accumulation of knowledge database

.

Therefore, our current EPC project has realized the transformation of “leading design and managing design”

.

has accumulated relevant suppliers for many years, including the upstream product chain of professional subcontracting teams and professional manufacturers, and has organized the data resource database accumulated by supplier evaluation for years, which provides support for the improvement of comprehensive bidding and procurement capacity

.

Therefore, it is very important to improve the comprehensive capacity of bidding and procurement

.

The advance selection of professional team can intervene in the design and the construction of the previous process earlier, which is conducive to submitting clear interface requirements and contents; The detailed design and determination of professional equipment and materials can provide support for the determination of civil engineering parameters, such as the required size of auxiliary space for standby “rooms, rooms, wells, corridors, ditches and pits” to avoid waste

.

Even the engineering construction industry is the hardest hit area of anti-corruption

.

Through the provision of bidding and procurement information in the design stage, provide targeted design boundaries and design parameters, compress the design cycle and improve the timeliness and effectiveness of the design

.

Scheme design, construction drawing design and professional deepening design all need the concretization of the design object

.

and the service capacity of EPC project

.

has eight customer relationship communication lists in the maintenance stage: Master customers’ expectations and preferences through customers’ requirements for maintenance, understand use needs through visits, questionnaires and return visits, invite customers and property to participate in post project evaluation, satisfy customers, and put forward improvement suggestions for bidding operation and drawing optimization and deepening; In the marketing stage list, deeply understand the customer culture and find out the potential needs of customers; In the forty items of the customer relationship list, we will dig deep into the customer relationship from the five stages of marketing, bidding, construction, delivery and maintenance, so as to improve products and services

.

at the same time, if the bidding and procurement is too early, its price fluctuation will have a great impact on the construction cost, In the past, bidding and procurement realized the economy of bidding and procurement content on the premise of ensuring progress and quality standards; For EPC project general contracting, bidding and procurement need to pay more attention to the economy of comprehensive construction cost

.

Often, many highly professional construction parties and equipment and materials can enter the stage of construction drawing deepening only after the bidding and procurement are determined, such as large customized equipment, distribution boxes and cabinets, mechanical garage, purification space, etc

.

The more specific it is, the more conducive it is to the determination and solidification of the cost

.

According to years of construction practice, we have common goals with large and mature real estate developers in understanding design functions, but for projects such as particularity, public projects and infrastructure, due to interface problems in objectives, interests, information and culture, design, bidding, procurement The contradiction between the technical interface and the management interface between the construction is prominent and the information is sticky, so it is difficult to build products and services that are very satisfactory to all interested parties

The key to the improvement of comprehensive bidding and mining capacity is to reduce cost and increase efficiency through support design

Now promote EPC from the construction mode, change from “deepening and optimizing design” to “leading design and managing design” from the technical level, and give full play to the role of a comprehensive construction service provider integrated by the general contracting team, which can not only effectively control the construction period and control the project cost, but also maximize the customer demand and create a more scientific, applicable Energy saving and environmental protection building products

.

EPC general contracting does not only deepen and optimize the design, but also lead and manage the design
