Medical Cleanroom Engineering
In the construction of medical cleanroom engineering (such as operating rooms, laboratories, etc.), unclear construction interfaces are a common cause of project delays, cost overruns, and disputes over responsibilities. How can scientific contract planning clarify the rights and responsibilities of all parties and ensure the smooth progress of the project? The key lies in the following core strategies:
01What is Construction Procurement? What is Bidding?
Construction procurement includes engineering activities or services such as the new construction, renovation, expansion, decoration, demolition, and repair of buildings and structures.
The concept of bidding: Bidding is a relatively mature, advanced, and standardized transaction method that applies technical economic evaluation methods and the competitive mechanism of the market economy to conduct organized selection of the best offers.
During a competitive activity, the bidder must publicly announce the bidding conditions in advance, invite specific or non-specific bidders to participate, and select the winning bidder according to the prescribed procedures, aiming to maximize the comprehensive benefits of investment (transaction behavior).
Medical cleanroom equipment is designed to provide clean purposes (air, water, electricity, items, etc.) for medical services or to be free from contamination itself. A system formed by various medical cleanroom equipment is known as medical cleanroom engineering.
The basic characteristics of medical cleanroom equipment and medical cleanroom engineering include effectively achieving expectations, safe use, controlled environment, and being more economical and energy-efficient than conventional systems.
Medical cleanroom equipment includes but is not limited to air conditioning and purification systems, and is not just a single device. These devices need to be used in conjunction to form an equipment engineering system, which requires effective coordination and operation without counteracting effects. A typical example of medical cleanroom engineering is a clean operating room. Various clean operating rooms have specific requirements for clean equipment, and the general environment also demands distributed clean equipment.
02Contract Planning in Bidding (Procurement)
This phase of contracting and bidding (procurement) management includes most of the management work for the implementation of purification projects, excluding the management of survey and design bidding.
Contract Planning Phase, Mainly for Contracting and Procurement
This phase of contracting and bidding (procurement) management includes bidding activities for engineering, consulting services, and materials and equipment. Among them,engineering bidding includes general contracting and designated specialized subcontracting (such as clean operating rooms, ICUs, CCUs, NICUs, intravenous preparation centers, etc.);service bidding includes designated professional design, construction supervision, bidding agency, cost consulting, project valuation, monitoring or testing, and other consulting services; material and equipment procurement includes materials and equipment supplied by the owner.
Contract Structure, Contracting Interfaces, Contracting Methods
The contract structure, contracting interfaces, and contracting methods in this phase are the focus of contract planning in the early stages and planning phase of the project.Determine the contract structure and clarify each contracting interface to avoid omissions, prevent duplication, and facilitate management and handover of the project.Based on relevant regulations from the national and local governments, combined with the characteristics of the project and contract structure, determine the contracting method.
The overall time plan for contracting and bidding (procurement) work requires reasonable preparation time for the project to align with the overall construction plan, ensuring the smooth progress of the project.Based on the overall construction plan of the project, develop a contracting work plan for the construction preparation phase.According to the contracting method and work plan, develop a specific time plan, including the timeline for various activities during the contracting and bidding (procurement) process.Check the implementation of contracting and bidding (procurement) work and compare it with the corresponding progress plan, making timely adjustments to deviations to ensure the smooth progress of the entire project.
03Qualification Pre-Assessment for Bidding Units
It is possible to require the bidding agency to organize a qualification pre-assessment and monitor the entire process. The specific implementation method isto participate in the qualification pre-assessment expert review meeting,master the summary of qualification pre-assessment results, and determine the shortlisted candidates.
Participate in on-site inspections and Q&A meetings.It is possible to require the bidding agency to organize on-site inspections and hold Q&A meetings, and monitor the entire process.Participate in the on-site inspection activities of bidding units and related units at the agreed time and place, and introduce the on-site situation.Within the agreed time, participate in answering written questions raised by bidding units during the inspection and preparation of bidding documents.Participate in the Q&A meeting.
04Bidding Work Must Organize the Preparation and Review of Bidding (Procurement) Documents
The main content of the review of bidding (procurement) documents includes:whether the bidding (contracting) scope is correct;whether the subcontracting (if needed) scope is correct; the engineering bidding content scope should correctly describe and define the engineering quantity and boundaries, work content, and surrounding division, coordination, and boundary conditions; the division of engineering bidding sections needs to consider major factors such as laws and regulations, engineering contracting management models, engineering management capabilities, bidding qualifications and competitiveness, engineering technology, measurement and interface relevance, construction period, and scale.
If the cleanroom engineering is divided as a subcontracting project, the division of construction interfaces is particularly important. Clearly delineating the construction boundaries of the cleanroom engineering is essential for clear construction and responsibility allocation.
Decoration and Renovation
All decoration and finishing within the red line area, including walls, ceilings, floors, embedded medical equipment, internal doors, internal windows, and lead protection, as well as the finishing work at construction boundary interfaces; coordinate with the fire protection system to complete the positioning, opening, and finishing work of terminal equipment. The boundary interface doors (except for stairwells, pipe shafts, and stair lobbies) are to be completed by the purification unit with waterproofing, leveling, and DSA barium sulfate cement.

The total package provides the incoming cable for the double cut box. The total distribution box for DSA large medical equipment and the distribution after the pile head. Provide purification area UPS equipment and incoming and outgoing lines. Lay weak current cable trays to related weak current wells and their procurement, installation, commissioning, and acceptance. The corridor fire broadcast is constructed by the building’s weak current unit. Complete the automatic control of the ventilation and air conditioning system constructed and be responsible for the procurement, installation, commissioning, and acceptance of related equipment and materials.
Weak Current System
Complete the monitoring system, integrated wiring system, call system, etc., within the red line area, with weak current lines reserved to the weak current well from the reserved valve (after the compressed air secondary pressure reduction box, after the negative pressure suction gauge valve box).
Medical Gas System
Procurement, installation, and commissioning of gas pipelines, terminals, fittings, and carbon dioxide manifold systems from the start to the purification bidding scope. Procurement, installation, construction, and commissioning of all water supply pipelines, sanitary ware, and related fittings from the reserved valve to the red line area.
Water Supply and Drainage System
Pipeline connection between drainage facilities and drainage riser access points. The anchor bolts for the suspension towers at each bed position and the shadowless lamp anchor bolts are to be installed free of charge by the purification unit in cooperation with the construction unit, with the suspension towers and shadowless lamp equipment supplied by the owner.
Typical models include: “Design + Build” (D+B), “Design Procurement Construction” (EPC), and “Factory Equipment with Design + Construction”.
This is generally applicable to large-scale construction projects with strong professional technicality, complex management coordination work, and where the bidder has weak management capabilities over design and construction, and is willing to transfer most risks to a contractor. It is beneficial for the coordination between engineering design and construction, avoiding errors, omissions, changes, rework, and disputes caused by disconnection; it allows for reasonable organization of segmented design and construction, shortening the construction period. However, the bidder has less influence over the details of engineering design and construction, so it is crucial to select a general contractor with high professional quality in design and construction and comprehensive coordination management capabilities through bidding, and to clearly define relevant responsibilities and risks.

It is required that bidding units establish a BIM model for the designed content, scope, and process.It is necessary to review whether the qualifications of the bidding units comply with relevant regulations and the characteristics and needs of the project itself.It is necessary to review whether the technical and quality standards, technical requirements, and progress requirements meet project requirements.
It is essential to comprehensively and accurately analyze and grasp the functions, characteristics, and conditions of the purification operating room project, and to scientifically and reasonably set the quality, cost, progress, safety, and environmental management requirements of the engineering project based on relevant laws, standards, specifications, project approvals, design documents, and implementation plans.The schedule of bidding activities should comply with the overall schedule requirements of the project.The attached contract (if any) clauses should meet the requirements of the construction unit and project objectives.The evaluation method should be scientific, fair, reasonable, and suitable for the nature of this project.
Organize the preparation and review of the bill of quantities or bidding control price documents.Review whether the drawings and specifications meet technical requirements.Review whether the requirements for major equipment in the bill of quantities (model, specification, brand) meet the requirements.
Compare the major items (civil engineering, installation engineering) in the control price with the budget indicators. If there is a significant difference, request clarification from the bidding control price preparation unit.Organize the bidding agency to prepare the bill of quantities or bidding control price documents.Review the bill of quantities or bidding control price documents, focusing on interface division, omissions, or sub-projects that have a significant impact on costs.The opening and evaluation activities includethe opening and evaluation meetings,and determining the winning bidder based on the evaluation report.
05Organize the Drafting and Review of Engineering Contract
Assist the construction unit and organize the bidding agency to draft the engineering contract.Review the engineering contract, focusing on clauses related to investment, progress, quality, and safety.
06Participate in Contract Negotiation and Signing
From the perspective of fairly maintaining the construction project, coordinate to resolve disputes over contract clauses, which is beneficial for the smooth implementation of the contract.
The content of contract negotiations mainly includesthe scope of work, work content, engineering quantity, and interface division with other participants;the rights, responsibilities, and obligations of both parties;contract price, pricing form, and adjustment methods;quality requirements and acceptance methods and procedures for the contract subject;progress requirements for the contract subject and cooperation work of other participants;provisions for engineering changes and additions;establishment of liability for breach of contract and dispute resolution methods.
Should participate in contract negotiations and record the negotiation content.Should participate in the contract signing work and pay attention to the legality of the contract signing procedures.Master the local government department’s regulations on contract filing, and submit relevant materials for filing within the date specified by the local government department.
The high standards of medical cleanroom engineering leave no room for disputes! Through pre-contract planning, detailed interface management, and the empowerment of technical tools, we can completely eliminate the responsibility vacuum, allowing projects to be efficiently implemented and all parties to win.
