Construction Management

How does the sustainability concept of integration affect the construction

process and the CM/GC’s role?

On a green project, all of the different components of the construction process and the building are interconnected. The CM/GC must

follow existing best practices, incorporate green elements into the project, help owners understand trade-offs, and make sure that the project is built

to be as green as possible.

1 CONSTRUCTION MANAGEMENT AND GREEN BUILDINGPage 4

What is the CM/GC’s role on the Sustainability Team (ST)?

The CM/GC will be an active member of the Sustainability Team and coordinate the activities and involvement of his or her group or

company.

2 PRE-CON SERVICES: SUSTAINABILITY PLANNING IN THE DESIGN PHASE Page 11

How is the CM/GC involved in identifying sustainability

goals and target LEED credits?

The CM/GC reviews the schematic plans, gives advice on how sustainability measures impact

construction costs and schedules, evaluates the A/E team’s proposed product selection, and

reviews specifications and checks with suppliers and manufacturers to confirm the constructability

and cost of the project.


Why and how do you conduct and evaluate a simple payback

analysis?


A simple payback analysis compares the first costs of an improvement to the savings that will result form the improvement. For each measure,

• First calculate the additional cost (if any) of the proposed upgrade to the base design Additional Cost of the Upgrade

• Subtract the amount of any available Incentive or Subsidy to get the Net Capital Investment

• Calculate the Anticipated Annual Operational Savings • Divide by the Additional Cost of the Upgrade to get

the Payback Period

What is the CM/GC's role in analyzing sustainability

incentives?CM/GC’s role is to assist and provide

valuable input – conduct a thorough review of incentives and rebates specific to each project, which will identify all the funding

options available and connect them with the relevant green measures being proposed,

and provide various groups with information and the appropriate documentation.


What elements should you include in your Sustainability Management Plan?

The Sustainability Management Plan should include LEED credit

information, CM/GC action steps by project phase, trades affected, and required documentation and work

practices.

3 SUSTAINABILITY MANAGEMENT PLANPage 15

When updating your Sustainability Management

Plan, what critical elements need to be confirmed?

The Sustainability Management Plan must be updated to address any changes

in scope that arose from the pre-con evaluations and assessment. Include all

items that impact the schedule, purchasing, or coordination.

3 SUSTAINABILITY MANAGEMENT PLANPage 15

What should the CM/GC consider when selecting

green subcontractors?

• Prior experience and track record with green work

• Green certifications or training• An interest in learning about green work• Ability to identify alternative products

that are more green• Where their operations are located

4 TRADE BID AND AWARD: INCORPORATING SUSTAINABILITY STRATEGIES Page 18

What are the unique elements of bid documents on a green

project?

• An overview of the project’s sustainability goals.• Provide the LEED credit scorecard, with a narrative

explaining what documentation and work-practices will be required of the contractors, and template letters showing which information subcontractors will be required to submit

• Individual scopes of work that includes appropriate green language and each trade’s LEED credits


How does the vetting of green bids differ from standard practice?

Vetting of green bids will now include the sustainability goals,

green construction elements, and any special circumstances and

methods of installation.


What is the intent of each of the four core sustainable construction

activity areas? 1. CAPP: To reduce pollution from construction activities

by controlling soil erosion, waterway sedimentation, and airborne dust generation.

2. CWM: To divert construction and demolition debris from disposal in landfills and incinerators.

3. CIAQ: To reduce indoor air quality problems resulting from the construction or renovation process.

4. Cx: To verify that the building’s energy-related systems are installed, calibrated, and perform according to the OPR, basis of design, and construction documents.

5 MOBILIZATION Page 23

What are the CM/GC’s primary compliance considerations for

each core area?1.CAPP: Develop your ESC Plan, inform subs of their roles, do

inspections, keep a log of problems and solutions. 2.CWM: Develop your CWM plan, determine a sorting procedure,

motivate subs to minimize waste, obtain weekly percentages of materials diverted, provide documentation to the LEED consultant.

3.CIAQ: Develop your CIAQ plan, respond to local regulations, ensure ventilation, protect HVAC equipment, allow time for flush-out, document the process for LEED and the CxA.

4.Cx: Ensure that equipment conforms with the specs, manage LEED submittals, coordinate start-up field testing, develop O&M manuals, coordinate O&M.

5 MOBILIZATION Page 23

Why is it important to train your trades on project

goals and requirements?Choices in one area of the building can

have an impact on the success of a green measure in another area.

Ensuring that all trades understand this will help to control costs in the long run

and ensure sustainability goals are satisfied.

6 PREPARING YOUR TRADES—PROJECTGOALS AND REQUIREMENTS Page 31

What are the primary green training issues for all trades?


• IAQ and VOCs • Materials storage• Waste reduction • Cx process• How to collect and provide

documentation • Green sequence of installation issues• Recycled & regional materials

Which sustainable strategies can be classified as construction

process activities?


The construction process-specific issues that all trades need to

understand are encompassed within CAPP, CWM, CIAQ, and Cx.

What green issues must the CM/GC track in each work area

as the project proceeds?• Excavation/demolition: Monitor compliance with the ESC,

ensure the use of low-sulfur fuel• Formwork: Confirm FSC wood requirements, reuse formwork,

comply with IAQ, watch out for complications• Foundation: Monitor and control concrete washout• Steel: Use recycled content, regional content• Concrete: Use recycled content, regional content• Envelope: Confirm requirements for sustainable envelope,

façade, and roof systems, verify sealing of joints, overlaps, corners, cutouts, and penetrations for both energy efficiency and water control, ensure VOC compliance, comply with CWM Plan


Is the shop drawing submittal process different on a green job?

If so, how?

The shop drawing submittal and approval process on a green project should be the same

as on a conventional project. The process should be fully integrated with your standard procedures. Project architects and engineers

should have incorporated all of the green requirements into the plans and specifications.

7 SHOP DRAWINGS AND SUBMITTALS Page 33

What types of additional documentation are required from

the CM/GC and your subs?Subcontractors and vendors will be required

to fill out compliance sheets and submit certification letters with product submittals. The CM/GC is required to track and verify that all green specification items and work

practices have been satisfied. It is essential to have a proper paper trail.


What products require additional documentation to verify sustainable

specification conformance?

WaterSense labeling on selected products, ENERGY STAR

products, FSC-certified wood products.


What green elements require CM/GC tracking and verification

at rough-in?

8 ROUGH-IN, FINISHES AND FIT-OUTPage 36

Green elements that require tracking and verification

at rough-in include:•Heat recovery systems•High-efficiency toilets•High-efficiency lighting fixtures•Proper ventilation to protect workers•Compliance with CWM plan

How do you use your Quality Control Plan to be sure that you

are catching all the issues?

The Quality Control Plan includes all the sustainability-related issues identified in the Sustainability Management Plan. Use it as a supplement to standard

management practices to maintain focus on sustainability goals.


What are the primary green issues the CM/GC must watch out for at

the finishes and fit-out stage?


• Review the installation sequence with floor-by-floor site

logistics • Ensure on-site storage of porous materials• Provide ductwork protection per SMACNA standards• Confirm all openings in piping are sealed until start-up• Confirm VOC-emitting finishes meet green specifications• Ensure proper ventilation when pollutants are unavoidable• Coordinate building flush-out with subs and the CxA• Confirm HVAC controls and BMS meet product specifications• Confirm electrical and plumbing systems meet specs

Which building systems require the CM/GC's involvement in the

commissioning process?

For the CM/GC, the commissioning process involves attention to the HVAC&R systems

(mechanical and passive), plumbing, lighting and day-lighting controls, greywater and

blackwater recycling systems, fire-protection systems and renewable energy systems.

9 COMMISSIONING AND CLOSE-OUTPage 42

How is the CM/GC's role different with Enhanced as opposed to Fundamental Commissioning?

On projects that include Enhanced Commissioning, requirements are expanded

to include additional documentation of the commissioning review process, review of

contractor submittals, verification that operation personnel are trained, and review

of systems operation after occupancy.


What are the CM/GC's roles in commissioning at the various

stages of construction?• Design Review - Assist in value engineering, provide support

developing the Cx plan, provide relevant submittals and shop drawings for review

• Construction Inspections and Performance Testing - Arrange for installation, pre-functional, and start-up inspections, ensure subcontractors complete CxA punch lists and corrective work, coordinate with CxA on final testing and acceptance procedures

• O&M Training Supervision and Turnover - Assist in development of O&M manuals to ensure optimal future systems operation, develop and deliver operations training program for the owner’s O&M staff, system troubleshooting


What types of green-related documentation must the CM/GC provide at project

close-out?

The CM/GC must obtain, organize and provide the required documentation from

the subcontractors at project close, especially material reporting templates

required for LEED.


Describe the different options available for M&V in the IPMVP

published by EVO.• Description of the energy efficiency measures to be implemented• Selection of the IPMVP options and boundaries of the systems to

be evaluated• Selection of the baseline and reporting period• Identification of routine adjustments, such as those caused by

changes in weather• Identification of non-routine adjustments , such as changes in

facility use• Selection of which meters will be used or needed, including utility

and vendor meters, and additional, equipment specific meters

10 MEASUREMENT AND VERIFICATIONPage 50

Describe how energy efficiency is predicted and measured in the

construction of a new building versus a retrofit.

A retrofit can take the water and energy usage history from utility meters and compare

those to new levels after a sustainability measure is introduced, while a new building must compare those savings to how much

would be used had the building been constructed using standard techniques


Describe the value of a Post-Occupancy Review and

Assessment.

It provides a method for comparing the actual outcomes of the project

to its stated goals, and to extract the root causes that led to its successes

and failures.
