PART 3 EXECUTION

3.1 NATURAL RESOURCE CONSERVATION

Prior to start of construction, Contractor and subcontractor personnel must attend a Natural Resources Training provided by the Government's Biological Monitor. The biological resources education program focuses on:

a. the purpose for resource protection;

b. Contractor identification of sensitive resource areas in the field (e.g., areas delineated on maps and by flags or fencing);

c. environmentally responsible construction practices and protection measures;

d. protocol to resolve conflicts that may arise at any time during the construction process;

e. ramifications of noncompliance;

f. awareness of Guam's natural resources, regulations, water safety and conservation targets.

Do not disturb fish and wildlife. Feeding of feral animals on the installation is prohibited. Do not alter water flows or otherwise significantly disturb the native habitat adjacent to the project and critical to the survival of fish and wildlife, except as indicated or specified.

Non-native invasive species can be purposefully or inadvertently moved with construction equipment, personal protective equipment and hand tools, foot traffic, vehicles and vessels, raw construction materials, and packing materials. Non-native invasive species can become pests and affect the economy, ecology, and human health. It is critically important to be aware of ways to prevent the movement of non-native invasive species and implement best management practices.

To minimize potential impacts to sea turtles, hooded lights must be used for construction and use within sea turtle habitat to the maximum extent practical. Lighting should meet minimum safety, anti-terrorism, and force protection requirements as necessary. Illumination of forest, coastline, or beach will be consistent with security requirements and kept to an absolute minimum including the shielding of lights and directing lighting away from

SECTION 01 57 19.02 Page 2 the water or other wildlife habitat. In-water work of any kind is not permitted during the coral spawning season. The Coral Spawning Season is defined as 21 days prior to, and 21 days following, the full moon in July.

Outside of the coral spawning season, the requirements specified in the following sections apply.

3.1.1 Conservation of Natural Resources

The Contractor must take measures to avoid, minimize and compensate for impacts to natural resources outside the limits of construction as documented in the Preconstruction Survey submittal. Contractor is responsible for clearly marking approved limits of construction using flags, fencing or other visible marking and will ensure the boundary remains in place throughout construction. The Contractor will be responsible for all materials and labor for the restoration/repair of all unauthorized vegetation impacts outside the limits of construction.

3.1.2 Marine Resources Monitoring

Immediately before and during construction activities, the Contractor furnished biologists must monitor for protected marine resources (Endangered Species Act listed species) within as well as outside the project boundaries. The Contractor must ensure all biologists are familiar with all Endangered Species that may occur in and near the project boundaries. Monitors must be on site during all work occurring in marine waters. Monitors must be trained biologists with a minimum of 120 hours of sea turtle monitoring experience. The Contractor is responsible for verbal and written notification of incidents occurring with Endangered Species Act species at the project site. Monitors must record sighting dates, times, behavior of species. Monitors must immediately report to the Contracting Officer any injuries to Endangered Species Act species that occur during all work. The Contractor must provide a written summary (monthly) of turtles or marine mammals that were sighted within proximity to the project area. This summary will include at a minimum: date of sightings, time of sighting, behavior at time of sighting, and a list of in-water activities occurring during the sighting.

The Contractor must notify the Government Biological Monitor immediately if threatened or endangered species are present or suspected at the project site.

3.1.3 Marine Resources Monitoring for in-water construction activities

Preliminary shutdown safety zones corresponding to where sea turtles could be injured or harassed will be established based upon empirical field measurements of pile driving sound levels at the construction site. The sound pressure levels (SPLs) will be monitored on the first day of pile driving to ensure accuracy of contours. Until validation of the harm threshold, no pile driving may occur within 150 feet of sea turtles and no dredging operations shall occur within 150 feet of sea turtles. Safety zones will be re-established to accommodate validated harm threshold and reported to National Marine Fisheries Service (NMFS) with acoustic monitoring data. Monitoring of sea turtle harassment safety zones would be conducted by qualified observers, including two observers for safety zones around each pile driving and dredging site. A qualified observer will have a minimum of one year previous work experience in observing for turtles on previous job sites. Observers will remain continuously alert for protected species starting 60 minutes prior to commencement of pile driving and dredging through 30 minutes after shut-down. Resumption of work following a

SECTION 01 57 19.02 Page 3 break of 30 minutes or more requires a 60 minute pre-work area visual search. If a sea turtle is found within the safety zone, pile driving or dredging of the segment must be halted until the animal(s) has been visually observed beyond the impact zone or 30 minutes have passed without re-detection. No pile driving or dredging will be conducted after dark unless that work has proceeded uninterrupted since at least 1 hour prior to sunset, and no protected species have been observed near the 50-yard safety range for that work.

3.1.4 Special Conditions Relating to Work in or Adjacent to Ocean Water

With the exception of pile driving and dredging, observers must visually survey the project area each day beginning 30 minutes prior to the start of work, and repeated frequently throughout the day.

With the exception of pile driving and dredging, all in-water work must be postponed or halted when protected species are within 150 feet of the proposed work, and must only begin/resume after the animals have voluntarily departed the area.

To the maximum extent possible snorkelers and divers should minimize the use of sunscreens containing chemicals known to be hazardous for marine life such as oxybenzone, butylparaben, octinoxate and 4-methylbenzylidene camphor, and should instead maximize the use of physical sun protection such as long sleeves and headwear.

No in-water blasting will be allowed.

Pile driving and dredging must commence using soft-start or ramp-up techniques, at the start of each work day or following a break of more than 30 minutes. Pile driving must employ a slow increase in hammering, whereas dredging would commence with slow and deliberate deployment of the bucket or excavator to the bottom for the first several cycles to alert protected species and allow them an opportunity to vacate the area prior to full-intensity operations.

If a sea turtle or other listed species is found injured within the vicinity of the action area, all in-water activities must cease immediately, regardless of their effect on the noted turtle and the Government will contact the regional NMFS stranding coordinator.

Construction related vessels within Apra Harbor must remain at least 150 feet from sea turtles, reduce speed to 10 knots or less in the proximity of sea turtles (if practicable, 5 knots or less in areas of suspected turtle activity), and, when consistent with safety practices, put engine in neutral and allow the turtle to pass if approached by a turtle.

Additionally, sea turtles must not be encircled or trapped between multiple construction-related vessels or between construction-related vessels and the shore.

All construction-related equipment must be operated and anchored to avoid impacting sensitive marine habitat or contacting coral reef resources during construction activities or extreme weather conditions. Anchor lines from construction vessels must be deployed with appropriate tension to avoid entanglement with sea turtles. Construction related materials that may pose an entanglement hazard must be removed from the project site if not actively being used. Anchors, anchor chain, wire rope and associated anchor rigging from construction related vessels must be restricted to designated anchoring areas within the construction footprint (i.e., soft

SECTION 01 57 19.02 Page 4 bottom) or within the area that will be permanently impacted.

All vessels should operate at "no wake/idle" speeds at all times while in water depths where the draft of the vessel provides less than a 2 m (6 ft.)

clearance. All vessels should preferentially follow deep-water routes (e.g., marked channels) whenever possible. If operating in shallow water, all vessels should employ a dedicated "lookout" to assist the pilot with avoiding large coral colonies and other benthic organisms that might extend up from the bottom.

In-water construction activities that result in sediment/pollutant discharges (dredging and pile driving) must cease during the primary coral spawning events each year for hard (scleractinian) and soft (octocorallia) corals. Coral spawning seasons for 2021 and 2022 are as follows:

- May 18-June 8, 2021 (Soft Corals)

- July 5-Aug 6, 2021 (Hard Corals)

- May 7-29, 2022 (Soft Corals)

- July 5-27, 2022 (Hard Corals)

Confirm coral spawning seasons with the Contracting Officer prior to starting in-water construction activities.

Construction related vessels will be restricted from Sasa Bay in outer Apra Harbor so as to reduce potential impacts to sea turtles and other protected marine or wildlife species.

Aboard dredge-related tug, barge or scow vessels at sea, must use the minimum lighting necessary to comply with navigation rules and best safety practices to help reduce potential impacts on protected species such as sea turtles.

No one on site or associated with this project must attempt to feed, touch, ride, or otherwise intentionally interact with any protected species.

All project-related materials and equipment placed in the water must be free of pollutants. The project manager and the heavy equipment operator must perform daily pre-work equipment inspections for cleanliness and leaks. All heavy equipment operations must be postponed or halted should a leak be detected, and must not proceed until the leak is repaired and equipment cleaned.

Fueling of construction project related vehicles and equipment must take place at least 150 feet away from the water, preferably over an impervious surface. With respect to construction equipment (e.g., dredging barges and other construction related vessels) that cannot be fueled out of the water, spill prevention booms must be employed to contain any potential spills.

Any fuel spilled will be cleaned up immediately.

Turbidity and siltation from project related work will be minimized and contained through the appropriate use of effective silt containment devices and the curtailment of work during adverse tidal and weather conditions.

Silt curtains will completely enclose dredging and pile driving operations to the maximum extent practicable, to maintain water quality and provide coral protection. If a visible plume is observed outside the silt curtains, construction activity will be suspended, evaluated, and corrective measures taken.

A plan must be developed and implemented to prevent construction debris

SECTION 01 57 19.02 Page 5 from entering or remaining in the marine environment during the project.

A contingency plan must be in place for the removal and adequate securing of equipment in the event of approaching storms.

When piloting vessels, vessel operators must be vigilant to watch for turtles or other protected marine species. If protected marine species are spotted, operators shall halt or alter course in order maintain at least 150 feet from these species. Vessel operators must reduce speeds to 10 knots or less when within 150 feet of protected marine species. If despite efforts to maintain the distances and speeds described above, a marine species approaches the vessel, put the engine in neutral until the animal is at least 50 feet away, and then slowly move away to the prescribed distance.

All marine equipment (barges, drill rigs, dredging equipment, etc.) must be inspected and cleaned of pollutants, organic matter, and invasive species prior to mobilization. Ensure that equipment and gear will be clean and free of soil, seeds, plant and animal material (terrestrial and aquatic) that could become established as non-native (noxious, invasive).

3.1.5 Natural Resources Management Procedures

Construction Contractor(s) will be responsible for damage or adverse impacts to biological resources that occur as a direct result of construction activities outside the limits of construction.

a. Equipment or personnel must not move outside the designated construction zone. The Contractor will be responsible for all materials and labor for the repair of all unauthorized vegetation impacts.

Damaged vegetation replacement will occur onsite and require maintenance and monitoring comparable to the landscape requirements.

b. Ensure the project limits remain clearly staked throughout construction. Immediately notify the Government if threatened or endangered species are present at the project site.

c. Brown Tree Snakes (BTS) may be encountered at the construction sites and also in construction materials cargo. If the Contractor encounters a BTS, the Contractor is authorized to capture and exterminate the BTS and dispose of it. The BTS is a mildly venomous snake and caution should be exercised if capturing and exterminating the snake.

d. Control and minimize erosion and siltation of off-site areas during construction, particularly adjacent to off-site sensitive biological resources.

e. During construction, field crews will refer environmental issues, including wildlife removal, relocation, dead or sick wildlife, or questions about avoiding environmental impacts, to the Government.

f. Use existing and designated access roads only for construction vehicles.

g. Place staging areas within designated staging sites or inside the limits of construction.

h. Fueling and maintenance of equipment will take place within existing paved areas or the identified laydown area, but not closer than 100 feet to drainages.

SECTION 01 57 19.02 Page 6

i. Cleaning of vehicles and equipment will take place off-site to the greatest extent possible. If washing must occur on-site, designated bermed wash areas must be used to prevent wash water contact with storm water, creeks, rivers, and other water bodies.

j. Appropriate Native and non-invasive species will be planted in all new landscapes (including range berms) upon completion of proposed construction activities. Plants to be used will be selected from a list of recommended and approved plants identified in the Guam Landscaping Guidelines (latest version). All substitutions must be approved in advance by NAVFAC Natural Resources. This is to prevent the introduction and spread of non-native invasive species and to ensure that appropriate native plants are selected.

3.2 BIOLOGICAL MONITORING

a. The Contractor must monitor the biological resources at Sasa Bay to ensure that construction actions (e.g., dredging) do not increase sedimentation or otherwise adversely affect the resources at this location. Pre-construction, during construction, and post-construction surveys must be conducted.

b. Surveys must be conducted once prior to in-water construction activity, twice during construction, and once post-construction.

c. Biological monitoring will consist of transects with photo-quadrats to document the condition of corals in Sasa Bay.

d. The Contractor will prepare a Biological Monitoring Plan that will be reviewed and approved by the Government prior to implementation of surveys. The Biological Monitoring Plan must comply with permit requirements (e.g., ACE permit).

e. After each survey the Contractor will provide electronic copies of all photographs and a brief summary report summarizing the findings.

f. Upon completion of the final survey the Contractor will provide a report summarizing the methods and results; an electronic copy of all photographs will be submitted with the final report. A draft report will be submitted to the Contracting Officer within 2 weeks of completion of the final survey. A final will be delivered to the Contracting Officer within 2 weeks of receipt of comments.

3.3 WATER QUALITY MONITORING (WQM) PLAN

a. The Contractor must continuously monitor to ensure that control measures are in place and functioning properly. If a plume is observed outside of the silt curtain, which caused by the construction activity, the Contractor must stop the activity that is causing the problem and take immediate corrective action. Activity may resume after problem is corrected.

b. The Contracting Officer must conduct daily visual observation. If the Contracting Officer observes a breach in the control measures or observes plume outside the silt curtain, the Contractor will be notified immediately. Upon notification, the Contractor must take immediate corrective action.

SECTION 01 57 19.02 Page 7

c. The Contractor must conduct water quality monitoring to ensure that water quality standards are not violated during the in-water work of the repair project. Pre-construction, during construction, and post-construction sampling/testing must be conducted. Parameters to be tested are turbidity, total suspended solids and pH. A field meter will be used to monitor parameters listed or the appropriate EPA test methods will be used. Quality assurance/quality control must be in accordance with each appropriate method. There shall be two control stations and two monitoring stations. The two control stations must be located away from approximately three feet outside of the silt curtain.

d. Pre-construction: Daily sampling for two weeks must be conducted during the pre-construction phase. Results of the pre-construction monitoring will be used as the baseline for comparing results obtained during the construction and post-construction phase.

e. During construction: For the duration of the in-water work, turbidity will be collected in real time, continuously. The turbidity data will be monitored every 60 minutes. For total suspended solids and pH, sampling will be three times per week, while in-water work is ongoing.

Results will be compared to the pre-construction test results to determine whether or not the construction activity is in compliance with the water quality standards.

f. Post-construction: Post-construction sampling will be done once, two weeks after construction completion.

g. During the water sample collection, the following information must be recorded:

(1) Date and time.

(2) Depth of turbidity reading and name of person conducting hourly turbidity monitoring.

(3) Weather conditions (i.e. rainy, sunny, cloudy, etc.)

(4) Type of construction activity occurring and the construction management techniques being used to prevent/minimize water quality impacts.

(5) Any adjacent operations, which may have occurred and may have contributed to receiving water conditions (e.g., silt suspension, due to propeller of a passing vessel).

h. Reporting: The Contractor must submit weekly Water Quality Reports summarizing the results, along with the laboratory sheets and information obtained during the water sample collection, to the Contracting Officer.

3.4 STORMWATER

3.4.1 Storm Water Notice of Intent for Construction Activities and Storm Water Pollution Prevention Plan (SWPPP)

The Contractor must submit a Storm Water Notice of Intent (NOI) for Storm Water Discharges Associated with Construction Activity under an NPDES General Permit and a site-specific Storm Water Pollution Prevention Plan (SWPPP) for the project to the Contracting Officer prior and gain approval

SECTION 01 57 19.02 Page 8 prior to the commencement of work.

(1) Filing of Project Notice of Intent (NOI):

Under the NPDES Storm Water Program, the Contractor is required to file a Project NOI electronically with USEPA via their website (http://cfpub.epa.gov/npdes/stormwater/enoi.cfm), at least 14 calendar days prior to start of construction for projects under the USEPA Construction General Permit.

Prior to filing the Project NOI with USEPA, the Contractor must submit the NOI, along with the site-specific SWPPP to the Contracting Officer for review and approval at least 30 days prior to start of construction activities. Provide a copy of the NOI to the Contracting Officer as part of storm water compliance submittal requirement prior to start of work. If changes are made to the original NOI, an amended NOI will be required for submittal to the USEPA. Submit a revised or amended NOI for approval to the Contracting Officer prior to filing with the USEPA. All amendments must be submitted to the Contracting Officer at least 7 calendar days prior to submittal to USEPA. Upon receiving approval from the Contracting Officer, file the amended NOI with USEPA.

(2) Contractor NOI and site-specific SWPPP Submittal:

Prepare and submit the Project NOI and site-specific SWPPP in accordance with the Contract requirement and the Comprehensive SWPPP prior to start of construction, within 30 calendar days after contract award.

Upon receipt of the NOI and site-specific SWPPP from the Contractor, the Contracting Officer will review the submittal. The Contractor will not be permitted to begin ground or soil disturbing activity or work that may potentially impact water resources without a Government-approved site-specific SWPPP and Construction General Permit coverage.

A project may entail both ground disturbing and on-ground disturbing activities. No ground disturbing activity will be allowed to proceed without an approved site-specific SWPPP and NOI filed with USEPA. As a follow up to the initial site-specific SWPPP, submit to the Contracting Officer, amendments and updates to site-specific SWPPP (i.e. updated BMP maps), on a regular basis, as project progresses forward to reflect the changes in site conditions and implementation of the BMPs.

Maintain a copy of an approved site-specific SWPPP and updates/amendments at the project site, in addition to the applicable USEPA Construction General Permit, the Project NOI and required stormwater pollution prevention program records, as required under the USEPA Construction General Permit.

Comply with all applicable sections of 22 Guam Annotated Regulations (GAR) Division II, Chapter 10, Guam Soil Erosion and Sediment Control Regulations.

The Contractor must file for permit coverage and file a Notice of Termination once construction is complete and the site is stabilized with a final sustainable cover.

Install, inspect, maintain best management practices (BMPs), and submit stormwater BMP inspection reports and project-specific stormwater pollution prevention plan inspection reports. Ensure construction operations and management are constantly in compliance with the terms and conditions of

SECTION 01 57 19.02 Page 9

USEPA Construction general permit.

The site-specific SWPPP must:

a. Identify potential sources of pollution which may be reasonably expected to affect the quality of storm water discharge from the site.

b. Describe and ensure implementation of practices which will be used to reduce the pollutants in storm water discharge from the site.

c. Ensure compliance with terms of the USEPA Construction general permit for storm water discharge.

d. Select applicable best management practices the Final Comprehensive Construction Stormwater Pollution Prevention Plan, dated September 2010.

e. Include a completed copy of the Registration Statement, BMP Inspection Report Template and Notice of Termination except for the effective date.

f. The site-specific SWPPP for the project must be approved by the Contracting Officer prior to the commencement of work. The site-specific SWPPP must meet the requirements of the general permit for storm water discharges from construction sites. Keep a copy of the approved site-specific SWPPP at the construction on-site office, and continually updated as regulations require reflecting current site conditions.

3.4.2 Inspection Reports

Submit Storm Water Inspection Reports for Construction General Permit (CGP) to the Contracting Officer once every 7 calendar days and within 24 hours of a storm event that produces 12 mm or more of rain.

3.5 BEST MANAGEMENT PRACTICEs (BMPs)

Submit a Best Management Practices (BMPs) Plan summarizing BMPs proposed for use on the project and how they will be implemented. Conform to both Best Management Practices (BMPs) utilizing 10 GCA CH45, 10 GCA CH46, 10 GCA CH47, 10 GCA CH49, 10 GCA CH50, 10 GCA CH51, 10 GCA CH52, 10 GCA CH53 and section 402 of the Clean Water Act. Comply with all Federal and applicable local environmental rules and regulations. The Contractor must meet with the Contracting Officer to discuss the proposed BMPs and develop an initial understanding relative to the details of the BMPs.

The purpose of BMPs are to ensure that all aspects of the project construction is performed in a manner to prevent/minimize environmental impacts during construction activity. Protective practices include:

a. Implement applicable Best Management Practice to prevent containment of storm water runoff from all areas affected by construction. Best Management Practice include, but are not limited to, protecting storm drain inlets and other drainage facilities, performing regular cleaning to keep areas exposed to storm water clean and free of rubbish, construction debris, spills; storing material under shelter or covering material to avoid contact with storm water; enclosing outdoor sanding and painting operations to contain and collect waste; use a suction device when chipping/grinding or frequently vacuuming/cleaning waste from sanding and painting operations; controlling spills; install containment; providing a berm or dike around critical areas; and

SECTION 01 57 19.02 Page 10 containment; providing a berm or dike around critical areas; and implementing erosion and sediment control measures.

b. For all work occurring in, over, or near harbor waters, no debris shall be allowed to enter the water. During the performance of the work, the Contractor must institute and enforce procedures to prevent debris, construction materials, and spills from fouling the waters. The Contractor must provide temporary platform or other suitable positive means of capturing debris from construction, demolition, and surface preparation (painting, chipping, and grinding) operations. The Contractor must provide full water depth silt curtains to fully enclose areas. The silt curtains must be in-place and approved by the Contracting Officer before conducting any of this type of work, and such facilities must remain in place until removal is authorized by the Contracting Officer before conducting any of this type of work, and such facilities must remain in place until removal is authorized by the Contracting Officer. If such procedures fail, the Contractor must promptly notify Contracting Officer and clean-up all spills and debris.

The Contractor must immediately evaluate failed procedures and take corrective measures to fix all deficiencies.

c. Monitoring: Daily visual inspection of the construction site must be performed to ensure that the construction activities do not result in adverse impacts.

d. Take into consideration the requirements of 10 GCA CH45, 10 GCA CH46, 10 GCA CH47, 10 GCA CH49, 10 GCA CH50, 10 GCA CH51, 10 GCA CH52, and 10 GCA CH53 to prevent the release of dust from construction operation, including but not limited to sandblasting. Submit a Dirt and Dust Control Plan for containment measures (plastic or canvas screens, vacuum attachments, etc.) of dust emission for approval by the Contracting Officer.

3.6 PROTECTION OF CULTURAL RESOURCES/HISTORIC PROPERTIES

Consultations under Section 106 of the National Historic Preservation Act (NHPA) have been completed by the Government. A determination of no adverse impact has been received for the project from the State Historic Preservation Office provided requirements listed herein are met. No cultural resource/archaeological monitoring is required.

Prior to start of construction, Contractor and subcontractor personnel must attend an annual Cultural Resources Training provided by the Government's Cultural Resource Specialist.

All Contractor personnel must comply with applicable federally mandated cultural resource mitigation agreements and discovery procedure guidance for an inadvertent find such as archaeological materials or human burials.

The Government will utilize an archaeological services contractor to investigate and advise on any inadvertent archaeological materials or human burial finds. The name and contact information for the archaeological services contractor will be announced at the pre-construction conference, where the archaeological services contractor may give a presentation that explains the purpose and methodology for carrying out the archaeological mitigation and what to do if archaeological materials or human remains are inadvertently discovered during construction.

The Contractor must coordinate scheduling of all subsurface and horizontal

SECTION 01 57 19.02 Page 11 groundwork with the Government's archaeological services contractor.

In the event of inadvertent discoveries during any ground disturbance activities, the undertaking will be subject to 35 CFR 800.13 (Post-review Discoveries). Upon encounter (all cultural deposits or human skeletal remains discovered in the course of work), work must cease in the immediate area and the discovery must be protected in-place and reported immediately to the Contracting Officer. Work cannot continue in the immediate area of the discovery until directed by the Contracting Officer to resume work.

Obtain direction from the Contracting Officer to erect temporary high-visibility plastic mesh with rebar post fencing around the discovery (with Government-designated buffer) prior to the start of Government archaeological recovery work in the area. The Government retains ownership and control over historical and archaeological resources.

3.6.1 Crane Rails

Existing crane rails are classified as historic and are subject to the requirements of 36 CFR Part 68, THE SECRETARY OF THE INTERIOR'S STANDARDS FOR THE TREATMENT OF HISTORIC PROPERTIES . Crane rails must be removed, cleaned, tagged to note the location the rail was located, and stored in a secure area away from ground moisture for re-installation. Crane rails must be re-installed as indicated in the contract documents and Section 106 NHPA Consultation. Sections of rail that have incurred greater than 20% section loss due to corrossion must be replaced in-kind to match existing profile and material where possible. As-built plans shall distinguish between lengths of the rail which are original and those which are replaced.

3.7 MUNITIONS AND EXPLOSIVES OF CONCERN (MEC)/MATERIAL POTENTIALLY

PRESENTING AN EXPLOSIVE HAZARD (MPPEH)

The Contractor will be required to adhere to the Joint Region Marianas - Explosive Safety Submission (JRM-ESS), current amendment series and applicable references indicated.

3.7.1 Low (green) Probability Areas

QUESTION (Q) 39: MEC – Reference RFP Part A, SF1442, Price Proposal Schedule, SubCLIN 0001L Base Bid Item L - MEC Clearance:

SubCLIN 0001L Base Bid Item L MEC Clearance states, “Total price for the entire work to provide all necessary labor, material, transportation, supervision, equipment, and other incidental work required in accordance with Specification 01 57 19.01 20, complete and in accordance with the Request for Proposal.

These costs include, but are not necessarily limited to, MEC equipment and personnel mobilization/ demobilization, MEC work plans, MEC reporting, MEC Personnel, MEC safety briefings and awareness training, reduced production rates associated with debris removal, equipment, scanning, additional costs to shield equipment operators, dredge spoils drying, screening and/or broadcasting, equipment and scanning, and anomaly clearance.”

According specification section 01 57 19.01 20 paragraph 3.7.1 Low (green) Probability Areas, “The work is located in an area with low (green) probability of encountering MEC/MPPEH. Military EOD will be on-call for MEC/MPPEH construction support.”

Given the direction provided in specification section 01 57 19.01 20, the Military EOD will be on-call for MEC/MPPEH construction support and therefore the contractor will not be responsible for MEC/MPPEH clearing if encountered. Please delete SubCLIN 0001L because the MEC Clearance scope of work is not required.

Answer (A) 39 (REVISED): MEC Clearance includes in water activities. Specification section 01 57

19.01 20 SUPPLEMENTAL TEMPORARY ENVIRONMENTAL CONTROLS has been revised to clarify the requirements. Refer to RFP Amendment 0004 0005.

Q94: Relevant Construction Experience Magnitude – Reference RFP Part A, SF1442, Factor 1 Experience, Paragraph (a), Item (i):

Current past experience for projects required in the RFP is $40 million. The portion of the wharf face and new pier construction involved in the stated work can be showcased on a number of projects that are performed with a minimum value of $25 million, with work predominantly relevant to the scope of work on this project. Please lower the value of past projects to $25 million, with the scope of work relevant to the scope being included in this RFP.

A94: The $40 million threshold remains unchanged. For clarification of the dollar value of past projects in Factor 1 Experience, offerors should include all costs associated with each submitted construction project. The total construction cost includes costs related to the complete structural replacement of a wharf face or the construction of a new pier and costs associated with other work that may be required under the project.

Q95: Relevant Construction Experience Timeframe – Reference RFI Notice 1 Response to Question 1:

Government’s RFI Notice 1 answer in response to Question 1 states that the 10-year timeframe for relevant construction experience will not be increased. Limiting consideration of the bidder’s relevant construction experience to only that within the past 10 years seems to be overly restrictive which unnecessarily thwarts open competition and bid participation by qualified local contractors with large scale wharf construction and harbor dredging experience. Thus, the limited timeframe appears contrary to the full and open competition requirements of 41 U.S.C. Section 253(a)(1)(A).

Assuming he Government’s RFP objective is to obtain the best overall value to the Government in terms of price and proven Naval Base Guam performance capability, will the Government consider extending the references requirement for relevant construction experience from 10 to 15 years to allow bid participation by qualified local contractors, increase the number of competitive bid offers, and insure full and open competition in compliance with 41 U.S.C. Section 253(a)(1)(A)?

A95: Timeframe for relevant construction experience is changed from 10 years to 15 years. Refer to RFP Amendment 0006.

Q99: Site Visit – Reference RFP Part B, Specification Section 01 14 00 Work Restrictions, Paragraph

1.3 Special Scheduling Requirements, Item f:

Paragraph f. states, “The Government will be responsible for obtaining the project-specific MEC ESS annex for in-water intrusive activities.”

Without an in-water ESS, bidders are unable to quantify the MEC related scope of work, costs, and impacts on in-water construction operations. In-water intrusive activities such as pile driving and dredging are equipment intensive operations so any inefficiencies introduced from MEC procedures can have significant cost and schedule impacts. We recommend the Government provide a draft or sample in-water ESS from another similar NAVFAC project from Hawaii or the West Coast so that all bidders have the same document outlining the requirements for managing MEC for in-water construction activities.

Please provide clear direction on how MEC for in-water construction activities shall be handled by the Contractor.

A99 (REVISED): Specification section 01 57 19.01 20 SUPPLEMENTAL TEMPORARY ENVIRONMENTAL CONTROLS has been revised to clarify the requirements. Refer to RFP Amendment 0004 0005.
